In the embodiment of the application, the display equipment can acquire the adjustable power of the display equipment, then carry out power redistribution based on the acquired adjustable power to acquire the adjustment power of each display partition, and finally adjust the power generation power of each display partition to the adjustment power of the display partition, thereby improving the backlight brightness of each display partition by improving the power generation power of each display partition while ensuring the normal operation of the display equipment, and further improving the power utilization rate of the display equipment.
The method for adjusting the generated power according to the embodiment of the application will be described in detail with reference to fig. 1 to 12.
Referring to fig. 1, a flow chart of a method for adjusting generated power is provided in an embodiment of the present application. As shown in fig. 1, the method may include the following steps S101 to S103.
Step S101, obtaining adjustable power of display equipment;
Specifically, the display device may be a terminal device with a display panel, such as an intelligent interactive tablet, a television, a tablet computer, a desktop computer, and a notebook computer. The display device may be preset with at least two display partitions, that is, the display device is divided into at least two areas, each area is a display partition, and each display partition may be labeled to distinguish each display partition, as shown in fig. 2, where the display device is divided into four areas, and there are a first display partition, a second display partition, a third display partition, and a fourth display partition, where the display device is based on a local dimming technology (local dimming technology), and the display device divides a display panel into at least two areas, and equally divides an image signal into at least two areas, then performs analysis and calculation according to the brightness of an image of each area, and finally automatically controls the brightness of a backlight source of each area according to a calculation result, that is, the display brightness value of each display partition in the display device is different, and the display brightness value is different from the power of a display module of the display device. Based on this, in most scenarios, i.e. in scenarios where the power generated for most of the displayed images is much lower than the rated power of the display device, the adjustable power is the power that is not utilized in the display device, where the rated power is the maximum power generated by the display device.
When the display device receives the display image, the display device acquires image information of the display image, calculates predicted power generation for the whole display device to be used according to the image information, then acquires rated power of the display device, calculates a difference between the rated power and the predicted power generation, and takes the difference as adjustable power of the display device, for example, when the rated power of the display device is 50W and the predicted power generation of the display device is 20W, the adjustable power of the display device is 30W.
Step S102, determining the adjustment power of each display partition according to the adjustable power;
specifically, the adjustment power is the area generated power of the display partition after the display device performs power redistribution on the adjustable power, that is, when the display device performs generated power adjustment on the display partition.
The display equipment redistributes the acquired adjustable power so as to obtain the power increment of each display partition, further calculates the current power generation power of each display partition and the sum of the corresponding power increment, and takes the obtained sum value as the adjustment power of each display partition.
Alternatively, the adjustable power may be distributed evenly according to the number of partitions of the display partition, to obtain a power increment of each display partition, and then the power increment is added to the power generated by prediction of each display partition, to obtain an adjusted power of each display partition, for example, when the adjustable power of the display device is 30W and there are 4 display partitions in the display device, the power increment of each display partition is 7.5W, when the power generated by prediction of the first display partition is 5W, the adjusted power of the first display partition is 5+7.5=12.5W, when the power generated by prediction of the second display partition is 9W, the adjusted power of the second display partition is 9+7.5=16.5W, when the power generated by prediction of the third display partition is 2W, the adjusted power of the third display partition is 2+7.5=9.5W, and when the power generated by prediction of the fourth display partition is 4W, the adjusted power of the fourth display partition is 4+7.5=11.5W. The power adjustment proportion of each display partition can also be obtained according to the current display brightness value of the display partition, then the power increment of each display partition is calculated based on the power adjustment proportion of each display partition, then the power increment is added with the current power generation power of each display partition to obtain the adjustment power of each display partition, for example, when the predicted power generation power of the first display partition is 5W and the display brightness value is 7.5, the power adjustment proportion of the first display partition is 0, the power increment is 5*0 =0w, the adjustment power is 5+0 =5w, when the predicted power generation power of the second display partition is 9W and the display brightness value is 13.5, the power adjustment proportion of the second display partition is 0.8, the power increment is 9×0.8=7.2W, the adjustment power is 9+7.2=16.2W, when the predicted power generation power of the third display partition is 2W and the display brightness value is 3, the power adjustment proportion of the third display partition is 0, the power increment is 320=2=0W, the adjustment power is 2+0=4W, when the predicted power increment is 3 and the fourth display brightness value is not equal to the fourth display brightness value, and the power is equal to the fourth display brightness value is equal to the preset value of the preset value, and the power adjustment proportion is not equal to the preset value of the fourth display brightness value, and the preset value is displayed as the limit value, and the display brightness value is equal to the limit to the display proportion to the display brightness value is displayed to the limit to the display proportion to be adjusted to 4.
Step S103, the generated power of each display partition is adjusted to the adjusted power of the display partition.
Specifically, the display device performs power adjustment on each display partition according to the adjustment power of each display partition, that is, adjusts the generated power of each display partition to the corresponding adjustment power.
Alternatively, an adjustment luminance value corresponding to the adjustment power of each display partition may be obtained, and then the area backlight signal is modified according to the adjustment luminance value of each display partition, so that the driving module of the display device performs backlight control according to the modified area backlight signal, thereby adjusting the power generation power of each display partition to the corresponding adjustment power.
In the embodiment of the application, the adjustable power of the display equipment is obtained, then the power redistribution is carried out based on the obtained adjustable power, the adjustment power of each display partition is obtained, finally the power adjustment is carried out based on the adjustment power after the power redistribution, and the backlight brightness of each display partition is improved by improving the power generation power of each display partition while ensuring the normal operation of the display equipment, so that the power utilization rate of the display equipment is improved.
Referring to fig. 3, a flow chart of a method for adjusting generated power is provided in an embodiment of the application. As shown in fig. 3, the method according to the embodiment of the present application may include the following steps S201 to S204.
Step S201, obtaining the power generation power of each display partition, and obtaining the total power generation power of the display equipment according to each power generation power;
Specifically, the display device may be preset with at least two display partitions, that is, the display device is divided into regions, each region is one display partition, and each display partition may be labeled to distinguish each display partition, as shown in fig. 2, where when the display device is divided into four regions, there are a first display partition, a second display partition, a third display partition, and a fourth display partition in the display device. The power generated by the display section is the power generated in the region corresponding to the display section. The total generated power of the display device may be the sum of the generated power of all the display sections.
The display device firstly acquires the power generated by each display partition, then sequentially accumulates the power generated by each display partition, and takes the obtained accumulated value as the total power generated by the display device.
Optionally, when the display device receives the display image, the received display image is subjected to area division, that is, the received display image is subjected to area division (as shown in fig. 4) according to the area division condition (as shown in fig. 2) of the display device, so as to obtain an image area corresponding to each display partition, the power generation of each display partition is calculated according to the image information corresponding to each image area, and then the total power generation of the display device is calculated according to the power generation of each display partition.
Referring to fig. 5, an exemplary schematic diagram of acquiring the generated power of the display partition is provided in the embodiment of the present application. As shown in fig. 5, the method according to the embodiment of the present application may include the following steps S301 to S302.
Step S301, obtaining a display brightness value of each display partition;
specifically, when the display device receives a display image, the received display image is subjected to area division, namely, the received display image is subjected to area division according to the area division condition of the display device, so that an image area corresponding to each display area is obtained, and the display brightness value of each display area is calculated according to the image information corresponding to each image area.
Step S302, the power generation power of each display partition is obtained according to the corresponding relation between different display brightness values and different power generation powers and the display brightness value of each display partition.
Specifically, a mapping relationship between display luminance values and generated power is stored in a storage medium of the display device, and each display luminance value has its corresponding generated power. The display equipment sequentially acquires the power generation power corresponding to the display brightness value of each display partition according to the mapping relation between the display brightness value and the power generation power, and takes the power generation power corresponding to the acquired display brightness value as the power generation power of the display partition. For example, the mapping relationship between the display luminance value C and the generated power P may be a mapping function curve (as shown in fig. 6), and the process of obtaining the generated power corresponding to the display luminance value C3 in the display partition may be to obtain a value on the P axis/vertical axis when the value on the C axis/horizontal axis is 3 in the mapping function curve, and use the obtained value on the P axis/vertical axis as the generated power of the display partition.
The mapping relation between the display brightness value and the power generation power is set, the display brightness value of each display partition is calculated first, and then the power generation power corresponding to each display brightness value is obtained, so that the power generation power of each display partition is obtained, the situation that images are displayed first and the power generation power of the display partition is counted based on the current display situation is avoided, and the speed of obtaining the power generation power is improved.
Referring to fig. 7, an exemplary schematic diagram of acquiring total generated power of a display device is provided in an embodiment of the application. As shown in fig. 7, the method according to the embodiment of the present application may include the following steps S401 to S402.
Step S401, adding the generated power of each display partition to obtain the generated power of the display equipment;
specifically, the display device adds the generated power of each display section one by one, and takes the resulting accumulated value as the generated power of the display device. For example, when the power generation power of the first display section is 5W, the power generation power of the second display section is 9W, the power generation power of the third display section is 2W, and the power generation power of the fourth display section is 4W, the power generation power of the display device is 5+9+2+4=20w.
Step S402, multiplying the generated power of the display equipment by a deviation coefficient to obtain the actual generated power of the display equipment, and taking the actual generated power as the total generated power of the display equipment;
The deviation coefficient is the deviation ratio between the generated power when the display device and the sample device display the same brightness value.
Specifically, due to objective reasons such as production process, there is a certain difference in hardware between different display devices, so that the mapping situation between the display brightness value and the generated power of each display device is not consistent. The display device receives the mapping relation between different display brightness values and different power generation powers of the sample device and also receives the deviation coefficient of the display device and the sample device, wherein the mapping relation and the deviation coefficient are factory parameters of the display device and are constant values.
The display device acquires the deviation coefficient stored in the storage medium, multiplies the acquired power generation of the display device by the deviation coefficient, and takes the obtained product as the actual power generation of the display device, that is, the total power generation of the display device.
For example, the total generated power of the display device may be calculated according to the following formula:
p=(py1+py2+py3+......+pyx)*k
Wherein, p is the total power generated by the display device, py1 is the power generated by the first display partition when the display brightness value is y, y is the current display brightness value of the first display partition, and similarly, py2 is the power generated by the second display partition when the display brightness value is y, y is the current display brightness value of the second display partition, and so on, and k is the deviation coefficient of the display device.
The actual power generation power of the display equipment is calculated according to the deviation coefficient and the power generation power of the display equipment, so that the calculation error of the power generation power caused by the difference between the display equipment and the sample equipment is reduced, and the accuracy of the obtained total power generation power of the display equipment is improved.
Step S202, the rated power of the display equipment is obtained, and the adjustable power of the display equipment is obtained according to the total generated power and the rated power.
Specifically, the rated power of the display device refers to the maximum power generated by the display device, and the rated power is a factory parameter of the display device and is a constant value.
The display device obtains rated power, and then calculates adjustable power of the display device according to the total generated power of the display device and the rated power of the display device.
Alternatively, a difference between the rated power and the total generated power of the display device may be calculated, and then the calculated difference obtains the adjustable power of the display device, for example, when the rated power of the display device is 50W and the predicted generated power of the display device is 20W, the adjustable power of the display device is 30W.
Referring to fig. 8, an exemplary schematic diagram of obtaining adjustable power of a display device is provided in an embodiment of the application. As shown in fig. 8, the method according to the embodiment of the present application may include the following steps S501 to S502.
Step S501, a first power difference value between rated power and total generated power is obtained;
Specifically, the first power difference is a difference obtained by subtracting the current calculated total generated power of the display device from the rated power of the display device, i.e. the power which is not utilized in the display device. For example, when the rated power is 50W and the total generated power of the display device is 20W, the first power difference is 30W.
Step S502, taking the product of the first power difference value and the power adjustment proportion as the adjustable power of the display device.
Specifically, the power adjustment ratio refers to the ratio of the power that can be used for adjusting the generated power in the display device, and the ratio of the power that is occupied in the unused rated power is a preset ratio of the display device, and may also be a ratio set by a user.
The first power difference is multiplied by the power adjustment ratio and the resulting product is the power in the display device that can be used for generating power adjustment, i.e. the adjustable power of the display device. For example, when the first power difference is 30W and the power adjustment ratio is 0.8, the adjustable power of the display device is 24W.
Illustratively, the adjustable power of the display device may be derived according to the following equation:
△p=(P0-p)*n
Wherein Deltap is the adjustable power of the display device, P0 is the rated power of the display device, P is the total power generation power of the display device, and n is the power adjustment ratio.
In the embodiment of the application, the power adjustment proportion is set, so that the condition that the actual total power generation power of the display equipment is equal to rated power for a long time and the hardware damage to the display equipment is avoided.
In the embodiment of the application, the accuracy of the calculated total power generation power of the display equipment is improved by acquiring the power generation power of each display partition and then calculating the total power generation power of the display equipment according to the power generation power of each display partition, so that the accuracy of the calculated adjustable power of the display equipment is improved.
Referring to fig. 9, an embodiment of the present application provides a method for adjusting generated power. The method of the embodiment of the present application may include the following step S601 to step S606.
Step S601, taking the product of the display brightness value of each display partition and the brightness adjustment coefficient as the brightness enhancement value of each display partition;
Specifically, the display device may be preset with at least two display partitions, that is, the display device is divided into regions, each region is one display partition, and each display partition may be labeled to distinguish each display partition, as shown in fig. 2, where when the display device is divided into four regions, there are a first display partition, a second display partition, a third display partition, and a fourth display partition in the display device. Since the power redistribution of the adjustable power by the display device is to increase the display brightness value of the display partition, it can be understood that the brightness adjustment coefficient refers to the proportion of the display brightness value increased by the display partition to the initial display brightness value of the display partition, the brightness adjustment coefficient is smaller than 1, and the initial value of the brightness adjustment coefficient can be constantly 0.2, or can be set by the user. The luminance-increasing value refers to a difference between a display luminance value after luminance increase and a display luminance value before luminance increase (display luminance value at the beginning of the display division) of the display division.
The display equipment calculates the brightness lifting value of each display partition one by one, namely, acquires the display brightness values of the display partitions one by one, multiplies the currently acquired display brightness values by the brightness adjusting coefficient, and takes the obtained product as the brightness lifting value of the current display partition until all the display partitions are traversed. For example, when the display luminance value is C i and the luminance adjustment coefficient is l, the luminance increase value is l×c i.
Step S602, taking the sum of the display brightness value and the brightness lifting value of each display partition as the adjustment brightness value of each display partition;
specifically, the brightness value is adjusted to be the display brightness value of the display partition after brightness is increased.
The display device calculates the adjustment brightness value of each display partition one by one, namely, acquires the display brightness value and the brightness lifting value of the display partition one by one, then adds the currently acquired display brightness value and the brightness lifting value, and then takes the obtained sum value as the adjustment brightness value of the current display partition until all the display partitions are traversed.
Illustratively, the adjusted luminance value for each display section may be calculated according to the following formula:
C'i＝Ci+l*Ci
Wherein, C' i is the adjusting brightness value of the I display partition, C i is the current display brightness value of the I display partition, and l is the brightness adjusting coefficient.
Step S603, obtaining initial adjustment power of each display partition according to the corresponding relation between different display brightness values and different power generation powers and the adjustment brightness value of each display partition;
specifically, the initial adjustment power refers to the generated power corresponding to the adjusted brightness value calculated according to the current brightness adjustment coefficient.
The storage medium of the display device stores a mapping relation between display brightness values and generated power, and each display brightness value has the corresponding generated power. The display equipment sequentially acquires the generated power corresponding to the adjustment brightness value of each display partition according to the mapping relation between the display brightness value and the generated power, and takes the generated power corresponding to the acquired adjustment brightness value as the initial generated power of the display partition.
Step S604, obtaining the total adjustment power of the display device according to each initial adjustment power;
specifically, the total adjustment power refers to the actual power generated by the whole display device after each display partition in the display device performs brightness improvement.
The display equipment accumulates the initial power generation powers of all the display partitions acquired at present one by one, and the accumulated value is taken as the total adjustment power of the display equipment.
Referring to fig. 10, an exemplary schematic diagram of acquiring total adjustment power of a display device is provided in an embodiment of the application. As shown in fig. 10, the method of the embodiment of the present application may include the following steps S701 to S702. Step S701, obtaining a second power difference value between the initial adjustment power and the generated power of each display partition;
Specifically, the second power difference value is a power increment corresponding to the display partition when the display device adjusts the generated power. For example, when the generated power of the display section is p xi', the initial adjustment power of the display section is p yi, and the second power difference of the display section is p xi'-pyi.
Step S702, adding each second power difference value to obtain the total adjustment power of the display device.
For example, the total regulated power of the display device may be derived according to the following formula:
△P=(px1'-py1)+(px2'-py2)+......+(pxi'-pyi)
ΔP is total adjustment power of the display device, P x1' is power generated when the adjustment brightness value of the first display partition is x, x is the adjustment brightness value of the first display partition, P x2 is power generated when the adjustment brightness value of the second display partition is x, x is the adjustment brightness value of the second display partition, and so on, P y1 is power generated when the display brightness value of the first display partition is y, y is the display brightness value of the first display partition, and similarly, P y2 is power generated when the display brightness value of the second display partition is y, y is the current display brightness value of the second display partition, and so on.
In step S605, when the total adjustment power is less than or equal to the adjustable power, the initial adjustment power of each display section is used as the adjustment power of each display section.
Specifically, the display device compares the currently acquired total adjustment power with the adjustable power of the display device, and when the total adjustment power is smaller than or equal to the adjustable power, the initial adjustment power of each display partition calculated in the current process is used as the adjustment power of the corresponding display partition.
For example, the initial adjustment power of the display section is p yi, and when the total adjustment power is less than or equal to the adjustable power, the adjustment power of the display section is p yi.
Step S606, when the total adjusting power is larger than the adjustable power, multiplying the brightness adjusting coefficient with the updating parameter, taking the obtained product as the updated brightness adjusting coefficient, and returning to the step S601.
Specifically, the update parameter refers to a parameter for updating the brightness adjustment coefficient for reducing the current brightness adjustment coefficient, wherein the update parameter is only used for updating the brightness adjustment coefficient and does not change the initial value of the brightness adjustment coefficient.
For example, when the update parameter is s and the initial luminance adjustment coefficient is l, the updated luminance adjustment coefficient l' =l×s.
In the embodiment of the application, the total adjusting power of the display equipment is calculated by calculating the adjusting brightness value of each display partition, and then the total adjusting power of the display equipment is calculated according to the adjusting power corresponding to the adjusting brightness value of each display partition, and finally whether the total adjusting power is smaller than the adjustable power is judged, and further whether further brightness adjustment is carried out is judged, so that the condition that the risk of burning the display equipment is caused when the total adjusting power is larger than the adjustable power is avoided.
Referring to fig. 11, an embodiment of the present application provides a method for adjusting generated power. As shown in fig. 11, the method of the embodiment of the present application may include the following steps S801 to S806.
Step S801, obtaining adjustable power of a display device;
specifically, the adjustable power is power that is not utilized in the display device. See step S101, and will not be described here.
Step S802, obtaining a display brightness value of each display partition;
Specifically, the display device may be preset with at least two display partitions, that is, the display device is divided into regions, each region is a display partition, and each display partition may be labeled to distinguish each display partition, as shown in fig. 2, where when the display device is divided into four regions, there are a first display partition, a second display partition, a third display partition, and a fourth display partition in the display device, a display brightness value is a brightness value of a display module of the display device, and the display device is obtained by calculating according to image information of a display image, and controls backlight brightness of the display module of the display device by controlling power generation power of a driving module of the display device. See step S301, and will not be described here.
Step S803, a display partition with a display brightness value larger than or equal to a preset brightness value is used as a brightness adjustment partition;
The preset brightness value is a judging condition of whether the display partition is used for adjusting the generated power, and it can be understood that when the display brightness value of the display partition is larger than or equal to the preset brightness value, the display partition is subjected to brightness improvement, namely the generated power of the display partition is adjusted, and when the display brightness value of the display partition is smaller than the preset brightness value, the display partition is not subjected to brightness improvement, namely the generated power of the display partition is not adjusted.
The display device compares the display brightness values of the display partitions with preset brightness values one by one, and marks the display partition corresponding to the display brightness value as a brightness adjustment partition when the display brightness value is larger than or equal to the preset brightness value until the display brightness values of all the display partitions are traversed.
For example, when the preset luminance value is 10, the display luminance value of the first display section is 15, the display luminance value of the second display section is 10, the display luminance value of the third display section is 8, and the display luminance value of the fourth display section is 3, the first display section is marked as the first luminance adjustment section, and the second display section is marked as the second luminance adjustment section.
Step S804, obtaining the partition number of brightness adjustment partitions;
Specifically, the display device counts the number of the brightness adjustment partitions.
In order to achieve a better display effect, that is, when most of the display partitions can be used as brightness adjustment partitions, when the display brightness values of all the brightness adjustment partitions are raised, the display brightness values of the whole display device are not different from those of the display device which is directly raised, so that the display brightness values set by a user are greatly different, the display effect of the display device is affected, and a preset partition number is defined, wherein the preset partition number refers to the upper limit of the partition number of the display partitions which can be used as the brightness adjustment partitions.
The display device then compares the partition number of the brightness adjustment partition with a preset partition number, and stops the process of generating power adjustment when the partition number is greater than or equal to the preset partition number.
Step S805, when the partition number is smaller than the preset partition number, acquiring the adjustment power of each brightness adjustment partition according to the adjustable power;
specifically, the adjustment power is the area generated power of the brightness adjustment partition after the display device performs power redistribution on the adjustable power, that is, when the display device performs generated power adjustment on the brightness adjustment partition.
And when the partition number is smaller than the preset partition number, the display equipment redistributes the acquired adjustable power, so that the power increment of each brightness adjustment partition is obtained, the current power generation power of each brightness adjustment partition and the corresponding power increment sum are calculated, and the obtained sum value is used as the adjustment power of each brightness adjustment partition.
Optionally, the adjustable power can be distributed evenly according to the number of the brightness adjustment subareas to obtain the power increment of each brightness adjustment subarea, then the power increment is added with the current power generation power of each brightness adjustment subarea to obtain the adjustment power of each brightness adjustment subarea, the power adjustment proportion of each brightness adjustment subarea can be obtained according to the current display brightness value of the brightness adjustment subarea, then the power increment of each brightness adjustment subarea is calculated based on the power adjustment proportion of each brightness adjustment subarea, and then the power increment is added with the current power generation power of each brightness adjustment subarea to obtain the adjustment power of each brightness adjustment subarea.
For example, the display luminance value of each luminance adjustment partition is obtained, namely, the display luminance value of the first luminance adjustment partition is 15, the display luminance value of the second luminance adjustment partition is 10, then the generated power corresponding to the display luminance value of each luminance adjustment partition is obtained, namely, the generated power of the first luminance adjustment partition is 1.5, the generated power of the second luminance adjustment partition is 1, then the product between the display luminance value of each luminance adjustment partition and the luminance adjustment coefficient is taken as the luminance elevation value of each luminance adjustment partition, the luminance adjustment coefficient is 0.2, namely, the luminance elevation value of the first luminance adjustment partition is 15 x 0.2=3, the luminance elevation value of the second luminance adjustment partition is 10 x 0.2=2, then the sum of the display luminance value of each luminance adjustment partition and the luminance elevation value is taken as the adjustment luminance value of each luminance adjustment partition, namely, the adjustment luminance value of the first luminance adjustment partition is 15+3=18, the adjusted luminance value of the second luminance adjustment partition is 10+2=12, and the corresponding relation between the display luminance value of each luminance adjustment partition and the generated power is taken as the luminance adjustment power of the second luminance adjustment partition is 1.8, wherein the corresponding to the preset luminance adjustment power is 1.8.
Step S806, the generated power of each brightness adjustment zone is adjusted to the adjusted power of the brightness adjustment zone;
specifically, the display device performs power adjustment on each brightness adjustment partition according to the adjustment power of each brightness adjustment partition, that is, adjusts the generated power of each brightness adjustment partition to a corresponding adjustment power.
Alternatively, an adjustment luminance value corresponding to the adjustment power of each luminance adjustment partition may be obtained, and then the area backlight signal is modified according to the adjustment luminance value of each luminance adjustment partition, so that the driving module of the display device performs backlight control according to the modified area backlight signal, thereby adjusting the power generation power of each luminance adjustment partition to the corresponding adjustment power.
In the embodiment of the application, the preset brightness value is set as the judging condition for judging whether the power generation power of the display subarea is regulated, so that the brighter display subarea has higher display brightness value, the contrast ratio between different display subareas is increased, and the overall display effect of the display equipment is further improved.
