The following description of the embodiments is merely intended to provide a better understanding of the application by showing examples of the application.

Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

Accordingly, it is intended that the present application covers the modifications and variations of this application provided they come within the scope of the appended claims (the claims) and their equivalents. The embodiments provided by the embodiments of the present application may be combined with each other without contradiction.
The embodiment of the application provides a display compensation method, a device, equipment and a storage medium of a display panel, and the display compensation method, the device, the equipment and the storage medium of the display panel provided by the embodiment of the application are described below with reference to drawings.
First, a display compensation method for a display panel provided by an embodiment of the present application is described.
As shown in FIG. 1, the display compensation method of the display panel provided by the embodiment of the application can comprise S110-S120.
S110, converting original compensation data of a display panel into first compensation data, wherein the first compensation data comprises brightness parameters and chromaticity parameters;
s120, respectively compressing the brightness parameter and the chromaticity parameter according to different compression ratios.
The specific implementation of each of the above steps will be described in detail below.
According to the display compensation method of the display panel, on one hand, original compensation data of the display panel are converted into first compensation data comprising brightness parameters and chromaticity parameters, so that the brightness parameters and the chromaticity parameters are separated, and mutual interference is avoided. On the other hand, the larger the compression ratio is, the larger the data loss is, and the luminance parameter and the chrominance parameter can be compressed according to the requirement by respectively compressing the luminance parameter and the chrominance parameter according to different compression ratios. For example, in the case where the accuracy requirement for the luminance parameter is high, the luminance parameter may be compressed at a relatively small compression rate and the chrominance parameter may be compressed at a relatively large compression rate, and in the case where the accuracy requirement for the chrominance parameter is high, for example, the chrominance parameter may be compressed at a relatively small compression rate and the luminance parameter may be compressed at a relatively large compression rate. Therefore, according to the embodiment of the application, the compression rate of the brightness parameter and the chromaticity parameter can be flexibly set according to the requirement, so that the overall compression rate can be improved while the accuracy of data is ensured.
The display panel may be an Organic LIGHT EMITTING (OLED) display panel, or other types of display panels, for example.
Before introducing S110, as shown in fig. 2, the display compensation method of the display panel may include steps 01 to 05, wherein step 04 may include S110 and S120 shown in fig. 1.
And step 01, collecting optical data of the display panel.
Specifically, the display panel can be first lightened, and the optical equipment is utilized to optically shoot the display panel so as to collect the optical data of the display panel. By way of example, the optical data may include luminance data and color coordinate data of the display panel, and the like.
And step 02, optical data analysis.
For example, luminance data, color coordinate data, etc. of different areas in the display area may be compared for optical data analysis.
And step 03, performing compensation operation to obtain original compensation data.
For example, compensation operation can be performed on the display panel according to the analyzed optical data to obtain compensated data of the display panel. In order to distinguish the compensated data under different color coding formats, the compensated data obtained by performing the compensation operation on the display panel may be referred to as original compensation data.
Step 04, converting the original compensation data into first compensation data and compressing.
Step 04 may include steps S110 and S120, and steps S110 and S120 are described above and are not described here. The color-coded format of the first compensation data may be different from the color-coded format of the original compensation data.
And step 05, converting the compressed brightness parameter and the compressed chromaticity parameter into second compensation data and storing the second compensation data.
The color coding format of the second compensation data is a color coding format supported by the display panel. For example, the number of the cells to be processed,
For example, the compressed data obtained finally can be written into the flash corresponding to the display panel.
But may be stored in other types of memory as well, as the application is not limited in this regard. For example, the demura device may be used to control the display driver chip (DISPLAY DRIVER IC, DDIC) to burn the second compensation data into the single plug-in flash chip, and in normal use, the DDIC first reads the second compensation data from the plug-in flash chip into the energy storage (Random Access Memory, RAM) in the DDIC after the power is turned on, and then converts the normal display data sent by the main control chip according to the second compensation data and sends the converted normal display data to the display panel. It is understood that in the case where the second compensation data is compressed data, the second compensation data should be decompressed, and normal display data may be converted according to the decompressed second compensation data conversion.
A specific implementation of each of the above steps is described below.
S110 is first introduced.
For example, the display panel may include sub-pixels of different colors, the sub-pixels may display a picture at a plurality of gray scales, and the original compensation data may include original compensation data corresponding to the sub-pixels of each color at the plurality of gray scales, respectively.
The color-coded format of the original compensation data may be different from the color-coded format of the first compensation data. As one example, the color-coded format of the raw compensation data may include an RGB color-coded format. The color-coded format of the first compensation data may include a YUV color-coded format or an HSV color-coded format.
In the YUV color-coded format, "Y" represents the brightness (luminence or Luma), i.e., the gray-scale value, while "U" and "V" represent the chromaticity (Chrominance or Chroma). In the case where the format of the target compensation data includes a YUV color coding format, the luminance parameter may include Y and the chrominance parameter may include UV.
The formulas for the interconversion of RGB color coded format data and YUV color coded format data may be as follows:
Y=0.299R+0.587G+0.114B (1.1)
U=-0.147R-0.289G+0.436B (1.2)
V=0.615R-0.515G-0.100B (1.3)
R=Y+1.14V (1.5)
G=Y-0.39U-0.58V (1.6)
B=Y+2.03U (1.7)
in the HSV color coding format, H represents Hue (Hue), S represents Saturation (Saturation), and V represents brightness (Value). In the case where the format of the target compensation data includes an HSV color coding format, the luminance parameter may include V and the chrominance parameter may include HS.
The formulas for the conversion of RGB color coded format data and HSV color coded format data to each other may be as follows:
Let max be equal to the maximum of R, G, B and min be the minimum. The (h, s, v) values in the corresponding HSV space are:
v=max (2.3)
p=v×(1-s) (2.6)
q=v×(1-f×s) (2.7)
t=v×(1-(1-f)×s) (2.8)
Wherein h i, f, p, q, t are intermediate variables.
Taking the example that the number of displayable bits of the display panel is 8 bits, the range of RGB values can be 0-255.
Next, S120 is described.
The compression ratio may be a ratio of a size after data compression to a size before data compression. For example, 8M data is compressed into 4M data, and the compression rate is 50%.
The compression ratio of the luminance parameter in S120 may be greater than the compression ratio of the chrominance parameter, or the compression ratio of the luminance parameter may be less than the compression ratio of the chrominance parameter.
The display panel may display different brightness, for example, the display panel may display a picture with high brightness and may display a picture with low brightness.
In some embodiments, the first compensation data may include first interval compensation data belonging to a first luminance interval and second interval compensation data belonging to a second luminance interval, and the luminance of the first luminance interval is different from the luminance of the second luminance interval. For example, the brightness of the first brightness interval may be understood as a highlight interval, and the brightness of the second brightness interval may be understood as a low-light interval.
The first interval compensation data includes a first luminance parameter and a first chrominance parameter, and the second interval compensation data includes a second luminance parameter and a second chrominance parameter.
As one example, S120 may include compressing the first luminance parameter and the first chrominance parameter, respectively, at different compression rates and/or compressing the second luminance parameter and the second chrominance parameter, respectively, at different compression rates.
As another example, S120 may include compressing the first luminance parameter and the second luminance parameter, respectively, at different compression rates and/or compressing the first chrominance parameter and the second chrominance parameter, respectively, at different compression rates. As yet another example, as shown in fig. 3, S120 may include S121 and S122.
S121, respectively compressing a first brightness parameter and a first chromaticity parameter according to different compression rates, and respectively compressing a second brightness parameter and a second chromaticity parameter according to different compression rates;
s122, respectively compressing the first luminance parameter and the second luminance parameter according to different compression ratios, and respectively compressing the first chrominance parameter and the second chrominance parameter according to different compression ratios.
It can be understood that, in S121, for the same luminance interval, the compression rates of the luminance parameter and the chrominance parameter corresponding to the luminance interval are different, so that the luminance parameter and the chrominance parameter can be compressed according to the requirement of a single luminance interval, thereby being capable of improving the overall compression rate of the data of the single luminance interval while ensuring the data accuracy of the single luminance interval.
It can be understood that, in S122, for different luminance intervals, the compression ratios of the luminance parameters of the different luminance intervals may be different, and/or the compression ratios of the chrominance parameters of the different luminance intervals may be different, so that the luminance parameters and the chrominance parameters may be compressed according to the overall requirement of the display panel, thereby being capable of ensuring the data accuracy of each luminance interval and being more conducive to improving the overall compression ratio.
In some embodiments, as shown in fig. 4, the brightness of the first brightness interval L1 is greater than the brightness of the second brightness interval L2. In fig. 4, the horizontal axis represents luminance, the vertical axis represents compression ratio, the solid line 1 represents luminance parameter, and the broken line 2 represents chromaticity parameter. It should be noted that the solid line and the dashed line in fig. 4 are only for distinguishing different parameters, and are not used to limit the continuity or discontinuity of data.
The data corresponding to the first luminance interval L1 includes a first luminance parameter and a first chrominance parameter, and the data corresponding to the second luminance interval L2 includes a second luminance parameter and a second chrominance parameter.
The compression ratio of the first luminance parameter may be greater than the compression ratio of the first chrominance parameter, and the compression ratio of the second luminance parameter may be less than the compression ratio of the second chrominance parameter.
Depending on the characteristics of the human eye, the human eye is more sensitive to differences in chromaticity between highlight regions and to changes in luminance between low luminance regions. In the embodiment of the application, the chroma parameters are higher in compression rate for the data in the highlight area, so that the brightness parameters can be reserved as much as possible. For data in low-brightness areas, the brightness parameter adopts higher compression rate, so that the chroma parameter can be reserved as much as possible. Compared with the uniform compression ratio adopted by the brightness parameter and the chromaticity parameter, the embodiment of the application has less data loss under the same compression ratio, thereby enabling the visual effect of the display panel to be better and enabling the display panel to have higher compression ratio under the same visual effect.
For example, the compression ratio of the first luminance parameter may be greater than the compression ratio of the second luminance parameter. That is, the compression rate of the brightness parameter in the high brightness region can be larger than that in the low brightness region, so that the human eye change can be well adapted.
For example, the compression ratio of the first chromaticity parameter may be smaller than the compression ratio of the second chromaticity parameter. That is, the compression rate of the chromaticity parameter in the high brightness region can be smaller than that in the low brightness region, so as to better adapt to human eye variation.
In some embodiments, please continue to refer to fig. 4, as the brightness of the display panel increases, the compression ratio of the brightness parameter may gradually increase, and the compression ratio of the chromaticity parameter may gradually decrease. Because the sensitivity of human eyes to brightness and the sensitivity of chromaticity are gradually changed, the compression ratio of brightness parameters and the compression ratio of chromaticity parameters are gradually changed along with the characteristics of human eyes, so that the visual effect is further improved while the overall compression ratio is improved.
For example, the compression ratio of the luminance parameter may be in a first curve relationship with the luminance of the display panel. For example, as the brightness of the display panel increases, the slope of the first curve may gradually increase.
For example, the compression ratio of the chromaticity parameter and the brightness of the display panel may have a second curve relationship. For example, as the brightness of the display panel increases, the slope of the second curve gradually decreases.
In some embodiments, as shown in fig. 5, the brightness of the first brightness interval L1 is greater than the brightness of the second brightness interval L2. In fig. 5, the horizontal axis represents luminance, the vertical axis represents compression ratio, the solid line 1 represents luminance parameter, and the broken line 2 represents chromaticity parameter. It should be noted that the solid line and the dashed line in fig. 5 are only for distinguishing different parameters, and are not used to limit the continuity or discontinuity of data.
The first luminance section L1 may include a first sub-luminance section L11 and a second sub-luminance section L12, and the luminance of the first sub-luminance section L11 is greater than the luminance of the second sub-luminance section L12.
The first luminance parameter includes a first sub-luminance parameter and a second sub-luminance parameter, the first chrominance parameter includes a first sub-chrominance parameter and a second sub-chrominance parameter, the first sub-luminance parameter and the first sub-chrominance parameter correspond to a first sub-luminance interval L11, and the second sub-luminance parameter and the second sub-chrominance parameter correspond to a second sub-luminance interval L12.
The compression ratio of the first sub-luminance parameter may be equal to the compression ratio of the second sub-luminance parameter, the compression ratio of the first sub-chrominance parameter being smaller than the compression ratio of the second sub-chrominance parameter, the compression ratio of the first sub-luminance parameter being greater than the compression ratio of the second sub-chrominance parameter.
In the embodiment of the application, the brightness parameters of the plurality of subintervals in the highlight interval can share one compression rate while the brightness parameters of the highlight interval are higher, and the chromaticity parameters of the plurality of subintervals in the highlight interval are different, so that the visual effect is not lost, the overall compression rate is further improved, and the storage space is saved.
In some embodiments, please continue to refer to fig. 5, the brightness of the first brightness interval L1 is greater than the brightness of the second brightness interval L2. The second luminance section L2 may include a third sub-luminance section L23 and a fourth sub-luminance section L24, and the luminance of the third sub-luminance section L23 is greater than the luminance of the fourth sub-luminance section L24.
The second luminance parameter includes a third sub-luminance parameter and a fourth sub-luminance parameter, the second chrominance parameter includes a third sub-chrominance parameter and a fourth sub-chrominance parameter, the third sub-luminance parameter and the third sub-chrominance parameter correspond to a third sub-luminance interval L23, and the fourth sub-luminance parameter and the fourth sub-chrominance parameter correspond to a fourth sub-luminance interval L24.
The compression ratio of the third sub-chromaticity parameter may be equal to the compression ratio of the fourth sub-chromaticity parameter, the compression ratio of the third sub-luminance parameter being greater than the compression ratio of the fourth sub-chromaticity parameter, the compression ratio of the third sub-chromaticity parameter being greater than the compression ratio of the third sub-luminance parameter.
In the embodiment of the application, the higher compression rate is adopted for the chromaticity parameters in the low-brightness regions, the chromaticity parameters of the plurality of sub-regions in the low-brightness regions can share one compression rate, and the brightness parameters of the plurality of sub-regions in the low-brightness regions are different, so that the visual effect is ensured to be less lost, the overall compression rate is further improved, and the storage space is saved.
For example, as shown in fig. 5, the maximum compression rate of the luminance parameter and the maximum compression rate of the chrominance parameter may be the same. The minimum compression ratio of the luminance parameter and the minimum compression ratio of the chrominance parameter may be the same. This is of course only an example and is not intended to limit the application.
For example, as shown in fig. 5, while the compression rate of the first sub-chromaticity parameter is smaller than that of the second sub-chromaticity parameter, the compression rate of the first sub-chromaticity parameter may gradually decrease in the first sub-luminance section and the compression rate of the second sub-chromaticity parameter may gradually decrease in the second sub-luminance section as the luminance increases.
As shown in fig. 5, while the compression ratio of the third sub-luminance parameter is greater than the compression ratio of the fourth sub-luminance parameter, the compression ratio of the third sub-luminance parameter may gradually increase in the third sub-luminance interval and the compression ratio of the fourth sub-luminance parameter may gradually increase in the fourth sub-luminance interval as the luminance increases.
The color-coded formats that a display panel can support are typically fixed, and the display panel can directly display based on the data in the color-coded formats that it supports, where "directly displaying" refers to not converting the color-coded formats of the data prior to display.
In some alternative embodiments, after S120, the method provided by the embodiment of the present application may further include converting the compressed luminance parameter and the compressed chrominance parameter into second compensation data and storing the second compensation data, where a color coding format of the second compensation data is a color coding format supported by the display panel.
The second compensation data may be written into a flash corresponding to the display panel for storage, and may be stored in other types of memories.
In the embodiment of the application, the compressed brightness parameter and the compressed chromaticity parameter are converted into the second compensation data and stored, and the second compensation data can be directly called from the storage module when the display panel displays, so that the conversion of the color coding format is not needed, and the display driving efficiency can be improved.
In addition, as described above, the color coding format of the original compensation data is different from the color coding format of the first compensation data, so that the second compensation data is obtained by performing format conversion on the original compensation data and compressing the original compensation data according to different compression rates, and the compression rate of the second compensation data is larger than that of the compressed data obtained by directly compressing the original compensation data, so that the storage space can be saved.
It is understood that the second compensation data is compressed data, and when the display panel displays, the data in the target color coding format can be decompressed and then displayed based on the decompressed data. Illustratively, the color-coded formats supported by the display panel may include RGB color-coded formats.
As one example, the color-coded format of the original compensation data may be an RGB color-coded format, the color-coded format of the first compensation data may be a YUV color-coded format, and the color-coded format of the second compensation data may be an RGB color-coded format.
It is understood that the original compensation data may be non-compressed data and the first compensation data and the second compensation data may be compressed data.
Based on the same inventive concept, the embodiment of the application provides a display compensation device of a display panel. As shown in fig. 6, the display compensation apparatus for a display panel according to an embodiment of the present application may include a data conversion module 601 and a compression module 602.
The data conversion module 601 is configured to convert original compensation data of the display panel into first compensation data, where the first compensation data includes a luminance parameter and a chrominance parameter;
The compression module 602 is configured to compress the luminance parameter and the chrominance parameter according to different compression rates.
According to the display compensation device of the display panel, on one hand, original compensation data of the display panel are converted into first compensation data comprising the brightness parameter and the chromaticity parameter, so that the brightness parameter and the chromaticity parameter are separated, and mutual interference is avoided. On the other hand, the larger the compression ratio is, the larger the data loss is, and the luminance parameter and the chrominance parameter can be compressed according to the requirement by respectively compressing the luminance parameter and the chrominance parameter according to different compression ratios. For example, in the case where the accuracy requirement for the luminance parameter is high, the luminance parameter may be compressed at a relatively small compression rate and the chrominance parameter may be compressed at a relatively large compression rate, and in the case where the accuracy requirement for the chrominance parameter is high, for example, the chrominance parameter may be compressed at a relatively small compression rate and the luminance parameter may be compressed at a relatively large compression rate. Therefore, according to the embodiment of the application, the compression rate of the brightness parameter and the chromaticity parameter can be flexibly set according to the requirement, so that the overall compression rate can be improved while the accuracy of data is ensured.
