Detailed Description
A display system and method provided by the present disclosure will be explained by embodiments below. However, the embodiments are not intended to limit the disclosure to any environment, application, or manner in which the embodiments can be practiced. Accordingly, the description of the embodiments is merely for the purpose of illustrating the present disclosure and is not intended to limit the scope of the present disclosure. It should be understood that in the following embodiments and the accompanying drawings, elements not directly related to the present disclosure have been omitted and are not shown, and the sizes of the elements and the dimensional ratios between the elements are merely exemplary, not to limit the scope of the present disclosure.
In the present embodiment, as shown in fig. 1, the display system DS includes a light emitting device 11, a thermal sensor 13, and an embedded controller 15. In the present embodiment, the thermal sensor 13 is used for sensing an ambient temperature information of the light emitting device 11.
In some embodiments, the thermal sensor 13 may be disposed in the device of the display system DS, on the housing of the display system DS, in the surrounding area of the light emitting device 11, or in the environment by way of an external connection (e.g., a communication connection). In some embodiments, the thermal sensor 13 may communicate ambient temperature information to the embedded controller 15 in a communicative connection.
It should be noted that the Light emitting device 11 may be a Light emitting element (e.g., a backlight bar) of a display screen as known to those skilled in the art. The thermal sensor 13 may be any temperature-detectable sensor. The embedded controller 15 may be various processing units, microprocessors, or other computing devices known to those skilled in the art to which the present disclosure pertains.
In this embodiment, the display system DS receives the ambient temperature information from the thermal sensor 13 in response to receiving a power-on signal (e.g., the power-on signal is received by the embedded controller 15), so as to determine whether the ambient temperature information is lower than a temperature threshold.
In some embodiments, the temperature threshold may be dynamically adjusted. Specifically, the display system DS may dynamically adjust the temperature threshold at the time of implementation based on the normal operating temperatures corresponding to the different driver ICs (DRIVER INTEGRATED circuits), e.g., for some A-type driver ICs, the corresponding temperature threshold may be set to minus 20 degrees. For some B-type drive ics, the corresponding temperature threshold may be set to minus 25 degrees.
In this embodiment, the display system DS determines a first light emitting control signal in response to the ambient temperature information being lower than the temperature threshold, wherein the first light emitting control signal includes a light emitting value and a light emitting time.
In some embodiments, the embedded controller 15 determines the luminance and the lighting time based on a size of a display panel corresponding to the lighting device 11.
For example, the correspondence between the display panel size and the luminance and the light emitting time can be set as shown in the following table 1. When the display panel size is less than 11 inches, the corresponding luminance is 60% and the light emission time is 2 minutes. When the display panel size is between 11 inches and 13 inches, the corresponding luminance is 80% and the lighting time is 2 minutes. When the display panel size is between 13 inches and 15 inches, the corresponding luminance is 100% and the lighting time is 2 minutes. When the display panel size is greater than 15 inches, the corresponding luminance is 100% and the light emission time is 3 minutes.
TABLE 1
In the present embodiment, the light emitting device 11 receives the first light emitting control signal, so that the light emitting device 11 performs a light emitting operation corresponding to the first light emitting control signal. For example, the first lighting control signal may be transmitted to the lighting device 11 by the embedded controller 15 in the display system DS.
For example, when the display panel size is smaller than 11 inches, the light emitting device 11 receives the first light emitting control information corresponding to the luminance of 60% and the light emitting time of 2 minutes, and the light emitting device 11 performs the light emitting operation for maintaining the state of the luminance of 60% for 2 minutes.
For another example, when the display panel is between 13 inches and 15 inches in size, the light emitting device 11 receives the first light emitting control information corresponding to the luminance of 100% and the light emitting time of 2 minutes, and the light emitting device 11 performs the light emitting operation for maintaining the luminance of 100% for 2 minutes.
In some embodiments, the first light-emitting control signal may also include a plurality of luminances and a plurality of light-emitting times, so that the light-emitting device 11 dynamically adjusts the luminances and the light-emitting times of the light-emitting device 11. For example, the light emitting device 11 may perform a light emitting operation in a state where the luminance is 100% for the first 1 minute, and perform a light emitting operation in a state where the luminance is 80% for the following 1 minute.
It should be noted that, if the power-on operation is performed when the temperature of the components (e.g., the driving power source) of the display system DS has not reached the operating temperature, abnormal display may occur (e.g., the display system DS has a black screen or a flower screen), which makes the user experience bad.
In some embodiments, to avoid the foregoing situation, the display system DS performs the operation of logging in to the system after confirming that the lighting operation is completed (i.e., the preheating operation is completed). Specifically, the embedded controller 15 determines whether or not the light emitting device 11 performs the completion of the light emitting operation corresponding to the first light emitting control signal. Then, in response to the light emitting device 11 performing the light emitting operation corresponding to the first light emitting control signal, the embedded controller 15 instructs an operating system to perform a system login operation.
In some embodiments, the light emitting device 11 may heat a driving integrated circuit on the integrated circuit board through the light emitting element. It should be noted that, the driving integrated circuit can control and provide the integrated circuit of the luminous element power.
For ease of understanding, please refer to a schematic diagram of the light emitting device 11 shown in fig. 2. As shown in fig. 2, the light emitting device 11 further includes a light emitting element 111 and an integrated circuit board 113, and the integrated circuit board 113 is electrically connected to the light emitting element 111. Specifically, the first light-emitting control signal is received by the integrated circuit board 113, and the light-emitting element 111 is controlled by the integrated circuit board 113 to perform the light-emitting operation corresponding to the luminance and the light-emitting time based on the first light-emitting control signal, so as to heat a driving integrated circuit on the integrated circuit board 113.
In some embodiments, the light emitting element 111 is disposed in a peripheral region of the driving integrated circuit. For example, the light emitting element 111 may be disposed in a shape of an elongated shape, an L-shape, a ring shape, or the like in a surrounding area of the driving integrated circuit.
In some embodiments, the display system DS further comprises a switching circuit and a CPU, wherein the switching circuit is used for switching between a heating mode in which the light emitting device performs a heating operation, a normal mode in which the CPU performs a power-on operation, a heating mode in which the CPU performs an over-frequency operation, and the like.
For ease of understanding, please refer to the display system DS shown in fig. 3. As shown in fig. 3, the display system DS further includes a central processing unit 35 and a switching circuit 33, wherein the switching circuit 33 is electrically connected to the central processing unit 35, the embedded controller 15 and the light emitting device 11.
In some embodiments, the switching circuit 33 receives a switching control signal from the embedded controller 15, wherein the switching control signal is used to indicate a heating mode or a normal mode. Then, in response to the switching control signal indicating the heating mode, the switching circuit 33 transmits the first light emission control signal to the light emitting device 11 to cause the light emitting device 11 to perform the light emitting operation corresponding to the first light emission control signal.
In some embodiments, the embedded controller 15 is electrically connected to the central processor 35, and in response to the switching control signal indicating the heating mode, an over-frequency control signal is transmitted from the embedded controller 15 to the central processor 35, so that the central processor 35 performs an over-frequency operation (e.g. increasing the processor frequency) corresponding to the over-frequency control signal, wherein the control signal includes an over-frequency setting.
For example, the embedded controller 15 may cause the CPU 35 to perform operations with Turbo Boost (Turbo Boost) by transmitting an over-frequency control signal from the platform environment control interface (Platform Environment Control Interface; PECI), and the over-frequency settings may correspond to over-frequency environment setting parameters of different over-frequency levels (e.g., clock frequency, current, temperature, power, number of operation cores of the CPU 35).
It should be noted that, since a large amount of heat energy is rapidly generated when the cpu 35 performs the over-frequency operation, the device temperature (e.g., the driving power) of the display system DS can be heated, so that the display system DS rapidly reaches the operating temperature capable of performing the power-on operation.
It should be understood that the present disclosure does not limit the number of operations simultaneously performed in the heating mode, and the display system DS may simultaneously perform the over-frequency operation by the cpu 35 and the light emitting operation by the light emitting device 11, so that the display system DS quickly reaches the operating temperature at which the power-on operation can be performed.
In some embodiments, the display system DS may also allocate the heating mode operation at different scales (e.g., execution time) or priorities (e.g., temperature threshold).
For example, the display system DS may set the execution time ratio of the light emitting operation to the over-frequency operation to be 2 to 1. For another example, the display system DS may be set to perform only the light emitting operation when the temperature is between minus 20 to minus 30 degrees. In addition, the display system DS may be set to perform the over-frequency operation and the light emitting operation at the same time when the temperature is lower than minus 30 degrees.
In some embodiments, when the display system DS is at the normal operating temperature, the switching circuit 33 can transmit the light-emitting control signal to the light-emitting device 11, so that the light-emitting device 11 performs the light-emitting operation with the preset brightness. Specifically, in response to the switching control signal indicating the normal mode, the switching circuit 33 transmits a predetermined control signal to the light emitting device 11 to cause the light emitting device 11 to perform the light emitting operation corresponding to a predetermined brightness.
As can be seen from the above description, the display system DS provided by the present disclosure can actively sense the ambient temperature information, and when the display system DS receives the power-on signal and the ambient temperature information is too low, the display system DS actively generates heat based on a plurality of different combinations to make the device reach the working temperature quickly. The display system DS provided by the disclosure can solve the problem that the display system cannot normally display when the low-temperature environment is started, so that the defect that the user experience is poor in the prior art is overcome.

In some embodiments, the embedded controller is electrically connected to the CPU, and the display method 400 further comprises the step of transmitting an over-frequency control signal to the CPU in response to the switching control signal indicating the heating mode, so that the CPU performs an over-frequency operation corresponding to the over-frequency control signal, wherein the control signal comprises an over-frequency setting.
In some embodiments, the display method 400 further includes the step of responding to the switching control signal to indicate the normal mode, the switching circuit transmitting a predetermined control signal to the light emitting device, so that the light emitting device performs the light emitting operation corresponding to a predetermined brightness.

In addition to the above steps, the second embodiment can also perform all the operations and steps of the display system DS described in the first embodiment, and have the same functions and achieve the same technical effects. Those skilled in the art can directly understand how to perform these operations and steps according to the first embodiment, which have the same functions and achieve the same technical effects, so that the description is omitted.
It should be noted that, in the present specification and claims, some terms (including light emission control signals, etc.) are preceded by "first" or "second", which are used to distinguish between different terms.
