[0090] Figure 3 A schematic diagram of the interaction of various related modules in the point screen process provided by an embodiment of the present application is shown in FIG. 1. Figure 3As shown, the specific control procedure for the current display device to light up the backlight panel at the power-on time is as follows: first, the SOC completes the initialization of the display screen, controls the power-on of the supply voltage (Volt Current Condenser, VCC), that is, the power-on of the TCON, the TCON starts to execute its own program, and starts to establish a handshake with the SOC through the VB1 (that is, the V-by-One signal) signal, and the TCON completes the initialization; then the SOC controls the output clock data recovery lock signal (Clock Data Recovery Lock Signal, LOCKN) to change from high level to low level, indicating that the SOC and the TCON have successfully established a handshake, and the TCON converts the VB1 signal into a low-voltage differential signaling (Low-Voltage Differential Signaling, LVDS) signal and outputs it to the display screen; the SOC powers on the power-on port (that is, the backlight pin) of the backlight control chip, at which time the backlight unit (Backlight Unit, BLU) and other backlight control chips are powered, the BLU executes its own program, receives the backlight control signal from the SOC, lights up the backlight lamp strip in the display screen, and completes the lighting of the backlight panel. In the specific control procedure for the display device to light up the backlight panel at the power-on time, the BLU is used to process the backlight control, specifically, the BLU is used for regional backlight adjustment in local backlight processing, and after the BLU executes its own program, the lighting of the backlight panel is completed. Among them, after the SOC powers on the power-on port of the BLU, the BLU starts to execute its own program, and the BLU needs a certain time to execute its own program. According to the screen-on timing specified in the display screen specification, the step of executing the program of the BLU is redundant relative to the screen-on timing, and therefore, in the control procedure for lighting the backlight panel described above, after the BLU executes its own program, the lighting of the backlight panel is completed, which results in a long power-on time.

[0091] Based on the above problems, the present application provides a display device, a screen-on method and device, which can shorten the time for lighting the backlight panel at the power-on time of the display device by adjusting the power-on time of the backlight control component (such as the BLU), thereby shortening the power-on time and improving the user experience.

[0092] In the following application embodiments, the backlight control component is taken as the BLU as an example, and detailed embodiments are used to illustrate how the present application performs screen-on. It should be noted that the backlight control component of the present application is not limited to the BLU.

[0093] Figure 4 The flowchart of the screen-on method provided by an embodiment of the present application is applied to a display device. As shown in Figure 4 The processor in the display device is configured to perform the following steps:

[0094] In S401, after the display device is started, the backlight control component is powered on in advance based on the power-on time of the backlight control component when the display device is started for the first time and the initialization duration of the backlight control component.

[0095] The initialization duration is the duration from the power-on time of the backlight control component to the completion time of initialization when the display device is started for the first time.

[0096] In the embodiment of the present application, the backlight control component is BLU. When the display device is started for the first time, the power-on time of the BLU can be determined based on the current control process of lighting the backlight panel when the display device is started. It can be understood that the power-on of the BLU refers to the power-on of the power-on port of the BLU controlled by the processor, such as a general purpose input / output (GPIO) pin. After the BLU is powered on, the BLU executes its own program, that is, performs initialization, receives the backlight control signal from the SOC, and completes the lighting of the backlight panel. The completion time of the initialization of the BLU can be determined. After the power-on time of the BLU and the completion time of the initialization of the BLU are obtained, the initialization duration of the BLU can be determined as the duration from the power-on time of the BLU to the completion time of the initialization of the BLU. After the initialization duration of the BLU is determined, the BLU can be powered on in advance based on the power-on time of the BLU when the display device is started for the first time and the initialization duration of the BLU after the display device is started. For details of how to power on the backlight control component in advance based on the power-on time of the backlight control component when the display device is started for the first time and the initialization duration of the backlight control component, reference can be made to the subsequent embodiments, which will not be described here.

[0097] In S402, the backlight control component is initialized.

[0098] In this step, the backlight control component is BLU. After the processor powers on the BLU in advance based on the power-on time of the BLU when the display device is started for the first time and the initialization duration of the BLU, the BLU executes its own program and completes initialization.

[0099] In S403, the backlight panel of the display device is lit.

[0100] The backlight control component is BLU. After the BLU executes its own program and completes initialization, the BLU receives the backlight control signal from the processor, completes the backlight control of the display screen, and lights the backlight panel of the display device.

[0101] The point screen method provided in the embodiments of the present application can power on the backlight control component in advance, initialize the backlight control component, and light up the backlight panel of the display device based on the power-on time of the backlight control component when the display device is started for the first time and the initialization duration of the backlight control component after the start-up. Since the embodiments of the present application can power on the backlight control component in advance according to the initialization duration of the backlight control component under the premise of meeting the point screen timing specified in the display screen specification, the time consumption for lighting up the backlight panel when the display device is started can be shortened, and thus the start-up duration can be shortened, and the user experience can be improved.

[0102] The point screen method provided in the embodiments of the present application will be described in detail in combination with specific steps.

[0103] Figure 5 The flowchart of the point screen method provided in another embodiment of the present application is shown in FIG. 5. Figure 5 As shown in FIG. 5, the processor in the display device is configured to perform the following steps.

[0104] In S501, after the start-up, the backlight control component is powered on based on the power-on time of the backlight control component when the display device is started for the first time and the initialization duration of the backlight control component.

[0105] In the embodiments of the present application, the backlight control component is BLU, and based on the current control process of lighting up the backlight panel when the display device is started, the power-on time of the BLU and the time when the BLU completes initialization can be determined, and thus the initialization duration of the BLU can be determined. After the start-up of the display device, the power-on time of the BLU is advanced by the initialization duration of the BLU based on the power-on time of the BLU when the display device is started for the first time, that is, the BLU is powered on at a time point before the power-on time of the BLU when the display device is started for the first time, and the duration from the time point to the power-on time of the BLU when the display device is started for the first time is the initialization duration of the BLU.

[0106] In S502, the backlight control component is initialized.

[0107] The specific implementation process of this step can be referred to the related description of S402, which will not be described here.

[0108] In S503, the backlight panel of the display device is lighted up.

[0109] The specific implementation process of this step can be referred to the related description of S403, which will not be described here.

[0110] The point screen method provided by the embodiments of the present application can power on the backlight control component in advance based on the power-on time of the backlight control component when the display device is started for the first time, and initialize the backlight control component, thereby lighting the backlight panel of the display device. Since the embodiments of the present application can power on the backlight control component in advance according to the initialization time of the backlight control component under the premise of meeting the point screen timing specified in the display screen specification, the time consumption for lighting the backlight panel when the display device is started can be shortened, and the start-up time is shortened, thereby improving the user experience.

[0111] Figure 6 The point screen timing provided by an embodiment of the present application is shown in the figure. Figure 6 As shown in the figure, the power supply voltage VCC, the LOCKN, the VB1 signal, the backlight on / off control signal, timing 1 and timing 2 of the display device point screen circuit are shown. The timing 1 is the timing for lighting the backlight panel when the display device is started at present, and the timing 2 is the timing for lighting the backlight panel when the display device is started provided by the present application. Specifically, with reference to the timing 1, after the SOC (i.e. the processor) initialization is completed, the VCC is powered on, i.e. the TCON is powered on, and the TCON starts to execute its own program and starts to establish a handshake with the SOC through the VB1 signal. The time length from the TCON power-on time to the time when the TCON and the SOC start to establish a handshake through the VB1 signal is t1_1 in the timing 1. Figure 6 After the SOC and the TCON successfully handshake, the SOC controls the LOCKN to change from a high-level signal to a low-level signal. The time length from the time when the TCON and the SOC start to establish a handshake through the VB1 signal to the time when the SOC powers on the power-on port of the BLU through the backlight power-on control signal is t1_2 in the timing 1. Figure 6 After the SOC powers on the power-on port of the BLU through the backlight power-on control signal, the BLU is powered on, and the BLU executes its own program to complete the initialization of the BLU within the t1_3 time length. The BLU receives the backlight control signal from the SOC and completes the lighting of the backlight panel. As can be seen from the timing 1, the total time consumption t1 for lighting the backlight panel is t1_1+t1_2+t1_3.

[0112] Specifically, with reference to the timing 2, after the SOC initialization is completed, the VCC is powered on, i.e. the TCON is powered on, and the TCON starts to execute its own program and starts to establish a handshake with the SOC through the VB1 signal. The time length from the TCON power-on time to the time when the TCON and the SOC start to establish a handshake through the VB1 signal is t1_1 in the timing 2. Figure 6t2_1, it can be understood that t2_1 is equal to t1_1, and each step performed in the time range of t2_1 is the same as each step performed in the time range of t1_1; after the SOC and the TCON successfully handshake, the SOC controls the LOCKN to change from a high-level signal to a low-level signal; t2_2 is equal to t1_2, and in the time range of t2_2, in addition to performing the same steps as those performed in the time range of t1_2, at the start time of t2_3 included in t2_2, the SOC powers on the power-on port of the BLU through a backlight power-on control signal (not shown in the SOC in FIG. 2) (the corresponding backlight power-on control signal is not shown in the SOC in FIG. 2), the BLU is powered on Figure 6 , the BLU performs its own program, and completes the initialization of the BLU in the time range of t2_3. The BLU receives the backlight control signal from the SOC and completes the lighting of the backlight panel. It can be understood that t2_3 is the initialization time of the BLU. As can be seen from timing 2, the total time t2 of lighting the backlight panel is t2_1+t2_2, and the initialization of the BLU is performed synchronously in the time range of t2_3 included in t2_2. t2 is less than t1, so the time consumption of lighting the backlight panel when the display device is started is shortened, and the requirement of the screen timing specified in the display screen specification is met.

[0113] Figure 7 A flowchart for determining the initialization time of the backlight control component is provided for an embodiment of the present application. As shown in FIG. 8, the processor in the display device is configured to perform the following steps: Figure 7

[0114] In S701, after the display device is started for the first time, the backlight control component outputs a first detection signal at the power-on time.

[0115] In the embodiment of the present application, the backlight control component is BLU, and the first detection signal is, for example, a high-level signal output by the BLU through a GPIO pin. After the display device is started for the first time, the processor controls the BLU to output a high-level signal at the power-on time, and starts a timer according to the high-level signal to record the initialization time of the BLU.

[0116] In S702, the backlight control component is initialized.

[0117] The specific implementation process of this step can be referred to the related description of S402, which will not be described here.

[0118] In S703, the backlight control component outputs a second detection signal at the completion initialization time.

[0119] ​In this step, the second detection signal is exemplarily a low-level signal output by the BLU through the GPIO pin, and the processor controls the BLU to output the low-level signal at the initialization completion time point. The processor stops the timer according to the low-level signal.

[0120] In S704, the initialization duration is determined according to the first detection signal and the second detection signal.

[0121] Exemplarily, the processor starts the timer at the BLU power-on time point when the high-level signal is output, and stops the timer at the BLU initialization completion time point when the low-level signal is output. Therefore, the initialization duration of the BLU can be determined according to the duration counted by the timer.

[0122] In S705, the initialization duration is stored in the eMMC, so as to be obtained from the eMMC at the subsequent boot-up.

[0123] In this step, exemplarily, after the initialization duration of the BLU is obtained, the initialization duration of the BLU can be stored in the eMMC. After the display device is booted up for the subsequent time (i.e., the non-first boot-up), the processor can directly obtain the initialization duration of the BLU from the eMMC, and then power on the BLU in advance according to the initialization duration of the BLU.

[0124] The method for determining the initialization duration of the backlight control component provided by the embodiment of the application can accurately obtain the initialization duration of the backlight control component, so as to power on the backlight control component in advance according to the obtained initialization duration of the backlight control component, thereby shortening the time for lighting the backlight panel at the boot-up of the display device.

[0125] The following is an apparatus embodiment of the application, which can be used to execute the method embodiments of the application. For details not disclosed in the apparatus embodiments of the application, refer to the method embodiments of the application.

[0133] Optionally, after determining the initialization duration, the determination module 804 can store the initialization duration in an eMMC, so as to obtain the initialization duration from the eMMC when the display device is started up subsequently.
