Description

Technical Field

[0001] This application relates to the field of display technology, specifically to a display device and a control method for the display device. Background Technology

[0002] When the display screen displays a static image, it can enter a power-saving mode. In this mode, the contents of the display device's system memory are copied to the display panel's memory. The display panel then reads display data directly from its own memory to refresh the image, eliminating the need to load data from system memory and thus reducing power consumption. When the display switches from static to dynamic, the display panel must exit power-saving mode. Because the display panel randomly enters and exits power-saving mode, the polarity of the positive and negative frame data may become asymmetrical. This can cause the voltage across the liquid crystal to fail to cancel each other out, resulting in residual charge at the liquid crystal terminals. Over time, this charge can accumulate and cause liquid crystal polarization, leading to screen flicker and affecting display quality. Summary of the Invention

[0022] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. The described technical solutions are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.

[0023] Furthermore, in the embodiments of this application, "multiple" refers to two or more. The terms "first" and "second," etc., in the embodiments of this application are used to distinguish different technical features and do not indicate any order, quantity, or importance.

[0024] The various embodiments provided in this application are similar, and features in different embodiments can be combined with each other.

[0025] The order in which the following embodiments are described is not intended to limit the preferred order of the embodiments.

[0026] Please see Figure 1 , Figure 1 This is a display device provided in an embodiment of this application. For example... Figure 1 As shown, the display device includes a motherboard 100 and a display panel 200 connected to the motherboard 100. The display panel 200 includes a timing controller (TCON) 300.

[0027] The timing controller 300 is configured to control the display panel 200 to enter power-saving mode.

[0028] The motherboard 100 is configured to: detect the number of consecutive frames in power-saving mode of the display panel 200 in response to the display screen switching from static to dynamic; and send a first exit command to the timing controller 300 in response to the number of consecutive frames being even.

[0029] The timing controller 300 is also configured to control the display panel 200 to exit power-saving mode in response to the first exit command.

[0030] This application does not limit the specific power-saving mode in its embodiments. In some embodiments, the power-saving mode includes a Panel Self Refresh (PSR) mode. In PSR mode, the content in the system memory is copied to the display panel's memory, allowing the display panel to directly read display data from its own memory to refresh the display screen without loading display data from the system memory. Of course, the power-saving mode can also include other modes, such as a Low Refresh Rate (LRR) mode and Content Adaptive Brightness Control (CABC) mode. In LRR mode, the display panel reduces its refresh rate to save power; in CABC mode, the backlight brightness of the display panel is dynamically adjusted by sensing the brightness of the displayed image.

[0031] When the displayed screen is static, such as when the display screen switches from dynamic to static, the timing controller 300 can control the display panel 200 to enter a power-saving mode. In this embodiment, the motherboard 100 can continuously monitor the displayed screen. When the motherboard 100 detects that the displayed screen is static, the motherboard 100 can send an entry command to the timing controller 300, thereby the timing controller 300 controls the display panel 200 to enter the power-saving mode according to the entry command. It should be understood that a static displayed screen means that the content of the displayed screen has not changed, while a dynamic displayed screen means that the content of the displayed screen has changed.

[0032] The motherboard 100 continuously monitors the display screen. In response to the display screen switching from static to dynamic, the motherboard 100 detects the number of consecutive frames during which the display panel 200 is in power-saving mode. In some embodiments, the motherboard 100 determines the number of consecutive frames during which the display panel 200 is in power-saving mode based on a first moment, a second moment, and the duration of a single frame of the display screen. The first moment can refer to the moment when the motherboard 100 detects the display screen switching from dynamic to static, and the second moment can refer to the moment when the motherboard 100 detects the display screen switching from static to dynamic. Between the first moment and the second moment, the display screen is static. The motherboard 100 can determine the number of consecutive frames during which the display panel 200 is in power-saving mode based on the duration between the first moment and the second moment, and the duration of a single frame of the display screen. For example, the number of consecutive frames = (second moment - first moment) / duration of a single frame.

[0033] Because the positive and negative frame voltages of the data output cannot cancel each other out when the power-saving mode lasts for an odd number of frames, this accumulation over a long period can cause the liquid crystal to polarize, leading to flickering. Therefore, when the motherboard 100 detects that the display screen is switching from static to dynamic, it does not immediately control the display panel 200 to exit the power-saving mode. Instead, it determines whether the number of consecutive frames the display panel 200 has been in power-saving mode is even, and controls the display panel 200 to exit the power-saving mode based on the determination result.

[0034] If the number of consecutive frames in power-saving mode is even, the display panel 200 can exit power-saving mode without leaving any charge residue. In response to the number of consecutive frames in power-saving mode being even, the motherboard 100 sends a first exit command to the timing controller 300, and the timing controller 300 responds to the first exit command by controlling the display panel 200 to exit power-saving mode.

[0035] If the number of consecutive frames in power-saving mode of the display panel 200 is odd, the display panel 200 cannot exit power-saving mode at that time, because exiting power-saving mode at that time would result in residual charge. In some embodiments, in response to the number of consecutive frames in power-saving mode of the display panel 200 being odd, the motherboard 100 can continuously detect the number of consecutive frames in power-saving mode of the display panel 200, and in response to the number of consecutive frames in power-saving mode of the display panel 200 being even, the motherboard 100 sends a first exit command to the timing controller 300. In other embodiments, the motherboard 100 is further configured to send a first exit command to the timing controller 300 after a first number of frames in response to the number of consecutive frames in power-saving mode of the display panel 200 being odd. In other embodiments, the motherboard 100 is further configured to send a second exit command to the timing controller 300 in response to an odd number of consecutive frames in which the display panel 200 is in power-saving mode; the timing controller 300 is further configured to control the display panel 200 to exit power-saving mode after a first number of frames in response to the second exit command.

[0036] The first frame count is odd. This application embodiment does not limit the specific number of frames for the first frame; for example, it can be 1 frame, 3 frames, or 5 frames, etc. In practical applications, the first frame count can be flexibly set according to requirements. If the number of consecutive frames the display panel 200 is in power-saving mode is odd, the motherboard 100 can wait for the first frame count before sending a first exit command to the timing controller 300. The timing controller 300 responds to the first exit command and controls the display panel 200 to exit power-saving mode. Alternatively, the motherboard 100 can send a second exit command to the timing controller 300. The timing controller 300 responds to the second exit command, waits for the first frame count, and then controls the display panel 200 to exit power-saving mode. This application embodiment ensures that when the display panel 200 exits power-saving mode, the number of consecutive frames in power-saving mode is even, thereby avoiding residual charge.

[0037] The first exit command and the second exit command are different. In response to the first exit command, the timing controller 300 immediately controls the display panel 200 to exit the power-saving mode; while in response to the second exit command, the timing controller 300 controls the display panel 200 to exit the power-saving mode after the first frame. This embodiment does not limit the specific setting of the first and second exit commands; in practical applications, they can be flexibly set according to requirements. For example, the first exit command can be 00 and the second exit command can be 01; or, the first exit command can be 01 and the second exit command can be 00.

[0038] In summary, the display device provided in this application embodiment includes a motherboard and a display panel connected to the motherboard, the display panel including a timing controller. The timing controller is configured to: control the display panel to enter a power-saving mode; the motherboard is configured to: detect the number of consecutive frames the display panel is in power-saving mode in response to a static to dynamic display screen switching, and send a first exit command to the timing controller in response to an even number of consecutive frames; the timing controller is further configured to control the display panel to exit the power-saving mode in response to the first exit command. In this application embodiment, after the display panel enters power-saving mode, if a static to dynamic display screen switch is detected, the display panel is controlled to exit power-saving mode when the number of consecutive frames in power-saving mode is even, ensuring that the polarities of positive and negative frames cancel each other out, avoiding residual charge at both ends of the liquid crystal, thereby preventing screen flickering due to liquid crystal polarization caused by residual charge, improving display effect, and extending the lifespan of the display panel.

[0039] In some embodiments, the motherboard 100 is further configured to: in response to the display screen switching from dynamic to static, send a first entry command to the timing controller 300 after a second frame number; the timing controller 300 is further configured to: in response to the first entry command, control the display panel 200 to enter a power-saving mode.

[0040] In other embodiments, the motherboard 100 is further configured to send a second entry command to the timing controller 300 in response to the display screen switching from dynamic to static; the timing controller 300 is further configured to control the display panel 200 to enter a power-saving mode after a second number of frames in response to the second entry command.

[0041] The motherboard 100 continuously monitors the display screen. If it detects a switch from dynamic to static display, it controls the display panel 200 to enter power-saving mode. In this embodiment, when the motherboard 100 detects a switch from dynamic to static display, it does not immediately control the display panel 200 to enter power-saving mode. Instead, it delays the switch by a second frame number before entering power-saving mode. This embodiment does not limit the specific number of frames for the second frame; it can be any number of frames and can be flexibly set according to requirements in practical applications. For example, the second frame number can be 1 frame, 2 frames, 3 frames, or 4 frames. In some embodiments, the second frame number is negatively correlated with the display panel's anti-polarization capability; the stronger the anti-polarization capability, the smaller the second frame number; conversely, the weaker the anti-polarization capability, the larger the second frame number. Of course, the second frame number can also be related to the design characteristics of the display panel, and in practical applications, it can be preset based on the display panel's testing results.

[0042] If the displayed image switches from dynamic to static, the motherboard 100 can wait for the second frame count before sending a first entry command to the timing controller 300. The timing controller 300, in response to the first entry command, controls the display panel 200 to enter power-saving mode. Alternatively, the motherboard 100 can send a second entry command to the timing controller 300, and the timing controller 300, in response to the second entry command, waits for the second frame count before controlling the display panel 200 to enter power-saving mode. This embodiment of the application delays the time it takes for the display panel 200 to enter power-saving mode, reducing the frequency of static electricity accumulation. Even if screen flickering may still occur due to residual charge, the time delay reduces the probability of flickering during terminal applications.

[0043] The first entry command and the second entry command are different. In response to the first entry command, the timing controller 300 immediately controls the display panel 200 to enter power-saving mode; while in response to the second entry command, the timing controller 300 controls the display panel 200 to enter power-saving mode after a second number of frames. This embodiment does not limit the specific setting of the first and second entry commands; in practical applications, they can be flexibly set according to requirements. For example, the first entry command can be 11 and the second entry command can be 10; or, the first entry command can be 10 and the second entry command can be 11.

[0044] For example, the display panel 200 enters power-saving mode at frame 1 and exits power-saving mode after 5 frames; it enters power-saving mode at frame 8 and exits power-saving mode after 6 frames; it enters power-saving mode at frame 16 and exits power-saving mode after 3 frames; within 18 frames, the display panel enters and exits power-saving mode 3 times. If, based on the technical solution provided in this application embodiment, the display panel 200 enters power-saving mode after a second frame delay each time, such as a 6-frame delay, then the display panel 200 enters power-saving mode at frame 7 and exits power-saving mode after 5 frames; it enters power-saving mode at frame 14 and exits power-saving mode after 6 frames; and it enters power-saving mode at frame 22 and exits power-saving mode after 3 frames. Within the same 18-frame timeframe, the display panel only enters power-saving mode twice, reducing the frequency of static electricity accumulation.

[0045] In summary, the display device provided in this application includes a motherboard and a display panel connected to the motherboard, the display panel including a timing controller. Specifically, when the motherboard detects that the display screen is switching from dynamic to static, it controls the display panel to enter a power-saving mode after a certain frame delay. This application delays the time it takes for the display panel to enter the power-saving mode, reducing the frequency of static electricity accumulation. Even though screen flickering may still occur due to residual charge, the time delay reduces the probability of flickering during terminal applications, improving display performance and extending the lifespan of the display panel.

[0046] For example, such as Figure 2 As shown, when playing audio, only the progress bar 210 changes once per second on the display panel 200. Within milliseconds, the display is static with no refresh. Therefore, when the motherboard detects that the display is static, it delays for 8 frames to control the display panel 200 to enter power-saving mode; and when the progress bar 210 changes every second, it controls the display panel 200 to exit power-saving mode. After multiple experiments, as shown... Figure 3 As shown, when the display panel 200 directly enters power-saving mode, screen flickering begins after the display panel 200 plays audio continuously for 1 to 2 hours; however, when the display panel 200 enters power-saving mode with an 8-frame delay, no screen flickering occurs even after 6 hours of continuous playback. Therefore, the embodiments of this application improve the display effect.

[0047] It should be understood that the technical solutions provided in the embodiments of this application can be used individually or in combination. For example, the display panel can be controlled to exit power saving mode only when the number of consecutive frames in power saving mode is even; or the display panel can be controlled to enter power saving mode only after a certain delay when entering power saving mode; or the display panel can be controlled to enter power saving mode after a certain delay when entering power saving mode, and when the display panel exits power saving mode, the display panel can be controlled to exit power saving mode only when the number of consecutive frames in power saving mode is even.
