Detailed ways

In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

It should be noted that the terms "first" and "second" in the specification and claims of the present disclosure and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein can be practiced in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

FIG. 1 is a flowchart of a display control method according to an embodiment of the present disclosure. Wherein, it should be noted that the display control method of this embodiment is executed by a display control device, which can be implemented by software and/or hardware, and that the display control device can be configured in an electronic device, and the electronic device can include a mobile Hardware devices with display screens such as terminals (such as mobile phones), tablet computers, smart TVs, smart wearable devices, and vehicle-mounted devices. Wherein, it can be understood that the display screen in this embodiment is a display screen using LTPO technology.

As shown in Fig. 1, the method includes the following steps S101 to S103.

Step 101, monitor display switching event.

In the embodiment of the present disclosure, the process of performing step 101 by the display control apparatus may be, for example, determining a current state of the display device; when the current state is an idle state, monitoring a display switching event.

Wherein, the display switching event includes at least one of the following events: a pixel-level dynamic contrast adjustment event, an automatic brightness adjustment event, and an automatic white balance adjustment event.

In some embodiments, the idle state of the display device may be, for example, that the user stays on a certain page for a long time, such as an e-book page, a web page, and the like.

Step 102, when a display switch event is detected, determine the current display refresh rate of the display screen.

Wherein, the current display refresh rate can be acquired in real time or at regular intervals. Taking the regular acquisition as an example, the current display refresh rate is monitored according to a preset period, wherein the embodiment of the present disclosure does not limit the preset period. It can be set according to actual needs.

In some embodiments, the display switch event can be a pixel-level dynamic contrast adjustment event, that is, the screen can automatically adjust the screen effect according to the intensity of the light, and can maintain the authenticity of the color and the overall beauty of the picture even in a shadow or lack of light environment It can take effect within 400ms from the beginning to the final achievement of the target effect.

In some embodiments, the display switching event can be an automatic white balance adjustment event, that is, the screen can automatically adjust the white balance according to the ambient light, so that the eyes will not be tired if they stare at the screen for a long time, and it may take 4 seconds to fully respond to the environment Changes in color temperature.

In some embodiments, the display switching event can be an automatic brightness adjustment event, that is, the screen can automatically adjust the brightness of the screen according to the light intensity of the surrounding environment, so that the eyes are more comfortable and the user experience is better.

In some embodiments, the automatic brightness adjustment event relies solely on the screen hardware for dimming, that is, the purpose of dimming is achieved by changing the characteristics of the screen circuit such as voltage, current, and pulse width modulation (PWM), as shown in Figure 2 It is a schematic diagram of hardware dimming, as shown in Figure 2, limited by the current hardware capabilities, the current hardware dimming basically supports up to 11bit (2048 levels) or 12bit (4096 levels).

In some embodiments, the automatic brightness adjustment event can realize 10,000-level dimming by combining software and screen hardware, that is, on the basis of each level of hardware brightness, the brightness can be fine-tuned by changing the display content, so that the software can achieve multi-level brightness. Figure 3 is a schematic diagram of 10,000-level dimming, as shown in Figure 3, for example, on the screen hardware brightness 3, the original screen displays a gray scale of 200, and the gray scale is changed to 180 by fine-tuning, then the hardware brightness 3 and the displayed content 180 gray scale The actual perception brightness is darker than the original hardware brightness 3 and the actual perception brightness of the display content 200 grayscale. Similarly, on this basis, change the grayscale to 190/195, etc., so that the software can insert multi-level brightness, and finally achieve The goal of 10,000-level dimming. The 3-level brightness dimming realized by software at a certain brightness level needs to dynamically adjust the display content to achieve the purpose of changing the brightness, and the refresh of the display content depends on the display switching refresh rate. When the display switching refresh rate is too low , unable to respond to the brightness adjustment in time, maybe when the screen is refreshed, the screen brightness adjustment has changed dozens of levels, for example, from 1 to 50, but what the user actually sees is only a direct change from 1 to 50, with a change of 48 levels in the middle will be lost, affecting the smoothness of the switching effect.

Step 103, when the current display refresh rate is lower than the set display switching refresh rate, adjust the current display refresh rate to the display switching refresh rate.

In some embodiments, the display switching refresh rate set by the display device can be 10HZ. Taking the display switching event as an automatic white balance adjustment event, and switching from state A to state B as an example, FIG. 4 is a schematic diagram of the effect of 10HZ gradient, as shown in FIG. As shown, it can be understood that when the display switching refresh rate is 10HZ, the display screen switches one frame every 100ms.

In some embodiments, the display switching refresh rate set by the display device may be 60HZ. Taking the display switching event as an automatic white balance adjustment event, and switching from state A to state B as an example, FIG. shown. It can be understood that when the display switching refresh rate is 60HZ, the display screen switches one frame every 16.6ms. Among them, when the display switching refresh rate is 10HZ, the intermediate gradient process is lost, making the actual effect appear to be jumping and not smooth. When the display switching refresh rate is above 60HZ, a smooth switching effect can be obtained, that is, smooth gradient, and each intermediate of the gradient The status can be displayed correctly.

In some embodiments, when the current display refresh rate is greater than or equal to the set display switching refresh rate, the display refresh rate adjustment process is stopped. At this time, the current display refresh rate can make the switching process of the display switching event smooth and ensure the display effect.

In some embodiments, before adjusting the current display refresh rate to the display switching refresh rate, the current display refresh rate is stored for subsequent adjustment.

The display control method of the embodiment of the present disclosure monitors the display switching event; when the display switching event is detected, the current display refresh rate of the display screen is determined; when the current display refresh rate is lower than the set display switching refresh rate, the current display refresh rate is adjusted. rate to display switching refresh rate. Therefore, by detecting the display switching event, the display refresh rate is adjusted in time to ensure the smoothness of automatic switching of display effects without affecting the system display refresh rate strategy.

For example, Fig. 6 is a flow chart of the display control method, as shown in Fig. 6, the display effect processing module: the user processes the display effect changes, and promptly notifies the monitoring module according to the state; the frame rate (display refresh rate) monitoring module: real-time monitoring The current system displays the refresh rate and receives notifications from the display effect processing module; timer module: used to provide timing for the frame rate monitoring module to call the display effect processing module to query whether the switching is completed; frame rate control module: used to receive the frame rate Monitor the request of the module and adjust the system display refresh rate in real time.

7 is a flowchart of a display control method according to another embodiment of the present disclosure. In this embodiment, after adjusting the current display refresh rate to the display switch refresh rate, the display refresh rate is adjusted in time by monitoring the execution status of the display switch event.

As shown in FIG. 7, the method may include the following steps S701 to S705.

Step 701, monitor display switching event.

Step 702, when a display switching event is detected, determine the current display refresh rate of the display screen;

Step 703, when the current display refresh rate is lower than the set display switching refresh rate, adjust the current display refresh rate to the display switching refresh rate.

Step 704, monitor the execution status of the display switching event.

In some embodiments, the execution status of the display switching event may be regularly checked according to a preset monitoring period, for example, where the embodiment of the present disclosure does not limit the preset monitoring period, which may be set according to actual needs.

Step 705, when the execution state is execution completed, adjust the current display refresh rate of the display screen to the stored display refresh rate.

In the embodiment of the present disclosure, the process of performing step 705 by the display control device may be, for example, determining the current state of the display screen when the execution state is execution completed; adjusting the current display refresh rate of the display screen when the current state is idle state to the stored display refresh rate.

In some embodiments, when the current state is a non-idle state, the display refresh rate adjustment process is stopped.

Wherein, it should be noted that, for details of step S701, step S702, and step S703, reference may be made to step S101, step S102, and step S103 in the embodiment shown in FIG. 1, and no detailed description will be given here.
