[0034] In order for those skilled 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 described clearly and completely below with reference to the drawings.

[0035] It should be noted that the terms "first", "second", and the like in the specification and claims of the present disclosure and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The implementation described in the following exemplary embodiments does not represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0036] Figure 1 A flow chart of a display control method according to an embodiment of the present disclosure. It should be noted that the display control method of the present embodiment is executed by a display control device, which can be implemented by software and / or hardware, and can be configured in an electronic device, which can include a mobile terminal (such as a mobile phone), a tablet computer, a smart television, a smart wearable device, a vehicle-mounted device, and other hardware devices with a display screen. It should be understood that the display screen in the present embodiment is a display screen using LTPO technology.

[0037] As shown in FIG. 1, the method includes the following steps: Figure 1

[0038] Step 101, monitoring a display switching event.

[0039] In the embodiments of the present disclosure, the process of step 101 performed by the display control device may, for example, be determining the current state of the display device; and when the current state is an idle state, monitoring a display switching event.

[0040] ​The display switching event includes at least one of a pixel-level dynamic contrast adjustment event, an automatic brightness adjustment event, and a white balance automatic adjustment event.

[0041] In some embodiments, the idle state of the display device can be, for example, that the user stays on a certain page, such as an e-book page, a webpage, and the like, for a long time.

[0042] In step 102, when the display switching event is monitored, the current display refresh rate of the display screen is determined.

[0043] The current display refresh rate can be obtained in real time or at a regular time. For example, the current display refresh rate is monitored according to a preset period, and the preset period is not limited in the embodiments of the present disclosure and can be set according to actual needs.

[0044] In some embodiments, in one example, the display switching event can be a pixel-level dynamic contrast adjustment event, that is, the screen can automatically adjust the screen effect according to the light intensity, and the color authenticity and the overall beauty of the picture can be maintained in the shadow or the environment lacking light within 400 ms from the start to the final target effect.

[0045] In another example, the display switching event can be a white balance automatic adjustment event, that is, the screen can automatically adjust the white balance according to the ambient light, so that the eyes are not easily tired when staring at the screen for a long time, and it can take 4 seconds to completely respond to the change of the ambient color temperature.

[0046] In another example, 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 use experience is better.

[0047] In some embodiments, the automatic brightness adjustment event simply relies on the screen hardware to adjust the light, that is, by changing the voltage, current, pulse width modulation (PWM) and other characteristics of the screen circuit to achieve the purpose of adjusting the light, Figure 2 The schematic diagram of hardware dimming is shown in FIG. 1. Figure 2 As limited by the current hardware capability, the current hardware dimming basically supports at most 11 bits (2048 levels) or 12 bits (4096 levels).

[0048] In some embodiments, the automatic brightness adjustment event can achieve ten-thousand-level dimming by combining software and screen hardware, that is, on the basis of each level of hardware brightness, the brightness is fine-tuned by changing the display content to achieve the purpose of multi-level brightness realized by software. Figure 3 The schematic diagram of ten-thousand-level dimming is shown in FIG. 2. Figure 3As shown, for example, on screen hardware brightness 3, the original screen display gray scale is 200, which is changed to 180 by fine-tuning the gray scale, and the actual perceived brightness of hardware brightness 3 and display content 180 gray scale is darker than the actual perceived brightness of original hardware brightness 3 and display content 200 gray scale. Similarly, on this basis, the gray scale is changed to 190 / 195, etc., to achieve software insertion of multiple levels of brightness, and ultimately achieve the goal of ten-thousand-level dimming. Three-level brightness dimming achieved by software at a certain brightness level requires dynamic adjustment of display content to change 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, the brightness adjustment cannot be responded in time, and the screen brightness may have changed by dozens of levels during screen refresh, for example, from 1 to 50. However, the user actually sees only the direct change from 1 to 50, and the change of the intermediate 48 levels is lost, affecting the smoothness of the switching effect.

[0049] Step 103: When the current display refresh rate is less than the set display switching refresh rate, the current display refresh rate is adjusted to the display switching refresh rate.

[0050] In some embodiments, the display device sets the display switching refresh rate to 10 HZ, and the display switching event is a white balance automatic adjustment event. Taking the switching from state A to state B as an example, Figure 4 The effect gradual change diagram for 10 HZ is as shown in Figure 4 It can be understood that when the display switching refresh rate is 10 HZ, the display screen switches a frame every 100 ms.

[0051] In some embodiments, the display device sets the display switching refresh rate to 60 HZ, and the display switching event is a white balance automatic adjustment event. Taking the switching from state A to state B as an example, Figure 5 The effect gradual change diagram for 60 HZ is as shown in Figure 5 It can be understood that when the display switching refresh rate is 60 HZ, the display screen switches a frame every 16.6 ms. When the display switching refresh rate is 10 HZ, the intermediate gradual change process is lost, making the actual effect jump and not smooth. When the display switching refresh rate is higher than 60 HZ, a smooth switching effect, i.e., smooth gradual change, can be obtained, and each intermediate state of the gradual change can be correctly displayed.

[0052] 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.

[0053] 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.

[0054] The display control method of the embodiment of the present disclosure monitors a display switching event, determines a current display refresh rate of a display screen when the display switching event is monitored, and adjusts the current display refresh rate to a display switching refresh rate when the current display refresh rate is less than the set display switching refresh rate. Thus, by detecting the display switching event and timely adjusting the display refresh rate, the display effect automatic switching smoothness is ensured without affecting the system display refresh rate strategy.

[0055] For example, Figure 6 The flowchart of the display control method is shown in FIG. 7, which includes a display effect processing module, a frame rate (display refresh rate) monitoring module, a timer module, and a frame rate control module. Figure 6 The display effect processing module processes the display effect change and timely notifies the monitoring module according to the state. The frame rate monitoring module monitors the current system display refresh rate in real time and receives the notification from the display effect processing module. The timer module is used to provide the frame rate monitoring module with a timely call to the display effect processing module to query whether the switching is completed. The frame rate control module is used to receive the request of the frame rate monitoring module and adjust the system display refresh rate in real time.

[0056] Figure 7 The flowchart of the display control method of another embodiment of the present disclosure includes timely adjusting the display refresh rate by monitoring the execution state of the display switching event after adjusting the current display refresh rate to the display switching refresh rate.

[0057] As shown in FIG. 8, the method can include the following steps: Figure 7

[0058] Step 701, monitoring a display switching event.

[0059] Step 702, determining a current display refresh rate of a display screen when the display switching event is monitored.

[0060] Step 703, adjusting the current display refresh rate to a display switching refresh rate when the current display refresh rate is less than the set display switching refresh rate.

[0061] Step 704, monitoring an execution state of the display switching event.

[0062] In some embodiments, the execution state of the display switching event can be checked according to a preset monitoring period, for example. The preset monitoring period is not limited in the embodiments of the present disclosure and can be set according to actual needs.

[0063] Step 705, adjusting the current display refresh rate of the display screen to the stored display refresh rate when the execution state is execution completed.

[0064] ​In the embodiments of the present disclosure, the display control apparatus can perform the process of step 705, for example, when the execution state is execution completed, determining the current state of the display screen; when the current state is an idle state, adjusting the current display refresh rate of the display screen to the stored display refresh rate.

[0065] In some embodiments, when the current state is a non-idle state, the display refresh rate adjustment process is stopped.

[0066] It should be noted that the details of steps 701, 702 and 703 can refer to steps 101, 102 and 103 in the embodiments shown in Figure 1 The details of steps 101, 102 and 103 in the embodiments shown in

[0067] The display control method of the embodiments of the present disclosure can monitor the execution state of the display switching event; when the execution state is execution completed, adjust the current display refresh rate of the display screen to the stored display refresh rate. Thus, by detecting the display switching event, the display refresh rate is adjusted in time, which ensures the smoothness of automatic switching of display effect without affecting the system display refresh rate strategy.
