Problems solved by technology

[0002] as attached figure 1 As shown, the display processing of the related technology is to send pictures to the display through the AP (Application Processor, application processor) for display. Because the complexity of the displayed pictures is different, there are special scenarios where the AP does not complete the rendering within a fixed time. That is, the new picture is not ready. In this case, the display usually repeatedly refreshes the data of the previous frame for display, and waits for the new data to arrive before updating the display. However, this will cause frame loss during the display process. This can cause visual tearing or delay issues

Abstract

The invention relates to a display brightness control method and device and electronic equipment, and the method comprises the steps: reducing the refresh rate of a self-luminous display to prolong the display duration of an (N + 1) th frame of image when the (N + 1) th frame of image is displayed for a preset display duration and an (N + 2) th frame of image is not received, N being a positive integer; according to the refresh rate, the duty ratio of an emission signal is adjusted so as to control the brightness of the self-luminous display, and the emission signal is used for controlling the light emitting period of the self-luminous display. According to the embodiment of the invention, on one hand, the problems of frame loss, high delay, tearing of image display and the like can be avoided, and the brightness compensation can be realized by dynamically adjusting the emission signal of the display according to the refresh rate, so that the display brightness is consistent when the frame frequency is changed, and the problem of screen flicker caused by an electric leakage phenomenon of a storage capacitor of the display is avoided.

Description

technical field [0001] The present disclosure relates to the field of display technologies, and in particular, to a display brightness control method and device, and electronic equipment. Background technique [0002] as attached figure 1 As shown, the display processing of the related technology is to send pictures to the display through the AP (Application Processor, application processor) for display. Because the complexity of the displayed pictures is different, there are special scenarios where the AP does not complete the rendering within a fixed time. That is, the new picture is not ready. In this case, the display usually repeatedly refreshes the data of the previous frame for display, and waits for the new data to arrive before updating the display. However, this will cause frame loss during the display process. This can cause visual tearing or delay issues. Contents of the invention [0003] According to an aspect of the present disclosure, a display brightness...
