Abstract

The invention relates to a display control method and device of a display panel and a display device. The method comprises the following steps: acquiring gray scales and refresh rates of a current frame display picture and a next frame display picture to be displayed; according to the refresh rate of the current frame display picture and the refresh rate of the next frame display picture to be displayed, the brightness difference value of the current frame display picture and the next frame display picture to be displayed is obtained, and when the brightness difference value is larger than a first preset value and the gray scales of the current frame display picture and the next frame display picture to be displayed are the same, the current frame display picture and the next frame display picture to be displayed are displayed. And adding at least one frame of transition display picture to display before controlling the display panel to display the next frame of display picture to be displayed. When the refresh rate of the display picture is switched, the transition display picture is inserted, so that the problems of brightness difference and flicker caused when the refresh rate of the display picture is switched can be solved, and the display effect and the use comfort of a user are improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display control method, device and display device of a display panel. Background technique [0002] The display frequency conversion technology is a display technology that selects a suitable refresh rate according to the display content. The refresh rate of the display device is generally fixed at a certain frequency when the display device is working. For example, the most common refresh rate is 60 hertz (Hz). However, in some special display screens, the display device needs to be displayed at a higher or lower refresh rate. For example, when a game or video is played, a high refresh rate is used to improve the picture experience, and when a static picture or text application mode is used, a low refresh rate is used to improve the display experience. Reduce power consumption. The current market terminal mostly adopts variable refresh rate (Variable Refresh Rate, VR...
