Problems solved by technology

An excessively long blanking time will intensify the influence of the leakage of the display panel, and finally reduce the brightness of the panel as a whole.
However, if the display device is made to switch back and forth between high and low refresh rates in a short period of time according to a certain rule, the brightness difference between different refresh rates will cause serious flickering of the display screen.

Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0052] Please refer to figure 1 , figure 1 It is a schematic flow chart of the driving method of the display device provided by the embodiment of the present application. The driving method is used in a display device, which may be an organic light-emitting display or a liquid crystal display, and of course, may also be other common display devices. Wherein, the driving method includes the following steps:

Abstract

The invention provides a driving method of display equipment and the display equipment. The driving method comprises the following steps: inputting a plurality of prediction frames and detecting the refresh frequency of the display device based on the plurality of prediction frames to obtain a change rule of the refresh frequency; when the display device displays the target display frame, obtaining the current refresh frequency of the display device and the corresponding frame number information; predicting an expected time point when the display equipment switches the refresh frequency next time and an expected frequency value after switching according to the change rule, the current refresh frequency and the corresponding frame number information; and performing gray scale compensation on the display device according to the expected frequency value and the expected time point. According to the invention, flicker of a picture during refreshing frequency switching can be avoided.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a method for driving a display device and the display device. Background technique [0002] Generally, when a display device is working, its refresh rate is often fixed at a certain frequency, for example, the most common refresh rate is 60 Hz. However, under certain specific conditions, it is often required for the display device to display at a higher refresh rate. Free-Sync technology can enable the graphics card and accelerator processor to directly and dynamically control the refresh rate of the display device connected to it. [0003] For a display device equipped with Free-Sync technology, the charging time of each frame of the highest refresh rate and the lowest refresh rate is the same, the difference is that the blank time between the two frames is different. Because the frame duration corresponding to the low refresh rate is longer, the blank time will...
