Problems solved by technology

Since the charging time of the pixel capacitance of each row corresponding to the low refresh rate is the same as the charging time of the pixel capacitor of each row corresponding to the high refresh rate, therefore, the low refresh rate maintains the grayscale brightness in the time period of the vertical blank line, and the pixel capacitor voltage The retention time is bound to be longer than the high refresh rate, and the longer the retention time, the more leakage, the gray-scale voltage changes, resulting in gray-scale brightness changes

Abstract

The invention discloses a refresh rate switching display method and device, computer equipment and a medium. One specific embodiment of the method comprises the following steps: acquiring gray-scale reference voltage of each gray scale; calculating gray scale voltage variation of each gray scale corresponding to different refresh rates; compensating the gray-scale reference voltage of the corresponding gray scale according to the gray-scale voltage variation of each gray scale corresponding to different refresh rates to obtain gray-scale compensation voltage of each gray scale corresponding todifferent refresh rates; and when the refresh rates in the same gray scale are switched, performing display driving by utilizing the gray scale compensation voltage of the current refresh rate corresponding to the gray scale. According to the embodiment, the display drive can be accurately and efficiently controlled, the image flicker phenomenon occurring when the refresh rate in the same gray scale is switched can be effectively eliminated, and then the display effect and the user experience can be improved.

Description

technical field [0001] The invention relates to the field of display technology. More specifically, it relates to a refresh rate switching display method and device, computer equipment and media. Background technique [0002] At present, many display devices have a display frequency conversion function. For example, with the development of TFT-LCD display devices towards games, many TFT-LCD display devices have supported the Freesync (display frequency conversion technology) function in order to solve the problem of stuttering and tearing in high refresh rate screens. But when the Freesyn function is turned on, for the same gray scale (such as L128), the rapid switching of the refresh rate will cause the brightness of the gray scale to change, and the screen will flicker, and the flickering degree will seriously affect the display effect or the quality of the display device. Reduce user experience. The main reason for the screen flickering phenomenon when switching the re...
