Abstract

The invention provides a compensation method and device for a display panel. The compensation method of the display panel includes obtaining the first display grayscale of the target pixel in the current frame and the second display grayscale of the target frame; when the first display grayscale is smaller than the second display grayscale, according to the first display grayscale Calculation of the voltage variation of the driving voltage caused by the liquid crystal capacitance of the target pixel and the second display grayscale; determine the grayscale compensation amount corresponding to the voltage variation according to the grayscale voltage distribution of the second display grayscale; The target pixel is overdrive compensated. In this way, by calculating the voltage variation of the driving voltage caused by the liquid crystal capacitance of the target pixel according to the first display grayscale and the second display grayscale, the influence of the liquid crystal capacitance on the driving voltage of the display panel is introduced, which helps to provide more accurate driving voltage, reducing the possibility of flickering and afterimages on the display panel, which helps to improve the display effect.

Description

A compensation method and device for a display panel technical field [0001] The present invention relates to the field of display technology, and in particular, to a compensation method and device for a display panel. Background technique [0002] With the development of display technology, large-sized liquid crystal display panels are more and more favored by users, but, however, Large-sized display panels have higher requirements on response time, so, however, existing display panels can be used for a long time. Flickering and afterimages can occur, affecting the display effect. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a compensation method and device for a display panel to solve the existing phenomenon that the panel may appear There are flickering and afterimages, which affect the display effect. [0004] In the first aspect, an embodiment of the present invention provides a compensation method for a display panel, comprising t...
