Abstract

A voltage compensation method for a display panel, comprising: acquiring a grayscale value of an Nth frame of a plurality of pixel points and a grayscale value of an (N-1)th frame of the plurality of pixel points (S102); determining a compensation voltage value of the Nth frame of the plurality of pixel points according to the grayscale value of the Nth frame of the plurality of pixel points, the grayscale value of the (N-1)th frame of the plurality of pixel points, and a preset rule, the preset rule comprising a correlation between the grayscale value of the Nth frame of the plurality of pixel points, the grayscale value of the (N-1)th frame of the plurality of pixel points, and the compensation voltage value of the Nth frame of the plurality of pixel points (S104); and processing an input voltage value of the Nth frame of the plurality of pixel points and the compensation voltage value, so as to obtain an actual input voltage, and inputting the actual input voltage to the display panel (S106).

Description

technical field [0001] The present application relates to the field of display technology, in particular to a voltage compensation method for a display panel. Background technique [0002] TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display) when the TFT (Thin Film Transistor, Thin Film Transistor) is turned on to off, the charge on the pixel electrode no longer flows to the data line, and will enter the charge conservation . [0003] Because of the parasitic capacitance between the gate and the source, the voltage on the pixel electrode will have a variation, which causes the pixel voltage set by the data line to change after the TFT is turned off. And this fluctuating voltage will not only cause the final gray scale displayed by the pixel to deviate from the desired gray scale originally written in the voltage. It will also cause the original data line to write positive and negative polarity symmetrical voltages, which will d...
