Problems solved by technology

Although it consumes less power than the dot inversion driving method, the N-line inversion driving method tends to cause horizontal dark lines, thus reducing image quality
[0010] In addition, for some image patterns (patterns), such as white block patterns, it is easy to generate vertical interference noise at the top and bottom of the pattern

Abstract

The invention relates to a polarity reversal driving method of a liquid crystal display device and a source driver. During a same frame of display period, a polarity sequence of pixel groups of a plurality of gate lines is reversed, so that the positions of the pixel groups after polarity sequence reversing are distributed in the whole frame uniformly in a space domain. The positions of the pixelgroups after polarity sequence reversing are change at a one-frame interval, so that balanced distribution of the positions of the pixel groups is realized in a time domain.

Description

technical field [0001] The invention relates to a polarity inversion driving method of a liquid crystal display, in particular to a polarity inversion driving method with balanced distribution in space domain and time domain. Background technique [0002] Liquid crystal display (LCD) has the advantages of light weight, low power consumption and no radiation, so it is widely used in various electronic products, such as desktop computers, tablet computers, mobile phones, etc., as output display. [0003] figure 1 A system block diagram of the liquid crystal display 100 is shown. The gate lines GL1 ˜GLn and the data lines DL1 ˜DLm intersect each other to define a plurality of pixels arranged in a matrix on the liquid crystal panel 11 . A thin film transistor TFT and a liquid crystal capacitor Clc are formed in each pixel, serving as a switch and a liquid crystal cell respectively. The voltage difference between the pixel electrode (pixel electrode) and the common voltage (Vc...
