Liquid crystal display device driving method and liquid crystal display device

Abstract

The invention provides a liquid crystal display device driving method and a liquid crystal display device. The method comprises the following steps: receiving image data entering a time schedule controller; calculating an area, exceeding a preset degree, of a coupling phenomenon appearing in a display image corresponding to the image data; judging whether the area, exceeding the preset degree, of the coupling phenomenon appearing in the display image corresponding to the image data is greater than or equal to a preset area or not; and if so, driving the liquid crystal display device in a two-column inversion mode, wherein when the liquid crystal display device is driven in the two-column inversion mode, a data signal S(n+2) and a data signal S(n+3) are opposite in driving direction at a same time, wherein n is equal to zero or represents a positive even number.

Description

technical field [0001] The invention relates to the field of display, in particular to a method for driving a liquid crystal display device and the liquid crystal display device. Background technique [0002] In a Gate Drive on Array (GOA) liquid crystal display device, the low-level signal (Vss), one of the control signals of the GOA circuit, will have noise sources in the voltage stabilization stage, such as the gate line and the data line. noise in between. see figure 1 , usually, a liquid crystal display device includes gate lines ( figure 1 Marked as Gate line) and data line ( figure 1 marked as Data line), the gate line and the data line are insulated and staggered, and a thin film crystal ( figure 1 marked as TFT) tube is arranged between the gate line and the data line, and the gate of the thin film transistor is electrically connected to the gate line, the drain of the thin film transistor is electrically connected to the data line, and the thin film transistor ...

AI Technical Summary

Problems solved by technology

When the coupling polarity of the two data lines corresponding to the gate line on the gate line is the same, more noise will be generated, which will cause the high-frequency mura phenomenon to appear in the image displayed by the liquid crystal display device, and the mura phenomenon is easy Deterioration over time, resulting in degradation of GOA circuit characteristics over time
