Debugging method of liquid crystal display device

Abstract

The invention provides a debugging method of a liquid crystal display device. According to the debugging method of the liquid crystal display device, when the liquid crystal display device displays the detection picture corresponding to the selected gray scale, the corresponding binding point voltage group and the common voltage are adjusted, so that the crosstalk parameter of the detection picture meets the requirement; therefore, the target common voltage corresponding to the selected gray scale is obtained; when the liquid crystal display device displays the detection picture correspondingto other binding point gray scales, the public voltage is adjusted, so that the crosstalk parameter of the detection picture meets the requirement; Therefore, the target common voltage corresponding to the gray scales of other binding points is obtained. further obtaining an optimal common voltage and adjusting the common voltage to the optimal common voltage; and then when the liquid crystal display device displays the detection picture corresponding to other binding point gray scales, the corresponding binding point voltage group is adjusted, so that the crosstalk parameter of the detectionpicture meets the requirement, the crosstalk phenomenon of the liquid crystal display device can be effectively improved, and the display effect of the liquid crystal display device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a debugging method for a liquid crystal display device. Background technique [0002] In the field of display technology, flat panel display devices such as liquid crystal display devices (Liquid Crystal Display, LCD) have gradually replaced cathode ray tube (Cathode Ray Tube, CRT) display devices. The liquid crystal display device has many advantages such as a thin body, power saving, and no radiation, and has been widely used. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. Generally, a liquid crystal display panel consists of a color filter (Color Filter, CF) substrate, a thin film transistor (Thin Film Transistor, TFT) array substrate, a liquid crystal (Liquid Crystal, LC) and a sealant sandwiched between the color filter substrate a...

[0005] However, when the driving voltages of adjacent pixels are kept opposite in polarity by column inversion, the black-and-white-frame picture or the gray-and-white-frame picture of the liquid crystal display device (such as figure 1 shown) exhibits crosstalk, see for example figure 1 , in the white frame screen 10 with a gray background, a dark line 12 and a bright line 13 appear on the upper and lower sides of the white frame 11, or abnormal areas or abnormal lines appear on the left and right sides of the white frame, which will cause abnormal distortion of the display screen , reducing the display effect of the liquid crystal display device
