Liquid crystal display device and drive method thereof

Abstract

The invention provides a liquid crystal display device which comprises multiple first pixel groups and multiple second pixel groups which are distributed in an array mode. The first pixel groups and the second pixel groups are alternately arranged both in the pixel row direction and in the pixel column direction, the first pixel groups comprise first pixels and second pixels, and the second pixel groups comprise third pixels and fourth pixels; a grid line is arranged for each pixel row, so that grid voltage is transmitted to the corresponding pixels; the grid voltage is sequentially supplied to the grid line arranged in the n pixel row, the grid line arranged in the (n+2) pixel row, the grid line arranged in the (n+1) pixel row and the grid line arranged in the (n+3) pixel row, and the value of n adopts 1, 5, 9, 13,17, 21,...according to the preset time interval. The invention further provides a drive method of the liquid crystal display device. According to the liquid crystal display device and the drive method thereof, the phenomenon that the pixels generate data voltage fault charging due to existence of RC delay can be avoided, therefore, color cast of pixel display is improved, and the display effect of the liquid crystal display device is improved.

Description

Technical field [0001] The present invention belongs to the field of display technology, and specifically relates to a liquid crystal display device and a driving method thereof. Background technique [0002] Generally, a liquid crystal display (LCD) device has a liquid crystal material injected between a color filter substrate and a thin film transistor (TFT) substrate, where a common electrode and color filters are formed on the color filter substrate, and the thin film transistor substrate is formed with TFT and pixel electrode. In this type of LCD device, different voltages are applied to the pixel electrode and the common electrode to change the distribution of liquid crystal particles, thereby controlling the light transmittance of the liquid crystal, thereby displaying images. Controlling the light transmittance of the liquid crystal can realize the control of the light passing through the LCD. [0003] The color filter in the RGBW liquid crystal display device generally i...

Problems solved by technology

[0005] However, when a liquid crystal display device arranged in a corrugated tile matrix pixel displays a solid-color picture, the data voltage output by the data line is an overload voltage signal, and due to the RC delay (ie RCdelay), the pixels of the liquid crystal display device are easily Mischarging of data voltage occurs, which causes color shift of pixel display and reduces the display effect of liquid crystal display device
