Liquid crystal pixel circuit and liquid crystal display device

Abstract

The invention provides a liquid crystal pixel circuit and a liquid crystal display device. The liquid crystal pixel circuit comprises a plurality of pixels. Each pixel comprises a first pixel region, a second pixel region and a capacitive coupling module; each first pixel region and the corresponding second pixel region are simultaneously electrically connected to a scanning line and a data line; each capacitive coupling module is connected with another scanning line, each first pixel region and the corresponding second pixel region are charged until the first pixel region and the second pixel region have first potential values when the corresponding scanning line is switched on; when each other scanning line is switched on, the corresponding first pixel region is charged until the first pixel region has a second potential value, the corresponding second pixel region is charged until the second pixel region has a third potential value, and each first potential value is smaller than each second potential value and each third potential value. The liquid crystal pixel circuit and the liquid crystal display device have the advantages that the problem of color offset can be solved under the condition of large visual angles while deterioration of the integral brightness of the liquid crystal display device can be prevented, and the penetration rates can be increased.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal pixel circuit and a liquid crystal display device. Background technique [0002] With the development of technology, people have higher and higher requirements for liquid crystal display devices, and the existing VA (Vertical Alignment, vertical alignment) mode liquid crystal display device has very high frontal contrast, but when viewed from the side, due to the VA mode liquid crystal display The characteristics of the molecules rotating in the vertical direction lead to a significant decrease in the contrast of the liquid crystal display device, and there will be obvious color shift phenomenon under different viewing angles. [0003] The existing common method to solve the low color shift phenomenon is: divide each pixel on the liquid crystal display device into a main area and a sub-area, and use a shared capacitor to make the main area and the sub-area o...
