Liquid crystal display device

Abstract

The invention provides a liquid crystal display device. The liquid crystal display device comprises a plurality of sub-pixels which are arrayed, wherein each sub-pixel is an eight-domain structure; the polarities of data signals of two adjacent two columns of sub-pixels are opposite in a frame, and the polarities of data signals of the same sub-pixel are opposite in two adjacent frames; and each two adjacent sub-pixels in a row direction form a sub-pixel group, the sub-pixels in one sub-pixel group in two adjacent sub-pixel groups display the luminance of a first display gray scale corresponding to the sub-pixels, and the sub-pixels in the other sub-pixel group in two adjacent sub-pixel groups display the luminance of a second display gray scale corresponding to the sub-pixels. By carryingout color offset compensation on the data signals of the eight-domain-structured sub-pixels, the chrominance view angle of the liquid crystal display device can be improved, and the observation experience of the liquid crystal display device can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] As far as liquid crystal displays currently on the mainstream market are concerned, they can be divided into three types, namely Twisted Nematic (TN) or Super Twisted Nematic (STN) type, and In-Plane Switching (In-Plane Switching) type. , IPS) type and vertical alignment (Vertical Alignment, VA) type. Among them, the VA type LCD has a very high contrast ratio compared with other types of liquid crystal displays, generally reaching 4000-8000, and has a very ...

Problems solved by technology

[0005] Furthermore, in order to enhance the effect of improving the chromaticity and viewing angle, the prior art also proposes to divide the pixel electrode of a sub-pixel into the main region pixel electrode and the sub region pixel electrode, and then separate the main region pixel electrode and the sub region pixel electrode Compared with the four-domain structure, the eight-domain structure made into a "rice" pattern can improve the viewing angle better, but compared with the IPS-type liquid crystal display and OLED display, its chromaticity and viewing angle are still the same. Very low, needs to be further improved
