Pixel structure and array substrate

Abstract

The invention provides a pixel structure and an array substrate. The pixel is divided into three sub-pixels, namely a main region sub-pixel, a middle region sub-pixel and a sub-region sub-pixel, the main region sub-pixel, the middle region sub-pixel and the sub-region sub-pixel are respectively connected to the same data line through different thin film transistors, and then charging and discharging of a liquid crystal capacitor are controlled. Gates of the first thin film transistor, the second thin film transistor and the fourth thin film transistor are connected to the same gate line Gn, and the Gn outputs high and low levels. The third thin film transistor is located on the next gate line Gn+1 and controls the voltage of the sub-region sub-pixel. The grid electrode of the fifth thin film transistor is connected with the grid electrode line Gn to control the voltage of the middle region sub-pixel. The voltage of a shared electrode (Share barcom) in the middle region sub-pixel is direct-current voltage and can be conveniently adjusted, so that the liquid crystal display panel is favorable for changing the guidance of the liquid crystal and improving the visual angle. The array substrate adopts a column inversion mode and a cross charge-discharge framework, so that a dot inversion mode is formed, the flicker of the display panel can be effectively reduced, and the power consumption is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel structure and an array substrate. Background technique [0002] LCD (Liquid crystal displays, liquid crystal displays) mainly realizes picture display by modulating the light field intensity of the backlight source through thin film transistors (Thin Film Transist, TFT), and has become the mainstream Flat Panel Display (FPD) technology in TV applications. The multi-domain vertical alignment (Multi-Vertical Alignment, MVA) mode has been widely used for its characteristics of frictionless process, high contrast, wide viewing angle and fast response time. [0003] However, the birefringence of the liquid crystal molecules of the multi-domain vertical alignment liquid crystal display panel has a large difference under different viewing angles, resulting in a large viewing angle shift in the vertical alignment liquid crystal display panel. Low color shift is the disad...

[0003]However, the birefringence of the liquid crystal molecules in the multi-domain vertical alignment type liquid crystal display panel has a large difference at different viewing angles, resulting in a large vertical alignment type liquid crystal display panel. Low color shift is the consistent pursuit of vertically aligned liquid crystal display panels
