Problems solved by technology

[0004] 8-domain pixels have become the pixel design trend of large-size TV panels. However, in order to improve the flicker (Flicker) phenomenon under high resolution and high refresh rate, the balance of the best common voltage (best vcom) between the main area and the sub area is always a problem. difficulty

Embodiment Construction

[0021] see image 3 , which is a schematic diagram of the eight-domain pixel structure of the present invention. Those skilled in the art can understand that the focus of the present invention is on the improvement of the eight-domain pixel structure, so the general structure included in the liquid crystal display panel and the pixel will not be repeated in the following description.

[0022] The eight-domain pixel structure of the present invention includes a plurality of sub-pixels arranged in an array in the liquid crystal display panel, and each sub-pixel is divided into a main area 10 and a sub-area 20, and a scanning line 30 is set corresponding to each row of sub-pixels. The line 30 is interposed between the main area 10 and the sub-area 20, and a data line 40 is provided corresponding to each column of sub-pixels; it also includes a main-area TFT 11 and a main-area storage capacitor, a sub-area thin-film transistor 21 and a sub-area storage capacitor The main area sto...

Abstract

The invention provides an eight-domain pixel structure. The eight-domain pixel structure includes a plurality of sub pixels which are arranged in a liquid crystal display panel in an array manner; each sub pixel includes a main region and a sub region; a scanning line is arranged and corresponding to each line of sub pixels, wherein the scanning line is positioned between the main region and the sub region, and a data line is arranged and corresponding to each row of sub pixels; the eight-domain pixel structure also includes a main region thin film transistor, a main region storage capacitor, a sub region thin film transistor and a sub region storage capacitor; the main region storage capacitor is formed by a first main region storage electrode in a main region range and an opposite common electrode; the sub region storage capacitor is formed by a sub region storage electrode in a sub region range, a second main region storage electrode in the main region range and an opposite common electrode; the sub region storage electrode and the main region storage electrode stride over the scanning lines and communicate with each other. The differential pressure ratio of the main region and the sub region can be controlled, and the problem that difference between the optimal common voltages of the main region and the sub region is too large can be avoided.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to an eight-domain pixel structure. Background technique [0002] A liquid crystal display panel is usually composed of a color filter substrate, a thin film transistor array substrate, and a liquid crystal layer arranged between the two substrates, and pixel electrodes and common electrodes are respectively arranged on the opposite inner sides of the two substrates, and the liquid crystal molecules are controlled to change direction by applying a voltage , to refract the light from the backlight module to generate a picture. Liquid crystal displays include twisted nematic (TN) mode, electronically controlled birefringence (ECB) mode, vertical alignment (VA) and other display modes. Among them, VA mode is a kind of display mode with high contrast, wide viewing angle, and no friction alignment. common display modes for . However, since the vertically rotating liquid crystal i...
