Eight domain pixel structure

Abstract

The invention discloses an eight domain pixel structure. The eight domain pixel structure comprises a plurality of subpixels arranged in an array form in a liquid crystal display panel, each subpixelis divided into a primary region and a secondary region, one scanning line is respectively arranged corresponding to each line of the subpixels, the scanning line is located between the primary regionand the secondary region, and two neighboring columns of subpixels share the same data line; the primary region of the subpixel further comprises a first thin film transistor, a primary region storage capacitor and a primary region liquid crystal capacitor, the secondary region of each subpixel further comprises a second thin film transistor, a third thin film transistor, a secondary region storage capacitor, a secondary region liquid crystal capacitor and a sharing discharging rod; in each subpixel, the first scanning line corresponding to the subpixel is electrically connected between the first thin film transistor and the second thin film transistor, and the first scanning line crosses over a second scanning line corresponding to the subpixel adjacent to the subpixel. With the eight domain pixel structure provided by the invention, a horizontal crosstalk problem in the eight domain pixel structure is eliminated, and aperture opening ratio of the eight domain pixel structure is improved greatly.

Description

technical field [0001] The invention relates to the technical field of display driving, in particular to an eight-domain pixel structure. Background technique [0002] Liquid crystal displays include twisted nematic (TN) mode, electronically controlled birefringence (ECB) mode, in-plane switching mode (IPS) and vertical alignment (VA) and other display modes. Among them, VA mode is a high-contrast, A common display mode with advantages such as wide viewing angle and no frictional alignment. At present, the VA pixel design of 3T_8domain (8 domains and 3 transistors) is generally adopted, so that the rotation angles of the liquid crystal molecules in the 4 domains of the main (main) area and the 4 domains of the sub (sub) area in the same sub pixel (sub pixel) are different. same, thereby improving color cast. [0003] Such as figure 1 As shown in , it is a schematic diagram of an equivalent circuit of an existing 8-domain pixel structure. In one sub-pixel, the scanning li...

Problems solved by technology

[0005] The present invention provides an eight-domain pixel structure, which can eliminate the horizontal crosstalk problem and greatly increase the aperture ratio of the eight-domain pixel structure to solve the existing eight-domain pixel structure. In order to solve the horizontal crosstalk problem, the sub-pixel structure in the sub-region A shared discharge rod is added for sub-region sub-pixel leakage, which greatly reduces the technical problem of the eight-domain pixel structure aperture ratio
