Pixel structure of horizontal electric field liquid crystal display

Abstract

The invention discloses a pixel structure, and particularly relates to a pixel structure of a horizontal electric field liquid crystal display. The pixel structure comprises a transistor array substrate and a color filter substrate, wherein the transistor array substrate and the color filter substrate are oppositely arranged. The transistor array substrate comprises a pixel electrode and a shared electrode, wherein the pixel electrode comprises a first part and a plurality of second parts, and the second parts extend from the first part. The shared electrode comprises a first part and a plurality of second parts, wherein the second parts extend from the first part. The second parts of the shared electrode and the second parts of the pixel electrode are alternatively arranged on the substrates in parallel. The color filter substrate comprises a shielding electrode, and the shielding electrode shields the area from the front ends of the second parts of the shared electrode to the pixel electrode and the area from the front ends of the second parts of the pixel electrode to the shared electrode.

Description

technical field [0001] The invention relates to a touch-type liquid crystal display, in particular to a horizontal electric field liquid crystal display. Background technique [0002] Liquid crystal display technology can be divided into twisted nematic liquid crystal display (TN-LCD) and horizontal electric field (horizontal electric field type) liquid crystal display according to the twisting direction of liquid crystal molecules. In a twisted nematic liquid crystal display, the liquid crystal molecules will rotate with the change of the vertical electric field between two opposing glass substrates. In the horizontal electric field liquid crystal display, the common electrode and the pixel electrode are formed on the transistor array substrate at the same time to provide a transverse electric field (transverse electric field), so that the liquid crystal molecules can rotate horizontally with the change of the transverse electric field. Compared with the twisted nematic li...

Problems solved by technology

[0004] figure 1 The in-plane switching mode liquid crystal display can cooperate with the touch panel to form a touch-sensitive liquid crystal display. When the touch-sensitive display is pressed, the arrangement state of the liquid crystal molecules near the pressed point will be changed. After the pressed state, the liquid crystal molecules must return to the pressed state again. However, the liquid crystal molecules located in the disclination region, such as region A, may not be able to return to the correct alignment state according to the distribution of the electric field, resulting in uneven brightness.
