Problems solved by technology

However, regardless of using bumps or openings to increase the lateral electric field in the pixel area, the difficulty encountered in the application is the configuration between the pixel electrodes, such as image 3 The configuration between the pixel electrode P2 and the pixel electrode P3 must consider the size of the fringe electric field between the pixel electrodes and the crosstalk (crosstalk...

Abstract

The invention discloses a homeotropic liquid crystal display and a pixel structure thereof. The homeotropic liquid crystal display comprises an upper substrate and a lower substrate; two pixels are defined by two data lines of the lower substrate and every two scanning lines; each pixel comprises a pixel electrode and a transistor; a slot is kept between the pixel electrodes of the two pixels; and a bias electrode is arranged below the slot; wherein the bias electrode has a voltage valve VE; the pixel electrode has a voltage valve VP, and when the voltage value is in a positive frame, VP is larger than VE, and when the voltage value is in a negative frame, VP is less than VE.

Description

technical field [0001] The invention relates to a vertical alignment liquid crystal display, in particular to a pixel structure of a vertical alignment liquid crystal display. Background technique [0002] Vertical alignment (Vertical Alignment) types of liquid crystal displays, such as multi-domain vertical alignment (MVA, Multi-domain Vertical Alignment), change the liquid crystal molecules to be arranged in a non-uniform direction to improve the viewing angle of the display and shorten the response time. [0003] figure 1 A known vertical alignment liquid crystal display is shown. exist figure 1 In order to change the alignment direction of the liquid crystal molecules 12, after the pixel electrodes 4 are deposited on the surface of the lower glass substrate 2, the bumps 6 for alignment control are formed above the pixel electrodes 4; similarly, when making the color filter At the same time, the bumps 8 are also formed under the upper glass substrate 14 and the common ...
