LCD with vertical alignment mode

Abstract

A vertically aligned (VA) mode liquid crystal display (LCD) comprises an upper transparent substrate, an upper electrode, an upper vertically aligned layer, a negative liquid crystal layer, a lower vertically aligned layer, a lower electrode and a lower transparent substrate; the upper electrode consists of a plurality of abreast upper stripy electrodes; the lower electrode consists of a plurality of abreast lower stripy electrodes; the upper stripy electrodes and the lower stripy electrodes are intersected with each other; an overlapping area is a pixel region; the pixel region is characterized in that in each pixel region, the upper stripy electrodes are divided into a plurality of upper stripy sub-electrodes by an upper groove formed in the wiring direction of the upper stripy electrodes; the lower stripy electrodes are divided into a plurality of lower stripy sub-electrodes by a lower groove formed in the wiring direction of the lower stripy electrodes; the electric conductivity is kept among upper stripy sub-electrodes belonging to the same upper stripy electrode; and the electric conductivity is kept among lower stripy sub-electrodes belonging to the same lower stripy electrode. The VA mode LCD can achieve a multidomain display without perspective blind area, can be design as high way drive, and has the advantages of simple structure, technological process, low cost, short design cycle and high reliability.

AI Technical Summary

Problems solved by technology

At present, there are VA mode displays with dynamic drive (that is, the passive matrix drive mode), which use friction for orientation, but this orientation method cannot realize multi-domain display, so that there is a blind area in its viewing angle, and the blind area is in high-channel drive. The bottom will be shifted to the positive viewing angle, so this method cannot realize high-channel drive, and can only be applied to pen-type products with low channel count (<10 channels)

In addition, the process of friction orientation may also lead to the introduction of dust and other foreign matter, the occurrence of static electricity and friction damage, which will reduce the production yield
