Embodiment Construction

[0024] A VA full viewing angle LCD display, such as figure 1 As shown, it includes a plane polarizer, a plane glass substrate, a plane substrate ITO layer, a plane substrate PI alignment layer, a liquid crystal layer, spacers, a bottom substrate PI alignment layer, a bottom substrate ITO layer, and a bottom substrate stacked from top to bottom. Glass substrate and bottom polarizer, and edge glue for sealing surface substrate PI alignment layer, liquid crystal layer, and bottom substrate PI alignment layer.

[0025] In order to expand the display viewing angle range of the LCD display, the same pixel on the ITO layer of the surface substrate and the ITO layer of the bottom substrate of the present invention is divided by a plurality of evenly distributed thin strip-shaped hollow strips. see figure 2 . That is, each pixel of the ITO layer of the surface substrate and the ITO layer of the bottom substrate is provided with several thin strip-shaped hollow strips. The hollow st...

Abstract

The invention discloses a VA all-perspective LCD and a manufacturing method thereof. Every independent pixel is cut by a plurality of hollowed-out small thin strips, an inclined acting force is applied to liquid crystal molecules so that the liquid crystal molecules deflect, the circumstances that initial inclination angles of liquid crystal molecules of an existing vertical alignment type liquid crystal panel are insufficient due to insufficient strength of friction of an alignment layer or uneven friction, a preset angle cannot be achieved in a working process, light cannot pass and then black spots are generated are avoided, and display characteristics of ultra-wide visual angle, high-contrast display, zero chromatic dispersion and the like are realized. In addition, an existing conventional VA production line is not required to be improved, and the VA all-perspective LCD can be produced directly on the basis of the conventional VA production line.

Description

technical field [0001] The invention relates to the technical field of LCD manufacturing, in particular to a VA full viewing angle LCD display and a manufacturing method thereof. Background technique [0002] In terms of the division levels of different positioning of the display, LCD panels also have different types of divisions. At present, the more common LCD displays on the market include TN-type LCD displays, HTN-type LCD displays, STN-type LCD displays and VA panels. Compared with other types of LCD monitors such as TN, HTN or STN, VA-type LCD monitors completely avoid the dispersion problem in principle, and the display contrast has also been greatly improved (above 500), which meets the needs of some customers. Demand for high-end performance LCD displays. However, some customers have also put forward higher requirements for the display viewing angle range, which is a problem that conventional VA-type LCD displays cannot meet. How to improve the design or process ...
