Problems solved by technology

[0002] At present, the color display market is more and more widely used, and the requirements for high-contrast negative color display are getting higher and higher. The existing TFT technology or CSTN display technology not only has high mold cost, but also high cost. TN type field switching display negative display technology, the background color is relatively blue, it is easy to cause color interference when mixing colors, resulting in deviation of mixed colors
Although the general vertical alignment technology has good contrast and good viewing angle, it has a slow response time and is difficult to achieve color display.

Abstract

The invention relates to a vertically-arranged color liquid crystal display. The display comprises a main control panel and an LCD body, wherein the LCD body is sequentially composed of an upper polarizing plate, an upper phase difference plate, an upper glass substrate, an upper ITO conducting glass layer, an upper PI orientation film layer, a frame adhesive layer, an intermediate space layer, alower PI orientation film layer, a lower ITO conductive glass layer, a lower glass substrate and a lower polarizing plate. By the adoption of the scheme, a vertical orientation technology with the boxthickness of 2-3 [mu]m is adopted for enabling a twisting angle of a liquid crystal to be 90-180 degrees; and by reducing a viscosity coefficient of the liquid crystal to be less than 25 (mm2.s-1) and increasing a drive Vop to a maximum design value (Vop-0.3)V of an IC, the liquid crystal is ensured to have a maximum response capability under the driving of a high voltage, so that the novel fieldswitching color liquid crystal display with high contrast, wide contrast and high purity is realized.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a color vertical alignment liquid crystal display. Background technique [0002] At present, the color display market is more and more widely used, and the requirements for high-contrast negative color display are getting higher and higher. The existing TFT technology or CSTN display technology not only has high mold cost, but also high cost. TN type field switching display negative display technology, the background color is relatively blue, it is easy to cause color interference when mixing colors, resulting in deviation of mixed colors. However, although the general vertical alignment technology has a good contrast ratio and a good viewing angle, the response time is slow and it is difficult to realize color display. Contents of the invention [0003] The present invention uses vertical alignment technology and optical phase difference retardation...
