Black film liquid crystal display screen and its box manufacture process

Abstract

There is a sort of black-film liquid crystal display screen, and it consists of the up-slice of the glass, the below-slice, the stayed strip of the frame, the conducting circuit layer, the black compensated film, the tropism PI layer, and the first isolation ball which is used for isolating the up-slice of the glass and the below-slice. There has the annular stayed frame in the frame film of the compensated film, this stayed frame has the second isolation ball, and the diameter of the second isolation ball is small than the diameter of the first isolation ball. The stayed frame is added in the black film, the inner and the outer of the frame adopts the gasket material which have different diameter, the black film liquid crystal display which is made by this method is heated, the stayed frame eliminates the difference of the deep of the box of the BM and the ITO lattice completely, it can reach the famous effect.

Description

technical field [0001] The invention relates to a display device, in particular to a structure of a black film liquid crystal display screen and a manufacturing method thereof. Background technique [0002] With the development of LCD black and white display technology to this day, the main challenge is how to improve its response speed and contrast. Improving the response speed is mainly achieved by reducing the thickness of the cell and selecting a liquid crystal material with a relatively fast response; and improving the contrast is mainly achieved by selecting a suitable polarizer and liquid crystal material from the perspective of materials; and from the perspective of technology, making A black film product (full or semi-transparent) is a good choice. In the prior art, the production process of black film LCD is the same as that of conventional LCD products (see Figure 1), because the film thickness of black compensation film (BM) is generally above 1.2UM, and the fil...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a black film liquid crystal display screen and its box-making process. It adopts the form of printing a support frame on the BM, and the liner in the support frame is lined with a slightly smaller diameter than the liner in the box. To achieve the function of support, it can also eliminate the problem of uneven box thickness caused by the existence of the BM layer, and solve the technical problems of poor overall consistency, low product qualification rate and inconsistent display in the prior art
