LCD (liquid crystal display) liquid crystal display module

Abstract

The invention relates to an LCD (liquid crystal display) liquid crystal display module, which comprises a back light source, glass, a flexible circuit board, an upper polaroid, a lower polaroid, a driving chip and a touch screen, wherein an encapsulation structure is sequentially provided with the touch screen, the upper polaroid, the glass, the lower polaroid and the back light source from top to bottom in a laminated way, a single-layer region is formed on the glass, the flexible circuit board and the driving chip are arranged on the single-layer region, the length of the lower polaroid is the same as the length of the upper polaroid, a single-side sticky release film is pasted on the lower surface of the single-layer region of the glass, and is used for providing the support for the glass, and the back light source is pasted / covered with the single-side sticky release film and the lower polaroid through curtain tapes. The LCD liquid crystal display module has the advantages that the single-side sticky release film is used for structurally replacing an extended lower polaroid to realize the support effect on a glass thin film transistor, one sticky side of the single-side sticky release film enables the single-side sticky release film to be firmly pasted on the glass, and the release side avoids the firm pasting with the curtain tapes, so the occurrence of condition of edge corner crack breaking of the single-layer region of the glass caused by outward deformation of the back light source is avoided.

Description

【Technical field】 [0001] The invention is applied in the field of LCD liquid crystal displays, and in particular relates to the structural design for protecting polarizers and liquid crystal picture tubes in LCD liquid crystal display modules. 【Background technique】 [0002] The invention is mainly aimed at the LCD liquid crystal display module, which mainly includes a backlight source, glass, a flexible circuit board, a polarizer, a driving chip and a touch screen. In terms of packaging structure, the backlight is installed on the bottom layer, the touch screen is on the top layer, glass, flexible circuit board and driver chip are arranged in the middle, and the polarizer includes an upper polarizer and a lower polarizer, which are respectively stacked on the glass. above and below, and the glass itself includes a color filter and a thin film liquid crystal tube, the color filter and the thin film liquid crystal tube are stacked, the color filter is close to the position of...

AI Technical Summary

Problems solved by technology

Then the lower polarizer cannot provide support for the single-layer area of ​​the thin-film liquid crystal tube, and the single-layer area of ​​the thin-film liquid crystal tube is too fragile. Under the action of vertical external force, the single-layer area of ​​the glass will also have chipping.
