LCD panel module

Abstract

The invention provides a liquid crystal display panel module, the liquid crystal display panel module includes a first baseboard; a second baseboard; a liquid crystal layer that lies between the fist baseboard and the second baseboard; a first polarized board, which lies on the surface of the first baseboard, has a first inflated ratealpha1; a second polarized board, which lies on the surface of the second baseboard, has a second inflated rate alpha2; a first gluey-layer, which forms between the first polarized board and the first baseboard, has a first thickness h1; and a second gluey-layer, which forms between the second polarized board and the second baseboard, has a second thickness h2; wherein the first thickness h1 is different from the second thickness h2, and the first inflated ratealpha1 is the same as the second inflated rate alpha2. The liquid crystal display panel module of the invention will not warp due to the perennial roast from the backlight module, so as to cause the phenomena of 'fringe leaking-light', and further will not scathe the backlight.

Description

technical field [0001] The present invention relates to a liquid crystal display panel module, especially a liquid crystal display panel module (PanelModule) that does not warp and deform due to long-term baking of a backlight module, resulting in "edge light leakage". Background technique [0002] In a liquid crystal display panel module, the polarizer has the function of modulating the polarization direction (polarization) of the light passing through itself, so as to cooperate with the liquid crystal molecules to control the switching of the display unit (pixel) of the liquid crystal display panel. Figure 1A It is a schematic diagram of an existing polarizer 1 applied to a liquid crystal display panel module, which includes a polarizer body 11 made of polyvinyl alcohol (PVA) and two protective layers 121, 122 respectively located on its upper and lower sides, and The polarizer 1 is adhered to the surface of the glass substrate 14 by a pressure-sensitive adhesive (PSA) 13 ...

AI Technical Summary

Problems solved by technology

[0004] After the existing liquid crystal display panel module is used for a long time, the lower polarizer is closer to the backlight module, so the temperature of the lower polarizer is higher than that of the upper polarizer, causing the "shrinkage internal stress" of the lower polarizer to be different from that of the upper polarizer. The "shrinkage internal stress" is not equal

Due to the unbalanced shrinkage internal stress of the upper and lower polarizers, the existing liquid crystal display panel is warped and deformed, such as Figure 1B shown

Due to this warping phenomenon, the edge of the existing liquid crystal display panel module will have the phenomenon of "edge light leakage", and the central part of the liquid crystal display panel is easy to contact with the backlight module 16 below it, resulting in the backlight module. Defects in optical films (such as diffuser films)

Therefore, after a long period of use of the existing liquid crystal display panel module 15, its display quality will be affected by the phenomenon of "edge light leakage" and the defect of the optical film of the backlight module.
