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, as shown in Figure 1B
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.

Embodiment Construction

[0053] Please refer to FIG. 2A and FIG. 2B , both of which represent schematic diagrams of a simplified model of a polarizer that will be used in the formula derivation process. As shown in FIGS. 2A and 2B , the polarizer includes a glass substrate (H) 21, an adhesive layer (G) 22 and a polarizer body (P) 23, wherein the polarizer body 23 is adhered to the glass substrate 21 by the adhesive layer 22 s surface.

[0054]In addition, between deriving the "thermal expansion coefficient" of the upper and lower polarizers of the liquid crystal display panel module of the present invention and the "thickness" of the two adhesive layers that respectively adhere the two polarizers to the upper and lower substrates of the liquid crystal display panel module of the present invention Before the relational expression, the following assumptions must be established to simplify the process of formula derivation, and these assumptions are as follows:

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. 1A is a schematic diagram of a conventional 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 . ...
