Embodiment Construction

[0017] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] see figure 1 , figure 1 It is a schematic structural diagram of the polarizer 1 according to the first embodiment of the present invention. The polarizer 1 includes a protective film 10, a first cellulose triacetate (TAC) film 11, a polarizing film 12, a second cellulose triacetate film 13, an adhesive layer 14 and a release film, which are sequentially stacked. Type film 15. When the polarizer 1 is attached to the display panel, the release film 15 is torn off, and the polarizer 1 is attached to the display panel through the adhesive layer 14 .

[0019] see figure 2 , figure 2 It is a top plan view of the adhesive layer 14 . The adhesive layer 14 includes an adhesive material and thermal substances distributed in the adhesive material. Preferably, the adhesive material is pressure sensitive adhesive. The mass p...

Abstract

Provided in the invention is a polaroid comprising a glue layer. The glue layer consists of a glue material and a thermal-inductance substance distributed in the glue material. The thermal-inductancesubstance has the characteristic of making a polymerization reaction after being heated and generating high-molecular polymer, so that the light transmittance of the heated part of the polaroid is reduced. With the polaroid, a problem that the conventional polaroid is thermally shrunk and thus the light transmittance becomes non uniform can be solved. In addition, the invention also provides a display device using the polaroid. With the display device, a problem that the conventional polaroid is thermally shrunk and thus the light transmittance becomes non uniform can be solved.

Description

technical field [0001] The invention relates to a polarizer and a display device using the polarizer. Background technique [0002] A polarizer is an optical element with a multilayer structure, which is often used in a display device and attached to a display panel to play a role in polarizing light. Usually, the heat dissipation of the backlight module or the PCB board makes the polarizer in a heated environment, causing the polarizer to shrink, which in turn affects the optical performance of the polarizer. One of the manifestations is that the light transmittance of the higher temperature part of the polarizer will increase. Big. This causes display unevenness on the display panel. Contents of the invention [0003] In view of this, it is necessary to provide a polarizer for solving the problem of uneven light transmittance caused by thermal shrinkage of the polarizer. [0004] In addition, it is also necessary to provide a display device using the polarizer. [00...
