Embodiment Construction

[0053] figure 2 It is a schematic cross-sectional view of a polarizing plate according to the first embodiment of the present invention. Such as figure 2 As shown, the polarizer 100 includes: a first protective film 110, a second protective film 180, a pressure-sensitive adhesive layer 120, a light-shielding pattern 130, a first substrate layer 140, a second substrate layer 160 , a polarizing layer 150 and a surface treatment layer 170 .

[0054] In the first embodiment of the present invention, the polarizing layer 150 is disposed on the first substrate layer 140 . The second substrate layer 160 is disposed on the polarizing layer 150 such that the polarizing layer 150 is located between the first substrate layer 140 and the second substrate layer 160 . The polarizing layer 150 is a polyvinyl alcohol (Poly Vinyl Alcohol; PVA) film, but not limited thereto. For example, polyvinyl alcohol (PVA) is a soft and transparent plastic, in which iodide ions are diffused and permeat...

Abstract

The invention discloses a polarizer as well as a touch control liquid crystal panel and a touch control display of the polarizer. The polarizer comprises a first substrate layer, a polarized light layer, a second substrate layer, a pressure sensing adhesive layer and a shading pattern, wherein the polarized light layer is arranged on the first substrate layer; the second substrate layer is arranged on the polarized light layer so as to ensure that the polarized light layer is arranged between the first substrate layer and the second substrate layer; the pressure sensing adhesive layer is formed on the lower surface of the first substrate layer so as to ensure that the first substrate layer is arranged between the polarized light layer and the pressure sensing adhesive layer; and the shading pattern is formed between the second substrate layer and the pressure sensing adhesive layer.

Description

technical field [0001] The present invention relates to a polarizing plate, in particular to a polarizing plate capable of improving stiffness, and a touch liquid crystal panel and a touch display using the polarizing plate. Background technique [0002] A touch panel is an interface tool widely accepted by the public as an interface tool for information exchange. Currently, there are mainly two types of touch panels widely used, namely resistive and capacitive. [0003] figure 1 It is a schematic cross-sectional view of a touch display in the prior art. The structure of the general touch display 900 is adopted between the protective glass 910 (Cover Lens) and the liquid crystal display module 930 (Liquid Crystal Display Module, LCM), plus a layer of touch sensor (Touch Sensor) 920 multi-layered structure. Since the traditional touch panel must use 1~2 pieces of glass to make the touch sensor, plus a protective glass, it has disadvantages such as increased thickness of t...
