Description

A kind of handset touch panel with novel polaroid

Technical field

The utility model relates to a kind of handset touch panel with novel polaroid.

Background technology

Existing capacitance induction touch panel, because edge does not block, extraneous light easily disturbs the luminous of screen body, and each parts of touch-screen comparatively disperse, adopt non-Unitary structure, therefore while being assembled on casing, easily form gap, thereby cause the impurity such as dust to enter the inside of the electronic product such as mobile phone or flat board; And existing screen body visible angle need promote, therefore, be necessary to design a kind of novel handset touch panel with novel polaroid.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of handset touch panel with novel polaroid, and this has the handset touch panel compact conformation of novel polaroid, and visible angle is large, has good sealing property and light transmission.

The technical solution of utility model is as follows:

There is a handset touch panel for novel polaroid, comprise and touch module 1, liquid crystal display module 4 and from top, encase the surrounding layer 2 that touches module and liquid crystal display module; Be provided with masking frame 3 at the upper surface of functional layer; The end face of covering is arc-shaped curved surface;

Described touch module is formed by stacking successively by transparency carrier 11, silicon dioxide layer 12, niobium pentaoxide layer 13, black resin layer 14, ITO electrode 15, metal electrode layer 16 and insulation course 17 from bottom to up; ITO electrode layer is made up of the electrode of two mutual insulatings;

The thickness of transparency carrier is 1.2mm.

Described liquid crystal display module is made up of top-down upper polaroid, liquid crystal layer, lower polaroid and backlight; Described upper polaroid is multiple superposed structure; On composition, each layer of polaroid is followed successively by from top to bottom: protective seam, AG layer, O type film layer, the first adhesive linkage, TAC supporting layer, PVA layer, phase delay chip, the second adhesive linkage and release film.

Beneficial effect:

The handset touch panel with novel polaroid of the present utility model, arranges masking frame at functional layer upper surface and blocks surround relationship, thereby the visual effect of touch-screen is not vulnerable to the interference of ambient light line, and user is more comfortable; In addition, the end face of surrounding layer is arc-shaped curved surface, therefore, when this screen body coordinates with shell, is not easy to produce gap, and therefore better tightness can effectively prevent that dust from entering.

In addition, to the improved core of upper polarizer with increased refraction and the delay with compensation light of an O type film layer and phase delay chip, thereby increased the visual perspective of display screen, detection shows, display screen after improvement, 160 degree are brought up in horizontal view angle, and vertical angle of view 160 is spent.
