Abstract

The utility model discloses an integrated capacitive sensing touch screen. The integrated capacitive sensing touch screen comprises a functional layer (1) and an outer covering layer (2), wherein the functional layer is covered with the outer covering layer. A masking frame (3) is arranged on the upper surface of the functional layer. The top surface of the outer covering layer is an arc-shaped curved surface. The functional layer is formed by sequentially stacking a transparent substrate (11), a silicon dioxide layer (12), a niobium pentoxide layer (13), a black resin layer (14), an ITO electrode layer (15), a metal electrode layer (16) and an insulating layer (17) from bottom to top. The ITO electrode layer is composed of two electrodes insulated from each other. The thickness of the transparent substrate is 0.9 mm. The integrated capacitive sensing touch screen is compact in structure and good in sealing performance and light transmission performance.

Description

A kind of integrated capacitor induction touch panel

Technical field

The utility model relates to a kind of integrated capacitor induction touch panel.

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; Therefore, be necessary to design the better integrated capacitor induction touch panel of a kind of sealing and light transmission.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of integrated capacitor induction touch panel, and this integrated capacitor induction touch panel compact conformation, has good sealing property and light transmission.

The technical solution of utility model is as follows:

A kind of integrated capacitor induction touch panel, comprises functional layer (1) and encases the surrounding layer (2) of functional layer outward; Be provided with masking frame (3) at the upper surface of functional layer; The end face of surrounding layer is arc-shaped curved surface;

Described functional layer 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 0.9mm.

Beneficial effect:

Integrated capacitor induction touch panel 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.
