Problems solved by technology

However, as a transparent conductive layer, the ITO layer is usually prepared by ion beam sputtering or evaporation. During the preparation process, a high vacuum environment and heating to 200°C~300°C are required. Therefore, the preparation cost of the ITO layer higher
In addition, after the ITO layer is continuously bent, the resistance at the bend increases. As a transparent conductive layer, it has the disadvantages of insufficient mechanical and chemical durability, and there is a phenomenon of uneven resistance and a small range of resistance values.
As a result, existing touch screens have disadvantages such as poor durability, low sensitivity, and poor accuracy.

Embodiment Construction

[0022] The touch screen panel provided by the present invention and the manufacturing method thereof will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] see figure 1 and figure 2 , the embodiment of the present invention provides a touch screen panel 10 , the touch screen panel 10 includes an insulating substrate 12 , an adhesive layer 13 , a transparent conductive layer 14 , at least one electrode 16 , and a conductive circuit 18 .

[0024] The touch screen panel 10 defines two areas: a touch area 10A and a wiring area 10B. The touch area 10A is an area where the touch screen panel 10 can be touched to realize a touch function, and the wiring area 10B is an area where the conductive lines 18 in the touch screen panel 10 are disposed. The wiring area 10B is a small area near the edge of the touch screen panel 10 , which may be located on at least one side of the touch area 10A. The touch area 10A is a rel...

Abstract

The invention relates to a touch screen panel. The touch screen panel is defined into two areas, namely a touch area and a routing area; the touch screen panel comprises an insulated base with a surface, an adhesive layer, a transparent conductive layer, at least one electrode, and a conductive circuit, wherein the adhesive layer is arranged on the surface of the insulated base; the transparent conductive layer comprises a carbon nano tube layer and is fixed on the surface of the insulated base through the adhesive layer; at least one electrode is electrically connected with the transparent conductive layer; the conductive circuit is electrically connected with the at least one electrode; the transparent conductive layer is just arranged on the touch area; the conductive circuit is just arranged on the surface of the adhesive layer in the routing area, and the touch screen panel further comprises a carbon nano tube wire arranged between the conductive circuit and the adhesive layer.

Description

technical field [0001] The invention relates to a touch screen panel, in particular to a touch screen panel based on carbon nanotubes. Background technique [0002] In recent years, along with the high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, the number of electronic devices in which a light-transmitting touch panel is mounted on the front of a display device such as a liquid crystal is increasing. A user of such an electronic device performs operations by pressing the touch panel with a finger, a stylus, or the like while visually confirming display contents of a display device located behind the touch panel through the touch panel. Thereby, various functions of the electronic device can be operated. [0003] According to different working principles and transmission media of touch screens, existing touch screens are divided into four types, namely resistive type, capacitive type, infrared type and su...
