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.

Abstract

The invention relates to a touch screen panel. Two areas including a touch area and a routing area are defined on the touch screen panel. The touch screen panel comprises an insulating substrate, a transparent conductive layer, at least one electrode and a conductive circuit, wherein the insulating substrate is provided with a surface; the transparent conductive layer comprises a carbon nano tube layer; the electrodes are electrically connected with the transparent conductive layer; the conductive circuit is connected with the electrodes; the transparent conductive layer is only arranged on a portion, which is positioned on the touch area, of the surface of the insulating substrate; and the conductive circuit is only arranged on a portion, which is positioned on the routing area, of the surface of the insulating substrate.

Description

technical field [0001] The invention relates to a touch screen panel and a touch screen, in particular to a carbon nanotube-based touch screen panel and a touch screen. 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, cap...
