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, the method of removing part of the ITO layer is usually laser etching, which not only has high production cost, but also has low production efficiency.

Embodiment Construction

[0020] The manufacturing method of the touch screen panel provided by the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] see Figures 1 to 7 , an embodiment of the present invention provides a method for manufacturing a touch screen panel 10, which includes the following steps:

[0022] In step 1, an insulating base 12 is provided. A surface of the insulating base 12 includes a plurality of target areas 120 , and each target area 120 defines a touch area 124 and a routing area 122 .

[0023] The insulating base 12 is a curved or planar structure. The insulating base 12 has appropriate transparency and mainly plays a supporting role. The insulating substrate 12 is formed of hard or flexible materials such as glass, quartz, diamond, or plastic. Specifically, the flexible material can be selected as polycarbonate (PC), polymethyl methacrylate (PMMA), polyethylene (PE), polyimide (PI) or...

Abstract

The invention relates to a production method of touch panels. The production method includes the steps of providing an insulating substrate with a plurality of target areas on a surface; forming an adhesive layer on the surface of the insulating substrate; solidifying the adhesive layer in the wiring areas; forming a carbon nanotube layer on the surface of the adhesive layer; solidifying the adhesive layer in each touch area to fix the carbon nanotube layer in the touch area; removing the carbon nanotube layer in the wiring areas to obtain a plurality of spaced transparent conducive layers; forming an electrode and a conductive circuit in the wiring area of each target area; and cutting to obtain a plurality of touch panels, wherein each target area includes one touch area and one wiring area.

Description

technical field [0001] The invention relates to a method for preparing a touch screen panel, in particular to a method for preparing 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 resisti...
