Embodiment Construction

[0015] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0016] Such as figure 1 As shown, a method for preparing a pattern of a capacitive touch screen panel includes the following steps: 1) transferring the transparent conductive layer and the photoresist layer to the panel by means of transfer printing, 2) making get the sensor panel.

[0017] The transparent conductive layer and the photoresist layer of the present invention adopt roll-shaped composite materials prepared in advance.

[0018] 1. Substrate preparation: Prepare the base material of the capacitive touch screen panel to the desired state, including strengthening, surface cleaning, and ICON printing (if necessary);

[0019] 2. Preparation of materials to be transferred: prepare transparent conductive layer and photoresist layer to be transferred;

[0020] 3. Transfer printing: transfer the prepared transparent conductive layer and photoresis...

Abstract

A preparation method for patterns of a sensor of a capacitance touch screen relates to the technical field of manufacture of capacitance touch screens. The preparation method includes following steps: 1) transferring a transparent conductive layer and a photoresist layer on a panel in a transfer printing manner; and 2) preparing the patterns of the sensor by means of exposure, development, etching and stripping. The preparation method for the patterns of the sensor of the capacitance touch screen is simple in technical process, convenient for controlling the quality of products and high in yield of the products.

Description

[0001] technical field [0002] The invention relates to the technical field of making capacitive touch screens. [0003] Background technique [0004] The current capacitive touch screen needs to go through the following processes during production, firstly prepare the panel substrate, then prepare the sensor pattern and prepare the leads. The preparation of the sensor is mainly to coat the transparent conductive layer on the panel, expose after adding the photoresist layer, etch after developing, and remove the film; the preparation of the lead is mainly to coat the prepared sensor first, then add the photoresist layer and then expose. After developing, etch and remove the film. There are many traditional crafts and processes, large investment in equipment, difficult quality control, low product qualification rate, and large demand for human resources, resulting in the long-term high price of capacitive touch screens, which is not conducive to its rapid popularization. ...
