Embodiment Construction

[0016] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0017] Such as figure 1 As shown, a method for preparing lead wires of a capacitive touch screen includes the following steps: designing a lead pattern in advance, printing the pre-set lead pattern on a prepared panel with a sensor by an inkjet printer, and curing it.

[0018] The inkjet printer of the present invention uses special ink for nanometer silver.

[0019] 1. Pre-process: including substrate preparation (such as: substrate strengthening, surface purification, and icon format printing, if necessary), sensor pattern preparation, etc.;

[0020] 2. Lead wire design: professional technicians design lead wire patterns according to customer needs;

[0021] 3. Lead printing: on a special inkjet printer, use nano-silver special ink to print out and cure the pre-designed lead pattern on the designated position of the panel;

[0022] 4. Post process:...

Abstract

The invention provides a preparation method of a lead wire of a capacitive type touch screen, and relates to the technical field of the capacitive type touch screen. The preparation method provided by the invention comprises the following steps of: pre-setting patterns of the lead wire; printing the patterns on a prepared panel with a sensor by using an ink-jet printer; and curing the panel. The invention aims to provide the preparation method of the lead wire of the capacitive type touch screen, which has the advantages of fewer processes, convenience in control of product quality, and high product yield.

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 processes, large equipment investment, difficult quality control, low product qualification rate, and large demand for human resources, resulting in a long-term high price of capacitive touch screens, which is not conducive to its rapid popularization.
