Embodiment Construction

[0037] The invention aims to provide a capacitive touch screen solution which simplifies the process and reduces the product price. Its core is to realize the production of capacitive touch screen through the following technical measures:

[0038] 1. Patterning of the conductive film on both sides of the substrate;

[0039] 2. Use silk screen metal paste as the wire.

[0040] Specifically, the manufacturing process of the touch screen electrode of the capacitive touch screen of the present invention includes the following steps:

[0041] Pattern the conductive film on the first surface (made of materials such as indium tin oxide, aluminum zinc oxide, etc.) and the conductive film on the second surface of the substrate (made of transparent materials such as glass and plexiglass) to form the first set of sensing electrodes and a second set of sensing electrodes;

[0042] Conductor production process, screen printing metal paste (such as silver paste, silver-aluminum paste, et...

Abstract

The invention discloses a method for manufacturing a capacitive touch screen, comprising: an electrode manufacturing process, respectively patterning the conductive film on the first surface and the conductive film on the second surface of the substrate to form a first group of sensing electrodes and a second group of sensing electrodes ; Wire production process, respectively in the first group of sensing electrodes and the peripheral area of ​​the second group of sensing electrodes screen printing metal paste and solidified, respectively forming the first group of external wires connected with the first group of sensing electrodes and the second group of connecting wires The second set of external leads to which the sense electrodes are connected. The manufacturing method of the capacitive touch screen can simplify the process, reduce the investment, reduce the unit price cost, and help to improve the rate of good products.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a method for manufacturing a capacitive touch screen, which is a method for realizing a capacitive touch screen that can simplify processes, reduce investment, and reduce unit cost. Background technique [0002] At present, as an input device, the touch screen allows users to directly input information by touching or handwriting on the surface of the display device with a touch screen. It is more friendly and convenient than input devices such as mouse and keyboard, so it is more and more widely used. On various portable devices (such as mobile phones, PDAs, etc.). There are many types of existing touch screen technologies, which can be divided into resistive, capacitive, infrared, surface acoustic wave, etc. according to the type of contact used and the method of confirming the position of the contact. With the maturity of capacitive control IC technology, the decline in cost, and ...
