Problems solved by technology

[0004] Generally, the wiring of traditional thin-film capacitive touch screens is mostly made by screen printing, that is, a number of silver paste circuit traces are made on the substrate by screen printing technology, and the printing limit line width / line spacing is 80 μm / 80μm, and in actual production, it is easy to produce jagged and irregular lines, and the process stability is not good, which cannot meet the market's design requirements for narrow bezel touch screens

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 2 As shown, a manufacturing method of a touch screen sensing component in an embodiment includes the following steps:

[0027] Step S210, printing the photosensitive conductive material on the edge of the transparent electrode to form a bulk photosensitive conductive material as a whole. The photosensitive conductive material is printed on the edge of the transparent electrode. At this time, the photosensitive conductive material can be just in contact with the edge of the transparent electrode, or can cover a part of the edge of the transparent electrode. In this embodiment, the photosensitive conductive material covers a small portion of the edge of the transparent electrode 202 , so that the formed lead wire 208 is better connected to the transparent electrode 202 and improves the stability of the connection...

Abstract

The invention discloses a touch screen sensing component and a production method thereof. The production method includes the steps of printing a sheet of photosensitive conductive material on the side of a transparent electrode to obtain a photosensitive conductive sheet; and exposing the photosensitive conductive sheet to light under a photomask with a preset pattern, and developing to obtain an outgoing wire of the transparent electrode. The production method has the advantages that the outgoing wire is made of the photosensitive conductive material, the traditional printing is combined with exposure and development; and accordingly, fine lines are generated by the exposure and development, the complex process of metal film evaporation and etching and photoresist stripping is avoided, and the production cost of fine wires is reduced. The outgoing wires of the touch screen sensing component produced by the method are 30 micrometers / 30 micrometers in wire width / wire spacing, and the touch screen sensing component meets the design requirement of market for narrow-frame touch screens.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a touch screen sensing component and a manufacturing method thereof. Background technique [0002] Since the capacitive touch screen has a more intuitive human-computer interaction mode, it is widely used as an input terminal in mobile phones and tablet computers. With the increasing demand for the appearance and aesthetics of mobile phones and tablet computers (minimizing the frame and maximizing the window), the capacitive touch screen with narrow frame is slowly becoming a fashion design trend. [0003] The relationship between the frame of the capacitive touch screen and the wiring is as follows: figure 1 As shown, in the capacitive touch screen mobile phone 10, there are a plurality of wires 102 connected to the conductive patterns in the visible area of ​​the touch screen on the side of the frame 104. Therefore, in order to realize the narrowing of the frame of the capacitive ...
