Problems solved by technology

However, the manufacturing method of this kind of edge wiring circuit is easy to affect the uniformity of printing due to the physical properties of the silver paste material itself, and may cause poor flatness of the circuit and affect the signal output result.
In addition, the tension of the stencil and the number of printings will also affect the accuracy of the silver paste circuit
Therefore, the current method of making edge traces by screen printing process is easily limited by the properties of printing materials,

Abstract

The invention provides a manufacturing method for touch panel edge wire routing, a control panel with the edge wire routing and a touch display device. The manufacturing method comprises the following steps of (a) forming a photosensitive conductive paste layer on an edge area of a substrate with a transparent conductive layer, enabling the photosensitive conductive paste layer to be at least in partial overlapping with the transparent conductive layer, (b) exposing the photosensitive conductive paste layer by using a mask, and (c) carrying out developing on the exposed photosensitive conductive paste layer to form a patterning edge wire routing unit on the edge area of the substrate. The manufacturing method is beneficial to improving the precision of a wire route under the situation that the wire width of the edge wire routing is narrowed, and can enable the wire route to have good surface smoothness.

Description

technical field [0001] The invention relates to a method for manufacturing edge traces of a touch panel, in particular to a method for manufacturing edge traces of a touch panel capable of improving circuit accuracy, a touch panel with the edge traces, and a touch display device. Background technique [0002] With the popularization of smart phones, 3C devices with touch-operated interfaces and related technologies are booming, and the trend of thinner and lighter 3C devices also makes touch panels have higher and higher requirements for thinner. Among them, the projected capacitive touch panel (Projceted Capacitive Touch Panel, referred to as PCTP) has become the mainstream of the existing touch panel due to its lightness, thinness, anti-interference characteristics, and the use effect of real multi-touch. . Since the capacitive touch panel must be provided with edge wiring in a very thin edge area, the existing way of setting the edge wiring is to print the silver paste m...
