AI Technical Summary

Problems solved by technology

[0004] However, conventional indium tin oxide is thin and fragile, and is prone to cracks during the manufacturing process, such as thermal expansion and contraction due to changes in etching temperature during the manufacturing process, or cracks due to electrostatic breakdown, thereby increasing oxidation. The resistance value of the indium tin line reduces the transmission efficiency of the sensing signal. In severe cases, an open circuit may occur, causing the touch panel to fail to move, especially the Y-axis line on the insulating layer, because the line itself is thin and It needs to straddle the insulating layer, which is more prone to local fracture or open circuit

Abstract

A touch panel is provided. The touch panel includes a substrate, a sensing-electrode layer and at least a metallic-patterned component disposed thereon. The electrode-sensing layer includes at least a first electrode axis arranged along a first axis, at least a second electrode axis arranged along a second axis, and an isolation layer. The second electrode axis includes a plurality of conductive units and conductive traces. The conductive units are arranged on two sides of the first electrode axis. The conductive traces electrically connect adjacent conductive units. The isolation layer is disposed between the conductive traces and the first electrode axis. The metallic-patterned component is electrically in contact with the respective conductive trace. The resistance of the metallic-patterned component is greater than the resistance of the conductive trace. The present disclosure strengthens the conductivity of the conductive trace by the placement of the metallic-patterned component.

Description

technical field [0001] The present invention relates to a touch technology, and in particular to a touch panel and a manufacturing method thereof. Background technique [0002] In recent years, with the development of touch panel technology, touch panels have been widely used in various electronic devices, such as mobile phones, laptop computers, and palmtop computers. A touch panel (touch panel) is generally integrated with a display panel (display panel) to form a touch display screen, which is used as an input and output interface of an electronic device to achieve a touch display function. Accordingly, the user can control the electronic device by touching the touch display screen with a finger or a touch-sensing object (such as a stylus), corresponding to the function of controlling the electronic device. Conventional touch input methods for touch panels include resistive, capacitive, optical, electromagnetic and acoustic induction, among which capacitive is a common t...
