Problems solved by technology

However, when forming the above-mentioned touch panel, since the signal lead layer is bonded to the printed circuit board through conductive glue, the signal leads on the signal lead layer may be crushed during the lamination process, which may cause the electrode layer to be separated from the printed circuit board. Problems such as the failure of the board to conduct, affect the stability of the electrical connection between the signal lead layer and the flexible circuit board in the touch panel, and then affect the yield of the product

Abstract

The invention provides a touch panel with a conductive protection layer. The touch panel with the conductive protection layer is characterized in that the touch panel comprises a substrate, a sensing electrode layer, a signal lead layer and a conductive protection layer, wherein a joint area is defined on the substrate, the sensing electrode layer is arranged on the substrate, the signal lead layer is arranged on the substrate and comprises multiple signal leads, one end of each signal lead is electrically connected to the sensing electrode layer, the other end of each signal lead is gathered to the joint area, the conductive protection layer comprises multiple conductive blocks, each conductive block is located on the corresponding signal lead in the joint area, and the signal leads are electrically insulated with one another. The invention further provides a manufacturing method of the touch panel with the conductive protection layer. The touch panel and the manufacturing method aim to solve the problem that signal leads are prone to fracturing when being attached to a flexible printed circuit in the prior art, and the product yield is increased.

Description

technical field [0001] The present invention relates to touch technology, and in particular to a touch panel with a conductive protective layer and a manufacturing method thereof. Background technique [0002] With the evolution of touch technology (Touch control), touch panels have been widely used in various consumer electronic devices, such as: smart phones, tablet computers, cameras, e-books, MP3 players and other portable electronic devices. products, or display screens applied to operator control equipment. [0003] A touch panel generally includes a substrate, an electrode layer, and a signal lead layer electrically connecting the electrode layer to a printed circuit board. However, when forming the above-mentioned touch panel, since the signal lead layer is bonded to the printed circuit board through conductive glue, the signal leads on the signal lead layer may be cracked during the lamination process, which may cause the electrode layer to be separated from the pr...
