Embodiment Construction

[0032] Next, the technical solutions in the embodiments of the present invention will be apparent from the embodiment of the present invention, and it is clearly described, and it is understood that the described embodiments are merely embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0033] In the touch panel that needs to be connected to the touch electrode through the bridge, the cross-bridge electrode layer for the preparation of the bridge is a metal layer. A conventional process method for patterning the metal layer is dry etching, but since the cross-bridge electrode layer is formed into a bridge, the metal coverage of the cross-bridge electrode layer is low, and the entire touch panel corresponds to the entire touch panel. In the area, only the cross bridge of the partial region, and most areas a...

Abstract

The invention discloses a touch panel and its manufacturing method, a touch-integrated display panel, and a display device. In the technical solution of the invention, the bridge electrode layer is set to include a plurality of bridges and auxiliary conductive parts. Connecting the two adjacent touch electrodes in the two adjacent touch electrode layers, the metal coverage of the metal line of the bridge electrode layer can be increased through the auxiliary conductive part, thereby reducing or avoiding the risk of disconnection of the bridge and improving the product quality. yield rate.

Description

Technical field [0001] The present invention relates to the technical field of electronic devices, and more particularly to a touch panel and a display panel thereof, an integrated touch display panel, a display device. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with touch function are widely used in people's daily work and their lives, and bring huge convenience for people's daily lives and work, become today people. An indispensable tool for life. [0003] The main components of the electronic device implementation of the touch function are the touch panel. The touch panel detects the touch position via the touch electrode layer. In general, the touch electrode layer needs to be set to a particular electrode pattern, forming a plurality of touch electrodes, and a cross bridge prepared by another layer of conductive layer is electrically connected between the touch electrodes. [0004] In the existing...
