Abstract

The invention discloses a touch control module, a manufacture method and a display device thereof, after forming the amorphous first transparent conductive layer, and prior to pattern etching of the metal layer, adding a step of forming a pattern of the first insulating layer on the pattern of the first transparent conductive layer. The first insulating layer is used to protect the first transparent conductive layer, so that the amorphous low-square-resistance first transparent conductive layer is avoided from being exposed to APC etching solution in large area, which causes the non-uniform erosion of the first transparent conductive layer, and the square-resistance of the first transparent conductive layer is avoided from being raised and the defect of Mura is avoided. And the pattern ofthe first insulating layer is designed for digging holes at bridges between the touch electrodes and at bridges between the touch electrodes and the lap terminals, furthermore, the characteristics ofAPC attacking the first transparent conductive layer 0 with low square resistance can be utilized to erode the bridge into a spherical surface, increasing the overlap area and reduce the contact resistance of the bridge, so as to realize the touch control product design with low square resistance on the flexible substrate.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular to a touch module, a manufacturing method thereof, and a display device. Background technique [0002] At present, in order to improve the electrical characteristics of touch screens in flexible touch screens, it is necessary to form amorphous indium tin oxide on a flexible substrate. Its film quality is unstable and is susceptible to advanced process control (APC) for flexible metals. The attack of the medium etching solution causes the increase of ITO square resistance, uneven ITO erosion, uneven ITO film thickness, and uneven brightness of the product appearance display (Mura). Summary of the invention [0003] In view of this, the embodiments of the present invention provide a touch module, a manufacturing method thereof, and a display device, to solve the problem that the amorphous ITO in the existing flexible touch screen is easily attacked by the APC etching solution a...
