Abstract

The present invention provides a touch display substrate, a manufacturing method thereof, and a display device. The manufacturing method includes: forming a touch electrode trace, and the touch electrode trace is located in the display area of ​​the touch display substrate; forming an anode and an organic layer; forming a plurality of mutually insulated cathodes, the cathodes are multiplexed as touch electrodes, and the cathodes pass through the via holes on the film layer between the cathodes and the touch electrode wirings, and are connected with the touch electrodes The touch electrodes are wired, and the via holes are located in the display area of ​​the touch display substrate. In the present invention, the touch electrode wiring and the cathode that is multiplexed as the touch electrode are arranged in different layers, and are connected through the vias arranged in the display area. Since the layer where the cathode is located does not need to deploy the touch electrode wiring, it can improve The area occupied by the cathode can avoid touch blind areas and improve touch performance.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display devices are one of the hotspots in the field of flat panel display device research today. Compared with liquid crystal display devices, OLED display devices have low energy consumption, low manufacturing cost, self-illumination, and wide viewing angles. At present, OLED display devices have begun to replace traditional liquid crystal display devices in display fields such as mobile phones, PDAs (Personal Digital Assistant, PDA for short), and digital cameras. [0003] At the same time, as an in-cell touch (In Cell Touch) technology with relatively large technical difficulties, it is more and more favored by panel manufacturers because of its compatibility with the display panel process. Many companies also list the dev...
