Problems solved by technology

This structure is achievable for small-sized embedded self-capacitance touch screen products, but with the increase of touch electrode blocks, the surrounding wiring area will form a touch blind area, and the large width of the touch blind area is directly controlled by the touch panel. The number of sensors is determined, so this structure is not suitable for larger products

Abstract

The invention discloses an OLED touch display substrate, a manufacturing method thereof, a display panel and a display device. The OLED touch display substrate includes an anode on a substrate, a cathode, an organic light-emitting layer between the anode and the cathode, and a pixel defining layer with via holes; the cathode includes a plurality of mutually insulated sub-layers. The cathode, the plurality of sub-cathodes are multiplexed into a plurality of touch electrodes; the OLED touch display substrate further includes touch signal lines electrically connected to the touch electrodes through the via holes in one-to-one correspondence. The OLED touch display substrate is thin and has no touch blind area.

Description

technical field [0001] The invention relates to the technical field of touch display. More specifically, it relates to an OLED touch display substrate, a manufacturing method, a display panel and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is one of the hotspots in the field of flat panel display research. Compared with liquid crystal displays, OLED has the advantages of low energy consumption, self-illumination, wide viewing angle, fast response speed, and low production cost, so it has gradually replaced traditional LCD displays in the display fields of mobile phones, PDAs, and digital cameras. Among them, the design of pixel driving circuit is the core technical content of OLED display, which has important research significance. [0003] At present, most of the existing OLED-based touch products adopt the plug-in touch structure, that is, the touch panel is combined with the TFE packaging structure of the OLED display substrate to...
