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 for the substrate, a display panel and a display apparatus. The OLED touch display substrate comprises a positive electrode and a negative electrode located on a substrate, an organic luminous layer located between the positive electrode and the negative electrode, and a pixel definition layer provided with via holes;the negative electrode comprises multiple sub-negative electrodes insulated mutually; the sub-negative electrodes are multiplexed as touch electrodes; and the OLED touch display substrate further comprises touch signal lines electrically connected with the touch electrodes through the via holes in a one-to-one correspondence manner. The OLED touch display substrate is small in thickness and free of a 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...
