Problems solved by technology

At the same time, the cathode layer 43 is multiplexed as a self-capacitance electrode, but because the respective capacitor electrodes need to be connected to the peripheral circuit through the wire 5, in order to reduce the mask (Mask) process, the wire 5 and the electrode in the pixel circuit 3 (specific structure figure 1 (not shown in ) are prepared on the same layer, which leads to the fact that the wire 5 needs to penetrate through the multi-layer film layers such as the organic light-emitting layer 42 and the anode layer 41 to be electrically connected to the cathode 43 that is reused as a self-capacitance electrode, resulting in a relatively difficult process. And the production cost is relatively high

Abstract

The invention discloses a built-in touch screen and a display device, adopting a bottom-emitting organic electroluminescent device, and setting a self-capacitance electrode between a pixel unit and a lower substrate, and setting a wire between the lower substrate and the organic electroluminescence Between the devices, the electrical connection between the wire and the touch electrode does not need to run through the organic electroluminescent device, thereby reducing the difficulty of manufacturing the process and further reducing the production cost.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to an embedded touch screen and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display is one of the hotspots in the field of flat panel display research today. Compared with liquid crystal display, OLED display has low energy consumption, low production cost, self-illumination, wide viewing angle and response At present, OLED displays have begun to replace traditional LCD displays in display fields such as mobile phones, PDAs, and digital cameras. [0003] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. Currently, touch panels can be classified into: Add on Mode Touch Panel, On Cell Touch Panel, and In Cell Touch Panel according to their composition and structure. Among them, the plug-in touch screen is produced separately from the touch screen and the d...
