Problems solved by technology

The traditional In Cell Touch technology has not yet been applied to AMOLED technology, because there is a layer of cathode metal electrode on the AMOLED panel that covers the entire surface. Tx) and touch sensing line (Rx) have a signal shielding effect, so it is impossible to realize the In-Cell Touch design in the AMOLED structure

Abstract

The present invention provides an embedded touch AMOLED panel structure, including a TFT substrate and an OLED touch layer disposed on the TFT substrate, the OLED touch layer includes an anode conductive layer, a pixel definition layer, a light emitting layer, and a cathode conductive layer , an insulating layer, and a bridging layer; the cathode conductive layer includes a plurality of parallel cathode strips, a plurality of parallel touch sensing lines, and a plurality of array-arranged touch scanning electrode blocks, and the bridging layer includes a row of touch The bridging line connecting the control scanning electrode block in series, the present invention avoids the signal from the OLED cathode layer to the embedded touch sensor in the traditional AMOLED panel by dividing and setting the cathode strip, the touch sensing line and the touch scanning electrode block in the same layer. The shielding effect realizes the true embedded touch technology in the AMOLED panel, and also simplifies the product structure and greatly reduces the thickness of the product, which can be applied to the technical requirements of integrating ultra-thin display and flexible display.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to an embedded touch AMOLED panel structure. Background technique [0002] With the rapid development of display technology, touch screens have become popular in people's daily life. For example, users can directly operate programs, input messages / Text / pattern, saving the trouble of using input devices such as keyboards or keys. Actually, the touch screen usually has a sensing panel. The electronic device judges the meaning of the touch according to the position touched by the user on the sensing panel and the picture displayed on the display at that time, and executes the corresponding operation result. [0003] Touch display panels can be divided into four types according to different sensing technologies: resistive, capacitive, optical, and acoustic. At present, the mainstream touch technology is capacitive, and capacitive is divided into self-capacitive and mutu...
