Abstract

The invention provides an embedded touch control AMOLED (Active-matrix Organic Light Emitting Diode) panel structure. The embedded touch control AMOLED (Active-matrix Organic Light Emitting Diode) panel structure includes a TFT substrate and an OLED (Organic Light Emitting Diode) touch control layer disposed on the TFT substrate; the OLED touch control layer includes an anode conductive layer, a pixel definition layer, a light-emitting layer, a cathode conductive layer, an insulating layer and a bridging layer; the cathode conductive layer comprises a plurality of parallel cathode strips, a plurality of parallel touch control sensing lines and a plurality of arrayed touch control scanning electrode blocks; and the bridging layer includes bridging lines which are used for connecting each row of touch control scanning electrode blocks in series. According to the embedded touch control AMOLED (Active-matrix Organic Light Emitting Diode) panel structure of the invention, the cathode strips, the touch control sensing lines and the touch control scanning electrode blocks are arranged in the same layer in a split manner, and therefore, a signal shielding effect exerted on an embedded touch control sensor by an OLED cathode layer in a conventional AMOLED panel can be avoided, and therefore, a real embedded touch control technology is realized in the AMOLED panel, the structure of a product can be simplified, the thickness of the product can be greatly reduced, and a technical requirement for integrating ultra-thin display and the flexible display can be satisfied.

Description

Technical field [0001] The present invention relates to the technical field of touch display, in particular to an in-cell touch AMOLED panel structure. Background technique [0002] With the rapid development of display technology, touch screens have become popular in people’s daily lives. For example, through the touch screen, users can directly use their fingers or stylus to operate programs and input information on the screen. Text / pattern, save the trouble of using keyboard or keys and other input devices. In fact, the touch screen usually has a sensor panel. The electronic device judges the meaning of the touch according to the position touched by the user on the sensor panel and the screen presented by the display at that time, and executes the corresponding operation result. [0003] Touch display panels can be divided into resistive, capacitive, optical, and sonic types according to different sensing technologies. The current mainstream touch technology is capacitive, and...
