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 an embedded touch screen and a display device. With a bottom emission organic electroluminescence pixel structure, a self-capacitance electrode is arranged between a pixel unit and a lower substrate; a lead is arranged between the lower substrate and the organic electroluminescence pixel structure, so electric connection between the lead and a touch control electrode can be achieved without the organic electroluminescence pixel structure; technology manufacturing difficulty can be reduced; and production cost can be lowered.

Description

Technical field [0001] The invention relates to the technical field of touch display, in particular to an in-cell touch screen and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display is one of the hot spots in the field of flat panel display research today. Compared with liquid crystal display, OLED display has low energy consumption, low production cost, self-luminescence, wide viewing angle and fast response speed. Advantages. At present, OLED displays have begun to replace traditional LCD displays in the display fields of mobile phones, PDAs, and digital cameras. [0003] With the rapid development of display technology, touch screens (TouchScreenPanel) have gradually spread throughout people's lives. At present, touch screens can be divided into add-on touch screens (AddonModeTouchPanel), overlay surface touch screens (OnCellTouchPanel), and in-cell touch screens (InCellTouchPanel) according to their composition structure. Among them, t...
