Problems solved by technology
Although this solution can take advantage of the simple process structure of the single-layer self-capacitance touch screen, realize multi-touch with low cost, and solve the problem of ghost points during capacitive multi-touch, but when the number of touch electrodes increases , it will cause the problem of too many electrode connecting wires
[0006] In view of this, how to improve the existing design scheme to solve the above-mentioned ghost point problem and the defect of too many electrode connecting lines in capacitive multi-touch, and to improve the convenience of the manufacturing process and the accuracy of touch positioning is an important issue. A subject to be solved urgently by relevant technicians in the industry

The invention provides an AMOLED display device of an integrated touch panel. The AMOLED display device comprises a pixel defining layer, a patterned metal layer and a spacer, wherein the pixel defining layer is used for defining a pixel area, the patterned metal layer is arranged on the pixel defining layer, one part of the patterned metal layer is used as a cathode of the AMOLED display device, the other part of the patterned metal layer is used as a touch electrode, and the spacer is arranged between the cathode and the touch electrode and used for electrically isolating the cathode from the touch electrode. Compared with the prior art, the cathode and the touch electrode of the AMOLED display device can be integrated into the same layer and are manufactured through the same manufacture procedure, and the manufacturing cost is reduced; In addition, by the adoption of the AMOLED display device of the integrated touch panel, a touch TFT can also be controlled, the capacitance change of each touch electrode with defined coordinates can be independently measured, and the ghost focus problem existing during capacitance multi-point touch can be eliminated due to the fact that the coordinate position obtained through measurement is the absolute coordinate position of a touch screen.
Description
technical field [0001] The present invention relates to an AMOLED display device, in particular to an AMOLED display device integrated with a touch panel. Background technique [0002] Organic light emitting diodes (Organic Light Emitting Diode, OLED) can be divided into passive matrix driving (Passive Matrix OLED, PMOLED) and active matrix driving (Active Matrix OLED, AMOLED) according to the driving method. PMOLED is that when the data is not written, the light-emitting diode does not emit light; only when the data is written, the light-emitting diode emits light. This driving method is simple in structure, low in cost, easy to design, and is mainly suitable for small and medium-sized displays. In AMOLED, each pixel has a capacitor to store data, so that each pixel maintains a light-emitting state. Since the power consumption of AMOLED is significantly lower than that of PMOLED, and its driving method is suitable for the development of large-size and high-resolution disp...
