Touch panel and display screen integrated OLED display device

The invention discloses a touch panel and display screen integrated OLED display device, which comprises an anode substrate and an encapsulation cover plate which are stuck and connected and functional layers which are arranged in turn between the anode substrate and the encapsulation cover plate, wherein the inner surface of the encapsulation cover plate of the display is provided with touch functional layers, and the touch functional layers comprise a first transparent electrode layer, a first transparent electric insulating layer, a second transparent electrode layer and a second transparent electric insulating layer which are arranged in turn on the inner surface of the encapsulation cover plate; and the first transparent electrode layer, the first electric insulating layer and the second transparent electrode layer form a flat capacitor array. The touch sensing functional layers are integrated on the encapsulation cover plate, so display and touch functions can be realized without sticking a touch module to the exterior of the display screen, and the structure of the device is more compact and favorable for reducing the appearance size and weight of the device.
