Abstract: A display device includes a substrate including a display region, a first non-display region in the display region and a second non-display region outside the display region. A pixel array layer is disposed on the display region of the substrate. An encapsulation layer is disposed on the display region. The encapsulation layer is disposed on the first and second non-display regions of the substrate. The first non-display region includes a through hole penetrating the pixel array layer and the substrate. An encapsulation groove is spaced apart from the through hole. An inner wall of the through hole and an inner wall of the encapsulation groove are at least partially covered with the encapsulation layer. An end face of the encapsulation layer facing away from the pixel array layer has an irregular shape when viewed from a side of the substrate opposite the pixel array layer.

Abstract: A driving circuit includes a sensor driver and a display driver. The sensor driver outputs a touch signal, and the display driver receives a first interface signal from a processor and outputs a feedback signal to the processor. The feedback signal is output when a first frequency of the first interface signal and a second frequency of the touch signal received from the sensor driver match. The third frequency is different from the first frequency.
