Abstract: A display device, an operation, a driving circuit and a timing control circuit are provided. The display device includes a touch display panel, the driving circuit and the timing control circuit. The driving circuit drives the touch display panel to display image frames and perform touch detection. The timing control circuit outputs display data to the driving circuit through a data transmission path during a display period to display the image frame on the touch display panel. The driving circuit outputs touch detection data corresponding to the touch detection to the timing control circuit through the same data transmission path during a touch detection period.
