Abstract

A display device, an operation method, 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.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a display device and its operating method, a driving circuit and a timing control circuit. Background technique [0002] Touch display panels are often used in various electronic devices. In addition to the display function, the touch display panel can also provide a touch detection function. The timing controller can output the display data to the display driving circuit through the first group of data transmission paths, and then the display driving circuit can drive the touch display panel according to the display data to display image frames on the touch display panel. The touch driving circuit can drive the touch display panel for touch detection. The touch driving circuit may output touch detection data corresponding to the touch detection to a micro control unit (MCU) via a second group of data transmission paths (different from the first group of data transmission pat...
