Abstract

A touch display device and an operating method for the touch display device are provided. The touch display device includes a touch display panel, a touch display driving circuit and a computing circuit. The touch display driving circuit drives the touch display panel to perform a display operation based on a scan frequency and to perform a touch sensing operation based on a plurality of touch sensing cycles. The computing circuit determines a plurality of scan finishing positions on the touch display panel in response to the scan frequency and the touch sensing cycles, receives a touch sensing data corresponding to the scan finishing positions, and compensates the touch sensing data based on a base value.
