Patent attributes
The disclosure provides a touch display driving apparatus and an operation method thereof. The touch display driving apparatus is configured to drive a touch display panel. The touch display driving apparatus includes a touch sensing circuit configured to output a touch driving signal to a touch sensor array of the touch display panel, and receive touch sensing signals from the touch sensor array. The touch driving signal is configured to scan the touch sensor array at a normal scan rate in a normal touch scanning mode, and scan, in response to a touch event which is determined as occurring in a doze mode, the touch sensor array at a first scan rate in a fast touch scanning mode immediately preceding to the normal touch scanning mode, wherein the first scan rate is greater than the normal scan rate.
