Touch display driving apparatus and operation method thereof

The touch display driving apparatus according to claim further comprising:

• a control circuit, coupled to the touch sensing circuit to receive touch sensing information which is generated by the touch sensing circuit according to the plurality of touch sensing signals, and configured to generate a touch coordinate based on the touch sensing information.

An operation method of a touch display driving apparatus, comprising:

• outputting, by a touch sensing circuit, a touch driving signal to a touch sensor array of a touch display panel, wherein 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 the normal touch scanning mode, wherein the first scan rate is greater than the normal scan rate;
• and
• receiving, by the touch sensing circuit, a plurality of touch sensing signals from the touch sensor array, wherein the touch driving signal is further configured to scan the touch sensor array at a second scan rate in the doze mode to determine whether the touch event occurs, wherein the second scan rate in the doze mode is greater than the normal scan rate.
