Touch sensing apparatus and touch sensing method thereof

A touch sensing method, configured to a touch sensing apparatus comprising a touch sensing panel;

• the touch sensing method comprising:
• in a sensing duration, switching to an operation mode among a plurality of operation modes;
• in the operation mode, receiving a plurality of driving signals, and sensing a touch event according to the driving signals;
• in the sensing duration, switching to another operation mode among a plurality of operation modes;
• in the another operation mode, receiving the driving signals, and sensing the touch event according to the driving signals;
• and
• determining a type of the touch event according to sensing results of the operation mode and the another operation mode.

A touch sensing apparatus, comprising:

• a touch sensing panel, comprising:
• a plurality of sensing channels, configured to receive a plurality of driving signals in an operation mode and sense a touch event according to the driving signals;
• and
• a touch controller, configured to determine the type of the touch event according to a sensing result of the sensing channels in the operation mode,
• wherein in the operation mode, the driving signals are a plurality of pulse signals, and at least one pulse signal among the pulse signals is different from rest pulse signals among the pulse signals.
