Abstract
A touch sensing and feedback apparatus comprises a feedback electrode, a reference electrode electrically insulated from the feedback electrode, a signal generator to generate a sensing driving signal and transmit the sensing driving signal to a sensing electrode, and a signal detector coupled to a detecting electrode to detect the sensing driving signal and generate a touch action signal based on the detected sensing driving signal. The signal generator generates a feedback driving signal and transmits the feedback driving signal to the feedback electrode based on the touch action signal, and generates a reference driving signal and transmits the reference driving signal to the reference electrode based on the touch action signal. The reference driving signal maintains the reference electrode electrically-grounded.
