Abstract
A driving circuit for a touch panel is disclosed. The driving circuit switches between a mutual capacitance sensing mode and a self capacitance sensing mode using the same sensing circuit. As such, the driving circuit for a touch panel implements a hybrid touch panel that is capable of sensing a touch in either a mutual capacitance sensing mode or a self capacitance sensing mode without requiring a complex and large driving circuit for separate sensing circuits for each mode.
