Abstract

A touch apparatus and a touch detection integrated circuit (IC) thereof are provided. The touch detection IC includes a driving signal generation circuit and a receiving circuit. The driving signal generation circuit is configured to control a touch panel to perform touch sensing operation and control a fingerprint sensor to perform fingerprint sensing operation. The receiving circuit receives and processes a touch signal of the touch panel during a first period when the driving signal generation circuit transmits the first driving signal for controlling the touch panel to perform touch sensing operation. The receiving circuit receives and processes a fingerprint signal of the fingerprint sensor during a second period when the driving signal generation circuit transmits the second driving signal for controlling the fingerprint sensor to perform fingerprint sensing operation.
