Apparatus and method for driving fingerprint sensing array provided in touchscreen, and driver integrated circuit for driving the touchscreen including the fingerprint sensing array
Provided are a fingerprint controller for driving a fingerprint sensing array in a touchscreen divided by at least a touch sensing region and a fingerprint sensing region, a method of operating the fingerprint controller, and a driver integrated circuit for driving the touchscreen including the fingerprint sensing array. The method includes: receiving a reference timing signal from an external module; generating a fingerprint sensing timing signal for driving the fingerprint sensing array in synchronization with the reference timing signal; and driving the fingerprint sensing array based on the fingerprint sensing timing signal.
