TOUCH CONTROLLER FOR DRIVING TOUCHSCREEN INCLUDING FINGERPRINT SENSING ARRAY, DRIVING INTEGRATED CIRCUIT, AND OPERATING METHOD OF TOUCHSCREEN DEVICE INCLUDING SAME

摘要

Disclosed are a touch controller for driving a touchscreen including a fingerprint sensing array, a driving integrated circuit, and an operating method of a touchscreen device including the same. According to a technical idea of the present invention, the touch controller for sensing touch on the touchscreen including a touch sensing array and the fingerprint sensing array comprises: a touch sensing circuit for receiving a first sensing signal from the touch sensing array and generating first touch data on the basis of the first sensing signal; and a processor for calculating touch coordinates on the basis of a second touch data generated based on a second sensing signal provided from the fingerprint sensing array and the first touch data.;COPYRIGHT KIPO 2019
