Abstract: A driver integrated circuit for fingerprint sensing, touch sensing and display driving and a driving method thereof are provided. The driver integrated circuit is adapted for driving a touch display panel with a fingerprint sensor. The driver integrated circuit includes a fingerprint sensing control circuit, a display driving circuit, and a display driving circuit. The fingerprint sensing control circuit drives the fingerprint sensor to perform a fingerprint sensing operation. The display driving circuit drives the touch display panel to perform a display operation. The touch sensing control circuit drives the touch display panel to perform a touch operation. The fingerprint sensing control circuit and the display driving circuit have a first direct communication therebetween so as to facilitate at least one of the fingerprint sensing operation and the display operation.

Abstract: A display device, a multi-fingerprint detection device and an operation method thereof are provided. The multi-fingerprint detection device includes a touch circuit and a fingerprint sensing control circuit. The touch circuit performs touch detection control on a touch panel module to determine a plurality of touch regions of a touch event on the touch panel module. The fingerprint sensing control circuit performs fingerprint sensing control on the touch panel module, so that the touch panel module senses a plurality of target sub-regions corresponding to the touch regions, and then obtains fingerprint sensing result of the target sub-regions. The fingerprint sensing control circuit divides the fingerprint sensing result into a plurality of sub-fingerprint images according to the touch regions.
