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.
