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.

Abstract: A fingerprint sensor apparatus including a fingerprint sensor and a processor circuit is provided. The fingerprint sensor is configured to capture a plurality of local fingerprint images of a fingerprint. The plurality of local fingerprint images include at least one first local fingerprint image and at least one second local fingerprint image. The processor circuit is electrically connected to the fingerprint sensor. The processor circuit is configured to identify the fingerprint according to the at least one first local fingerprint image of the local fingerprint images. The local fingerprint images form a global fingerprint image of the fingerprint. In addition, a method for sensing a fingerprint is also provided.
