Abstract: A drive circuit applicable to a display device includes a first signal path and a second signal path. The first signal path, configured to receive image data and transmit the image data in a first operation mode, includes a compression unit, a storage unit and a de-compression unit. In the first operation mode, the compression unit performs a compression procedure on the image data to generate compression data, the storage unit stores the compression data, and the de-compression unit receives the compression data and performs a de-compression procedure on the compression data to recover the image data. The second signal path is configured to receive image data, transmit the image data to the storage unit so as to bypass the compression unit, and transmit the image data received from the storage unit to a display unit so as to bypass the decompression unit in a second operation mode.

Abstract: A fingerprint sensing control device and an operation method thereof are provided. The fingerprint sensing control device includes a touch control circuit and a fingerprint sensing control circuit. The touch control circuit determines a touched region of an object on the touch panel. The fingerprint sensing control circuit performs a fingerprint sensing control on the touch panel and determines a target sensing sub-region overlaid by the touched region from a plurality of sensing sub-regions of the fingerprint sensing region of the touch panel. When the target sensing sub-region comprises a first sensing sub-region and a second sensing sub-region that are adjacent to each other, the fingerprint sensing control circuit starts to scan the first sensing sub-region in a first direction from a common edge between the first sensing sub-region and the second sensing sub-region and starts to scan the second sensing sub-region in a second direction from the common edge.
