Abstract:
A chip, an electronic device, a panel and an operation method thereof are provided. The chip can control the panel to perform fingerprint sensing. Fingerprint sensing pixels of the panel are divided into a plurality of fingerprint zones along a column direction. The chip includes a selecting circuit and a control circuit. The selecting circuit obtains information about a selected fingerprint zone among the fingerprint zones. The control circuit provides multiple control signals for controlling the panel to perform fingerprint sensing. The control signals include multiple start pulse signals. The start pulse signals collectively indicate the selected fingerprint zone. The number of the fingerprint zones is greater than the number of the start pulse signals.
