1. A chip capable of controlling a panel to perform fingerprint sensing, wherein the panel comprises a plurality of fingerprint sensing pixels and a plurality of gate lines arranged along a first direction of the panel for controlling the fingerprint sensing pixels, the fingerprint sensing pixels are divided into a first number of fingerprint zones along a second direction of the panel, and the chip comprises:
a control circuit, configured to provide a plurality of control signals to the panel for controlling the panel to perform fingerprint sensing, wherein the control signals comprise a second number of start pulse signals used to indicate a selected fingerprint zone, the first number is greater than the second number, and the second number of the start pulse signals are used to be provided to a decoder disposed on the panel, and the decoder determines the selected fingerprint zone according to logic values of the second number of the start pulse signals.
