An electronic circuit adapted to control an operation of a gate driver circuit is provided. The electronic circuit includes a gate control circuit. The gate control circuit outputs control signals to the gate driver circuit in a display period and a fingerprint sensing period via the same output nodes. The control signals include a start pulse signal and a switch control signal. The switch control signal controls the gate driver circuit to operate in the display period or the fingerprint sensing period. The gate driver circuit includes a plurality of shift register groups and a switch circuit. The shift register groups output scan signals according to the start pulse signal. The switch circuit receives and outputs the scan signals to display scan lines in the display period and outputs the scan signals to fingerprint scan lines in the fingerprint sensing period according to the switch control signal.
An electronic circuit, adapted to control an operation of a gate driver circuit, wherein the gate driver circuit is disposed on a display panel, the electronic circuit comprising:
A gate driver circuit, wherein the gate driver circuit is disposed on a display panel, and the display panel comprises a plurality of display scan lines and a plurality of fingerprint scan lines, the gate driver circuit comprising:
