Abstract
A fingerprint detection control circuit, a fingerprint detection control method and a display device. The fingerprint detection control circuit includes a sensing circuitry, a resetting circuitry, a control circuitry and a conversion circuitry. The control circuitry provides a switch control signal to a control end of the resetting circuitry under the control of a first control signal. The resetting circuitry provides a resetting voltage to a conversion control end under the control of a potential at its control end. The conversion circuitry converts a photovoltage signal into a corresponding current signal under the control of a potential at the conversion control end when a first voltage end is electrically connected to a first signal output end, and outputs the current signal via the first signal output end.
