Abstract

A pixel control circuit and a control method thereof, and a display device. The pixel control circuit includes a control-signal output sub-circuit and a switch sub-circuit. An input terminal of the switch sub-circuit is electrically coupled to an output terminal of the control-signal output sub-circuit. An input terminal of the control-signal output sub-circuit is electrically coupled to a data line. The control-signal output sub-circuit is configured to: compare a voltage received by the data line with a reference voltage; and if a value of the voltage is equal to a value of the reference voltage, output a first control signal, otherwise output a second control signal. The switch sub-circuit is configured to be turned off under control of the first control signal and turned on under control of the second control signal. The reference voltage is a corresponding gamma voltage when the display panel is in a dark state.
