Abstract
A pixel circuit, a driving method thereof, and a display device. The pixel circuit includes a light emission time control circuit, a current control circuit, and a light emission circuit. The light emission time control circuit includes a first drive circuit, a coupling circuit, and a first voltage write circuit. The first voltage write circuit is configured to transmit a fixed voltage to a control terminal of the first drive circuit. The coupling circuit is connected to the control terminal of the first drive circuit. A first terminal of the first drive circuit outputs a control voltage to a control terminal of the current control circuit. An output of the current control circuit is connected to the light emission circuit.
