Pixel circuit, pixel driving method and organic light-emitting diode display device
A pixel circuit includes a data write-in circuit, a voltage amplification circuit, an energy storage circuit, a driving circuit and a light-emitting element. The driving circuit includes a control end, a first end and a second end. The voltage amplification circuit is connected to a data write-in node and the control end of the driving circuit, and configured to amplify a data voltage to acquire a driving voltage, and output the driving voltage to the control end of the driving circuit. The energy storage circuit is connected to the control end of the driving circuit. The first end of the driving circuit is connected to a power source voltage end, and the second end of the driving circuit is connected to an anode of the light-emitting element. The driving circuit is configured to control the power source voltage end to be electrically connected to, or electrically disconnected from, the anode of the light-emitting element under the control of the control end. A cathode of the light-emitting element is connected to a cathode voltage end.
