Abstract:
The present disclosure discloses a pixel circuit, a display apparatus and a dual-gate driving transistor. The pixel circuit comprises a dual-gate driving transistor having a drain electrically connected to a first power supply terminal; a threshold voltage compensation unit electrically connected to a data terminal, a first control terminal, a first gate of the dual-gate driving transistor, and a source of the dual-gate driving transistor respectively; a mobility compensation unit electrically connected to a sensing signal terminal, a second control terminal, and the source of the dual-gate driving transistor respectively; and a light emitting control unit electrically connected to the data terminal, a third control terminal, a second gate of the dual-gate driving transistor, the source of the dual-gate driving transistor, and a light emitting device respectively. The threshold voltage compensation unit and the mobility compensation unit perform threshold voltage compensation for the dual-gate driving transistor under the control of the data terminal, the first control terminal, the sensing signal terminal, and the second control terminal; and the mobility compensation unit and the light emitting control unit perform mobility compensation for the dual-gate driving transistor and control the dual-gate driving transistor to drive the light emitting device to emit light under the control of the sensing signal terminal, the second control terminal, the data terminal, and the third control terminal.
