Abstract:
Provided are a pixel circuit, a display panel and a display apparatus. The pixel circuit includes: a first resetting switching transistor, a first data writing switching transistor, a storage capacitor, a first compensation capacitor, a second compensation capacitor, and a driving transistor; the first resetting switching transistor includes a first switching sub-transistor and a second switching sub-transistor connected in series, and the first data writing switching transistor includes a third switching sub-transistor and a fourth switching sub-transistor connected in series. The first compensation capacitor and the second compensation capacitor are used to enable a voltage Vn1′ of the first node to be smaller than a voltage Vn3′ of the third node and larger than a voltage Vn4′ of the fourth node in a light-emitting stage.
