Abstract
A pixel circuit, a display apparatus, and a driving method. The pixel circuit include: a driving circuit, a data writing circuit, a compensation circuit, a light emission control circuit, a first reset circuit, a second reset circuit, and a light-emitting element. The data writing circuit is for writing a data signal into the first terminal of the driving circuit based on a writing control signal; the first reset circuit is for applying a first reset voltage to the control terminal of the driving circuit based on a first reset control signal; and the second reset circuit is for applying a second reset voltage to a first electrode of the light-emitting element based on a second reset control signal. The writing control signal and the second reset control signal are synchronized in each write frame, and the writing control signal remains at an invalid level in each skip frame.
