Abstract
A pixel circuit, a driving method and a display apparatus are provided. The pixel circuit includes: a signal input sub-circuit, a data input sub-circuit, a light emitting control sub-circuit, a compensation sub-circuit, a capacitor sub-circuit, a driving transistor and a light emitting device. By the cooperation of the above sub-circuits and elements, a threshold voltage of the driving transistor can be compensated, and a voltage of a first power terminal can also be compensated.
