Abstract

Disclosed are a pixel circuit, a driving method thereof, and a display apparatus. The pixel circuit includes a driving sub-circuit, a writing sub-circuit, a compensation sub-circuit, a reset sub-circuit, and a light-emitting element, the driving sub-circuit provides a driving current to a third node in response to a control signal of a first node; the writing sub-circuit writes a signal of a data signal line to a second node in response to a control signal of a first scan signal line, the signal of the data signal line is a data voltage signal or a reset voltage signal; the compensation sub-circuit writes the reset voltage signal to the third node in response to a control signal of the first scan signal line; the compensation sub-circuit further compensates the first node in response to a control signal of the first scan signal line.
