Abstract
A pixel circuit, driving method for same and display apparatus are provided. The pixel circuit includes a driving sub-circuit, writing sub-circuit, compensation sub-circuit, first reset sub-circuit, first and second emitting control sub-circuits, and emitting element. The compensation sub-circuit writes signal of third node into first node under control of third scanning signal terminal, and compensates first node under control of the third scanning signal terminal and first voltage terminal. The first reset sub-circuit writes signal of first initial signal terminal into third node under control of first scanning signal terminal and first emitting control signal terminal. The second emitting control sub-circuit provides signal of first voltage terminal for second node under control of second emitting control signal terminal. The first emitting control sub-circuit provides signal of third node for fourth node under control of the first emitting control signal terminal, allows driving current to flow between third and fourth nodes.
