Abstract
The invention relates to a pixel circuit, a driving method thereof, a display substrate and a display apparatus. The pixel circuit includes a first node control sub-circuit, a second node control sub-circuit, a light emitting control sub-circuit and a drive sub-circuit. The first node control sub-circuit is configured to supply a signal of the initial signal terminal to the first node and the fourth node under the control of the first reset signal terminal and the second scan signal terminal, and supply a signal of the second node to the first node under the control of the third scan signal terminal. The second node control sub-circuit is configured to supply a signal of the reference signal terminal to the second node and a signal of the data signal terminal to the third node under the control of the second reset signal terminal and the first scan signal terminal.
