Abstract
A display panel includes pixel circuits, first shift register(s), second shift register(s), third shift register(s), and fourth shift register(s). A pixel circuit includes a driving transistor, a bias sub-circuit, a data writing sub-circuit, a compensation sub-circuit, a leakage prevention sub-circuit, a reset sub-circuit, and a light-emission control sub-circuit. The bias sub-circuit is electrically connected to a first shift register, which transmits a first scanning signal to the bias sub-circuit. The data writing and compensation sub-circuits are electrically connected to a second shift register, which transmits a second scanning signal to the data writing and compensation sub-circuits. The leakage prevention sub-circuit is electrically connected to a third shift register, which transmits a third scanning signal to the leakage prevention sub-circuit. The light-emission control sub-circuit is electrically connected to a fourth shift register, which transmits a fourth scanning signal to the light-emission control sub-circuit.
