Abstract
Provided are a pixel driving circuit, a method for driving the pixel driving circuit, a silicon-based display panel and a display device. The pixel driving circuit is used for driving a light-emitting element to emit light. At an initial stage, a reset circuit provides a reset signal to a third node; a light emission control transistor is in a first on state to transmit the reset signal to a second node; a threshold compensation circuit transmits the reset signal to a first node; and a data write circuit transmits a non-enable level Vofs of a data signal to a second terminal of a first capacitor. At a threshold compensation stage, the threshold compensation circuit provides a threshold voltage of a drive transistor to the first node for compensation.
