    摘要: The present disclosure provides a pixel driving circuit, a driving method thereof, and a display device. In one example, the pixel driving circuit includes: a driving transistor; a voltage holding sub-circuit, the first end of the voltage holding sub-circuit connected to the gate of the driving transistor; a data writing sub-circuit configured to supply a data voltage to the driving transistor when the first scanning line is at a first level, and connect the gate of the driving transistor and a second electrode; a converting sub-circuit configured to supply illumination power voltage to a second end of the voltage holding sub-circuit when the second scanning line is at the first level, and connect the second end of the voltage holding sub-circuit to the second end of the driving transistor when the third scanning line is at the first level; and a switch sub-circuit configured to supply illumination power voltage to the first end of the driving transistor when the third scanning line is at the first level, and connect the second end of the drive transistor to the current output end of the pixel drive circuit. The present disclosure can achieve threshold voltage compensation for the drive transistor.

    摘要: A thin film transistor array substrate includes a base substrate and a thin film transistor, a second insulation layer, a first electrode and a second electrode formed on the base substrate. The first electrode and the second electrode are used to form an electric field, and the second insulation layer is interposed between the first electrode and the second electrode. The second electrode is a comb-like electrode, and located at a side of the second insulation layer away from the base substrate. The array substrate further includes protrusion structure located at a side of the first electrode close to the base substrate, the position of the protrusion structure corresponds to the slit portions of the comb-like electrode. A manufacturing method of a thin film transistor array substrate and a display device are further provided.
