Abstract

See full text

A pixel driving circuit and a display panel are provided. The pixel driving circuit includes a control unit to output a control signal by detecting a voltage difference between two opposite ends of a sampling resistor, and to turn on a fourth switch by the control signal. When the fourth switch is turned on, a second positive voltage received by the pixel driving circuit charges a second node to further speed up a voltage pulling up of the second node to improve a detecting speed of the pixel driving circuit.
