Pixel driving circuit, display panel and driving method

Abstract

Provided are a pixel driving circuit, a display panel and a driving method. The pixel driving circuit includes: a driver transistor, a light-emitting device, a compensation capacitor, a threshold compensation sub-circuit, a data writing sub-circuit, a conduction control sub-circuit and a light-emitting control sub-circuit. The threshold compensation sub-circuit, in response to a signal at the compensation signal terminal, provides the threshold voltage of the driver transistor to the first end of the compensation capacitor; the conduction control sub-circuit, in response to the signal at the conduction control terminal, establishes the conducting path between the power signal terminal and the second end of the compensation capacitor; and the light-emitting control sub-circuit, in response to the signal at the light-emitting control signal terminal, provides the drive current generated by the driver transistor to the light-emitting device.
