Abstract
The present disclosure provides a pixel driving circuit, a method for driving the pixel driving circuit, and a display panel. The pixel driving circuit includes: a driving circuit coupled to a first control signal terminal and a data signal terminal, and configured to generate a driving current based on a signal from the data signal terminal under control of a signal from the first control signal terminal; and a compensation circuit coupled to the first control signal terminal, a second control signal terminal, an output signal terminal, and the driving circuit, and configured to perform a threshold voltage compensation on the driving circuit and provide the driving current generated by the driving circuit to the output signal terminal, under control of a signal from a first control signal terminal and a signal from the second control signal terminal.
