Abstract
The present disclosure provides a pixel driving circuit, a display panel and methods for driving the same. The pixel driving circuit includes: at least two driving sub-circuits, each configured to generate driving current based on a compensated data signal; at least two light-emitting control sub-circuits coupled to the at least two driving sub-circuits respectively, each of the at least two light-emitting control sub-circuits is configured to output driving current generated by one of the at least two driving sub-circuit coupled thereto; a writing control sub-circuit electrically coupled to the at least two driving sub-circuits and a data writing sub-circuit; and the data writing sub-circuit configured to compensate for a data signal and write the compensated data signal into the at least two driving sub-circuits sequentially under control of the writing control sub-circuit.
