Abstract
The present disclosure provides a pixel driving circuit and method thereof, a display driving circuit and method thereof, and a display panel. The pixel driving circuit includes: a first pixel driving sub-circuit configured to provide a driving signal to a driving signal output terminal in a first period and perform threshold voltage compensation on a second pixel driving sub-circuit in a second period under control of signals at a first scanning signal terminal, a first control signal terminal, and a first data signal terminal; and the second pixel driving sub-circuit configured to provide a driving signal to the driving signal output terminal in the second period and perform threshold voltage compensation on the first pixel driving sub-circuit in the first period under control of signals at a second scanning signal terminal, a second control signal terminal, and a second data signal terminal.
