Abstract
The present disclosure provides a pixel driving circuit, a driving method, a display panel and a display device. The pixel driving circuit comprises a plurality of signal splitting systems which include a scanning signal input interface configured to receive an original scanning signal with a width of MT, an auxiliary control signal input interface configured to receive an auxiliary control signal, and signal output interfaces connected to M rows of gate lines in an one-to-one correspondence manner. The signal splitting system is configured to split the original scanning signal with a width of MT into M gate driving signals with a width of a gate line turn-on time T, and output the gate driving signals to the M rows of gate lines sequentially via the output interfaces. M is not less than 2.
