Abstract
Provided is a pixel drive circuit including: a first transistor, configured to transmit a signal of a first power source voltage end to a first node in response to an enable signal of a light-emitting signal control end; a first drive transistor, configured to generate a drive current on a conduction path from the first node to a third node according to an enable signal of a second node, the first drive transistor being an N-type transistor; a second drive transistor, configured to generate a drive current on the conduction path from the first node to the third node according to an enable signal of the second node, the second drive transistor being a P-type transistor; and a second transistor, configured to transmit a signal of a polarity switching signal end to the second node in response to an enable signal of a first scan signal end.
