Abstract:
A pixel circuit and a display device are provided. The pixel circuit includes: a first inverter circuit having an input terminal connected to a first node and an output terminal connected to a second node; a second inverter circuit having an input terminal connected to the second node and an output terminal connected to a third node; a first switching circuit configured to disconnect a connection between the first node and the third node when a first scanning signal is at an active level; and a control circuit configured to control a level of at least one of the first node and the second node according to a level control signal when the first scanning signal is at an active level. Based on this, it can help to avoid the output signal abnormality of the latch inside the pixel and enhance the working stability of the pixel circuit.
