Abstract
The present disclosure relates to a pixel circuit including a charging circuit, a driving circuit, a compensating circuit, an adjusting circuit and a light emitting device. In a charging stage, a first node and a second node may be charged through the charging circuit. In a compensating stage, a threshold voltage compensation is applied to the third node through the compensating circuit. In an adjusting stage, a potential of the third node is adjusted by the adjusting circuit. In a light emitting stage, the driving circuit drives the light emitting device to emit light through the first power signal under control of the third node. Meanwhile, a threshold voltage compensation is applied to the third node which controls the driving circuit during the compensating stage.
