Abstract
The present application discloses a pixel driving circuit. The circuit includes an input sub-circuit configured to set a voltage level at a first node; a storage sub-circuit coupled between the first node and a second node; and a drive sub-circuit coupled to the first node and the second node and configured to drive light emission of a light-emitting device. Additionally, the circuit includes a charge sub-circuit coupled to the drive sub-circuit, and configured to charge the drive sub-circuit to latch a voltage level at the second node to be larger than a first threshold but smaller than a second threshold. Furthermore, the circuit includes an adjust sub-circuit coupled to a second node and coupled to the input sub-circuit at least via the first node, and configured to at least adjust voltage level at the second node to make the light-emitting device with an inverted polarity in one partial period.
