PIXEL CIRCUIT, METHOD FOR DRIVING THE SAME, ARRAY SUBSTRATE AND DISPLAY DEVICE

摘要

The pixel circuit comprises a driving sub-circuit, a controlling sub-circuit and a light-emitting sub-circuit. The light-emitting sub-circuit includes a first organic light-emitting element and a second organic light-emitting element. The first and second organic light-emitting elements are coupled to the driving sub-circuit respectively. The controlling sub-circuit is coupled to the driving sub-circuit so as to control the driving sub-circuit to drive the first and second organic light-emitting elements, so that at an identical display stage, one of the first and second organic light-emitting elements emits light in a forward bias state and the other does not emit light in a backward bias state, and at an adjacent display stage, the bias states are switched.
