Abstract
A pixel circuit includes a current control sub-circuit, a combined light emitting sub-circuit, and a first light emitting element to an Nth light emitting element, N being a natural number greater than 1. The current control sub-circuit is configured to receive a display data signal and a light emitting control signal, control whether to generate a driving current according to the light emitting control signal, and control a current intensity of the generated driving current according to the display data signal. The combined light emitting sub-circuit is configured to receive the driving current and a first light emitting data signal to an Nth light emitting data signal and drive one or more of the first light emitting element to the Nth light emitting element to emit light according to the first light emitting data signal to the Nth light emitting data signal.
