Abstract
A pixel circuit including a compensation circuit, a writing circuit, a light emitting element, and a power supplying circuit is provided. The compensation circuit comprises a first node, and provides a driving current to the light emitting element according to a voltage of the first node and a system high voltage. The writing circuit provides a data voltage to the compensation circuit according to a first control signal so that the compensation circuit sets the voltage of the first node. The power supplying circuit selectively couples the compensation circuit to the light emitting element, and provides the system high voltage and a system low voltage to the compensation circuit, in which the system low voltage is configured to reset the voltage of the first node. The first control signal and the second control signal are opposite to the first emission signal and the second emission signal, respectively.
