Abstract
A pixel circuit including a constant current driver including a first driving transistor for controlling a current through a light-emitting element, a first electrode thereof being connected to a first power source, and a second electrode thereof being connected to an anode electrode of the light-emitting element, and an emission time controller including a second driving transistor between a second power source and the constant current driver, and configured to control the emission time by turning off the first driving transistor after a time at which a Pulse Width Modulation data voltage corresponding to an input image is applied to a gate electrode of the second driving transistor, and based on a magnitude of the PWM data voltage, wherein the second driving transistor is turned on based on the magnitude of the PWM data voltage, to transfer a driving voltage from the second power source to the constant current driver.
