Patent ID: 8619006

Claim:
A display device comprising a plurality of pixels, each pixel including: a light emitting element; a capacitor; a driving transistor having a control terminal, an input terminal, and an output terminal which is connected to the light emitting element, the driving transistor for supplying a driving current to the light emitting element to emit light; a first switching unit comprising a first switching transistor for electrically connecting the control terminal and the input terminal of the driving transistor in response to a scanning signal; and a second switching unit supplying a driving voltage to the driving transistor and connecting the capacitor to the driving transistor both in response to an emission signal, wherein the capacitor is connected to the driving transistor through the first switching unit, stores a control voltage depending on the common voltage, the data voltage and a threshold voltage of the driving transistor, and is connected to the driving transistor through the second switching unit to supply the control voltage to the driving transistor.
