Patent ID: 8610648

Claim:
A display device comprising a plurality of pixels, each comprising: a light-emitting element; a storage capacitor; a driving transistor which comprises a control terminal, an input terminal, and an output terminal and supplies a driving current to the light-emitting element to emit light; a first switching transistor which supplies a data voltage to the storage capacitor in response to an on-voltage of a scanning signal; a second switching transistor which diode-connects the driving transistor in response to an on-voltage of a compensation signal; a third switching transistor which supplies a driving voltage to the driving transistor in response to an on-voltage of a light emitting signal; a first light emitting signal line which transfers the light emitting signal to a first pixel of the plurality of pixels; a first compensation signal line which transfers the compensation signal to the first pixel; a second light emitting signal line which transfers the light emitting signal to the second pixel of the plurality of pixels; a second compensation signal line which transfers the compensation signal to the second pixel; and a light emitting driver which generates the light emitting signal, sequentially applies the light emitting signal to the first the second light emitting signal lines and generates the compensation signal and sequentially applies the compensation signal to the first and second compensation signal lines, wherein the storage capacitor stores a control voltage depending on a threshold voltage of the driving transistor when the driving transistor is diode-connected, transmits the control voltage and the data voltage to the control terminal of the driving transistor, a period in which the compensation signal is in an on-voltage state is longer than a period in which the scanning signal is in an on-voltage state, and is longer than about one horizontal period, and wherein the light emitting driver generates the compensations signal transferred to the second compensation signal line by inverting the light emitting signal transferred to the first light emitting signal line.
