Patent ID: 8913054

Claim:
A display device, comprising: a plurality of drive circuits disposed in a matrix form; a plurality of display control lines, each connected to at least one of the plurality of drive circuits; and a plurality of shift registers being configured to shift an input pulse inputted thereto, and to thereby output a plurality of output signals, wherein each of the plurality of drive circuits includes a write transistor, a drive transistor, a first switching transistor, a capacitor portion, and a light emitting portion, such that in each of the plurality of drive circuits: the write transistor is configured to supply a data potential to the capacitor portion via the write transistor and the drive transistor, the drive transistor is configured to supply a drive current from a voltage line to the light emitting portion via the drive transistor and the first switching transistor, the magnitude of the drive current corresponding to the data potential, the first switching transistor is configured to switch between a display state and a non-display state according to one of the plurality of output signals, the respective first switching transistors of the plurality of drive circuits switch between the display state and the non-display state in a line-sequential manner, and a duration of the display state of the first switching transistor of each of the plurality of drive circuits is variably controlled by changing a width of the input pulse.
