Patent ID: 8754834

Claim:
A display device comprising: a plurality of pixels, each pixel including a plurality of individual-color sub-pixels, each sub-pixel including an individual-color light emitting element and an emission control transistor; and emission control lines connected to the pixels and receiving control pulses to vary emission periods of the individual-color sub-pixels based on respective luminous efficiencies of the individual-color sub-pixels, wherein the individual-color sub-pixels include one of a first individual-color sub-pixel type including an emission control transistor of a first conductive type and a second individual-color sub-pixel type including an emission control transistor of a second conductive type different from the first conductive type, one emission control line is connected in common to at least one sub-pixel of each of the first and second individual-color sub-pixel types, and an emission-control-line drive circuit controls control pulses of the emission control lines such that each of the control pulses has a period comprising a plurality of sub-periods, in which both the emission control transistor of the first conductive type and the emission control transistor of the second conductive type are set to be on during respective first and second sub-periods of the plurality of sub-periods and are set to be off concurrently during a third sub-period of the plurality of sub-periods, wherein at least two different individual-color light emitting elements are set to be on concurrently during the first sub-period.
