  • Publication number: 20170076646
    Abstract: A display device includes a first pixel including a first light emitter, a second pixel including a second light emitter, and a holding capacitor connected to the first and second pixels. The holding capacitor stores first data for the first light emitter and stores second data for the second light emitter at different times. An irradiation direction of first light emitted by the first OLED is substantially equal to an irradiation direction of second light emitted by the second OLED. The first light from the first OLED is emitted in a first frame period and the second light from the second OLED is emitted in a second frame period to prevent mixing of the first and second light.
