  • Patent number: 10026344
    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.

  • Patent number: 9651862
    Abstract: Imprint lithography methods that incorporate depositing droplets of polymerizable material in patterns that improve fill time performance when employing directionally-oriented imprint templates. The patterns are based on grid arrays formed of repeating sets of rows of droplets oriented along fast and slow axes, with droplets of each row offset along the slow axis relative to droplets in adjacent rows.
