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.

Abstract: An organic light emitting display that defines a plurality of pixels arranged in a matrix form as a plurality of pixel row groups, each of which includes the same number of pixel rows and individually drives the respective pixel row groups. The organic light emitting display includes a display unit including the plurality of pixels, a plurality of data lines, and a plurality of scan lines: a scan driving unit configured to apply scan signals to the plurality of pixels; a data driving unit configured to apply data voltages that are provided to the plurality of pixels to a first output line; and a data distribution unit configured to selectively connect at least two data lines that are continuously arranged to the first output line according to demultiplexing signals. The demultiplexing signals that correspond to the pixel rows included in the respective pixel row groups have different pulse widths.
