Abstract: An organic light emitting display comprises a display panel having a plurality of pixels, a gate drive circuit that drives scan lines and emission lines on the display panel, and a data drive circuit that drives data lines on the display panel. Each of the pixels is arranged in an nth row. A single frame for the organic light emitting display comprises an initial period in which the gate voltage of a driving transistor is initialized, a sampling period for compensating the threshold voltage of the driving transistor, and a light emission period in which an organic light emitting diode emits light. A value corresponding to an image signal to be displayed by the organic light emitting diode is applied to a data line during the sampling period, and an initial voltage is applied to one electrode of a capacitor during the initial period.

Abstract: A display device for virtual reality. A first display panel comprises a first pixel row having a first end and a second end that is closer to the second display panel than the first end. The first pixel row has a first arrangement of unit pixels that alternate between a first unit pixel type and a second unit pixel type. A second display panel comprises a second pixel row aligned with the first pixel row and having a third end and a fourth end that is further from the first display panel than the third end. A first unit pixel at the first end of the first pixel row is the first unit pixel type, and a second unit pixel at the third end of the second pixel row is the second unit pixel type.
