Abstract: A display device includes a substrate which includes an active area and a non-active area. The active area includes a first active area and a second active area. The display device further includes a first high potential voltage line that supplies a first high potential voltage to a plurality of first pixels in the first active area and a second high potential voltage line that supplies a second high potential voltage to a plurality of second pixels of the second active area. The first high potential voltage line and the second high potential voltage line are electrically isolated from each other. Therefore, sections of the active area are divided to separately dispose a high potential voltage line in a partial active area to uniformize the luminance in the entire panel area.

Abstract: In an embodiment, an organic light emitting display device includes a first substrate, a display region, a pad portion, lines, and a moisture-transmission delay layer. The display region includes sub-pixels disposed on the first substrate. The pad portion is disposed on the first substrate and electrically connected to an external device. The lines are disposed between the pad portion and the display region and electrically connected to the external device, and transfer a signal or power to the external device. The moisture-transmission delay layer covers edges of the lines.

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.
