Abstract: A display panel in one example includes pixel blocks having subpixels disposed in a display area, a bezel area disposed outside the display area, and mode control line sets individually connected to pixel blocks. Each mode control line set includes a first mode control line for supplying a first mode control signal and a second mode control line for supplying a second mode control signal. Each subpixel includes a driving transistor connected to a first power line, a first light emitting device connected to the driving transistor through a first mode control transistor controlled by the first mode control signal, a second light emitting device connected to the driving transistor through a second mode control transistor controlled by the second mode control signal, a first lens region disposed on the first light emitting device, and a second lens region disposed on the second light emitting device.

Abstract: An organic light-emitting display device and a driving method thereof. A first pixel of the plurality of pixels is initialized in response to a first gate signal of the gate signals, receives a first data signal input thereto in response to a second gate signal generated after the first gate signal, and is controlled by the emission control signal to emit light in response to the first data signal. A second pixel of the plurality of pixels is initialized in response to the second gate signal, receives a second data signal input thereto in response to a third gate signal generated after the second gate signal, and is controlled by the emission control signal to emit light in response to the second data signal. The size of a non-display area is reduced.

Abstract: The present disclosure relates to an organic light emitting display and an apparatus for driving the same. According to the present aspects, a first light emitting transistor can be maintained to be in a turn-off state from an initial interval to a holding interval, whereby a short-circuit between data voltage and reference voltage, which occurs when the first light emitting transistor is turned on in the initial interval, can be prevented.
