Abstract: An organic light emitting display (OLED) device includes a substrate including a light emitting region and a peripheral region. An auxiliary power supply wire is disposed in the peripheral region. A lower electrode is disposed in the light emitting region. A pixel defining layer, disposed on the substrate, exposes a portion of the lower electrode and a portion of the auxiliary power supply wire. A first common layer, disposed on the pixel defining layer and the lower electrode, exposes the auxiliary power supply wire. A light emitting structure is disposed on the first common layer. The light emitting structure exposes the auxiliary power supply wire. A second common layer is disposed on the light emitting structure, the second common layer covering the light emitting structure and exposing the auxiliary power supply wire. An upper electrode is disposed on the second common layer and contacts the auxiliary power supply wire.

Abstract: A controller for a display panel may include a first supply circuit to output first and second driving voltages to a sub-pixel of a first color; and a second supply circuit to output third and fourth driving voltages to a sub-pixel of a second color. The first driving voltage may be greater than the second driving voltage, and the third driving voltage may be greater than the fourth driving voltage. Also, at least three of the first, second, third, and fourth driving voltages may be different from one another.
