摘要:
Light emitting devices including sub-pixels having different numbers of emissive layers are provided. At least one sub-pixel of a first color may include a single emissive layer, and at least one sub-pixel of a second color may include multiple emissive layers disposed in a vertical stack. Light emitting devices in which different voltages are applied to each sub-pixel or group of sub-pixels are also provided. In some configurations, the voltage to be applied to a sub-pixel may be selected based upon the number of emissive layers in the sub-pixel.
