1. A device comprising:
an active-matrix driven display including a plurality of OLED pixels, each OLED pixel comprising:
not more than three sub-pixels, wherein each of the not more than three sub-pixels is a sub-pixel containing a phosphorescent material, and wherein a first sub-pixel of the not more than three sub-pixels is configured to emit blue light in a light blue range of the visible spectrum having a peak emission wavelength in the range of 465-500 nm, a second sub-pixel is configured to emit red light in a red light range of the visible spectrum having a peak emission wavelength in the range of 580-700 nm, and a third sub-pixel is configured to emit green light in a green light range of the visible spectrum having a peak emission wavelength of 500-600 nm, and
wherein each sub-pixel of the plurality of OLED pixels that is configured to emit blue light only emits blue light in the light blue range, and wherein each pixel comprises no sub-pixels that are configured to emit deep blue light.
