Patent ID: 8502445

Claim:
A first device comprising: a first light source that comprises at least one organic light emitting device, wherein the first light source emits near white light having a correlated color temperature (CCT) that is less than 6504 K; and: a plurality of pixels, wherein each pixel comprises: a first sub-pixel comprising a first color filter in optical communication with the first light source, wherein the first color filter is adapted to pass light from the first light source, wherein the light passed by the first color filter has a peak wavelength in the visible spectrum between 400 and 500 nm; a second sub-pixel comprising a second color filter in optical communication with the first light source, wherein the second color filter is adapted to pass light from the first light source, wherein the light passed by the second color filter has a peak wavelength in the visible spectrum between 500 and 580 nm; a third sub-pixel comprising a third color filter in optical communication with the first light source, wherein the third color filter is adapted to pass light from the first light source, wherein the light passed by the third color filter has a peak wavelength in the visible spectrum between 580 and 700 nm; and a fourth sub-pixel that emits near white light with correlated color temperature (CCT) that is less than 6504 K, wherein each of the pixels includes only the first, second, third and fourth sub-pixels.
