Abstract

A first device is provided that includes a first light source that has at least one organic light emitting device that may emit near white light having a correlated color temperature (CCT) that is less than 6504K. The first device may also have a plurality of pixels comprising a first sub-pixel having a color filter in optical communication with the first light source that passes light having a peak wavelength between 400 and 500 nm. A second sub-pixel having a color filter in optical communication with the first light source that passes light having a peak wavelength between 500 and 580 nm. A third sub-pixel having a color filter in optical communication with the first light source that passes light having a peak wavelength between 580 and 700 nm. A fourth sub-pixel that emits near white light that may have a CCT that is less than 6504 K.
