    摘要: A first device is provided that includes a first light source (301) 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 (304) 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 (305) 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 (303) 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 (302) that emits near white light that may have a CCT that is less than 6504 K.

    摘要: A first method comprises providing a plurality of organic light emitting devices (310-312) (OLEDs) on a first substrate (300). Each of the OLEDs (310-312) includes a transmissive top electrode (322). The plurality of OLEDs includes a first portion of OLEDs (310) and a second portion of OLEDs (311) that is different from the first portion. The first method further includes depositing a first capping layer (302) over at least the first portion of the plurality of OLEDs (310) such that the first capping layer (302) is optically coupled to at the first portion of the plurality of OLEDs (310). A second capping layer (303) is deposited over at the second portion of the plurality of OLEDs (311) such that the second capping layer (303) is optically coupled to the second portion of the plurality of OLEDs (311) but not the first portion of the plurality of OLEDs (310).
