A light-emitting device and method of producing a white appearance for a light-emitting device in an off-state are disclosed. The device includes a supporting member, an organic light emitting diode (OLED) disposed on the supporting member and a color conversion layer disposed on the OLED. The color conversion layer comprises phosphor and has a non-white appearance under ambient light when the device is in an off-state. The device further includes one or more whitening layers that have a plurality of whitening particles configured to reduce the absorption of ambient light by the color conversion layer and produce a white appearance for the device in the off-state under ambient light.
A light-emitting device comprising:
A whitening component for a light-emitting device comprising a supporting member, an organic light emitting diode (OLED) disposed on the supporting member, and a color conversion layer disposed on the OLED, wherein the whitening component comprises one or more whitening layers disposed on the color conversion layer, each whitening layer comprising a plurality of whitening particles dispersed in a binder material and configured to whiten the appearance of the device in the off-state under ambient light.
The method of producing a white appearance for a light-emitting device in an off-state, wherein the device comprises a supporting member, an organic light emitting diode (OLED) disposed on the supporting member, and a color conversion layer including an inorganic phosphor material disposed on the OLED, the method comprising:
