Abstract

An illumination source including a first OLED layer (110) capable of emitting light of a first color; a second OLED layer (112) capable of emitting light of a second color and disposed on the first OLED layer, each of said first, second OLED layers including alternating active light-emitting areas (117) and inactive non-light emitting areas (119); said first OLED layer comprising a first substrate (118), a first transparent electrode layer (116) disposed on the substrate, a first electroluminescent layer (133) capable of emitting light of the first color disposed on the first transparent electrode layer, and a first patterned metallized electrode layer (135) forming the alternating active light-emitting areas and inactive non- light emitting areas; and said second OLED layer (112) comprising a second substrate (122), a 'second transparent electrode layer disposed on the substrate, a second electroluminescent layer capable of emitting light of the second color disposed on the second transparent electrode layer, and a second patterned metallized electrode layer forming the alternating active light-emitting areas (136) and inactive non-light emitting areas (138),- wherein light emitted by the active light-emitting areas of the first OLED layer is transmitted through the inactive non- light emitting areas of the second OLED layer. A method for tuning color and/or intensity of the light output of an illumination source is also disclosed.
