Abstract:
Large-Area lighting systems and methods of making the same. More specifically, groups of organic light emitting modules, such as organic light emitting diode modules, coupled in series with respect to on another are provided. The modules cathode of each organic light emitting module is electrically coupled to the anode of an adjacent light emitting module in an interconnect region. A portion of the cathode of each module extends adjacent to an active area of an adjacent module at an interconnect region. Methods of fabricating series groups of organic light emitting modules employing continuous material layers is also provided.
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.
Abstract:
