A networked lighting system including a plurality of OLED devices can have a variable light field based on a feedback.

Abstract: A lighting system includes a plurality of organic light emitting diode (OLED) devices. By selecting the plurality of OLED devices, or by selectively controlling the plurality of OLED devices, the color characteristics of the lighting system can be tuned. The lifespan of the lighting system can be improved.

Abstract: Mosaic devices including an apparatus includes at least one electroluminescence (EL) device and a system substrate. The at least one EL device can be configured to be coupled mechanically and electrically to the system substrate. The system substrate can be configured to receive the at least one EL device at a non-discrete location or orientation. The system substrate can be a smart system substrate configured to automatically identify a device type. The EL device can be an area-emitting device such as an organic light emitting diode (OLED) device.

Abstract: An organic light emitting diode (OLED) device includes a substrate, an anode, a cathode, an active region including an organic material, wherein the active region is electrically coupled to the anode and the cathode, at least one coupler configured to electrically couple at least one of the anode or the cathode to a power supply, and an encapsulation that isolates the active region from an ambient environment. A lighting system can be made including a plurality of OLED devices. A lighting system can be assembled using the OLED devices from a kit. The OLED devices may be polymer light emitting diode (PLED) devices or small molecule light emitting diode (SMOLED) devices. The OLED devices can use regio-regular poly-thiophene.

Abstract: Compositions for use in HIL/HTL applications include intrinsically conductive polymer, planarizing agent, and dopant, which are soluble in non-aqueous solvents. Block copolymers of regioregular alkyl/alkoxy- and aryl-substituted polythiophenes can be used. The compositions can be formed into thin films. Excellent efficiency and lifetime stability can be achieved.

Abstract: Regio-regular polythiophenes used in diodes which are not light emitting or photovoltaic. High quality, processable thin film polymer films can be made. The thin film can have a thickness of about 50 nm to about one micron, and the conductive thin film can be applied by spin casting, drop casting, screening, ink-jetting, transfer or roll coating. The polythiophenes can be homopolymers or copolymers. The regio-regular poly(3-substitutedthiophene) can be derivatized so that the 3-substituent is an alkyl, aryl, or alkyl/aryl moiety with a heteroatom substitution in either the ?- or beta-position of the 3-substituent.

Abstract: Regioregular polythiophenes having heteroatoms in the substituents can be used in hole injection layer and hole transport layers for electroluminescent devices. Copolymers and organic oxidants can be used. Homopolymers can be used. Metallic impurities can be removed. The heteroatom can be oxygen and can be substituted at the 3-position. Advantages include versatility, synthetic control, and good thermal stability. Different device designs can be used.

Abstract: Regioregular polythiophene polymers can be used in photovoltaic applications including copolymers and blends. The polymer can comprise heteroatoms in the side groups. Better efficiencies can be achieved.
