Introduction of OLED Technology

What is OLED Illumination?

Comparison with existing forms of illumination

	OLED lighting	Incandescentlight bulbs	Fluorescent lamps	LED
Illustration
Principle of light emission	Emits light by applying a voltage to organic matter	Emits light by sending an electric current to a metallic filament	Ultraviolet rays generated by an electric current collide with fluorescent material to produce visible light	Emits light by applying a voltage to an inorganic semiconductor
Characteristics	Illuminates large area (surface light source) Energy efficient Low heat-generation Slim, lightweight Flexible (when plastic substrate used) Environmentally sound	Illuminates small area (point light source) High power consumption High heat-generation Closely approximates natural light	Size of area illuminated is between point light source and surface light source (linear light source) Energy efficient Uses hazardous substance (mercury)	Illuminates small area (point light source) Energy efficient Long life Easy to reduce size Environmentally sound
Uses	Anticipated applications include living spaces, offices, decorative illumination, car interior lighting, and POP lighting	Photographic lighting, living spaces such as dining rooms or bedrooms, etc.	Living spaces, offices, commercial premises, etc.	Indirect lighting, floor level lighting, spotlights for retail spaces, etc.
