Comparison with existing forms of illumination

  OLED lighting Incandescentlight bulbs Fluorescent lamps LED
Illustration OLED lighting Incandescentlight bulbs Fluorescent lamps LED
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.
