Light Sources

There are various kinds of light sources such as incandescent lamps, fluorescent lamps, etc, but these conventional light sources have poor reliability, durability and luminous efficiency. Light Emitting Diodes (LED's) are excellent solid-state light sources known for their reliability and durability and thus find a lot of applications in semiconductor and photonic technologies. Recently, new kind of materials called as Light Emitting Polymers (LEP's) or Organic Light Emitting Diodes (OLED's) are being discovered that are cheaper and easy to manufacture for use in flat panel displays and related applications.
