 An LED (Light Emitting Diode) is a semiconductor diode with electroluminescence that converts electric energy into light. LEDs are popular illumination components in various electronic devices — including backlighting for cell phone displays and LCDs — due to their low energy consumption, long life and small size. Improvements in brightness and light-emitting efficiency have expanded LED applications to include large outdoor displays, traffic lights and digital camera flash units. The non-mercury, eco-friendly aspect of LEDs is also driving efforts to replace conventional incandescent light bulbs and fluorescent lights.
Kyocera sapphire wafers are used as the base substrate for the epitaxial growth of LED elements. With our vertically integrated production line, extending from crystal growth to finished products, Kyocera is able to produce a stable supply of high volume sapphire wafers.
