text: Blue LEDs, in combination with red and green LEDs (which had been discovered previously), make it possible to produce white light.
text: The LEDs in today's LED televisions are actually used only to provide a white back light, which then shines through a rapidly-refreshing LCD shutter array which tints the emanating light.
text: To produce white light, different color LEDs are combined or covered with a phosphor material that converts the color of the light to a familiar “white” light used in homes.
text: However, use of certain technologies makes an LED to emit white light.
text: LEDs that emit white light are made using two principal methods: either mixing light from multiple LEDs of various colors, or using a phosphor to convert some of the light to other colors.
text: For the purposes of practical lighting usage, the light produced must be roughly white.
text: Recent advances in LED technology have made it possible for LEDs to produce white light as well.
text: LEDs may emit light in one wavelength range, by way of example red, amber, yellow, green, blue, etc. or may be manufactured to emit white light by employing a wide variety of different types of semiconductor materials such as, for example, III-V semiconductor materials, and II-V semiconductor materials.
text: LEDs can produce white light by emitting blue light from the pn junction which is then mixed with red-to-green light created by photoluminescence in the ZnSe.
text: The relatively recent addition of silicon carbide and gallium nitride to this semiconductor palette has yielded blue-emitting diodes, which can be combined with other colors or secondary phosphors to produce LEDs that emit white light.
