EL Backlight
Electroluminescence
Backlight, or EL Backlight, is a solid state phenomenon which uses colored
phosphors, not heat, to generate light. EL backlights are very thin,
lightweight and provide an even light. They are available in a variety of
colors, with white being the most popular for use with LCDs. While their
power consumption is fairly low, they require voltages of 100 VAC @ 400Hz.
This is supplied by an inverter that converts a 5, 12 or 24 VDC input to the
AC output. EL backlights also have a limited life of 3,000 to 5,000 hours to half
brightness. The biggest drawbacks to an EL panel is that it requires an
inverter to generate the 100VAC, consistent brightness, and limited life. .
