    Cool link! Thanks for sharing, I had no idea Chrysler used electroluminescence in their 60's models cars... very cool.

    Thanks for the link. A quote from the article:

    "Powder phosphor-based electroluminescent panels are frequently used as backlights to liquid crystal displays. They readily provide a gentle, even illumination to the entire display while consuming relatively little electric power. This makes them convenient for battery-operated devices such as pagers, wristwatches, and computer-controlled thermostats and their gentle green-cyan glow is a common sight in the technological world. They do, however, require relatively high voltage (between 60 and 600 volts) [1]. For battery-operated devices, this voltage must be generated by a converter circuit within the device; this converter often makes an audible whine or siren sound while the backlight is activated."

    EL requires high voltage of 60 - 600 volts... interesting stuff.
