yeah, the only types of displays used in the car stereos that i have seen
are lcd with backlight bulb (most common),lcd with indiglo type display
(rare cause its not very bright, ive only seen a few like it), and the
sealed glass with flourescent priniting in it display (on many factory car
stereos but not that many aftermarket ones) and of course there is that
led display block but thats almost a thing of the past now (we have
washing machines that now have plasma screen displays with animations, god
talk about overkill!)
