What are the different types of electronic displays?

CRT - Cathode Ray Tube: This is the oldest type of display, the one that almost no one has anymore. It's depth is big, not ideal.

LCD - Liquid Crystal Display: Most common type of display these days.

Plasma - http://en.wikipedia.org/wiki/Plasma_display

LED Display - Light Emitting Diode Display: More of a gimmick than anything. The key difference between LED and LCD displays is that instead of fluorescent bulbs being used as a backlight, it's just LED's around the edge of the screen. Same thing, waste of money.

OLED - Organic Light Emitting Diode: Now this is different because each pixel is individually illuminated, versus being backlit. This allows for the display to be extremely thin, 3mm for example.

Projector - Latest type is DLP, or Digital Light Projection, made almost exclusively by Mitsubishi. A laser fires light beams at a mirror and then get projected onto the screen, thus giving you an image.
