see-thru computer screens that don't require power-sucking backlights to function. Unfortunately, it looks like the amazing AMOLED variety is still on the drawing board, but ambient light-powered LCDs are on the way, with Samsung offering a 22-inch, 1680 x 1050 resolution panel with a 500:1 contrast ratio to begin with. Sammy suggests we'll see it in HDMI and USB-compatible monitors and suspects it'll be used in advertising and teleconferencing first -- which suggests this display won't come cheap -- but we all know the true killer app will be a nice big frameless laptop screen. We'll take two, please. PR after the break.
