Samsung has recently showed-off their latest 46-inch transparent LCD screen. What makes this screen extra special is that it’s also powered by ambient light. You don’t need to plug the screen to make it work. You just turn on the lights in the room or let sun light in through your windows, and the screen’s solar cells will pull the power it needs from the light sources around it. On top of that, it’s a touchscreen that can recognize 10 fingers at once!
