Samsung's 14-inch transparent OLED laptop from CES 2010. One of the reasons why OLED technology is cool is the fact that you can create a semi-transparent OLED screen. We’re not quite sure how useful this technology really is, except for looking through your laptop when everyone thinks you’re looking at it, but imagining a future with a bunch of semi-transparent gadgetry around us somehow fills us with glee. Samsung has decided to take a step into the future, creating a 14-inch notebook prototype with a semi-transparent screen.
