Samsung's new transparent LCD screen, is a breakthrough that could one day make any window into a display or touchscreen. The transparent screen is available to showrooms for display cases, but Samsung has been testing its invention on vending machines.
The clear glass on the machines' windows can advertise a particular product or display nutrition information. It has been a success, with sales in vending machines equipped with the transparent LCDs up 600% over others.
Normal TV screens require back or side lighting to display an image, but Samsung's transparent screen uses ambient light like sunlight or room lighting. That makes the product relatively cheap. New ideas for use might be bathroom mirrors, department store windows, and more.
