Backlit displays cover various presentations. A backlit display could be a simple frame incorporating some form of illumination that shines through the presented image or media. Backlit displays can also be large displays with an illuminated back drop, such as a shop front window or museum exhibit. White translucent panels hide fluorescent tubes that make an eye catching display enticing customers to take a closer look. Spot lights can be added that point towards the display giving an even more appealing presentation. In recent times an increase in LED availability and performance has seen many backlit displays move from fluorescent tubes to more efficient LED types. Light boxes for photography and x-rays can also be classed as a backlit display.
