A digital advertising pillar comes from the German company KinotonPotential applications of the display should be found in the digital signage field in public areas.
Technology
The Litefast display consists of a glass cylinder and four aluminium bars with 3 LED strips in the colours red, green and blue. The aluminium bars with the LEDs on them rotate in this inner cylinder with a speed that allows them to be not seen by the human eye. The LEDs are controlled to light up at the same point all the time. This allows a display with about 16 million colours.
Construction of a Litefast displays
Advantages compared to flat displays are energy savings, as only twelve LED strips are used. 189 inch screens at small stand space are possible. With the transparency interesting visual effects are possible.
Critical issues
The viewer watches the cylinder with a frontal view. He sees a rectangle on which sides the horizontal pixels accumulate and so the image is distorted. Because of this more than a half of the screen is useless to the spectator. Consistently high luminosity with low power consumption because of the few LEDs is an argument, but I suspect that for the rotation a lot of energy is needed.

Application scenarios
The display could be used in railway stations, airports, service companies, adventure and theme parks, museums and exhibitions, retail, cinema and theatre, and in the hospitality industry. In my opinion, the main application will take part at trade fairs and exhibitions. Here the unusual shape of the display will bring a lot of attention.
