LED Screen & LED Video Wall

LED Screen & LED Video Wall 
APOLLOMI Reporter

LED screen are consists of an array of hundreds of tiny red, green, and blue Light Emitting Diodes (LED) that form pixels to make up bright, clear images that are suitable for both indoor and outdoor applications.
Using a modular form, the screens can be built to nearly any size from 3m x 2m up to 10m x 10m, and can display anything that can be seen on a computer. From stills photography and graphics, to animations and live video feeds. This in its own right gets attention and creates awareness. Event ticker tapes can even be incorporated to display constant updates to spectators and the public.

As LEDs emit light rather than reflect it, they are far superior to other technologies such as projection for outdoor viewing in bright sunlight. LED screens have a wide viewing angle, essential for large audiences or where maximum coverage is required. Being an electronic diode, LEDs can handle the rapid switching that is required for moving images, and do not loose their colour should there be a drop in current.
