LED is the acronym of Light Emitting Diode and it is a semiconductor that emits visible light when electricity passes through it. The emission of light depends on electrons flowing between anode and cathode and the color of the visual emission (Red, Green, Blue, Amber, White…) depends on the material utilized. Text and images on an LED solution are created using pixels; the pixel is the “luminous dot” present on every LED device. This luminous dot can be formed by 1 or more LEDs depending on dimensions and features of the device.  The pitch (or resolution) of the screen is the distance between the pixels and determines the performance of the screen. The smaller the pitch: the closer the pixels: the higher the resolution: the shorter the minimum viewing distance, the higher quality of the image and the higher the screen’s cost per area. LEDs are brighter and more efficient than traditional lighting methods.  They produce ‘cold’ light, which saves on energy consumption and can be powered by as little as a portable battery pack or even a solar array.  LEDs emit light of the intended colour so remove the need for colour Filters.  LED screens can be programmed directly from a standard PC using the software provided.  LEDs are small and solid and are resistant to vibration and shock, their typical lifespan is in excess of 100,000 hours and can be up to as Many as 100,000 hours compared with 2-3000 hours for traditional lighting. Exceptionally fast response times are especially suited to situations of frequent on/off activity and make changing display messages simple and quick.  Having a bright LED sign could be the difference between success and failure of a commercial activity.
