What is an LED?
An LED(Light Emitting display) is a horizontal panel display, which is an arrangement of emitting diodes as pixels for a video display. These pixels are a grouping of three LED's: Red, Green, and Blue. Pixel pitch is normally within a range of 9-mm to 100-mm.The brightness is very much enough to visible in the sun for store-sign and billboard and in recent times they were also become commonly used in destination sign on a public transport vehicle, as well as different signs on the highway. The main purpose of the LED display is to provide general illumination in addition to the general display. Find More detail @ http://www.pixeldiode.com/
