Light Emitting Diodes (LEDs), are semiconductors that emit light when zapped with [positive polarity] electricity.” This technology is on the verge of taking over the commercial and consumer sectors of the lighting industry. With greater efficiency, longer useful lives, and their “clean” nature, LEDs are the future of light, pushing traditional incandescent and fluorescent bulbs toward extinction.
This technology is gradually crawling into the advertisement industry also. Advertisement is the back bone of every business. Now the question arises that if you need to advertise, then what is the best medium? Time and time again it has been shown that prime time TV yields the best results, but that is very expensive. This is the reason why people have turned their attention toward Led Display.
