In this paper an overview of different Light Emitting Diode (LED) display boards is presented. The enhanced LED plugs in all the loop holes in the existing product. Global Service for Message (GSM) based LED Display Board is a model for displaying notices or messages at places that require real-time noticing, by sending messages in the form of Short Message Service (SMS) through mobile. This paper proposes an idea to develop a sign board in which the messages are continuously running, where it empowers the user to change the messages using SMS instantaneously and also desk bound device such as PC or laptop. It has a dual system in terms of changing message display. It uses dual power supply such as solar power and Alternative Current (AC) power which creates the ability to work at any situation. The new design includes a motion detector which switches off the system automatically after working hours and will switch on automatically if any motion is sensed by the motion detector after the programmed working hours. This paper is a comprehensive overview of the literature and it does not contain implementation results.
