Abstract
Recently LED display panels are widely used throughout the world in all situations to create images for visual displays in a variety of applications including communication and visual display devices. LED array display board is a popular instrument for commercial usage. Many banks, shops and cinemas are willing to install one piece of it because of its versatility. LED array display board can be very bright and eye-catching. A display sign used for advertising or for displaying direction or other information to motorists has an important feature in common. This research provides an efficient and scalable approach to LED Dot Matrix displays. The system is comprised of a tricolor dot matrix display panel with an interface circuit to a computer. It also comprises an executive program that runs on the computer for the display control of characters, decorative pattern or messages. The display board shows any character entered from the host computer which is interfaced using USB to a microcontroller that initializes the led driver. The advantage of this research is that size of the display board can be increased row wise and column wise without making any changes in the circuitry since display board is the repetition of a small independent module.
