ABSTRACT
LED's are a fantastic way to illuminate any kind of sign,
be it lettering or panels. LED Dot-Matrix Displays are a common sight
nowadays on streets, malls, buildings, parks and other public places. It is a
way of visual information where large LCD and other display become too much
expensive. The commonly seen displays are single coloured or having 2 or 3
colours .But here multicoloured LED display is being introduced .This project
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 on the display panel. A multicolour LED Indoor Advertising Display can be used by companies to advertise even in bright
day-light conditions. The display board displays any character
entered from the host computer which is interfaced using USB to a
microcontroller that initializes the led driver. The advantage of this project
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.
