1.1                                                      INTRODUCTION

Communication has become inevitable and vital thing in this present age, it is even believed to be a commodity meant for consumption by any targeted audience. One of the important qualities possessed by all animals is the ability to communicate with each other or one another at a given time.

An information display is a way of providing information and is used as an object for notification. It can be used for both indoor and outdoor which makes it universal fit for any form of alerts.

The extent of development in information dissemination has made it possible that the well known method of displaying information using sign posts, placards, notice boards, etc has to be modified by using intelligent display board.

In the previous years, the means by which adverts, information are display has been through the use of static mode of sign display such as banners, flyers etc, they are becoming boring and unattractive.

Electronic display board display advertisements are designated to catch a people’s attention and create a memorable impression very quickly, leaving the reader thinking about the advertisement after they have driven past it. They have to be readable in a very short time because, they are usually read while being passed at high speeds.

This piece of digital technology can be found in a number of places and are being used for different purposes.

In banks, it is used to display interest rates as well as exchange rates. In hotels and pubs, it is used to display the menu and prices, in schools it is used to display information related to the school programme and update news,

1.1                                                      BACKGROUND OF THE STUDY

Electronic sign pattern display system as used in this reports refers to a sign that uses electronic hardware and software to display its copy, messages or images. Also, a sign utilizing a fixed light source to provide a message in text, images pictures, and / or symbols that may appear to move or may appear as on/off messages. This is contrast to traditional non-electronic signs where the copy displayed is physically applied to the sign surface by printing, painting or otherwise attaching it onto the sign. The materials or substrate to which the copy is applied is typically paper, wood, plastic or the wall of a building.

In this modern time, solid materials have helped man to show that he really exists by doing wonders in the world of electronics. One major development, made possible by the enormous advances in solid state technology, is the “digital revolution”. Circuits are designed to implement the basic digital logic functions fundamental to all digital systems. Digital electronics therefore comprises the design, manufacture and use of circuits for processing information in digital form (Simpson, 1978).

An information display is a way of providing information and it is also used as an object for promotion. It can be seen in a form of cardboard or tarpaulin at stores / shops, sign posts, placards, notice boards and intelligent display board. But the advent of new technologies has made the information in the form of an intelligent display board in the world of advertisements and promotions (Gupta et al, 2013). The ability to display a short message can be useful application to be available for any business. Intelligent display board system is perfect for this application. It can be used for both indoor and outdoor which makes it universal fit for any business or event. Intelligent display board system is very efficient and cost effective way to spread messages to thousands of people, without any personal contact or door to door sales. Light-Emitting Diode (LED) is a solid state light source with several attractive properties for display application. LED is a diode that gives off visible light when forward biased (Mehta and Mehta, 2014). It is chosen as the main component for displaying messages because, today LED is the most energy efficiency example and other useful systems.

The birth of signs and display can be said to be as old as the existence of man on the planet earth. From the beginning of the world, different types of displays have been in use, each mode to serve the purpose of invention efficiently. Signs are any kind of visual graphics created to display information to a particular audience (David, 2013). In 1389, King Richard II of England compelled landlords to erect signs outside their premises (Manton, 2008). In ancient Rome, signboards were usually made from stone or terracotta (Chris, 1995).

With the advancement in technology, man started carving woods and trees. The use of special dyes on wood as a means of identifying special locations. With the discovery of Bronze and iron, man started using the materials to display sign, thus the advent of metal sign boards were born, which are mostly used in developing countries. On semiconductors and vacuum tubes technology, light displays and sign boards were built to add more beauty in the old system and as a way to increase visibility. LED technology is frequently used in signs now instead of Neon signs, introduced in 1910 at the Paris Motor show (Bellu, 2006). The use of electronic is now becoming very important. It is extensively applied in almost our day to day activities.

Electronic display board system is also used for outdoor advertisement. Before, outdoor advertising was mainly characterized by the use of paper. Every bus stop and display board had a paper advertisement inside. The reason for this was simple paper was easy to use and extremely cheap. It had some draw backs as well. Before an image is actually on the street, it first has to be printed, pasted and placed. The journey from design to placement is quite long. Another disadvantages is the considerable amount waste generated by the use of paper. Finally, many people ignore a paper advertisement and there attention is drawn to the vibrant environment around them and not to a still image.

The extent of development in information dissemination has made it possible that the well known method of displaying information using sign posts, notice boards, etc has to be modified by using electronic digital display system. In today’s rapidly advancing technology market, most conventional digital display system are not being implemented using individual logic gates and integrated circuits (ICs) such have been used in the past instead, programmable devices such as microprocessor and microcontroller chips which contain the circuitry necessary to create logic functions are being used to implement digital systems.
1.2                                                      PROJECT MOTIVATION

The motivation of this project comes from the change involved with information in respect to time this days now prompt the huge step of constructing a reprogrammable electronic display board to give information about anything at a particular moment to the targeted audience and need to know how electronic display board can at least provide some improved measures to the limitations of conventional display listed in the problem statements. The astonishing and spectacular display of an electronic display is as well a source of inspiration.

1.3                                                      AIM OF THE PROJECT

To design and construct an electronic display board

1.4                                          STATEMENT OF THE PROBLEM

Due to limitation of the sign board or local sign board which could not display clearly at night expect light shines on it, it is then necessary that electronic display system is employed to counter the limits of the local sign board. The information displayed on the local sign board is less attractive compared to the information displayed using intelligent display board system.

Thus, researchers are prompted to tirelessly hold up to these challenges by initiating some means of improving the above among which is the design and construction of an intelligent display board system.

1.5                                          OBJECTIVES OF THE STUDY
