ABSTRACT
The world has really turned into a
global village unlike the old forms of electronic gadgets and electronic
devices as well as one of such developments is in the liquid crystal display
(LCD), which has re-defined the computer world which includes Hotels, Banks not
forgetting Clubs and even Schools.
However, this liquid crystal display
(LCD) has various form and their uses, for example, there is the Dot-matrix
system of LCD which is connected to one another to form columns and rows and
also we have another form of liquid crystal display (LCD) known as the
segmental (7-segment and the 16-segment display) and in this system of display,
the segmental comprises of a multiplexed LEDs and it has seven displays which
does not display all the English letters. This recent progression in the
computer and electronics world relates generally to teaching systems and ways
in which information could be displayed for easy use by man.
In the chapter two of this work, it
talks about the literature review and chapter three; components used such as the
capacitors, resistors, transistors, integrated circuit (IC), transformer are
discussed.
