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.
