DESCRIPTION

LCD stands for Liquid Crystal Display. It can be used to display anything. They are of manytypes. The ones we commonly use for embedded systems, robotics, etc are of two types –character LCD and graphical LCD. The 16x2 LCD Characters have their own limitations; theycan only display characters of certain dimensions. The Graphical LCD are thus used to displaycustomized characters and images. The Graphical LCD find use in many applications; they areused in video games, mobile phones, lifts etc. as display units.
