LCD stands for Liquid Crystal Display. It can be used to display anything. They are of many types. 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; they can only display characters of certain dimensions. The Graphical LCD are thus used to display customized characters and images. The Graphical LCD find use in many applications; they are used in video games, mobile phones, lifts etc. as display units.

OVERVIEW
GRAPHICAL LCD
LCD stands for Liquid Crystal Display. It can be used to display anything. They are of many
types. The ones we commonly use for embedded systems, robotics, etc are of two types –

can only display characters of certain dimensions. The Graphical LCD are thus used to display
customized characters and images. The Graphical LCD find use in many applications; they are
used in video games, mobile phones, lifts etc. as display units.
