Graphical LCD Interfacing Board

Quick Overview
LCD stands for Liquid Crystal Dispaly. 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 LCDs are thus used to display customized characters and images. The Graphical LCDs find use in many applications; they are used in video games, mobile phones, lifts etc. as display units.
