Graphic LCD 128×64 Blue RHD are different from the ordinary alphanumeric lcds, like 16×1 16×2 16×4 20×1 20×2 etc. They (ordinary) can print only characters or custom made characters. They have a fixed size for displaying a character normally 5×7 or 5×8 matrix. Where as in graphical lcd we have 128×64=8192 dots each dot can be lit up as our wish or we can make pixels with 8 dots ie. 8192/8=1024 pixels. We can design a character in a size which we need. More over we can make a picture on a graphical LCD as well.
