Ipod+Touch

=The iPod Touch= The LCD (liquid crystal display) Screen: The ipod touch screen is made out of liquid crystals solids are frozen lumps of matter that stay put all by themselves, often with their [|atoms] packed in a neat, regular arrangement called a crystal (or crystalline lattice). Liquids lack the order of solids and, though they stay put if you keep them in a container, they flow relatively easily when you pour them out. Now imagine a substance with some of the order of a solid and some of the fluidity of a liquid, what you have is a liquid crystal. This type of screen can show up to 200 multi-colors. Also they are tiny pixels that get turn into liquid crystals.
