Projectors

Enable images on the computer screen to be magnified and projected onto a bigger screen

Use two types of technologies

LCD (liquid crystal display) system

Images are projected as light shines through a layer of liquid crystal cells

DLP (digital light processing) system

Uses tiny mirrors that reside on a special microchip called the Digital Micromirror Device (DMD)

Images are smoother and have better contrast than those created using LCD
