9. Digital projector

A digital projector is a device which connects to a computer and is used to project the video output from the computer onto a wall or screen.

In classrooms they are often used with electronic whiteboards.

The projector can be portable and placed on a stand or it can be permanently fixed to the ceiling.

Uses of digital projectors:

• Classroom teaching
• Staff training sessions
• A presentation to an audience
• Home cinemas

Although most digital projectors are fairly large in size, new technology is currently being developed to incorporate digital projection into small hand-held devices.
