Big screen rear-projection televisions range in size of up to 70 inches. RPTV sets use three different colored guns and a series of mirrors to project images onto their huge display screens.

These RPTV sets typically cost more than most analogue TVs because they offer larger screens and better quality. Front projection displays are the ultimate in size and quality. Unrivaled by analogue TV screens for size, many high-end dedicated home theater rooms rely on front projection to display the video signal.

The type of television you have in your living room is likely an analogue TV. It relies on a cathode ray tube, commonly called a CRT, to display images. A set of electrons project light onto a phosphor-coated screen that glows when struck by the beam. This series of events ultimately leads to the image you see on your television screen. Most analogue TVs use interlaced scan.

Interlaced scan draws half of the lines on the television screen in one pass. Then it comes back and fills in the other half of the lines on the next pass. It repeats this refresh process between 50 and 60 times every second. On the first pass, an interlaced scan television draws all the odd lines. Then it repeats the process by drawing all the even lines.
