Projection TV conjures up images from the past in my mind of a very large TV with a very large picture that left something to be desired in terms of sharpness and clarity. But wait, times have changed.

Digital Light Processing Rear Projection television, better known as DLP TV, uses light and mirrors to bring clear, bright, big-screen viewing to your home. Just what is DLP technology and how does it compare with the other current big screen technologies?

DLP technology originated in the 1980s. Dr. Larry Hornbeck of Texas Instruments invented the DLP chip. This chip plus sophisticated electronics equals DLP technology. It was developed, improved upon, and brought to market in 1996. Basically, this is a technology that manipulates light digitally. DLP technology is used in some of the smallest projectors and some of the largest screens. Today there are more than 75 manufacturers that use DLP technology. Here we'll look at DLP TVs. There are four main components in DLP TVs: The DMD (digital micromirror device) chip; a color wheel; light source; and optics. What are its features and advantages?

Ads for DLP TVs sing its praises with phrases like "brilliant colors," "rich blacks," "high contrast," and "clear, sharp pictures." Many reviewers and critics agree that brightness of picture is one of its strongest attributes. According to one manufacturer, DLP TV is a "movie theater experience." Other plusses include the large screen at a relatively low weight and depth. While the depth of DLPs typically ranges from 15" to 20" and the plasma norm is 3.5", there are newer lines being introduced at 7" depth. The claims are they can be hung on a wall just as plasmas can. A DLP TV carries a much lower price tag than a plasma TV. The weight of DLPs is 85 to 100 lbs. as compared to the 300 to 400 lbs. of CRT TVs. All DLPs are HD-capable and most are PC-ready.

Screen sizes range from 40" to 71" at this time. Larger screens may soon be on the market. The 50" and 61" sizes are very popular. DLP TVs are best viewed at eye level, so placement in the room is an important consideration. Optional stands are available from the manufacturer. You might consider a DLP TV motorized lift which can conceal the TV in a cabinet when not in use.

DLP technology is in its third generation. In addition to DLP technology for rear projection TV, there is LCD rear projection, CRT rear projection, and LCOS rear projection. Look for the front-runner to be the technology that will produce the best picture at a reasonable price.

The future is bright for great value in big screen TV. So, sit back, pass the popcorn, and enjoy!
