Digital Light Processing (DLP) was invented in 1987 by Texas Instruments. It is named for its ability to process light digitally with the aid of an optical semiconductor called a Digital Micromirror Device or DMD chip. The DMD chip is made up of over one million mirrors. The size of each mirror is less than 1/5” the width of a human hair.  They are not susceptible to burn-in, but some people do notice a glitch called Rainbow Effect (red/blue/green shadows).  They are basically modern day tube tvs (CRTs).

Like digital video camcorders, DLP devices come in either one or three-chip models. One-chip DLP systems use a projection lamp to pass white light through a color wheel that sends red-green-blue colors to the DMD chip in a sequential order to create an image on-screen. Three-chip DLP systems use a projection lamp to send white light through a prism, which creates separate red, green, and blue light beams. Each beam is sent to their respective red, green, and blue DMD chip to process the image for display on-screen.

One-chip models are said to produce a display of over 16-million colors. Three-chip models can produce a display of over 35-trillion colors.  Most consumers will be looking at the One-chips, because the three-chips are generally for very large screens, such as movie theaters.  The three-chip TVs do not suffer from the “Rainbow Effect.”  The one-chip models are still very good televisions, and have a clear and detailed display.

DLP TVs are lighter and skinnier than tubes, but are too heavy and bulky to hang from a wall.  They range in size from around 44?-75? and weigh between 65 and 215 lbs (most weigh 75-150).  They are 7-22? deep, but most models range from 15-20?.

DLP televisions vary in price, but generally will run you for around $1,500+.  This price is still a lot cheaper than comparable LCD and Plasma screens, but you either buy a big tv for a good amount of money, or get nothing.  So if you are looking for a smaller TV and do not want to spend over $1,500, look elsewhere.  The cost to replace the bulbs must also be taken into account (usually $200 per bulb).

The DLP recieves a Best TV rating of 7.

The Good: Significantly cheaper than LCD or plasma, very good picture quality for the price, pretty cheap for the size of the TV, excellent grayscale, no burn-in, smooth-stable image at 1080p,

The Bad: Bulbs need to be changed every couple of years (depending on use), bulky, slow refresh rate, not very strong with gaming/watching sports/action movies, the “Rainbow Effect,” you wont find smaller models (or prices under $1,500), weak angles, the technology is becoming dated

**If you buy a DLP TV, Best TV suggests purchasing a warranty, because the bulbs will eventually have problems
