Best TV Review: DLP

Digital Light Processing (DLP) was invented in 1987 by Texas Instruments. It is named for its ability to process digital light with the help of an optical semiconductor called "Digital Micromirror Device, or DMD chip. The DMD chip is composed of over a 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 are aware of a bug called the rainbow effect (red / blue shadows / green). Tube TVs are basically modern day (CRT).

As digital video cameras, DLP devices come in one or three-chip models. Single-chip DLP systems use a projection lamp to pass white light through a color wheel that sends red, green and blue colors to the DMD chip in order sequence 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 beams light blue. Each beam is sent to their respective DMD chip red, green and blue to render the image for screen display.

chip models are said to produce a display of over 16 million colors. Three first-order models can produce a display of over 35 trillion colors. Most consumers will be looking at the One-chips, because chips are generally for three large screens, such as movie theaters. Three-chip TVs do not suffer the "effect rainbow. "chip models are still very good TVs, and have a clear and detailed display.

DLP are lighter and thinner than the tubes, but are too heavy and bulky to hang on a wall. They range in size from about 44? -75? and weigh between 65 and 215 pounds (weighing 75-150). They are 7-22? deep but most models in the range 15-20?.

DLP televisions range in price but generally runs for about $ 1500 +. This price is even cheaper than comparable LCD and plasma screens, but either buy a big TV for a good amount of money or get nothing. So if you are looking for a TV smaller and do not want to spend more than $ 1,500, look elsewhere. The cost of replacing light bulbs must also be taken into account (usually $ 200 per bulb).

The DLP is given a rating of 7 Better TV.

The good: much cheaper than LCD or plasma, a very good image quality for the price, well cheap for the size of the TV, excellent grayscale, no burn, smooth stable image in 1080p,

The Bad: The bulbs should be replaced every two years (Depending on use), bulky, slow refresh rate, not very strong with the game / watching sports / action movies, the "rainbow effect" you do not find the smaller models (or prices under $ 1,500), weak corners, technology is becoming dated

** If you buy a DLP TV, Best TV suggests the purchase of a security, because the bulbs will eventually have problems
