LCD v DLP projectors

Written by Kenny Hemphill

Continued from page 1


Digital Light Processing (DLP) is a technology developed by Texas Instruments and it works by projecting light fromrepparttar projector’s lamp onto a DLP chip, made up of thousands of tiny mirrors. Each mirror represents a single pixel and directsrepparttar 110052 light projected onto it either intorepparttar 110053 lens path to turnrepparttar 110054 pixel on or away from it to turn it off. Most DLP projectors have only one chip, so in order to reproduce color, a color wheel consisting of red, green, blue and sometimes, white filters is used. The wheel spins betweenrepparttar 110055 lamp andrepparttar 110056 chip and changesrepparttar 110057 color ofrepparttar 110058 light hittingrepparttar 110059 chip from red, to green, blue. Each mirror onrepparttar 110060 DLP chip tilts towards or away fromrepparttar 110061 lens path depending on how much of a particular colour light is required for that pixel at any given instant.

The key advantages DLP has inrepparttar 110062 LCD v DLP debate is that DLP projectors tend to be smaller and lighter, have better contrast, and don’t sufferrepparttar 110063 same pixelation problems as LCD projectors. There is one problem that some users report with DLP projectors, although it appears to only affect a very small number of people. Because ofrepparttar 110064 way DLP works, at any given instant,repparttar 110065 image on screen is either red, green, or blue. However,repparttar 110066 images change so quickly, thatrepparttar 110067 human eye doesn’t detect this and your brain putsrepparttar 110068 red, green and blue images together to make a complete frame of video. Unfortunately, some people can seerepparttar 110069 individual colours, and others can detect them enough to cause eye-strain and headaches. However, technology has improved significantly withrepparttar 110070 introduction of six-color wheels and faster rotation speeds. The rainbow effect should be a problem for even fewer people. The best way to find out if you’re affected is to try out a DLP projector, perhaps by hiring one, before you buy.

Technology in both LCD and DLP projectors is improving allrepparttar 110071 time. However, atrepparttar 110072 time of writing DLP still has a slight edge inrepparttar 110073 home theater market.
