It is the main determinant for how realistic an image looks. Better even than plasma. Sony's SXRD comes in second. LCDs have come a long way in recent years, and some now offer some excellent performance in their own right.
DLP, however, has not. Most projectors have an Auto Iris, which closes to dim the image on dark scenes, and remains open to keep bright scenes bright. While these do improve the apparent contrast ratio somewhat, the higher native contrast ratio of the LCoS projectors still looks better overall. For more on this, check out "Contrast ratio or how every TV manufacturer lies to you. I tie this in with contrast ratio.
Both JVC and Sony models have a high native contrast ratio, offering deep blacks at the same time as bright whites. Projectors with an iris can do one or the other and not at the same time.
This is a tough one, as light output varies a lot between projectors. LCoS projectors tend not to be as bright as certain LCD and DLP projectors, but recent LCoS projectors offer more light output than any projector from just a few years ago, so I consider all "adequate" in this regard, with some being more adequate than others.
Color accuracy varies a lot per projector. I've reviewed projectors with accurate color from all technologies. Best to check reviews to see if the model you're considering performs well in this regard. Some people aren't bothered by it, but others notice it. This is not enough to offset DLP's worse contrast ratio performance, though. DLP is seen in standalone projection units, in rear projection TVs, and in a majority of digital cinema projection.
LCD Liquid Crystal Display video projectors send light from a metal-halide lamp through a prism to display video , images, or computer data on a screen or flat surface. The ideal choice for your projector depends upon several factors: whether you want it for a home theater or office presentations; whether it has a dedicated spot or will be used when traveling often; and, of course, budget.
Other factors like sharpness, clarity, picture quality, etc. This video guides you on what factors to consider before you buy a projector:. DLP projectors rely primarily on a DLP chip, or digital micromirror device DMD , which comprises up to two million tiny mirrors, each mirror one-fifth the width of a human hair. Each of these mirrors can independently move toward or away from a light source to create a dark or light pixel. The color is fed to the DMD by a beam of light from a light lamp source, which then passes through a spinning color wheel before it reaches the chip, and the image is fed through the lens and onto the projection screen.
A DLP projector with three-chip architecture can deliver up to 35 trillion colors. A three-chip DLP projector uses a prism to split light from the lamp, and each primary color of light is routed to its own DLP chip, then recombined and routed out through the lens. Three-chip systems are in higher-end home theater and large venue projectors, and DLP Cinema projection systems in digital movie theaters.
This system combines three liquid crystal displays, where an image is created in a multi-step process. A light source provides a beam of white light, which is passed to three mirrors or dichroic mirrors specially shaped to reflect only a certain wavelength of light. Market Research. ET NOW.
