LCD Vs DLP Projectors

In case you’ve been thinking about shopping for a home theater top 10 mini projector, perhaps to connect to an HDTV tuner, and have read reviews or finished slightly bit of analysis, you will be aware that there are two technologies competing for the contents of your wallet.

Both LCD and DLP are used in projectors suitable for dwelling theaters, but they work in fairly alternative ways and produce slightly different results. For those who ask round ‘ significantly in electronics shops, you are likely to be supplied with a mass of knowledge that is confusing and sometimes just plain wrong. So here, in an effort to clear the fog surrounding projectors, is our guide to LCD v DLP.

LCD

LCD projectors have three separate LCD panels, one for red, one for green, and one for blue parts of the image being processed by the projector. As light passess through the LCD panels, individual pixels (or picture parts) could be both opened or closed to either enable light to pass by means of or be filtered out. In this manner the light is modulated and an image projected on to the screen.

LCD projectors have historically had three most important advantages over DLP. They produce more accurate colors (due to the three separate LCD panels), they produce a slightly sharper image (though this is pretty much as good as undetectable when watching movies) and they are more light-environment friendly, which means they produce brighter images utilizing less power.

Nonetheless, LCD projectors also have some disadvantages, though because the technology improves these have gotten less and less relevant. The first of those is pixelation, or what’s generally known as the screen door effect. This signifies that generally you can see the person pixels and it appears as though you’re viewing the image through a ‘screendoor.’ The second historic disadvantage of LCD v DLP is that LCD would not produce absolute black, which means that contrast is less than you’ll get with DLP.

Nonetheless, the advent of higher resoltion LCD projectors (particularly ‘HD-ready’ projectors which have a horizontal decision of 768 pixels or larger) means that pixelation is less of an issue than it used to be. And the improved capability of LCDs to produce high-distinction images can be allowing them to be taken more seriously by residence theater enthusiasts.

DLP

Digital Light Processing (DLP) is a technology developed by Texas Instruments and it really works by projecting light from the projector’s lamp onto a DLP chip, made up of 1000’s of tiny mirrors. Each mirror represents a single pixel and directs the light projected onto it either into the lens path to turn the pixel on or away from it to show it off. Most DLP projectors have just one chip, so to be able to reproduce colour, a shade wheel consisting of red, green, blue and typically, white filters is used. The wheel spins between the lamp and the chip and changes the color of the light hitting the chip from red, to green, blue. Each mirror on the DLP chip tilts towards or away from the lens path depending on how a lot of a particular colour light is required for that pixel at any given instant.
