LCD Vs DLP Projectors

In the event you’ve been thinking about shopping for a home theater projector, perhaps to connect with an HDTV tuner, and have read opinions or done slightly little bit of research, you’ll be aware that there are two applied sciences competing for the contents of your wallet.

Both LCD and DLP are used in projectors suitable for residence theaters, however they work in quite alternative ways and produce slightly completely different results. When you ask around ‘ significantly in electronics shops, you are more 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 information to LCD v DLP.


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 image parts) may be both opened or closed to both 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 fundamental advantages over DLP. They produce more accurate colors (as a result of three separate LCD panels), they produce a slightly sharper image (though this is nearly as good as undetectable when watching motion pictures) and they’re more light-efficient, which means they produce brighter images utilizing less power.

Nevertheless, LCD projectors even have some disadvantages, though as the expertise improves these are becoming less and less relevant. The first of those is pixelation, or what’s referred to as the screen door effect. This signifies that sometimes you may see the person pixels and it appears to be like as if you’re viewing the image by way of a ‘screendoor.’ The second historic disadvantage of LCD v DLP is that LCD doesn’t produce absolute black, which implies that contrast is less than you would get with DLP.

Nevertheless, the advent of higher resoltion LCD projectors (significantly ‘HD-ready’ projectors which have a horizontal resolution of 768 pixels or greater) means that pixelation is less of an issue than it used to be. And the improved means of LCDs to supply high-contrast images is also allowing them to be taken more significantly by house theater enthusiasts.


Digital Light Processing (DLP) is a expertise developed by Texas Instruments and it really works by projecting light from the top 10 mini projector‘s lamp onto a DLP chip, made up of thousands of tiny mirrors. Every 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 turn it off. Most DLP projectors have just one chip, so with a view to reproduce color, a color wheel consisting of red, green, blue and sometimes, 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 relying on how much of a specific colour light is required for that pixel at any given instant.
