LCD Vs DLP Projectors

Should you’ve been thinking about shopping for a home theater projector, perhaps to hook up with an HDTV tuner, and have read evaluations or performed slightly bit of research, you will be aware that there are technologies competing for the contents of your wallet.

Each LCD and DLP are used in projectors suitable for dwelling theaters, but they work in quite different ways and produce slightly totally different results. In case you ask around ‘ particularly in electronics shops, you’re likely to be provided with a mass of data that is confusing and sometimes just plain wrong. So right 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 components of the image being processed by the projector. As light passess via the LCD panels, individual pixels (or picture components) can be both opened or closed to both enable light to pass through or be filtered out. In this approach the light is modulated and an image projected on to the screen.

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

However, LCD projectors even have some disadvantages, though as the know-how improves these have gotten less and less relevant. The first of those is pixelation, or what’s often called the screen door effect. This means that typically you may see the person pixels and it seems to be as if you are viewing the image by a ‘screendoor.’ The second historic disadvantage of LCD v DLP is that LCD would not produce absolute black, which implies that contrast is less than you’d get with DLP.

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


Digital Light Processing (DLP Projector) is a know-how developed by Texas Instruments and it really works by projecting light from the projector’s lamp onto a DLP chip, made up of hundreds of tiny mirrors. Every mirror represents a single pixel and directs the light projected onto it either into the lens path to show the pixel on or away from it to show it off. Most DLP projectors have only one chip, so with a purpose to reproduce color, a coloration wheel consisting of red, green, blue and sometimes, white filters is used. The wheel spins between the lamp and the chip and adjustments the colour 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 specific color light is required for that pixel at any given instant.
