DLP (Digital Light Processing) is a one more leading technologies which are used for the digital cinema projection. The DLP projector works on the basis of Digital Micro-mirror device (known as DMD). In this technology, the image can be created by small mirrors arranged in a matrix form on a semiconductor chip. These mirrors are microscopically small and each mirror contributes one or more pixel in image projection. The approximately number of mirrors is 450,000.

The DLP projector has color projection than any other projection. The color wheel of a DMD panel converts white color into the red, blue and green colors and DMD chip creates 16.7 million color shades of that color. In advance 3DMD chip used to create an enormous number of colors (nearly 30 trillion) to make image more attractive and visible. DLP projector is special in the rainbow effect which gives distraction in view when see from one end to another end.

DLP projector follows two methods for projection: one is single-chip DLP projector and another is three-chip projector.

Single-Chip Projector: This projector use a color wheel placed between DLP chip and lamp or produce primary colors by LED or LASER. This wheel creates primary colors like red, green and blue, in some case secondary colors like magenta, yellow and other. This color displayed sequentially at the high rate and the composition of this colors create full image for the viewers.

Three-Chip Projector: This projector able to create 30 trillion colors. So normally this projector used in cinema projection or large venue projection. I.e. these DLP projectors possibly use to improve quality of image.

There are some advantages of DLP projectors over other projectors. It gives smooth and good ANSI contrast images. Projection costs less than LCD projectors. DLP gives strong color performance as compare to other projectors. It is light weighted than LCD and plasma TVs. LED or LASER DLP projectors have longer life of lamp so need not frequently replacement. Also these projectors can be attached with DVD, VLR players and video games. This provides various models with different features so this type of projector also called as multimedia projectors.

Drawbacks of the DLP projector are it makes noise some times. To display darker image fan may create noise and older projectors may create some noise. DLP projectors are less compatible in creating view angles as compare to CRT and LCD.

But even though with drawbacks, DLP is good in accuracy in image displaying. To display dark images DLP gives more clarity and contrast. So This can be a good option for the projector.
