What are DLP projectors?

Having research a bit about NMT's within the film industry, and having discovered that DLP projectors are been brought in and widely used throughout the industry i have decided to research them in more detail.

Digital Light Processing was invented in 1987 by Texas Instruments.
DLP projectors create imagery by using microscopically small mirrors laid out in a matrix on a semiconductor chip. Each on these mirrors represents a pixel in the image that is being created, this means that the more mirrors the higher the resolution and quality of the image will be. This therefore massively enhances picture quality so is being used throughout the film industry mainly in cinema's to give viewers a more defined experience.

Due to this greatly enhanced detail, it opens the doorway to the production of 3D films which can be now watched and shown succesfully.

Advantages

• Less 'chicken wire' effect because pixels are much closer together. This doesn't make so much difference with data, but it produces smoother images for video.
  
  
  
Here is an example of the difference.

• Higher contrast achievable.

• DLP projectors are generally more poratable as fewer components are required.


• DLP projectors last longer than LCD ones.

Disadvantages

• Less colour saturation
• Generally, DLP is a better technology for home theatre than LCD . And also within the cinema.
