What Is The DLP Projector Technology?

DLP Projector Technology is a ground breaking advancement in the world of home video projection, and it’s only going to get better. The DLP projector technology uses a tiny mirror to reflect light onto a digital colour wheel that determines the exact red, green and blue levels for projected images. As this technology advances, we can expect brighter images with more vibrant colours.

One of the most exciting developments in recent years has been the introduction of 3-D capability into modern projectors. This allows users to have an immersive experience while watching videos or playing games at home. With these advancements we will be able to see realistic movement from objects on screen as well as depth perception which would allow us to feel like we’re actually there! What was once only available in the theatre will soon be a reality at home.

DLP projectors: What Is It?

People often compare DLP projectors to LCD and other display technologies, but what is it that makes DLP so special? The answer lies in the fundamentals of how a projector works. There are two basic optical systems: projection by lens and projection by mirrors. The Lumens LM60 DLP projector is an example of projection by mirrors. The image begins with a light source, either the sun or an artificial bulb called a lamp. This light then reflects off what is known as a reflective material, usually made of metal or glass.

What is DLP Technology

DLP  abbreviated as (Digital Light Processing)  they are using as a chip made of tiny microscopic mirrors and a spinning colours wheel to create an image. DLP projectors deliver sharp images, don’t need any filters, have a better response time as well as 3D capabilities.

Jim Stewartson from Projector Central says, “DLP stands for Digital Light Processing. This method of image projection offers a number of advantages over other technologies.”
“In a projector using the DLP technique, a single chip of electronics, usually just one tenth the size of a 1×1-inch chip used in computers, replaces thousands of components inside the projector’s mechanical assembly. The simplicity and reliability of this innovative technology has made it possible to manufacture projectors that are not only inexpensive but also extremely compact.”

How Does DLP Technology Work?

Inside the DLP chip is an electrically controlled mirror which can alternate rapidly between up to 2 different settings. One setting reflects light towards the lens and onto the screen, while the other side blocks it and provides a black or dark screen. The digital aspect of this technology means that this mirror can be made to keep switching back and forth between these two settings at a very high speed, up to 200 times per second!

This process happens so fast that it’s not visible to the naked eye. You’ll notice that when you watch an old school film. This forms a rapid-fire pattern of red, green, blue flashes on the screen – in other words, pixels – which are then painted by your digital source for your viewing pleasure.

Colors in DLP projector:

There are two primary method by which DLP projection system creates a color image those used by single chip DLP projectors, and those used by three_ chips projector . A third method sequential illumination by three colors light emitted diodes , is being developed and is currently used in televisions manufactured by SAMSUNG.

History of DLP Technology

The first DLP-based digital projector was invented by the Texas Instruments, who unveiled their invention at the 1991 SID Show.
There are two basic optical systems: projection by lens and projection by mirrors. The Lumens LM60 DLP projector is an example of projection by mirrors. The image begins with a light source, either the sun or an artificial bulb called a lamp. This light then reflects off what is known as a reflective material, usually made of metal or glass.

How this technology will advance in the future

This technology will advance in the future by introducing a new way to project images. This method is known as projection accompanied by color, and it is being developed at Stanford University. The developers of this device have been experimenting with a way to miniaturize an LCD projector down to a size that is considerably smaller than a sugar cube. DLP technology also has the advantage of being able to project three-dimensional image.

Frequently Asked Questions

Is DLP a laser?

DLP technology is a type of projective involving a digital micromirror device, or DMD. A single chip of electronics, usually just one tenth the size of a 1×1-inch chip used in computers, replaces thousands of components inside the projector’s mechanical assembly. The simplicity and reliability of this innovative technology has made it possible to manufacture projectors that are not only inexpensive but also extremely compact.

DLP technology projects color by alternately projecting red, green, and blue pictures in rapid succession over the surface of an intensely illuminated digital micromirror device (DMD). This happens so fast that it’s not visible to the naked eye. You’ll notice that when you watch an old school film.

What is better: DLP or LCD projectors?

As far as DLP projectors go, the lamps are brighter and last longer. This is because they do not have to turn on and off at high speeds, which would make the lamp life shorter. With LCD projectors, it is cheaper to buy but the lamp life is lower.

PROS:

  • Smooth (at 1080p resolution) jitter-free image.
  • Perfect geometry and excellent grayscale linearity achievable.
  • Usually excellent ANSI contrast.
  • The light from the projected image is not inherently polarized.
  • DLP offers affordable 3D projection display from the single unit and can be used with both active and passive 3D solutions.

CONS:

  • May use more electricity , and generate more heat then competing technologies.
  • Reduced viewing angle as compared to direct view technologies such as CRT, plasma, and LCD.
  • Error – diffusion artifacts caused by averaging a shade over different pixels, since one pixels cannot render the shade exactly.

Conclusion

DLP projectors are one of the most popular type of home projection system, but there is always room for improvement. The DLP projector technology uses a tiny mirror to reflect light onto a digital color wheel that determines the exact red, green and blue levels for projected images. As this technology advances, we can expect brighter images with more vibrant colours!
