All you need to know about a DLP projector.

Welcome to projectors-101, an exclusively curated class that specializes in all things projectors. Just kidding.

However, this article is indeed focused on projectors; more specifically, it is focused on what a DLP projector is.

Thanks to rocket-paced technology, there is no shortage of new and wondrous things to learn about. And there exist several different types of projectors that are best suited for different needs.


What is DLP?

A digital micromirror device is used in the Digital Light Processing (DLP) chipsets based on optical micro-electro-mechanical technology. It was originally invented in 1987 by Larry Hornbeck of Texas Instruments. The DLP imaging device was created by Texas Instruments, while the first DLP projector was exhibited in 1997 by Digital Projection Ltd. In 1998, the DLP projector technology won Emmy Awards for Digital Projection and Texas Instruments. DLP is employed in a wide range of display applications, including conventional static displays, interactive displays, and non-traditional embedded uses in the fields of medicine, security, and industry.

Put simply; Digital Light Processing is referred to as DLP. DLP projectors use a color wheel, reflection mirrors, and a lens to project light.

DLP Projector Workings

The best explanation I read for DLP calls it a collection of several little mirrors. They employ millions of tiny, tiny mirrors to project a massive image. DLP projectors operate in the exact same way. The use of so many mirrors has one clear benefit. Added mirrors extra pixels. The sharper the image, the more pixels are used.

DLP projectors provide amazing visuals by fitting millions of mirrors into a small area. The usage of DLP technology is widespread in business, education, and home entertainment. It is even the most popular cinematic technology, being utilized in 85% of all cinemas.

A DLP chip’s mirrors are each roughly the size of a red blood cell. These magnified mirrors (above) use light manipulation to produce an image. At extraordinary speeds, the mirrors must move in different directions on a small suspension hinge. 16 million cycles per second or more.

Each mirror uses the data from the video source to produce an image. When the switch is turned “On,” the mirror reflects light onto the screen, producing an apparent pixel. Mirrors deflect the light away from the projection lens while they are in the “Off” position. As a result, light cannot enter the screen.

The majority of DLP projectors make use of one. The color wheel spins high-speed RGB patterns in front of the light source. Using this color technology, DLP projectors produce images with a cinematic quality.

Standard Specs to Look for in a DLP Projector

DLP projectors are available in a bewildering range of features and pricing ranges. Various pairings are appropriate for various applications. Houses of worship, lecture rooms, and portable presentations are just a few examples of their uses, from meeting spaces to interactive classrooms. You may choose the projector that is best for you if you know how you plan to use it.


Think back to the magnificent mirror-laden DLP chip. Each mirror produces one pixel. The total number of mirrors and screen resolution are the same. As an illustration, a 2K DLP projector has around 2.2 million mirrors. Approximately 8.8 million 4K devices. The quality of the images improves with resolution.

Some 4K projectors may claim to “support” 4K when compared. This is distinct from being able to replicate real 4K photos. A DLP projector needs to output at least 8 million active pixels to be considered a real UHD projector, as the Consumer Technology Association (CTA) specified. A helpful rule of thumb for selecting a comfortable viewing space is the number of persons in the room. In general, the appropriate screen size increases with the number of people in the space.


  • Less than 3,000 lumens – These projectors are used in low-lighting settings where ambient light must be completely eliminated. Use it for home theatre.
  • Between 3,000 and 4,000 lumens, a DLP projector hits its sweet spot in terms of functionality and price. These are the common brightness settings used in lecture halls, boardrooms, and living spaces where ambient light cannot be blocked off.
  • Projectors with a brightness of 4,000 lumens or more are suitable for the largest lecture halls, classrooms, or multipurpose spaces. Even on larger screens, DLP projectors in this price range deliver a sharp, clear image. This makes it possible for viewing to be simple for wider audiences. High-brightness projectors are those with lumen ratings of 4,000 or more and are utilized in upscale commercial setups.

Ambient Lighting Display

Laser projectors appear their best when used with a screen illuminated by natural light. By doing this, ambient light effects are minimized, and the stunning visuals produced by DLP laser technology are fully used. Diffuser screens and laser projectors work together to improve contrast and get rid of washed-out images in ambient light.

Reduced Input Latency

Plenty of big screens are accessible if you plan to utilize a projector outside. Following the installation of a DLP projector on their automobile, see what the Linus Tech Tips crew chose to do. Decreased input lag DLP projector input latency, measured in milliseconds, is the interval between the arrival of a video signal at a projector and its presentation on the screen. It is also known as lag. Any digital video processing will inevitably have lag. Too much lag can seriously interfere with gameplay. Thankfully, it can be reduced. Reduced input latency is a feature of gaming projectors.

And there you go. We have compiled all of the fundamental information needed to understand DLP projectors.  To know more, check out here.
