What isDLP projector

Digital Light Processing (DLP) technology uses micro mirrors to project images from a monitor onto a large screen. It was invented by Larry Hornbeck of Texas Instruments in 1987. The first DLP-based projector was introduced by Digital Projection Ltd in 1997. Both companies received Emmy Awards in 1998 for their contribution to DLP projector technology.

How Does DLP Technology Work?

Each mirror on a DLP chip is about the size of a red blood cell. These mirrors manipulate light to create an image. The mirrors must change position on a microscopic suspension hinge at incredible speeds, up to 16 million cycles per second.

Each mirror creates an image in response to data from the video source. In the “On” position, the mirror reflects light back onto the screen, creating a visible pixel. In the “Off” position, the mirrors reflect light away from the projection lens. This prevents light from traveling to the screen.

Where is DLP Used?

DLP technology is used in a variety of display applications, from traditional static displays to interactive displays. It is also used in non-traditional embedded applications, including medical, security, and industrial uses. DLP is seen on stand-alone projection units, rear-projection televisions, and most digital cinema projections.

What is the Difference Between DLP and LCD?

While DLP uses micro mirrors to project images, LCD video projectors send light from a metal halide lamp through a prism to display video, images, or computer data on a flat screen or surface.


Digital Light Processing (DLP) is an innovative technology that uses micro mirrors to project images onto a large screen. It was invented in 1987 by Larry Hornbeck of Texas Instruments and has since been used in a variety of display applications, including traditional and non-traditional embedded applications. DLP is different from LCD technology in the way it projects images, making it an excellent choice for those looking for high-quality, large-scale projections.


What is a DLP projector used for?

DLP projectors are used to project images from a monitor onto a large screen. They are commonly used in home theaters, offices, schools, and other settings that require large-scale projection.

What is the lifespan of a DLP projector?

The lifespan of a DLP projector depends on the model and usage. However, most DLP projectors last between 3,000 and 6,000 hours. Replacing the lamp can extend the lifespan of the projector.

Is DLP technology better than LCD?

DLP and LCD technologies each have their pros and cons. DLP is known for producing deeper blacks, better contrast, and smoother images. However, LCD is typically brighter and has better color accuracy.
