Imagine projecting a huge image using millions of tiny, little mirrors. That’s exactly how DLP® projectors work. The advantage of using so many mirrors is simple. More mirrors. More pixels. The more pixels, the sharper the image.
By packing millions of mirrors into a tiny space, DLP projectors deliver stunning images. DLP technology is widely used in education, business, and home entertainment. It’s even the number one technology in cinema – used in 85% of all movie theaters.
What is a DLP Projector?
DLP stands for Digital Light Processing. DLP projectors beam light through a color wheel, reflection mirrors, then finally a lens.
Developed by Texas Instruments®, the DLP chip, aka digital micromirror device (DMD), differentiates DLP from LCD projectors.
Each mirror on a DLP chip is about the size of a red blood cell. These mirrors (magnified above) 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 video source data. In the “On” position, the mirror reflects light toward the screen, creating a visible pixel.
In the “Off” position, mirrors reflect light away from the projection lens. This prevents light from traveling onto the screen.
