DLP Projection

Everything You Ever Wanted to Know About DLP Projectors

The DLP chip used in DLP projectors was invented in 1987 by Dr. Larry Hornbeck, a physicist at Texas Instruments.

Is Dr. Larry’s invention right for you? Read on to find out.

How Do DLP Projectors Work?

Inside a DLP (Digital Light Processing) projector is a DLP chip covered in millions of tiny mirrors—less than a fifth the width of a human hair.

Each mirror represents a single pixel, tilting back and forth to reflect light and create a highly detailed grayscale image.

The light is then directed through a spinning color wheel, which synchronizes with the DLP chip to create the final projected image.

Pros and Cons of DLP Projectors

Pros

• DLP projectors provide much darker black levels than LCD projectors, making them popular among home theater enthusiasts.
• They offer a less pixelated image compared to very low-cost LCD projectors and deliver sharper images during fast motion scenes.

Cons

• Dollar for dollar, DLP projectors are generally not as bright as LCD counterparts.
• Some DLP projectors produce “rainbows”—a colorful trail that follows a moving object. While many users don’t notice them, others are highly sensitive. Consult a projector expert for specific models.
