George Walter Reflects on 25 Years of DLP Evolution

In the latest issue of Systems Contractor News, Digital Projection’s George Walter takes a deep dive into the 25-year journey of DLP technology—from its early days to its current cutting-edge capabilities.

From large three-chip systems to today’s advanced single-chip RGB Pure Laser projectors, DLP has seen remarkable progress. One of the most significant improvements: the elimination of the distracting “rainbow” effect, made possible by moving beyond the traditional color wheel configuration.

Here’s a snippet from George on that topic from the SCN cover story:

As technology advances, the latest evolution in DLP projection is the introduction of RGB pure laser technology in combination with single-chip DLP projectors. Traditional lamp-based projectors require color wheels or phosphor-based light sources to generate colors. While effective, these methods introduced certain limitations, such as potential color separation artifacts and mechanical noise.

With RGB pure laser projection, individual red, green, and blue lasers are used as direct light sources. As a result, RGB lasers produce more vivid, true-to-life colors, achieving nearly 100% of the Rec. 2020 color gamut—the widest color space available in consumer displays. Lasers have a much longer lifespan compared to traditional projection lamps, reducing maintenance costs and enhancing durability.

Without a spinning color wheel or high-wattage lamp, RGB laser projectors generate less heat and operate more quietly, making them ideal for home theaters and professional environments. And because RGB lasers don’t rely on color wheels, the risk of color separation artifacts is completely removed. That means no more rainbows.

Sustainability is a hot topic in the AV industry, with consumers demanding technology that’s as eco-friendly as it is innovative. We’re embracing sustainability across our business, driven by the strong environmental initiatives of our parent company, Delta.

From concept to completion, Delta prioritizes energy efficiency and sustainability in its products—it’s in their DNA, and ours. This commitment influences everything from supplier selection and manufacturing to shipping practices and the materials used in our imaging solutions.

We’re making major inroads, with many of our projectors requiring half the power to produce the same brightness levels as their predecessors. By combining energy-efficient performance with localized supply chains and consolidated shipping, the total cost of ownership can often be lower than traditional power-hungry projectors.

Across our range of LED displays and projectors, you’ll see a steadfast dedication to greener innovation. We anticipate “green” will be the defining color of the year as we continue pushing the boundaries of sustainable AV technology.

Earth Day is April 22—pay tribute to the well-being of the planet by checking out some of our most efficient projectors, like the E-Vision 16000i, M-Vision 24000, and new E-Vision 10000i RGB Laser.
