The core of DLP technology lies in its Digital Micromirror Device (DMD) chip, which contains hundreds of thousands to millions of microscopic mirrors. DMD chips vary significantly in size, ranging from 0.16 inches to over 1 inch diagonally, with consumer projectors typically utilizing chips between 0.23 and 0.65 inches.

It is important to note that most consumer-grade 4K DLP projectors do not feature 8.3 million physical mirrors on their DMD. Instead, they commonly employ a 1080p DMD chip combined with "XPR" (pixel-shifting) technology. This method leverages the extremely high switching speed of the micromirrors—each mirror can reflect light to produce four distinct pixel positions within a single frame, thereby achieving an effective 4K UHD resolution.

Looking ahead to 2026, three key innovations are set to advance consumer DLP projectors:

1.  Enhanced Controller for Unprecedented Speed 

Texas Instruments has introduced the DLPC 84 series controller, enabling significantly faster operation of DMD micromirrors. This advancement delivers three major performance benefits:

• Support for 4K/120Hz and 1080p/240Hz high refresh rates.
• Ultra-low input lag, reduced to below 1 millisecond.
• Support for Variable Refresh Rate (VRR) technologies, including AMD FreeSync certification.

2.  SST Pixel Technology Raises the Brightness Ceiling 

The new SST (Small and Strong Temporal) pixel technology employs a robust 5.4-micron pixel architecture. This more durable design can withstand higher light throughput, making it particularly suited for powerful laser light sources. This paves the way for future home projectors reaching 5,000 to 8,000 lumens.

Simultaneously, laser sources offer more concentrated light than bulbs or LEDs, minimizing light spillage and significantly enhancing contrast. Specifically, RGB laser systems enable extremely fast and precise brightness control, deeply dimming dark scenes while maximizing highlights for a dynamic contrast ratio exceeding 10,000:1.

Smaller 4K Chips Enable Higher-Quality Mini Projectors

TI has also developed a 4.5-micron pixel architecture—the smallest digital micromirror to date—enabling a compact 0.39-inch native 4K DMD chip. This miniaturization allows for smaller, more cost-effective 4K projectors. In the near future, even portable and battery-powered mini/micro projectors will be capable of true 4K resolution.

Through these innovations in brightness and laser longevity, transform projectors from devices confined to dark home theaters into versatile displays.
