$80K DPI Titan 3-Chip LED Projector: ‘No Lamps, No Heat, No Noise’
'No lamps, no heat and no noise' characterize the demo from Digital Projection International (DPI) of the first-ever home theater 3-chip LED projector, the Titan 1080p LED 3D.
If you visited Digital Projection International (DPI) at CEDIA Expo 2013, you might be pining to go skiing right now. Using demo clips from the ski movie “The Art of Flight,” DPI showed the TITAN 1080p LED 3D Projector, which it says is the world’s first combination of 3-chip DLP imaging and solid-state LED illumination.
In the demo, the broad color range was apparent as DPI staff switched between the 3-chip and a single-chip projector. Using Texas Instruments’ DarkChip DLP technology, the TITAN 1080p LED 3D has an extraordinary color space available, strong black levels and a 2,000-lumen specification. The color gamut produced by a 3-chip LED display is up to two times as broad as a single-chip DLP/LED projector because the DMDs are dedicated to each primary color, as opposed to sequential display of R, G and B primary colors (as in single-chip).
“Three-chip LED means no lamps, no heat and no noise,” says Michael Bridwell, DPI’s vice president of marketing. The unit also enlists DPI’s Lifetime Illumination platform. “It also means it is virtually maintenance free. It just needs a filter change once a year,” adds Bridwell, saying the lamp-less technology equates to 60,000 hours, or 10 to 15 years, of viewing time. He noted that famed designer Theo Kalomirakis came by for a demo and was sitting directly beneath the unit and could not hear the fan at all. The projector is priced at $79,995 MSRP.

The benefits of LED illumination versus lamp illumination are widely known, including unrivaled color performance, lower overall cost of ownership, less heat and noise produced and no lamp replacement concerns. Equally as compelling are the advantages to 3-chip DLP/LED over single-chip DLP/LED displays.
But what about brightness? Though often measured as less bright than many lamp-based projectors, LED projection systems are perceived by the viewer as being much brighter than their measured luminance specifications, thanks in part to the Helmholtz-Kohlrausch effect (H-K effect). The International Electrotechnical Commission defines the Helmholtz-Kohlrausch effect as, “a change in brightness of perceived color produced by increasing the purity of a color stimulus while keeping its luminance constant within the range of photopic vision.”
In layman’s terms, the H-K effect describes a situation whereby if two color stimuli sources with the same luminance are compared, the perceived brightness induced by the color stimuli of higher purity will be higher than that of lower purity. LED illuminated projectors produce extraordinarily high color purity and saturation, thus appearing much brighter than a lamp-based display with similar measured lumen specifications.
In the projector, the RGB-based LED illumination system eliminates the need for a color wheel to produce primary colors. Instead, red, green and blue LEDs produce primary color illumination, rendering a broad color gamut and color saturation with no color wheel artifacts. Additionally, the TITAN 1080p LED 3D features DPI’s FastFrame technology to minimize motion smear.
