    DarkChip 4 savnet på markedet

    Er det noen som har noen forklaring på hvorfor det har dukket opp relativt få DarkChip 4-prosjektører? Chipen er jo et par år nå, og skulle gi merkbart bedre kontrast enn DarkChip 3 (25 % i følge Texas Instruments), men likevel lages de fleste DLP-prosjektørene med Darkchip 2 og 3. Og til og med noen med Darkchip 1. Er det finanskrisa som har skylden, eller er det tekniske grunner?

    Eneste forskjellen på DC3 og DC4 var vel at sistnevnte i teorien skulle kunne kjøre med litt større vinkel på speilene (i off posisjon). Etter hva jeg har forstått fungerte det heller dårlig, og dermed skiller det så og si null på de to.

    Aha. Det forklarer en del. Men da burde det i alle fall være dags for en ny chip fra TI? DarkChip3 er jo ikke akkurat en ny oppfinnelse (vi snakker vel 2004-2005?). Selvfølgelig er ikke chipen alene ansvarlig for god kontrast, men jeg har et inntrykk av at DLP-ens forsprang har krympet en god del, og at de aller mest populære High-End-prosjektørene kommer fra Sony, JVC og andre produsenter som bruker Lcos.

    Jeg fant forresten pressemeldingen fra TI om Darkchip 4:

    DLP News Center

    DLP® Products Announces New Darkchip™ 4

    New Chipset to Increase Picture Quality and Contrast Ratios for DLP HDTVs and Projector Products

    Denver, CO – September 6, 2007: DLP® Products from Texas Instruments (TI) (NYSE: TXN) today announced the introduction of a new chipset, DarkChip™ 4, that furthers the position of DLP as a leader in picture quality and contrast ratio. The new chipset is reported to deliver 30% or more increase in native contrast ratio depending upon the application. All DLP product lines, including DLP HDTVs, DLP 1-chip projectors and DLP 3-chip projectors currently feature products with various chipset iterations of DarkChip technology. The new DarkChip4 will be available in a number of products in 2008.

    “Using our current DLP chipsets, our customers have built some of the most competitive Home Theater products in the market, all with excellent picture quality,” said Lars Yoder, vice president, DLP Front Projection Business Unit at TI. “We are proud to introduce the next generation of the DLP chip for future product implementations. It will provide our customers even more flexibility for designing projectors that can meet the needs of a wide range of markets.”

    The DarkChip 4 process was first developed for the high brightness and contrast picture quality requirements of the digital cinema industry, of which DLP Cinema® is the founder and uncontested world leader. The contrast improvements from DarkChip 4 are achieved by advances in mirror design lithography and other proprietary process changes.

    DLP uses a streamlined optical system that efficiently reflects light to the screen, resulting in a stunning viewing experience - crisper whites, ultra-rich blacks and images that "pop" on-screen, making it ideal for unforgettable presentations or movies. DLP-based products are known for their native contrast ratio levels which ultimately sets minimum product contrast ratio level for all scene content. Native contrast ratio also sets the “black level” of the system.

    “We are constantly searching and innovating new ways to create simply the best HDTV experience. The better the native contrast performance our mirrors can deliver, the more images will jump of the screen,” said Adam Kunzman, DLP HDTV business manager. “This breakthrough, combined with our other innovations, vibrant colors, high resolution, clarity and digital imaging, gives our customers a competitive and unique advantage in the marketplace”.

    At CEDIA (booth #620) DLP is showing multiple demonstrations, of the capabilities of the new chipset innovation. The DLP DarkChip™ 4 Theater features a 3 chip, 1080p DLP projector featuring the new chipset producing trillions of colors combined with a native contrast ratio of 15,000:1. Additionally, there is a demonstration of a DLP HDTV with DarkChip 4 and LED illumination with a native contrast performance beyond 100,000 to 1.

    For more information about DLP technology and select product demonstrations with the new DarkChip 4 chipset, visit DLP at booth #620 on the show floor at CEDIA.
