[PLUG] 10-bit LCD panels

Some time ago  we had a discussion of 10-bit LC Display panels.

Here is some news (and a great opportunity to toot the Labs' horn :-)
apropos to that subject.  A (very, very small) part of that work was
done using Linux.

    HUNTINGTON BEACH, Calif.--(BUSINESS WIRE) via NewsEdge Corporation --

    Sharp Systems of America, a division of Sharp Electronics Corporation,
    has announced a family of new LCD desktop monitors including the
    flagship LL-T1820, which incorporates the first LCD panel in a
    commercial product capable of displaying over 1 Billion colors.
    The LCD panel, developed by Sharp Laboratories of America in Camas,
                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    Washington, sets a new standard in color imaging by displaying 10 bits
    of gray scale per subpixel for a total of 2(30) colors, which is sixty
    four times the colors displayable by a conventional LCD panel. (a)
    "The ability to reproduce a much finer color gradation sweeps away one
    of the few remaining areas in which a CRT has shown superiority over
    an LCD in professional applications such a pre-press and medical
    imaging," explained Greg Nakagawa, senior vice president and general
    manager of Sharp Systems of America. "This innovation raises the bar
    for LCD displays and demonstrates Sharp's leadership in LCD
    technology."

    LL-T1820
    The Sharp LL-T1820 is the ultimate 18-inch LCD monitor. It features
    the Sharp ASV technology LCD panel that provides a superior 25 ms
    response and super-wide display angles of 170 degrees both
    horizontally and vertically. A unique 10-bit per subpixel gamma
    correction table maintains a linear gray scale while delivering the
    maximum image data in very dark and very light areas of the image. The
    LL-T1820 employs Sharp's Ultra High Aperture (UHA) technology for
    reduced power consumption and improved brightness (220 nits), as well
    as AGLR, a multi-layer surface treatment that reduces glare and
    reflection to less than one-third that of a conventional LCD. With a
    slim bezel width of only 17 mm, the LL-T1820 is ideal for
    multi-monitor applications while its dual DVI inputs permit the most
    flexible configuration in new and existing installations. Furthermore,
    its ability to pivot to the portrait mode reduces or eliminates
    scrolling for page-oriented applications thus improving productivity.
    The LL-T1820 is available in black or white for an estimated street
    price of $1299.

    LL-T1803
    The Sharp LL-T1803 18-inch LCD monitor brings premium performance at a
    value-oriented price. With its 220 nit brightness, 400:1 contrast
    ratio, and analog or digital (DVI) inputs, the screen performance is
    exceptional. Furthermore, the Sharp LCD panel used in this monitor has
    an extremely fast response time of 25 ms making it perfect for
    displaying TV or DVD (TV tuner card required in the computer) and high
    speed games. The LL-T1803 also features a long-life (approximately
    50,000 hours) backlight, which is 2 1/2 to 3 times the life of a CRT
    monitor, making this monitor an excellent investment. Available in
    May, the LL-T1803 has an estimated street price of $949.
    LL-T1520
    Echoing the super-slim design of the LL-T1820, the LL-T1520 is the
    premier 15-inch LCD monitor available today. Featuring the Sharp
    ASV-technology LCD panel that provides a superior 25 ms response and
    super-wide display angles of 170 degrees both horizontally and
    vertically, this monitor produces exquisite graphics and sharp text.
    The AGLR coating maintains superior contrast by canceling glare and
    maintaining velvety blacks even in brightly-lit environments. A pair
    of speakers for multi-media applications is integrated with the bezel
    so unobtrusively, that one can barely tell they are there. The
    LL-T1520 is available in white or black for an estimated street price
    of $499. Availability is scheduled for May.

    LL-T15G1
    The price/performance leader in 15-inch LCD monitors is the new Sharp
    LL-T15G1. Its high brightness (260 nits) and high contrast ratio
    (350:<stock_info.asp?ticker=1>) result in a flicker-free image of
    extremely high quality. Auto synchronization and auto gain controls
    simplify optimization of this monitor for the best image from a PC or
    Apple computer. A cleverly designed base folds up to expose a
    VESA-compliant hole pattern for wall or arm mounting of the LL-T15G1.
    The need to remove the base is thereby completely eliminated. The
    LL-T15G1 also features a backlight with very low power consumption (29
    watts) and extremely long life (typically 50,000 hours), making this
    monitor less expensive to own and use than a CRT monitor of similar
    size. The LL-T15G1 is available in May and has an estimated street
    price of $429.
