Thus something as a 'High-Definition' LCD module exists ?

    I've been thinking of designing a small portable LCD device that takes
    High-Definition video (720P / 1080P) as an input (preferable from a HD-
    SDI signal)

    I've been searching around but i realy don't find out if there is
    something like a HD LCD module by itself ? If people speak of HD, thus
    this apply to the physical LCD itself, or thus it just mean that more
    data is displayed on a regular (bigger) LCD ?

    I imagined that the LCD itself had smaller pixels, so giving us more
    resolution. But if a look at the major manufacturers (Hitachi ea) you
    only find the LCD modules with resolutions we've seen for years (ea
    320 x 240 on a 5.7 inch)

    Offcoarse i see that with the same pixel size, you can display more
    pixels if you're screen is bigger..

    Just don't see how you display 1080 horizontal pixels on lets say a
    5.7" LCD.

    Do i miss something ?

    Just don't see how you display 1080 horizontal pixels on lets say a
    Not much, but there is a 6.5" 1024 x 768 TFT from NEC -
    NL10276BC13-01C .
    I saw Avnet list it (non-stock, though) at $350 for sample quantities.
    There is a nice 800x600 display by Gi Far from Taiwan, gifar.com.tw .
    It is an 8" display or so, but has a much smaller outline than similar
    (183x141 IIRC vs. 203+ for the rest, all sizes in mm); much cheaper
    than the XGA NEC and stocked.
    By far the most popular resolution for the 6" or so sized displays is
    800x480 - WVGA, as they seem to call them (Wide VGA). I can locate
    a number of them - at Gi Far included - but I also see a number of end
    products - tiny TV-sets, video players etc. - using such a display at
    local store around $100.

    Sanyo-Epson do a 7.1" 1920x1080 panel, I'm not quite sure what the point is
    on something that small though.

    Maybe not much use in a consumer application, but could be usefull for
    broadcast profesionals/diagnostics etc..

  5. Well, that all depends on where the thing is mounted, and how its light
    output finds its way to the eye. Projection systems, digicams and
    head-mounted displays have different different requirements than your
    average TV or computer screen.
