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

Question

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 ?

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 devices (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 the local store around $100.

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

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.
