Those displays are for direct sunlight out on the deck of a boat without any shade whatsoever. The VX cockpit has got a lot of shade, especially if the windows are tinted. Without a sunroof, you probably won't have any direct sunlight on the display's screen. Although it would certainly be nice to be able to crank it up to blinding levels if needed.

There are companies out there that retrofit extra back-lighting to standard panels plus there are a ton of raw panels out there that only speak LVDS. There is also a relatively new reflective technology for TFT displays called "transflective" which appears to make use of reflected light so the brighter the environment the easier it is to see the display.

So, tons of options, but like most things in life it comes down: Good, Cheap, Easy -- pick any two.
