The supply vessel I work on has the Integrated Bridge System with Radar, ECDIS, Conning and everything else on about 19 touchscreens (large and small, fwd and aft stations). I have to say, although nice and pretty, it is a real pain at night. LCD screens are backlit and, unlike the old CRT type, when dimmed they still produce too much light. On CRTs, where there was black on the screen, there was no light. On the LCDs there is still light produced behind the black. You have to dim them down to the point where they become unusable in order to see on a dark night. Personally, I turn the screen all the way down, except for the radars which are dimmed as low as possible, and routinely turn them up for info and situational awareness.
