Has anyone ever constructed a viewing hood for using a LCD display (monitor)
in daylight? I am thinking about a full hood that would be positioned over a
screen and one would then peer into it. Sort of a truncated pyramid sort of
thingy that could easily be removed and stowed. These sort of things used to
be used on PPI radar scopes and on Oscilloscopes.

If you have done this and would be willing to share your knowledge, I would
like to hear from you. I have searched with google and could only find sites
that sold some partial hoods that do not interest me.

Any enlightenment will be appreciated.

Measure the circumference around case where you think a hood would
mount. Then look for plastic milk jugs or juice jugs or chemical jugs
with an eye for one that is close to the right size. Then cut the
bottom out and the top off to make a hood. There is a lot of room for
creativity here. If it is a slip fit try using it like that.
Experiment with paint on the interior or exterior (flat black?) to
improve light masking.

If you have to make it fit better, cut down one side (the bottom?),
punch some holes and lace it on. Or overlap the edges and hold it on
with a small bungee cord or rubber bands.

I used to work in rooms where the lighting was dimmed down in order to
use one large, unhooded, not very bright display. And there were about
10 other adjacent smaller displays of various types.

Many of the other displays had to have the intensity either turned up,
turned down, or lived with as they were if they did not have adjustable
intensity. That gave rise to a non stop procession of ad hoc hoods to
keep the too bright displays from bothering the dimmer displays and the
eyes of the people operating the big display.
