I bought some, I think it was 114 mm high, red 7 seg displays from Farnell 
to make a custom display for showing result times at a race track. I knew
it would be hard to see, so I drove them pretty hard, and when I first 
turned them on in the circuit at home, I was blinded. They were insanely
bright.
Next weekend on the track, it was a great day, the sun was on and I 
brought my new display. It was totally invisible in the sun !! You couldn't
see anything ! Not even up close.
So - try to get that fluorecent displays if possible in any way, it is by 
far the best technique. Or perhaps a 7 segment display made by ultra 
high brightness LED's could be used.
