FEZ displays visibility outdoor?

Hi.

We are brainstorming about a prototype a customer asked us to build that should have a display very well visible in outdoor environments.

Is there any difference from this point of view among several “stock” solutions in GHI catalog?

Thanks!

Usually this means a one color display or OLED. TFT Displays offered here may work outdoor, but like any phone’s display it is not “very” visible
