That display looks like a pretty typical 20x2 negative character LCD. It's white on black so one option is to find one with a brighter backlight. Another option is to change to one with an RGB backlight. I buy a lot of stuff from Adafruit, which has them but not in a 20x2, only in a 20x4 and 16x2. At least that way you could tune the color perfectly. Of course, this way you would have to add a circuit to drive the backlight, although you could still use the processing portion of the Zeitronix display. I believe LCD character displays tend to almost all use the same controller chip (HD44780).My approach was the OLED screen, both for it's color and for readability and small size. We will see how it looks once mounted. I'm still on the lookout for the best display. From what I read, transflective LCD may work well in sunlight. There are also some other technologies that look promising if color is not a requirement, like this one, although it's small like my OLED.Edit: it looks like the negative character LCD displays may be more difficult to view in sunlight, so a positive display may work better. They don't look nearly as nice though, IMO.
