[NTLK] Hi there - maximizing LCD Contrast and readability in direct sunlight

[Tim Kaluza]

Hey ho!

No problem!

I'm not sure that I understood your "problem" right - the screen isn't just readable or are the pixels turning black?

What happens with a foil? Actually you can pull up the contrast button because the reflected sunlight enhances the readability in turning up the contrast. I mean Newt's LCD Display doesn't provide our eye with light. It's just that its less light than the surrounding ( the one pixel) therefore maximising the contrast should help here to, shouldn't it?

Sorry for that not simple formulation - my english is too poor for technical turns. 

Hopefully you got, what I'm talking about!

All the best!
Tim K
