brightness and contrast ? What are you using ?

For what module?

All of the modules (size & lcd type & backlight color) all have different optimum brightness and contrast levels.
It also depends on the normal viewing angle.
Temperature can make a difference too.

I find the optimium for that module to be around 63% contrast, but that can change depending on normal viewing angle.
Brightness is up to you...

CFA-631 (white on blue): 10% B, 30% C
CFA-632 (yellow on black): 20% B, 60% C
CFA-633#1 (black on yellow): 50% B, 25% C
CFA-633#1 (black on yellow): 40% B, 40% C
CFA-634 (white on blue): 100% B, 80% C
CFA-635 (white on blue): 50% B, 50% C

I set these up so that I can get a reasonable picture for the User Screen Forum. Also, my 634 is quite old. A newer one might require a completely different set of values.
