Cam in my work plane a couple of the digital displays are like that at night time, even with the dimmest setting they are still bright ... I took some static cling window tinting and cut it to fit the face of the display, works great and it can used over and over again.

I don't know if that would work with your application or not but it's a thought, also that tint comes in various colors and shades so it can be matched fairly easily.
