The backlight cannot be turned off at all. Originally I integrated a photosensor into the design so the backlight could be controlled automatically, but the LCD display board I used seems to be incorrectly designed (internally) such that the backlight is permanently on. In the daytime, this makes the display hard to read. In the nighttime, it is almost blinding.

I think a solution here may just be to not support backlighting at all -- it doesn't feel necessary.

The numbers on the display can only be read from a very small angle - almost directly head-on.

The only solution here is likely going to be a new display module. Maybe E-Ink?

In bright light, the display is very hard to read. This is partially due to a combination of #3 and #4, as well as the display itself just not being very high contrast.

The plug on the bottom of the device conflicts with the bottom screw so it can't be fastened properly:
