I do this a lot with older Seiko digital watches.

One layer is a polarizer. The polarizing lines decompose due to UV light over time. After removing the outer sheet of polarized film take your new sheet of polarized film. Rotate above the lcd panel while it is on until you get the best contrast. Mark the orientation, cut to size keeping the high contrast orientation and place over the lcd.

In retrospect, Joe Horn did a presentation on the polarizing orientation and their inconsistencies in orientation at HHC2008 HHC 2008 photos.

Wearing a polarized sunglass will cause you to orient the calculator display so that you can read it!

Cheers, Geoff

2008 was my first HHC meeting.
