Actually, you can fix this problem pretty easily... just put a piece of quarter wave plate filter over the display, and you'll be able to read it...since that will "de-polarize" the display. This is how "circular" polarizers that are used by modern digital and autofocus cameras work. You'll have to play with the orientation of the quarter wave plate a bit to get it to work, but should be able to get the display so that you can read it with your polarized glasses on.
You amaze me sometimes with your knowledge base. Have you ever thought of getting on the Jeopardy quiz show?
