There are two polarizers, one on the front, which is transparent, and one on the back with a reflective layer on back. They are installed 90 degrees from each other, i.e. one rotated 90 degrees w.r.t. second one. Both are required.
It can be a guess at times to know which orientation a particular polarizer is in. I like to order a sheet large enough to cover the screen in either orientation so as to not be caught out by the sheet being too small in the correct rotation.

Recently acquired Model 200 (my first one!) No life on the screen as yet, not one pixel’s worth. Keyboard is good (at least I can get a BASIC program to beep on every keypress, and so I surmise that the main board is mostly functional.) The screen however is unhealthy-looking. The rear polarizer reflector Looks to be shot (dark shadows in photo), and so I’ve ordered replacement film. But the front of the display has what looks like a vinyl “screen protector” which is bubbled up from the glass (bright streaks in the photo) all around the metal bezel. I’m curious as to its function? Anti-glare? I haven’t seen it on any of the smaller ModelT screens. Waiting on a backup battery, and capacitors before I go back at it, and I’m wondering what use my multimeter might be in searching for data (or even just power) going to the display board. Not sure where to probe. Cheers Sean By the way, anyone seen this? I got the NEC game to load, but no luck yet with the M100 version. http://inufuto.web.fc2.com/8bit/guntus/
