High Contrast Linear Polarizing FilmHigh Transmission of Unpolarized Light from 400 – 700nmExcellent Extinction RatioAvailable in Various Sheet Sizes for your Customized UseGreat for experiments and learning Physics. The sheet is 0.2mm thick and 8.27" X 11.69" (21cm x 29.7cm), IMPORTANT(!) please note that on both sides there is a protective film sheet. You have to remove it gently before use. Once removed, the polarizer sheet will be revealed, clean and smooth.
Instead of watching a 17 minute video, here's a text instruction:
Note: The removed polarizer foil will be unusable for the glasses. That foil is what's responsible for the monitor being glossy or matte and the picture will be blurry unless you hold it directly against the panel. The glue is also difficult to get off (I tried WD-40, brake cleaner and gasoline and my foil is still sticky)
Removal with a knife:
Some people (including the person in the video) remove the foil using a knife. Don't do that. There's a chance you damage the display panel with the blade or slip off and cut yourself because cutting the polarizer requires a lot of force since it's much thicker than you would think. It's difficult to feel when you hit the glass below. It also takes longer than dismantling the panel.
