How Computer Screen Privacy Filters Work
Screen privacy filters are an easy way to keep prying eyes from seeing what’s on your laptop monitor. If you’ve ever wondered how they work, this video reveals it all.
If you’ve ever had vertical blinds in your home, you know that you can only look through them from a certain angle. As Linus explains in the Techquickie YouTube video above, screen privacy filters work the same way, but on a much smaller scale. Tiny blinds or micro-louvers built into the filter allow light to pass straight ahead rather than on the sides. Thanks to this, you can see what is on your screen, but the eccentric next to you on the plane is not. Some laptops now even come with filters built in, where you can turn the filter effect on and off as you wish.
Screen privacy filters work pretty well, but good ones don’t come cheap, especially if you have a large monitor. If you don’t want to spend anywhere from $ 30 to $ 150 on one, you can always create your own DIY privacy monitor .
