This video shows you how to create a secret LCD monitor. The first time I read that you could do this, I just had to try. Before you attempt this, please note that I’ve only tried this with an LCD monitor. I don’t know if it will work with any other type. Also, it may not work with certain LCD monitors.
Also, the results may not be as good as the results I got. I recommend doing this project with a monitor that you don’t care about losing.The results are amazing. If you are going to try and make your own, there are a few things to keep in mind. First, I would recommed using a monitor that you don’t care about. I bought mine from a pawn shop for $20 dollars.
Once you remove the polarized layer, you’ve pretty much made the monitor useless as to normal use. If you are good with repairs and that sort of thing, I’m sure you could buy a replacement filter to fix the monitor. So basically, just make sure you are ok with modifying whatever monitor you’ve chosen to use for this project.via(brusspup )
Most LCD monitors have an antiglare layer “attached” to the polarized layer and both of those layers are glued to the hard surface of the LCD. So you may see these extra layers as you are removing them. Next you want to grab some glasses. I used a pair of the 3D glasses you get at the cinema. I never throw them in the recycle bin :). Anyway, you can open these glasses up and remove the “lenses”.
Before you cut the shape, make sure to note the proper angle of the polarized sheet with the monitor. I had to turn my sheet 45 degrees to get the correct angle. So when I traced the lens shape on the sheet, I turned the sheet 45 degrees and cut them.So now you’re ready for action. If you hook your monitor up to a computer and put on your glasses you should be able to see the screen just as normal.Anyone standing behind you will only be able to see a blank monitor.
