You can finally do something with my old LCD monitor lying around in your garage. Turn it into a spy monitor! All around it will look just white screen, but not for You, because You have a special “magic” glasses.
All You need is a pair of old glasses, paper knife and paint thinner.
That’s what I used:
- of course this LCD monitor
- disposable 3D glasses from the movie theater (old sunglasses are fine)
- the solvent (or equivalents)
- paper knife
- screwdriver
- paper towels
- superglue
Step 1. Take the monitor.
Find old monitor that you are willing to sacrifice.
Remove the plastic frame by unscrewing all the screws on the back side.
Step 2. Cut the polarizing film.
Most LCD displays have a glass coating of two layers: a polarization filter for light which you should not see, and a frosted anti-glare film. We don’t need anti-glare and polarization we use in our glasses.
It’s time to take a knife and cut the film on the very edge of the screen. Don’t be afraid to press, metal will not scratch glass if it is not real dust and crumbs.
* Tip from the comments: not all monitors coverage of two films glued on some they just imposed and if you remove the protective metal edge of the matrix you can remove without cutting.
Then push the tape from the screen. Don’t forget to save the polarizing film as well remember its orientation.
Step 3. Clean the screen from the adhesive.
Once You have removed the tape probably stuck to the screen glue, go to the dirty work.
Scrape the glue with solvent and paper towels.
I found that if you cover the screen with paper towels soaked in solvent and let them soak to remove the glue will be easier. As for removing the glue, you can use any piece of plastic or wood, just scrape the glue off the screen.
Be careful, make sure that the solvent does not impinge on the plastic frame.
Step 4. Work on your monitor is completed.
