Finally you can do something with that old LCD monitor you have in the garage.
You can turn it into a privacy monitor! It looks all white to everybody except you, because you are wearing "magic" glasses!
All you really have tohave is a pair of old glasses, x-acto knife or a box cutter and some solvent (paint thinner)




Here is what I used:
an LCD monitor of course
single use 3D glasses from the movie theater (old sunglasses are just fine)
paint thinner (or some other solvent such as toluene, turpentine, acetone, methyl acetate, ethyl acetate etc)
box cutter (and CNC laser cutter :) but that you don't really need, I'm sure x-acto knife and a steady hand would do just fine)
screwdriver or a drill
paper towels
superglue

Step 1: Take the monitor apart

Find an old monitor that you are willing to sacrifice.
Take off the plastic frame by unscrewing all screws from the back.

<p>Dude, your work has been featured on Ifunny!(or just someone that stole it from here)</p><p>http://ifunny.co/fun/AtYIdyGV?gallery=shuffle</p>
<p> Wow - this is definitely a super spy cool idea.</p>
<p>This is genius to say the least.</p>
<p>yaaaaaas i made it!</p>
<p>Awesome man !! Im going to try this...</p>
<p>Can you do this on an oled screen?</p>
No, it has to be LCD.
<p>dat reaalllll coool! im gonna try it!</p>
<p>Oooh. This is really cool. I am really debating on doing this or not; Does the monitor appear as clear and sharp as before? Thanks :)</p>
<p>It does if it is glossy. If the screen is matte you would need to remove the anti-glare film for it to be as sharp as new. You could also buy a polarizing film from Amazon. The one I used had an anti-glare film, which I had to remove.</p>
<p>Thanks! :) And seriously WELL DONE on winning!!! :D</p>
<p>Beautiful!! How long would it take to make this, and what is the estimated cost for the project??</p>
<p>Genius!!! I thought this was totally fake until I saw the video!</p>
<p>this idea is awesome , but I'm not brave enough to do this :(</p>
I can't remove the polarized film from my monitor...
<p>I made it, and here is the result - https://www.youtube.com/watch?v=JK06NgHVoe8 amazing Instructable :-) </p>
<p>Nice idea! One question though, I have the exterior layer peeling off with ease, leaving a nice glossy film layer on the monitor lcd. With difficulty, the glossy display can slowly be picked off in little pieces, revealing a nasty glue ridden surface. So, the glossy screen that comes off in little pieces is the polarized film? And how do I remove it with greater ease? Any input would help. Thanks.</p>
<p>Put a few wet paper towels on it before trying to peel the thing off and let it hang out for a day or so making sure the paper towels stay damp. The whole thing will peel off in one big sheet.</p>
<p>Can you use polarized sunglasses instead of putting the polarized film in the glasses?</p>
<p>I would really like to know as well. I have polarized sunglasses that I'd rather use than go through the trouble of making some. But also, it would mean that others with polarized glasses could also see your monitor. </p>
<p>you can try. polarized films and glasses works in the same way. but glass are great built quality.</p>
<p>Awesome!!!! COOOL!!! What makes the screen white? The paint solvent? Or removing that layer of anti-glare?</p>
<p>Fiz o teste, com o material retirado do monitor ficou bem ruim a qualidade de visualiza&ccedil;&atilde;o, somente se eu colocar o &quot;&oacute;culos&quot; bem pr&oacute;ximo do monitor pra ficar com uma qualidade boa, a uns 10/15cm j&aacute; fica ileg&iacute;vel... </p>
<p>provavelmente as duas folhas -a anti-ofuscante (?) e a polarizada- est&atilde;o grudadas. coloca elas na &aacute;gua quente e a&iacute;, com cuidado, tenta separar as duas.</p>
<p>Hey I need some help. So I removed polarizing filter, and removed the glue from the screen.The Glasses work but only when there up against. Any farther then that it's burly. Anyone know the problem? </p>
<p>Yes, you have the two pieces of film stuck together. The Anti-glare (clear) and the polarizing (gray). Put the piece of film in hot water, and wait for the water to cool, then carefully!! (I cut my finger on the edge) peel the two pieces apart. Tada!</p>
<p>Is this possible to do on a laptop?</p><p>I SO want to be that crazy local girl at the cafeteria, working and staying bussy looking at her white blank screen all day long.</p>
For all you people reading today, the answer is yes. Just did it to my hp pavilion-g7
<p>LOL Julie that would be pretty epic!!!!</p>
<p>This is pure genius! Not exactly a practical invention, but impressive nevertheless.</p><p>How did you come up with this idea?</p>
I found out how to remove the polarized sheet from the anti-glare sheet if they're attached to each other. What you do is put the films that you obtained from the monitor in some hot water. Leave it in there until the water cools and the sheet should curve. Pick at one of the corners or edges until you can manage to peel off the polarized layer. Only the area that was submerged will be able to be peeled off. <br> <br>I hope this is helpful
<p>I love you so much it's probably a crime.<br><br>Thank You!</p>
<p>Thanks man, was wondering how to get the films separated. </p>
<p>Wow, thanks! Will definitely try this! I just recently got a little 14&quot; VGA monitor for $20 at a thrift store and I was planning on trying this (the Instructable) out on it when I have some spare time. Thanks for your comment!</p>
Hey bud, just wanted to say a big thank you. I can confirm, if your polarized sheet is seemingly bonded with the anti-glare layer, microwave a mug of water for 2-3 minutes and let the cutouts soak for half an hour or so. <br> <br>The two layers will separate like stickers from a sheet :)
<p>yes it works for all LCD, cellphones and LED's. and TFT screen too. I did in my child hood with small &quot;digital calculator&quot;. None of my friend could use my calculator, But was master then in making calculations using the same calculator</p>
