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 to have 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

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

i did this thing. But i have a problem. i you put polarized film further, the screen is getting cloudy. it means it is not clear. In your movie it is so clear. How can we fix this problem?

Good afternoon, you can fill with any type of lens?, Not to worry if I damage the polarized. Thank you.

Does this work on the dell inspiron mini 10 Nickelodeon edition.

that sounds like a very bad idea, do not take your net book apart.
Hey is the polarized film supposed to be SUPER hard to get off the screen? I've been trying for hours with no luck :/

I have read the comments and the "creator" said that it would work on any lcd screen but I have also read in the comments that some lcd screens have their "film" like almost glued on or something.

Cool that is a good idea

This is something that i should try at least once in my life!!
Would this removal allow for UV to pass thru the screen? I am working towards a 3D printing process using DLP projectors. If I were to construct this and backlight it with uv lamps would I get passthru?

I don't think so. I believe the glass blocks most UV light.

I've removed the film from the monitor (works great!), but the polarized film and anti-glare film are still stuck to each other. How did you separate them?

That is because you did not remote the antiglare film. Buy some polarizing film from Amazon and make yourself new glasses. It is going to work for sure.
Awesomesauce! :3 I'm trying to make this in half term as I want to learn electronics. It's very cute, I love it!

I'm wondering if its possible for this to be done to a laptop (specifically a Lenovo u410 that i'm using for university) There's literally no where in my school that I can sit comfortably without having someone sitting behind me possibly able to see what I'm doing. Not that I'm doing anything out of the ordinary, its just a little unsettling to me.

i have noticed that u can easily see the content on the screen without the glases if u look on the screen from the sides , is there any solution to that?
did anybody else get into this and find out that your anti-glare and polarizng are integrated? BUSTED :( anyway i think i ruined my lcd before that anyway when i look thtough the film the screen is not functioning properly. lots and blocks and lines along with the broken up display image. sad
That's brilliant, i can't imagine people watching you staring at blank monitor
Brilliant, just tried it and it works. the only thing i found was that if you wear the glasses the screen is blurred where as if you hold the glasses closer to the screen it gets clearer. is there any way to resolve this or is it just the nature of how the polarized screen works
dimovi (author)  crashapollo1 year ago
This is because you still have the anti-glare film on. Get some polarized sunglasses or buy polarizing film online, then you will be able to see the monitor from any distance.

That would only work on "anti-glare" screens, "glossy" screens do not use a polarizing filter.
kalant nicexe1 year ago
Good point nicexe, but how to find out if my screen is in fact anti-glare screen?
dimovi (author)  kalant1 year ago
All LCD screens use polarizing films, including the glossy ones.

could something like this be possible but with text on paper instead of an LCD screen?
Kind of , not like this since the polarized (dark) plastic filters out the light that the monitor gives out to create the images.

However, the same idea of using a lens to see something on a paper is possible if you were able to find some substance that can only be seen through a respective filter. For example, with black light it would be possible to see hidden image/substances on a piece of paper (think of blood ala CSI). But you would have to figure how that works through a lens instead of the light reflection. If someone experimented I'm sure they would figure it out.
I think sugar and water has simillar properties to what you want and the color (dont know how you spell it in america :P) depends on how much sugar wich could make some cool art works. The only problem is, there has to be light behind the sugar/water substance to be seen.

Will it work with that? http://www.amazon.de/Brille-Hornbrille-Polarisationsbrille-Wayfarer-style/dp/B004QNER5Q/ref=sr_1_3?ie=UTF8&qid=1324027375&sr=8-3
dimovi (author)  Meister272 years ago
Probably not. It is all about the angle of polarization, and i've never seen glasses polarized the same way as monitors.
I just tried this to see how well it actually worked, works amazingly, but my polarization film is still stuck to my matte finish film. I got my dad to drop off his very expensive sunglasses (Very unwillingly) and they work perfect as is! No tilting or anything! But they are sunglasses which makes it difficult to see indoors and what not. Any good way of getting the 2 films to separate?
Okay thanks! Next question: Will that work? http://www.tradoria.de/optik-baukasten/polarisationsfolie-330189346.html

My LCD screens film seems to have the matte finish and polarized film as one sheet. I tried a lot but i cant get them off each other.
would it work with an itouch 4g? (lcd screen)
do all screens do this or are there limitations to age/ year produced
