Step 7: Reassemble glasses and enjoy!

Finally assemble the glasses and you are ready for some fun!
People might think you are crazy, staring at a blank white screen wearing sunglasses!
But I guess that makes it even more fun!
<p>can it work tft moniter</p>
<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>
<p>It WILL NOT work on LEDs, TFTs, oLEDs, CRTs, or DLPs. It has to be an <br>LCD screen (Liquid Crystal Display), because the crystals work with <br>polarized light &amp; a polarized light filter (the film).</p>
<p>Come on. TFT and LED are both LCD.</p>
<p>I take apart &amp; fix this kind of stuff all the time for a living. An LCD monitor or TV may have an LED backlight these days instead of the older florescent backlighting of a few years ago, but it's still an LCD display, regardless of what kind of light is behind the display. A true LED, oLED, &amp; TFT display does not use liquid crystals found in LCD displays &amp; do not have a backlight behind the screen. They use a different technology entirely, so polarizing the light or using a polarized light filter wont make any difference. With oLED, LED, &amp; TFT, displays, every pixel is a tiny LED that gives off it's own light &amp; color. With LCD displays, the crystals &amp; the polarized light filer, allow or block the light to shine through from a light source behind the screen. This will only work with LCD technology, don't ruin your oLED or LED screen just because some troll here likes to see people destroy their screens. Believe me, it won't work unless you have an LCD screen. If your screen is backlit by LEDS, it's still an LCD screen, not an LED screen, regardless of what the sales people said when you bought it. Likewise, don't screw with a plasma TV either. They don't use LCDs or have a backlight either. Just like true LED displays, each pixel is it's own light source, &amp; there is no backlighting or polarizing.</p>
<p>Nope, still wrong, sorry. TFT is a type of LCD screen. LED typically means LED backlit LCD (but is a terrible name). Both of which will work with this. I have _never_ seen LED screen refer to anything other than LED backlit LCD (well, for monitors at least).<br><br>OLED (the O is capital) will not work, and is the only display type you listed that every pixel is actually an LED itself.<br><br>if you want to provide a source saying otherwise, I might believe you, but right now, you're wrong.</p>
<p>I really don't know who is correct, but respectfully I was left with LOL when you demanded the party you challenged to supply supporting references, when you supplied none in your original challenge comment.. I suppose one shouldn't expect reliable informative comments in many internet comment sections</p>
<p>hahahah so true!</p>
<p>spend 1 minute googling the things I said and the things she said. you'll easily find sources that back up some of the claims, and you won't find sources for other claims. Take a guess which category the source I was asking for falls under&hellip;</p>
<p>LED as light source for an LCD display - yes, it will work.</p><p>Straight LED display (e.g. organic LED, old 8 segment calculator LED display or the other technologies Betty P3 listed) it will not work because those displays do not use polarized light.</p>
<p>I find that the 3D glasses I got already filter the light, I can see the screen... If I tilt my head sideways. :P</p><p>But I have a problem. all these images show clear images, or minimal blur. The screen is really blurry for me unless the polarizing filter is right up against the screen.</p><p>Can anyone help me on this?</p>
I think this needs 1 more hack to be really useful.<br>We need to figure out a way to feature an image on the white screen that gets filtered out by the glasses.<br>For instance, if instead of a white screen, anybody without glasses who walked into your office would see a spreadsheet, but with the glasses you wouldn't see the spreadsheet.<br>Too complex, or is it a possibility?
<p>Print a full screenshot of the spreadsheet and taskbar onto a piece of thin, clear plastic. Convince people you can only see well with black and white, so you can make it a real high contrast print. But make sure any lines are thin. Apply this to the LCD, taking care to remove bubbles. Tehn jsut get uesd to seneig waht it looks lkie knid of srecwed up. The brain is amazing at adapting, and there is a good chance you read the last sentence naturally. Look again ^^.</p>
<p>XD do you read Cambridge research? If you raed any setcnene with the lteetrs gnoe arwy, tehn you can sltil raed it if the frist and lsat ltteres are in the smae palce as bofere.</p>
<p>I know that but you cant read this:</p><p>sw y cy pe on ts we.</p>
<p>Full words please. Then I will translate it.</p>
<p>Nveer raed Cabmidrge Rseaerch brefoe, but I saw tihs smoehwree and hvae uesd it to dmeontrstae my piont a few tmies.</p>
<p>Yea, it is pterty good at gtnietg a pnoit arcsos</p>
Wow that's actually not bad. Might work.
<p>The brightness would have to be kept low as well to avoid drowning out the image of the spreadsheet with light.</p>
That is a great idea, although i don't believe it can be done. You could maybe put a standing image, but then that would conflict with the image on the screen
<p>Won't work. The crystals in a Liquid Crystal Display polarize the light to one direction or another, depending on their orientation, but doesn't actually block light. But when that polarized light shines through a polarized light filter (the film or glasses), it shows black or white depending on the orientation of the crystals or the filters. Without the polarized filter it's not possible for any image to be seen. The film he removed is a polarized light filter. So basically, he transferred the function it does from the screen, to the glasses. No matter were you place the filter, it will still polarize the light.</p>
<p>if you used round frame sunglasses you could adjust polarization </p>
Well, in a sense you are right. However, what we were talking about was pure steel. Steel CANNOT scratch glass. You were talking about alloys, not steel. Point taken, a utility knife can scratch glass though. Also, you mentioned Chromium being added. That was a little ignorant seeing as Molybdenum and Carbon are the real ones that do the job. And a buck knife having vanadium, well, you mentioned the toughness of vanadium. So you mean that your buck knife is pure metal spermicide? Interesting thought. You're arguing with a chemist.
<p>Yay, finally, someone who's found a use for my memorising the periodic table.</p>
The periodic table has a lot of secrets. Check out nitrogen. It will not only suffocate you due to lack of oxygen but also steal your reserve oxygen supplies, so an ordinary person will die in about 1-2 seconds of breathing in. It will feel normal too, because your body only checks that you breathe in air, and breathe out CO2. Also, thanks MH9 and ashery.
<p>O.T. So why isn't it used in gas chambers?</p>
<p>Am I a forensic chemist? No. I really have no idea. Maybe there are chemicals that kill faster, or maybe they want their death row to suffer first. I have no idea.</p>
<p>I do know most gas chambers use hydrogen cyanide, which literally suffocates a person, better than water or a wet towel. However, nitrogen asphyxiation has been avoided twice, although more accurately postponed. Maybe the government wouldn't want to take that chance.</p>
<p>I like this chemist....</p>
Does anyone know if this is possible with a laptop screen?
<p>It needs be a laptop with an LCD screen. My initial hunt to find such a thing came up empty but if one is found I'll bet I can do it and probably will.</p>
<p>I don't suggest you sacrifice a laptop. I will work, but its better an old monitor so that if anything goes wrong, its just a sacrifice for curiousity rather than sacrificing a laptop.</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>it depends on the orientation. it will work only if your glasses coincidentally have the same orientation as the polarized film of the monitor.</p>
<p>That would just add to the awesomeness ... looking at a white screen, with sunglasses, with your head sideways. </p>
<p>Or just turning upside down in your chair at the local caf&eacute;.</p>
<p>There's no coincidence if you plan... put the film on the monitor in the orientation needed to work with your sunglasses.</p>
<p>you can try. polarized films and glasses works in the same way. but glass are great built quality.</p>
<p>Might there be a way to work this into a laptop that has an LCD display? That's what I'd like to take to the coffee shop!</p>
<p>So now we have people walking around (seemingly) talking to themselves, and now we'll have people starring at a blank screen and laughing occasionally. ;-) </p>
<p>Imagine a man walking by, laughing and saying &quot;Yea, you're right. What about you John?&quot;. He goes intoa caf&eacute; and open a blank laptop and starts, well, idk......</p><p>Most will think he's crazy. Such a lark! Plus, for them teens, their moms won't be checking if they are doing their homework (in the digital world)</p>
That was exactly the image I had of me with one in a coffee shop. What a hoot that would be! And bloody useful too. I just don't have the skills to dig into a laptop display and do surgery.
