Lit Trick: How to make an invisible monitor. ( Or Private monitor)

The title sounds quite interesting, doesn't it ? But is it possible ? Will I have to buy expensive stuff ? Well here's the asnwer - No you don't, In fact, the required materials are almost minimum. But before we proceed, what is this 'invisible' monitor ? How is it private ?

To start, the world is full of LCDs isn't it ? That is, Liquid Crystal Displays.  Now, what happens in such a display is varying amounts of a fixed-intensity white backlight is passed through an active filter. The red, green and blue elements of a pixel are achieved through simple filtering of the white light. This filter is called the Polarizing filter. In absence of this filter, the picture on the screen appears white to the human eye due to unfiltered white light. And this is exactly what we do.

Read on to know what you'll need and how to do it.

Materials 

•    LCD Monitor ( Preferably old )
•    Screwdrivers and similar tools ( Depends on your monitor )
•    Some Paint Thinner / Turnpin / Petrol along with Tissues or cloth. (Optional yet highly               recommended )
•    Glass frames.
•    Polarizing film

Method

Step 1 :-  I'm not really going to explain how to disassemble your monitor because, frankly, I know it wont help you. Because every single monitor is different. So instead, I suggest you to find your monitor's model name and search for a tutorial. What we need is the display in our hands,

Step 2 :-   Once you have the display in your hands, its time to get to work. Get a knife/blade or a flat screwdriver and start from the edges. There will be two films - the polarizing film and the anti-glare film. Strong adhesives are used for these films so it will be quite tough removing them. Work hard on it till every piece of film is gone and nothing remains on the display but glue.

 With Thinner or some remover.


        Soak it in hard tissues or a absorbing cloth. Gently spread it over the glue and press it. Be careful to avoid contact with plastic parts as some chemicals may damage it.. Wait about half an hour and then gently remove all layers. Wipe the display clean and clear,

Without a removing chemical

    Get a blade of scrape the glue off. Its quite tough but eventually the finish will be same.


Step 3 :- Reassemble the monitor. Provide input if needed but all you'll see is white screen.
             This is what others would see while you are using the computer !

Step 4 :-  This step is both easy and hard. It depends on the type of frame you have. You have have to cut out the polarizing film in the shape of the frames. You can either -

 a)          Get a frame like in the video for ultimate perfection.
 b)          Go to shop and have it done for the same perfection.
 c)          Find those old blue&red paper 3D glasses and cut it out. Then stick this film.
 d)          Do it your way.


Step 5 :-   Test it and enjoy it.
