    Hi

    I am a graduate design student and stumbled upon this product while searching for ways to construct something similar for a project:


    Although the video showed me that it is indeed possible to have a working lcd screen with a hole in it, the size of the hole and the screen does not work for the project i am working on.
    I have reached out to the company but never heard back.

    So I wanted ask if there is anyone here who knows how the company in question managed to achieve this, and if it would be possible for me to do the same (I have access to various studios but not ultra tech tools)

    Best

    The idea is straightforward enough -- the LCD panel proper is already transparent. The combination of backlight, polarisers and the LCD make the display.

    If you selectively eliminate the polarisers from an area of the display, you'll restore transparency to those regions.

    Execution is where things get tricky: Those polarisers are firmly glued to the surfaces of the LCD, so doing this yourself involves the use of some potentially nasty solvents. You'd need to get fresh polarising films, cut out whatever hole you want (keeping track of the proper polarisations), and then re-glue them to the LCD panel. A good CM would be able to do this for you.

    Thank you for the answer
    But what is a CM?

    So sorry -- I had just read a lengthy article about the new iPhone, in which many references were made to the "CM" -- contract manufacturer -- so the abbreviation was rattling around in my head.

    If you're planning to go into high-volume production, the CM who would presumably make these things for you would generally work with you to construct a prototype.

    If not (or if their terms are not to your liking), you could do this manually, I suppose. I once went shopping in China, and was stunned to see a group of what looked like teenagers merrily stripping off damaged polarisers from old laptop and monitor screens, and replacing them with new ones. I don't read Chinese, but the solvent bottle had an unambiguous skull-and-crossbones on it. Presumably it means the same thing in Chinese as it does to Westerners. Of course, they were doing this in an enclosed space with no visible ventilation. I did take the opportunity to buy a few sheets of polarising film, then left quickly.

    Thank you for the clarification
    But if I'm not mistaken I would also need to strip/patch the corresponding sections of the back light and liquid crystal layers
    Is this correct?

    Most "back"lights are actually mounted on the edge(s). You would have to remove the opaque parts of the frame, of course.

    You don't need to touch the LCD itself; as I mentioned, it's transparent. You only need to cut holes in the polarising films.
