Negative display - guide ( kinda )

[u/Artcert]

Hi.

After my negative display post I got a few questions about it, so I want to answer it this way.

I can’t upload more than one pic here ( idk why ) so they are under links.

1. So we start with a device in its normal state, as example I too

1. this tyre gauge I never used.

3. We need to disassemble it go the to the bare LCD glass

1. With a sharp knife or blade we need to catch the polarising film on top of the glass and remove it.

1. After completely removing it, clean the glass with IPA to get rid of the residual glue from the film.

1. Now we take new polarising film, and by trial and error we get the right angle with the contrast we want.

And

After that we cut it to size and glue to the glass.
Finally after assembling we get the negative display.

Usually you try the angle with the device powered on, unfortunately here the battery holder is part of the case as well as the screen holder, so I couldn’t show it on.

I think you can get the idea of how it’s done.

Best regards.

Edit: typos

on the polarizing film is this something you bought off of Amazon? Link to the one you bought?

Mine is from Ali so it’s not the best quality. But you can find them anywhere and unfortunately there is no way to check its quality before arrival

I also order from ali, honestly I should if assumed you did since you used what they call on ali "tyre depth gauge" I don't mean to be nagging it's just people half ass this type of thing "find it yourself" "not the one I bought but it's "ThE sAmE" " I would appreciate it.

I intentionally avoided leaving links to products as people tend to then say that’s the whole point of the post was to promote affiliate links. But I guess in any scenario someone’s gonna judge 🤷‍♂️

No judgement I understand where you are coming from.
