Hello everyone... I am curious about such a thing. Because I have two used XLIM Pro electronic cigarettes and there is a small lcd display and when taken apart you can see something like the pictures. And it makes me wonder if such a display can be used for arduino projects. I also noticed that on the board you can see two solders RX and TX . maybe it is possible to use this LCD or the whole module to program it to display something else on the screen...?
someone tried something like that ?
and this is a video of how it generally works.
