If you are bold enough to try definitely use a diamond drill designed for glass and ceramics and use light pressure against a flat rigid board.Glass cutter. Straight line. Snap...—the cut was OK but it introduced edge weaknesses that became a crack under stress.

I wonder if carefully and slowly using a Dremel tool with a diamond bit might lead to success. I do have some old LG and Samsung phone screens I can test it on. Perhaps submerging the edge of the screen in water while drilling/cutting/grinding (and being sure to give it ample drying time afterward, maybe with silica gel) would help.Mobile glass is chemically tempered glass and not thermally tempered - the skin of the glass is only hard so as to prevent scratching, unlike normal thick toughened glass which is thermally tempered and cannot be cut, if tried will shatter in small pieces - a chemically tempered glass can be safely cut by scoring with a diamond cutter.
That is a very interesting idea. I will look into it. Thanks again.PiGraham wrote:I wonder if its possible to sense control position through the glass. Mount rotating magnet on the front and two hall effect sensors behind.
Just a thought.
I've seen at least a couple reports of that issue. I've read about some specific pi+screen cases which can be purchased that actually seem to cause that problem.PiGraham wrote:I just noticed something about my 7" display that has been in a box of bits. The front glass has moved and no longer aligns with the display behind. It must have been on edge and sheared the adhesive under gravity over time. I wonder how much can be disassembled and whether the front glass is critical to the touch functionality (if that's needed). Maybe the front glass could be unstuck and the active display put behind a different glass that was a closer fit.
It's also possible to shape glass untempered then temper it for strength. It wouldn't be gorilla glass, but it would still be tough.
