One correction to the article, chemically strengthened glass works by putting the outer layer of the glass in compression. In order to accomplish this, the inner layer of the glass is in tension. If you cut through the outer layer into the tension layer the glass immediately shatters; chemically strengthened glass can not be cut into smaller pieces unless the strengthening is negligible. Therefore, cover glass needs to be cut before strengthening.

Thank you for taking the time to read it! I've lived through dozens and dozens of customer projects and I was hopeful when writing this article that it would help some OEM designers to be more aware of available technology and to protect them from getting incomplete data from touch suppliers. I'm thankful that you found it interesting. Trevor
My pleasure. I find that there are many suppliers in the world who declare that they can manufacture touchscreens and touch product, but many of them create subpar product or lure unsuspecting OEMs into product that does not perform well in the end application. I'm just hoping that have a more informed customer base will raise the bar on touch solutions and will help keep designers from getting subpar outcomes. Best of luck!
