Design of Mobile Phones Using Mineral Glass

This is a Master Thesis about the use of mineral glass in mobile phone front windows. A brief introduction to glass as a material and its behavior is followed up by our own research and investigations. We have looked at existing and unreleased phones from Sony Ericsson that use or will use mineral glass. We have also examined some competitor phones. All gathered information was analyzed, sorted and represented as a display guideline with the main purpose to avoid mistakes from being repeated in future development processes. The work has primarily dealt with the prevention of glass cracking in the fall tests. Based on our findings we have suggested modifications that would decrease the risk of glass failure and have physically modified prototypes and analyzed them in free fall tests. We evaluated the results from these tests and with research drew conclusions and recommendations.
