Strength is one of the most important properties of cover glass. In this study, fracture analysis is used to classify the breakage mode of cover glass into four typical modes. Moreover, the mechanism and evaluation method of each mode are investigate

Recently, thinner cover glass is required, therefore to prevent fracture becomes more important. Sandpaper Ball Drop Test was newly established to evaluate front-side-origin fracture. It was found that CT and glass thickness are important parameters

Recently, thinner cover glass is required therefore the glass strength is more important. It was found that surface polishing after chemical strengthening improved surface strength. In chemical strengthening process hydrogen enters the glass surface

It is shown that Potential Induced Degradation (PID) can be prevented by using chemically strengthened glass as module cover glass in this paper. While several factors are considered to be the causes of PID, migration of Na ions from module cover gla
