touch screen display working principle.The other cost of the capacitive method is: the outermost layer of ultra-thin glass is very good in anti-scratch performance under normal circumstances, but it is required to be manufactured under vacuum in the process because it is afraid of hydrogen, and even a little hydrogen will combine to form an easy The fragile glass is a small hole when you tap it lightly during use. This is fatal for capacitive touch screens: the area around the hole with a diameter of 5cm cannot be used. The actual vacuum is impossible. This extremely thin layer of glass has a 5% probability of encountering a product with holes.
