interactive touch screen icon.OGS technology is to integrate the touch screen with the protective glass. The ITO conductive layer is coated on the inside of the protective glass, and the coating and photolithography are directly performed on the protective glass. Due to the saving of a piece of glass and a single bonding, the touch screen can do more Thin and lower cost. At present, domestic mobile phone brand manufacturers such as Tianyu Hornet 1st , Gionee Fenghua, and Xiaomi 2 have all adopted OGS technology. However, OGS still faces issues of strength and processing costs. Because the OGS protective glass and the touch screen are integrated together, it usually needs to be strengthened first, then coated, etched, and finally cut. Cutting on reinforced glass in this way is very troublesome, with high cost and low yield, and causes some capillary cracks to form on the edge of the glass. These cracks reduce the strength of the glass. The current lack of strength has become an important factor restricting the development of OGS .
