The requirements for displays in modern smartphones and tablets include thin, lightweight materials that look good and are resistant to harsh handling. These handheld displays use the toughest glass available (e.g., gorilla glass). Although this glass offers extremely high scratch resistance, it is still vulnerable to breakage. Therefore, displays that must be both unbreakable and lightweight are made of polycarbonate.

 

Scratch-proof smartphone displays made of polycarbonate

Thanks to a Plasmatreat surface coating applied with a low-pressure plasma method, polycarbonate can now be used to manufacture displays for hand-held devices like cell phones and tablets. Without treatment this material is susceptible to scratching, but after depositing a plasma coating inside the chamber, it is transformed into an ultra-hard surface that is virtually scratch-proof.

 

Handheld displays made out of glass are quite vulnerable to breakage.
