Cover glass,cover lens for optical bonding
Processing
When it comes to optical bonding,it requires lower warpage between cover glass and LCD panel,any unacceptable gap out of tolerance will infect the bonding and whole sensors.
Chemically strengthened can control the glass warpage <0.2mm(take 3mm for example).
While thermally tempered only can be <0.5mm (take 3mm for example).
Central stress :450Mpa-650Mpa,which makes glass have better performance in scratch resistant.
