Sapphire Layer on Flexible Plastics Cover

A patented process to deposit an ultra-thin layer of sapphire on to a flexible plastics substrate;

• The technology has extended to plastics (e.g. PMMA, PI) and the deposition process uses standard industrial mass production equipment.
• The surface hardness can be double the hardness on PMMA & Polyimide (PI) film – achieving >5H Pencil Scale. Therefore by having the sapphire thin film, the display cover is more durable and less easily scratched.

Characteristics:

1. Surface hardness upto 5H pencil scale
2. Sapphire shield that can be BENDING
3. High transmission range: 84-91%
4. Industrial Roll-to-roll (R2R) process
5. Manufacturing cost effective

Application:

• Flexible Display, Solar Panel, etc.
