Sapphire Film on Plastic

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

The technology has extended to plastics (e.g. PMMA) and the deposition process uses standard industrial mass production equipment. The surface hardness can be double the hardness on PMMA – 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: >90%
  4. Industrial Roll-to-roll (R2R) process
  5. Manufacturing cost effective

 

Application:

Flexible Display, Solar Panel, etc.
