Technical information
- The view control technology by Shin-Etsu VC-FILM
- Shin-Etsu view control film is used to the mobile phone as "veil view" or as anti-reflection toward windshield and so on. By the use of silicone rubber, it is superior in environmental resistance, optical characteristic or flexibility and highly effective.
