Using 1 film of CES, it improves 50% luminance and 2 films of
CES crossing at right angles, it improves 70% of luminance.
CES gives maximized light source efficiency to use the prism
structure to radiate maximum light amounts to demand
destination and most of other refracted light re-reflected to
use internally.

- Optimized Cutting yield rate
- Reason of Tilt Angle
: Across right angle(90°) with 2 prism film occurs MURA symptoms
: Typical method of eliminating MURA symptoms, to use way of
cutting prism films with sudden tilt angle
- Coreoptix has own know-how with master mold Technology
