STRENGTH

- Warranty the quality of workmanship, The world’s widest width master Roll

- Full covered prism film production line with owned technology

- Secured Large scale size of High-Accuracy and Precision patterning technology

- Specific technology know-how, phase different Wave, Tilting, Horizontal film processing

Coreoptix aims to encompass the pursuit of

customer satisfaction and commercial success

within a framework of environmental, social

and economic values

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

: Provide requested angle of master molds

: No need to cut by typical cutting method.
