Introduction
Because of rapid growth in LCD industry, Daxon integrates optical,
chemical, mechanical etc. in all respective special talents to focus
on the research and development in one of key components of LCD
display -- polarizer. Daxon endeavors to establish independent polarizer
technology and higher optotronics skills to compete with other world-class
competitors. |

— Functions
of Polarizer |
| |
|
|
|
|
Polarizer can transform
natural light to straight light. Its purpose is to make natural light
to vertical and divide the component of light, in which a portion
of rays through polarizer can pass, others are blocked. |

The structure
of polarizer is composed of PET film, PSA, TAC, PVA, WV (Wide View)
film, EVA and PET. The concise structure is shown as below: |

■ Future Trend
Since
the liquid crystal display has become a mature product, many countries
take it as regard of the next trend of display application. However,
competitors from Japan, Taiwan, or Korea eagerly last for investing
on the fifth or above generation of production lines. Obviously,
such competition will bring related key components more demands.
Therefore, Daxon actively ventures on polarizer for liquid crystal
display, especially on products such as cellular phone, digital
camera, NB, monitor, and TV. Other application of polarizer can
pay more efforts on developing it with features of anti-scratch,
anti-glare, anti-reflection to generate wider commercial market. |
