| Summary: | 碩士 === 國立高雄應用科技大學 === 化學工程與材料工程系 === 98 === In recent years, the rapid development of LCD technology and production become
increasingly skillful, has been widely used in various electrical appliances on, and its
related components back light module and the highest percentage share of the cost of
technology low, has attracted numerous manufacturers manufacturing and R & D into
the ranks. Backlight module according to a variety of uses, and the assembly ways and
with different size, the required optical thickness and function of different optical film
in the reflective film of choice as well. It is different with other optical films the most
important point is its location in the lamp is placed below the light source directly
affected by irradiation, its temperature and UV light will affect the optical properties of
reflective film.
III
Purpose of this study add titanium dioxide to enhance the viscosity and ultraviolet
light capability. DuPont Teijin of Japan's reflective film production company for the
substrate, producing samples, samples of different thickness on the heat treatment at
different temperature for 500 hours, the weather resistance test, and XRD analysis of
the UV exposure test, discussed crystalline material, and ultraviolet light tests in the
AFM analysis, the discussion of the material between the surface roughness and
chemical composition changes.
