Abstract: 近年來,隨著Apple智慧型手機(i-Phone)及平板電腦(i-Pad)大賣,致使觸控產品的定位從高階轉換為基本功能,而各家廠商亦無不推出各式觸控產品來相互對抗,以致造成3C產品製造商百家爭鳴。然3C產品之「觸控」功能,如抗反射膜(Anti-Reflection Film,AFM)、絕緣膜、導電膜、硬化膜(Hard Coating)、抗指紋抗污(Anti-Smudge)等,皆與其薄膜整體使用之製程參數有關,且隨著觸控薄膜功能需求與日俱增,致使吾人不得不對觸控薄膜整體製程給予重視。
由於光線經過玻璃或塑膠基材(PET、PC等)介質的表面會有4%~5 %的反射率,因而造成使用者在使用顯示器時,容易受到外界光線的干擾,而看到一些衍伸變造之外界影像。此時,如能於玻璃或塑膠基材表面做抗反射膜處理,則是解決光線反射的最佳方法。一般抗反射膜處理可以降低玻璃或塑膠基材對於外界光線的干擾,且可提升玻璃或塑膠基材元件之光穿透率及顏色對比,進而提升使用者對3C產品使用的舒適度。
In recent years, with the sale of Apple's smart phones (i-Phone) and tablet com-puters (i-Pad), touch products have not been converted from high-end to basic func-tions, and various manufacturers have introduced various touches. Products have come to each other, causing 3C product manufacturers to contend. The "touch" func-tion of 3C products, such as Anti-Reflection Film (AFM), insulating film, conductive film, Hard Coating, Anti-Smudge, etc. The control functions are related to the pro-cess parameters of the overall use of the film, and with the increasing demand for touch film functions, we have to pay attention to the overall process of the touch film.
Since the light passes through the surface of the glass or plastic substrate, such as PET, PC, etc., the surface of the medium will have a reflectivity of 4 to 5%, which causes the user to be easily disturbed by external light when using the display, and sees that some are not or changed. Create an image of the outer boundary. At this time, if the anti-reflection film treatment can be performed on the surface of the glass or plastic substrate, it is the best way to solve the light reflection. General an-ti-reflective film treatment can reduce the interference of glass or plastic substrate on external light, and can improve the light transmittance and color contrast of glass or plastic substrate components, thereby improving the user's comfort for 3C products.
In addition to the reflectivity requirements of glass or plastic substrates, an-ti-reflective coatings also require properties such as penetration, hardness, adhesion, and weather resistance. Due to the high difficulty in making optical films on plastic substrates, only a few companies or R&D institutions in foreign countries have this production capability technology. In view of this, this study aims to apply an-ti-reflective coating on the surface of plastic substrate by sol-gel dipping method to find the best anti-reflective film treatment solution.
