Although the output value of anti-reflective optical film for LCD display pvd coating machine does not account for a high proportion of the overall TFT LCD, it plays a role like a "makeup artist" for LCD displays. If an anti-reflection optical film is added above the LCD panel, it can not only increase the visibility of the LCD display, improve the image quality performance, but also provide protection against scratches and stains.

        Anti-reflection optical films used in LCD displays are roughly divided into two categories, one is an anti-reflection (AR) optical film, and the other is a low-reflection (Low-Reflection; LR) optical film.
       The anti-reflection optical film of the vacuum coating machine is placed in the uppermost position of the LCD panel module structure, that is, above the polarizer. Layer" and "TAC layer" three categories, if the anti-reflection optics add other functions, such as anti-glare (Anti-Glare; AG) effect, it can be further developed into AGAR and AGLR type optical films.
       Why does pvd coating machine anti-reflection optical film play an important role in LCD displays? The reason is that it adds anti-reflection function, so it can improve the visibility of the LCD display and also improve the contrast value; in addition, because the anti-reflection optical film contains a hard coat layer, it can prevent external foreign objects or artificial scratches; moreover, Since the anti-reflection optical film is located at the top of the LCD panel, it is necessary to add anti-fouling function.
       Although not all LCD displays must use the anti-reflection optical film of pvd coating machine, in 2007 as an example, it is estimated to account for only about 1/4 of the total LCD display usage. For LCD displays used in products, or large-size LCD TVs, in order to avoid product damage, increase durability, and display better image quality, anti-reflection optical films for vacuum coating machines still play an important role in LCD displays.
