Although the output value of the anti-reflective optical film of the LCD display PVD coating machine is not high in the overall TFT LCD, it plays a role like a "makeup artist" for the LCD display. If an anti-reflective optical film is added to the top of the LCD panel, it can not only increase the visibility of the LCD display, improve the image quality, but also have protective effects such as scratch resistance and anti-fouling.
Anti-reflection optical films used in LCD displays can be roughly divided into two categories, one is anti-reflection (AR) optical film, and the other is low-reflection (LR) optical film.
The anti-reflective optical film of the
pvd coating machine is placed in the uppermost position of the LCD panel module structure, which is above the polarizer. If you look closely at the structure of the anti-reflective optical film, it can be roughly divided into "anti-reflective layer" and "hard film" There are three types of "layer" and "TAC layer". If anti-reflective optics is added with other functions, such as anti-glare (AG), it can be further developed into AGAR and AGLR type optical films.
Why does the anti-reflective optical film of the vacuum coater play an important role in the LCD display? The reason is that its anti-reflection function is added, 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 coating layer, it can prevent foreign objects or artificial scratches; moreover, Since the anti-reflective optical film is located on the top of the LCD panel, anti-fouling function is required.
