Film coating machine plating process for mobile phone screen film

Mobile phone color LCD screen on the reflection protective film, reduce eye by outside glare stimulation effect, enhance viewing comfort, and to protect the eyes. The substrate is commonly used mobile phone PC or acrylic material. These two kinds of substrate, as the protection screen of the color LCD display, have the disadvantage of high reflectivity. Because at least 4.2% of the reflectivity of the screen surface is not coated, the intensity of the reflected light will decrease the contrast of the display image. So, if the surface of the protective shield is less than 0.5%, it will increase the clarity of the display screen.

Ti02 film with high refractive index and low refractive index of Si02 film are deposited on the surface of the protective screen by the coating device, and the protective screen has the effect of low reflection and enhancement. Because PC or acrylic base material of organic material, so the deposition temperature should be within the range of 30-35 DEG C.

Coating technology

(1) substrate -PMMA, PC.

(2) the film is the one or two layer of the ten layer of anti reflective film.

(3) coating. Reactive deposition of a continuous magnetron sputtering coating machine.

Power supply: Si target if power supply, Ti target with DC ten pulse power supply.

Vacuum degree: Ar, 02, vacuum degree is 5X10-1Pa.

Temperature: 25 ~ 35.

Finally, a waterproof film deposition IAF3.
