Background technology
The display picture of liquid crystal display will produce mirror when by the light of ambient enviroment such as sunlight or extraneous light-illuminating
Face is reflected and generates the phenomenon that mirroring, the picture that display screen should be shown will with the overlappings such as the light and landscape mirrored by the external world,
So that display image clearly declines, the appreciation effect for showing picture is influenced.The better method for solving this phenomenon is to display screen
It carries out antireflection process or uses antireflection film on the outside of screen.
Anti- (subtracting) reflectance coating is also known as anti-reflection film (AR films), and main function is to reduce electronics screen, video screen etc. in environment
What is generated under light source is reflective, increases light transmittance, screen-picture is made to be more clear.Liquid crystal display with antireflection film is suitable for
The occasion of aircraft cabin, terminating mobile phone, colour screen handset, laptop and large-scale monitor grade height performance requirement.
Antireflection film mainly reduces the reflection of light in terms of two.On the one hand, reflectivity of the light on interface and interface two
The refractive index of side medium is related, and refringence is smaller, then reflectivity is also smaller；On the other hand, made by adjusting the thickness of film layer
Reflected light on two interfaces of film layer forms certain phase difference, to interfere cancellation, can also reduce the reflection of light.Due to certain
The antireflection film layer of one thickness can only have preferable anti-reflection effect to the light of wavelength in a certain range, therefore, general anti-
Reflectance coating is required for the film layer for the different refractivity for having more to obtain lower light reflectivity.
《The research and application of film surface hardening coat》(" research and application of film surface hardening coat ", Du Yanfei,
Information-recording material, the 6th phase volume 13 in 2012) structure of antireflection film is disclosed, there is touch layer, the low folding stacked gradually
