preparation example Construction

[0098] One embodiment of the present invention provides a method for preparing an antireflection film, comprising the following steps:

[0099] A hard coating, a high refractive index coating, a low refractive index coating, and an anti-fingerprint coating are sequentially formed on one side of the substrate.

[0100]In some examples, in the method for preparing the anti-reflection film, the step of forming the hard coating includes: coating the raw materials for the hard coating on the substrate and curing them.

[0101] In some examples, in the preparation method of the anti-reflection film, the step of forming the high-refractive-index coating includes: coating the raw material for preparing the high-refractive-index coating on the hardened coating and curing it.

[0102] In some examples, in the method for preparing the anti-reflection film, the step of forming the low-refractive-index coating includes: coating the raw material for the low-refractive-index coating on the h...

Embodiment 1

[0109] By weight percentage, the components of each layer of the antireflection film are as follows:

[0110] Substrate: PET (purchased from Toray, Japan, U483, thickness 50 μm);

[0111] Thickness of hardened coating (4μm, surface dyne value 32): 30% polyurethane acrylic resin (functionality 9, glass transition temperature 35°C), dipentaerythritol hexaacrylate 10% (functionality 6), carboxyl Treated silica 10% (particle size 5nm), initiator 1-hydroxycyclohexyl phenyl ketone 3% and ethyl acetate 47%;

[0112] High refractive index coating (refractive index 1.6, thickness 80nm): polyurethane acrylic resin 20% (functionality 3), 2-phenoxyethyl methacrylate 20% (functionality 3), amino-treated Zirconia 40% (particle size 5nm), initiator 1-hydroxycyclohexyl phenyl ketone 3% and tetrahydrofuran 17%;

[0113] Low refractive index coating (refractive index 1.35, thickness 80nm): polyurethane acrylic resin 20% (functionality 9, glass transition temperature 35°C), dipentaerythritol h...

Embodiment 2

[0121] Basically the same as Example 1, the difference is that the components in the hardened coating are different, as follows:

[0122] Hard coating (thickness 4μm, surface dyne value 50): 30% polyurethane acrylic resin (functionality 9, glass transition temperature 35°C), dipentaerythritol hexaacrylate 10% (functionality 6), carboxyl Treated silica 40% (particle size 5 nm), initiator 1-hydroxycyclohexyl phenyl ketone 3% and acetone 17%.

Abstract

The invention relates to an anti-reflection film and a display device. The anti-reflection film comprises a base material, and a hardened coating, a high-refractive-index coating, a low-refractive-index coating and an anti-fingerprint coating which are sequentially laminated on one side of the base material, the hardened coating is prepared from the following raw materials: first polyurethane acrylic resin, dipentaerythritol hexaacrylate, first polar functional group modified inorganic particles, a first initiator and a first organic solvent. The coating components of the anti-reflection film and the coatings have a synergistic effect, so that the anti-reflection film has low reflectivity and high wear resistance at the same time.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an anti-reflection film and a display device. Background technique [0002] At present, display devices are widely used in fields such as mobile phones, computers, large-screen touch controls, and vehicle displays. However, when the display device is exposed to external light such as lighting or natural light, the external light is reflected on the surface of the display device, and the reflected image caused by it is mixed with the displayed image, making it impossible for the naked eye to see the image formed inside the display. It can also cause eyestrain or headaches. [0003] Attaching the anti-reflection film to the surface of the display screen of the display device can reduce the reflection of external light on the surface of the display device, and solve the problem that the internal image of the display device cannot be seen clearly by the naked eye. However, traditi...
