Detailed Description
In order to promote information, the embodiment of the application provides a preparation method of an anti-interference scratch-proof adhesive film, the adhesive film and a screen. In order to better understand the technical solution provided by the embodiments of the present application, the following brief description is made for the important concept of the solution:
referring to fig. 1a, in the prism layer of the conventional DOP adhesive film, a large prism peak Pitch equal-height structure (Pitch is between 60 and 70um, there are one or more pitches with different sizes, the total Pitch value falls in this interval, and a sticky adhesive is used to adhere the peak of the prism layer and the back of the diffusion layer together, referring to fig. 1b, the actual condition is that the thickness of the adhesive is large, a part of the peak of the prism layer is submerged into the adhesive layer, and the more submerged part is in a unit area, the more scattered light is emitted, so that the lower the brightness of the finished product is, in other words, referring to fig. 1c, the larger the Pitch is in the same unit area, the smaller the density of the prism structure peak is, the smaller the area where the adhesive is adhered is, and the higher the brightness of the finished product is.
Because the pitch of the prism structure is between 60 um-80 um, and exceeds the conventional distance between 60 um-70 um, the prism can easily form interference fringes with the pixel units of the high-definition screen, and the larger the pitch, the higher the interference risk.
In addition, the high-definition screen polaroid is high in transparency, the surface of the polaroid is not scratch-resistant, and the polaroid is easily scratched by a diffusion layer on the traditional DOP.
The embodiment of the application provides a preparation method of an anti-interference scratch-resistant laminating film, a laminating film and a screen, and aims to solve the problem that the traditional DOP laminating film is dry in display and relates to an easily scratched polarizer.

The prism layer is of a triangular structure with the peak pitch (pitch interval) of the prisms of 25-50 microns (preferably 45-50 microns) and the apex angle of 88-90 degrees. The prism peaks are machined to a specific structure with staggered heights. The vibration rules of two adjacent prism structures are consistent, so that high points and low points in the cross sections of all the prisms are on the same horizontal line.
The prism peak pitch of the prism layer becomes smaller, resulting in a decrease in brightness of the finished product, namely: the small structure will lead the light not to be collected to the middle area, and the contact surface between the prism peak and the joint glue in unit area is increased, which will lead the brightness of the product to be reduced, therefore,
s23, arranging the prism layer of the diffusion film to be a jitter structure, wherein the jitter amplitude is larger than 6 microns;

Equal height 50pitch 0.2mm2
Jitter 50pitch 0.1mm2Jitter structure
Equal height 40pitch 0.25mm2
