Detailed Description
In order to promote information, the embodiment of the application provides a preparation method of an interference-resistant and stain-resistant laminating film, a laminating film and a screen. In order to better understand the technical solution provided by the embodiments of the present application, the important concepts of the solution are basically briefly described below:
referring to fig. 1a, in the prism structure of the conventional MOP laminated film structure layer, a large prism peak Pitch equal-height structure (Pitch is between 60 and 70um, and there are one or more pitches with different sizes), the total Pitch value falls in the interval, and the peak of the prism layer and the back of the diffusion layer are adhered together by using adhesive, referring to fig. 1b, the actual situation is that the adhesive has a thickness, a part of the peak of the prism layer is immersed into the adhesive layer, the more the immersed part is, the lower the brightness of the finished product is caused, in other words, the smaller the density of the prism structure peak is, the smaller the area to which the adhesive is adhered is, and the higher the brightness of the finished product is caused, referring to fig. 1c, in the same unit area.
Because the pitch of the prism structure is between 60um and 80um, and exceeds the conventional distance between 60um and 70um, the prism can easily form interference fringes with pixel units of a high-definition screen, and the larger the pitch is, the higher the interference risk is.
In addition, the MOP micro structure has special (equal-height hemispherical structure) surface not smooth, and white printing dirt transfer printing is caused after the MOP micro structure contacts with the latex glove in the conveying process.
The embodiment of the application provides a preparation method of an interference-resistant and stain-resistant laminating film, a laminating film and a screen, which are used for solving the problems that the conventional MOP laminating film is poor in interference and surface stain resistance.
The method for preparing the anti-interference and anti-fouling laminating film according to the embodiment of the application is further described below with reference to the accompanying drawings, as shown in fig. 2a, and the method comprises the following steps: the conformable film includes: a micro-transmissive array film and a prismatic layer, wherein:
s21, bonding the prism layer below the micro-permeable array film;
MOP laminated film, microlens ON Prism, i.e. composite film of micro-transparent array film and prism laminated together
The MOP laminating film structure is respectively a structural layer (prism layer) and a Microlens layer from bottom to top, and the structural surface of the structural layer (prism layer) and the back surface of the Microlens layer are adhered by compound adhesive
The front surface of Microlens is a hemispherical structure arranged in a certain order.
S22, setting the peak pitch of the prisms of the prism layer to be 25-50 microns, and configuring the peak tangent plane angle of the prisms to be a triangle structure with an angle of 88-90 degrees;
referring to fig. 2b, the prism peak pitch of the prism layer is set to 25-50 micrometers specifically: the prism peak pitch is set to 45-50 microns.
The prism layer has triangular structure with apex angle of 88-90 deg. and peak pitch (pitch) of 25-50 microns (45-50 um is preferable). The peaks of the prisms are processed into special structures with staggered height. 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 ensured to be on the same horizontal line.
The prism peak pitch of the prism layer becomes smaller, resulting in a reduction in brightness of the finished product, namely: the small structure can lead light to not collect towards the middle area, and the contact surface between the prism peak and the laminating adhesive in unit area is increased, thus the brightness of the product is reduced,
s23, setting a prism layer attached to the micro-transparent array film to be a shaking structure, wherein the shaking amplitude is larger than 6 microns;
the jitter amplitude refers to: jitter peak and jitter valley height fall.
In fig. 2b to fig. 2c, the dithering period of the dithering structure is that the heights of the transversely extending peaks of the prisms are consistent, and the widths are configured to be 200-600 um;
the width of the extending wave trough is consistent and is configured to be 0.5-0.75 times of the width of the transversely extending wave crest
The specific numerical values can be determined according to actual production requirements, and experimental data refer to the following table data:
| structure of the | In the unit surface joint of the finished product, the prism peak and the bonding adhesive joint area are/mm < 2 > |
| Equal-height 70pitch | 0.143mm 2 |
| Equal-height 60pitch | 0.167mm 2 |
| Equal height 50pitch | 0.2mm 2 |
| Dithering 50pitch | 0.1mm 2 Dithering structure |
| Equal-height 40pitch | 0.25mm 2 |
| Dithering 40pitch | 0.125mm 2 Dithering structure |
The problem of interference is solved by reducing the peak pitch of the prisms, the contact area of the prism peaks in unit area and the adhesive can be reduced by using dithering, and the brightness of the product is ensured.
S24, laminating the prism layer and the lower part of the micro-permeable array film by adopting PET laminating adhesive paint;
due to the shaking design, the prism peak and the bonding adhesive area are reduced in a unit area, the bonding force between the upper layer and the lower layer is poor due to the small contact area, and then the bonding force is improved on the basis of the same contact surface through the bonding adhesive.
And S25, coating the front surface of the micro-permeable array film with a stain-resistant coating.
