Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.

FIG. 1 is a schematic view of the product structure of the present invention;

fig. 2 is the schematic view of the structure of the anti-reflection layer of the present invention.

The specific implementation mode is as follows:

the technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the case where the TFT glass panel has not been changeable, the realization of the integral black can be realized only by changing the color of the panel. The implementation of the "integral black" panel is as follows:

and (3) screen printing mode: after the cover plate is subjected to CNC, strengthening and silk-screen/evaporation black frame printing, a layer of IR printing ink semi-permeable printing is carried out on a window area or a key part of the glass cover plate, and the integral black effect is realized by adjusting the color and transmittance of the printing ink.

The film coating mode is as follows: different from a silk screen printing mode, the technology for realizing 'integral black' independently developed by Woge photoelectricity directly plates an inorganic film on a glass cover plate through magnetron sputtering and an optical principle, and adjusts reflection, transmission and chromatic aberration of a film layer window area, so that the colors of a touch display screen window and a silk screen frame are consistent. The transmittance can reach 80 percent, and the reflectivity is less than 2 percent.

Semi-transparent materials are used: the integrated black effect is realized by directly using a semi-transparent material, and the material can be plastic or glass. The plastic material is processed into integral black, toner is usually added into resin material, and the integral black effect is realized by blending the addition amount of the toner in the material; the glass can be added with color during production, and can also be dyed. The processing mode of directly using the semi-transparent material can realize fine 'integrative black' visual effect, and apron surface permeability is unanimous.

The screen that can't satisfy through the integrative black of silk screen printing mode realization apron has low reflection effect among the above-mentioned three scheme, and is not good to improving screen image quality effect. And the integrated black process debugging window is narrow only by a film coating mode. The semi-transparent material is used in the same way as the screen printing method, which has a poor effect on improving the screen quality. The middle coating mode is similar to the mode of directly using a semi-transparent material, a hardened layer with nano black pigment is coated on the surface of the base material, so that the base material is semi-transparent, the reflectivity of the surface of the screen is reduced by combining with the coating, the screen effect is better, and the result of the two modes also changes the disadvantage of narrow window only passing through the coating process.

The utility model provides an integrative black display effect's diaphragm, like figure 1, include from type membrane 1, gluing layer 2, substrate 3 (not being limited to PET, TAC, SRF etc. and PET, semi-transparent type anti-dazzle layer 4(AG), antireflection layer 5(AR) and anti-fingerprint layer 6(AF) are selected to the present case.

The semi-transparent anti-glare layer has a transmittance of 50-80%, the outermost layer of the anti-reflection layer is a low-refractive-index film layer, a high-refractive-index film layer is arranged below the outermost layer, and the high-refractive-index layer and the low-refractive-index layer are sequentially alternated.

As shown in fig. 2, the low refractive index film layer and the high refractive index film layer of the antireflection layer are provided with 5 layers in total.

The outermost layer of antireflection layer is low refracting index rete, and adjacent outermost below is high refracting index rete, and high refracting index layer and low refracting index layer alternate in proper order.
