[0024] The three-dimensional display film for the LOGO of a notebook model according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0025] As Figure 1-2 shown, the three-dimensional display film for the LOGO of a notebook model according to an embodiment of the present invention includes a backlight module 10, a base module 20, a display module 30, a bottom high-reflection coating layer 40, and a surface low-reflection coating layer 50.

[0026] Among them, the base module 20 is disposed on the backlight module 10, and the base module 20 includes a PET protective film 201, a transparent PC film 202, and an adhesive layer 203.

[0027] Among them, the PET protective film 201 is disposed on the backlight module 10, the transparent PC film 202 is disposed on the PET protective film 201, and the adhesive layer 203 is coated on the transparent PC film 202. The display module 30 is disposed on the base module 20, the bottom high-reflection coating layer 40 is disposed between the display module 30 and the base module 20, and the surface reflection coating layer 50 is disposed on the surface of the display module 30.

[0028] It should be noted that for the backlight module 10, the brightness adjustment range is 100 - 500 cd / m 2, the light source uses an edge LED array. The bottom high-reflection coating layer 40 and the surface low-reflection coating layer 50 form an optical interference structure with a reflectivity difference ≥ 80%. The reflectivity of the bottom high-reflection coating layer 40 ≥ 95%, and the reflectivity of the surface low-reflection coating layer 50 ≤ 15%. The distance between the two coating layers is 5 - 20 μm, forming an optical interference condition with a λ / 4 phase difference. The base module 20 is connected to the display module 30 to form an optical path refraction interface with a 75° inclination angle.

[0029] Furthermore, the bottom high-reflection coating layer 40 usually uses high-reflection materials such as Ag / TiO2 nano-composite film (reflectivity ≥ 95%) or zinc sulfide (ZnS), deposited by magnetron sputtering, with the thickness controlled at 50 - 100 nm, and the distance from the low-reflection layer is 5 - 20 μm to form a λ / 4 phase difference;

[0030] The surface low-reflection coating layer 50 uses low-refractive-index materials such as SiO2 / TaN composite film (reflectivity 12%) or magnesium fluoride (MgF), forming an interference filter with the high-reflection layer to selectively transmit light of a specific wavelength (such as blue light or red light).

[0031] In an embodiment of the present invention, as Figure 2 shown, the display module 30 includes a transparent protective film 301, a light-shielding layer 302, an adhesive layer 303, a coating layer 304, a silica gel protective film 305, and a PE protective film 306.

[0032] Among them, the transparent protective film 301 is disposed on the adhesive layer 203, the light-shielding layer 302 is disposed on the transparent protective film 301, the adhesive layer 303 is disposed on the light-shielding layer 302. The coating layer 304 is disposed on the adhesive layer 303, the silica gel protective film 305 is disposed on the coating layer 304, and the PE protective film 306 is disposed on the silica gel protective film 305.

[0033] It should be noted that the adhesive layer 303 is a UV-curable adhesive with a thickness of 2 - 5 μm and a light transmittance ≥ 92%. The silica gel protective film 305 is embedded with anti-UV nanoparticles with a UV blocking rate ≥ 99%. A sealing rubber ring (not shown) is provided between the display module 30 and the base module 20. The material of the rubber ring is fluororubber with a Shore hardness of 60 - 80A. The PE protective film 306 is used as the outermost protection with a light transmittance of 85 - 95% and a refractive index of 1.45 - 1.6.

[0034] In an embodiment of the present invention, as Figure 2 shown, the light-shielding layer 302 includes a printing layer 3021, an electroplating layer 3022, and a plexiglass layer 3023.

[0035] Among them, the printing layer 3021 is disposed on the transparent protective film 301, the electroplating layer 3022 is disposed on the printing layer 3021, and the plexiglass layer 3023 is disposed on the electroplating layer 3022.

[0036] It should be noted that the printing layer 3021 forms a light-shielding pattern through high-precision printing (1200 - 2400 dpi), and the light transmittance is ≤ 3%.

[0037] The electroplated layer 3022 is a Ni - Cr alloy thin film (with a thickness of 8 - 15 nm), enhancing the light-shielding property and scratch resistance.

[0038] The plexiglass layer 3023 provides mechanical support, with a light transmittance of ≥ 92% and a surface roughness Ra ≤ 0.8 μm.

[0039] In an embodiment of the present invention, as Figure 2 shown, the coating layer 304 includes an electroplated base layer 3041 and a hard base layer 3042.

[0040] Among them, the electroplated base layer 3041 is disposed on the adhesive layer 303, and the hard base layer 3042 is disposed on the electroplated base layer 3041.

[0041] It should be noted that the electroplated base layer 3041 is a Ni - Cr alloy layer (with a light transmittance of 6 - 8%), enhancing the light guiding uniformity.

[0042] The hard base layer 3042 is a silica ceramic layer (with a thickness of 30 - 50 μm), and the flexural strength is ≥ 300 MPa.

[0043] In an embodiment of the present invention, as Figure 1 shown, the base module 20 is provided with a through groove, and the display module 30 is provided with a groove. The groove and the through groove are connected. The groove is a parallel trapezoidal groove, and the side end faces of the groove on the display module 30 are two groups of symmetrically arranged inclined end faces, and the inclination angle of one group of inclined end faces is 75°.

[0044] It should be noted that the through groove on the base module 20 and the groove on the display module 30 form a complementary connection. The inclined end faces are designed with an inclination angle of 75° ± 2°, and cooperate with the silica gel protective film 305 to form an air layer, enhancing the optical path difference.

[0045] In an embodiment of the present invention, as Figure 1 shown, the bottom wall of the groove on the display module 30 coincides with the top wall of the through groove on the base module 20.

[0046] It should be noted that the positions where the groove and the through groove are connected coincide with each other, so that the light is transmitted from below and then transmitted through the backlight module 10 to the base module 20.

[0047] In an embodiment of the present invention, as Figure 2 shown, the light transmittance of the electroplated layer 3022 is 0% - 3%, and the light transmittance of the electroplated base layer 3041 is 6% - 8%.

[0048] It should be noted that the electroplated layer 3022 is a nickel-chromium alloy thin film with a thickness of 8-15 nm, the electroplated base layer 3041 is a silicon dioxide ceramic layer with a thickness of 30-50 μm, and the surface roughness Ra ≤ 0.8 μm.

[0049] Experimental data compared with Chinese Patent (CN202110543215.6):

[0050] Test Items Embodiment of the Present Invention Comparison Scheme Improvement Range Thickness (mm) 0.28 0.65 56.9％ <![CDATA[Brightness (cd / m 2 )]]> 420 280 50.0％ Contrast Ratio (:1) 1200 450 166.7％ Viewing Angle (°) 75°@100cd 30°@200cd 150％ Scratch Resistance (HRA) 62 48 29.2％

[0051] Specifically, the steps for generating and preparing the stereoscopic display film are as follows: An optical interference structure 124 with a λ / 4 phase difference is formed by the bottom high-reflection coating layer 40 and the surface low-reflection coating layer 50. The distance between the two layers is 5-20 μm, and by selectively reflecting specific wavelength light (such as blue light or red light), a two-color alternating display effect is achieved. For example, when the incident light wavelength is 550 nm, the optical path difference Δ of the two coatings is Δ = 2×100 nm×cos75°≈3.1 μm, which matches the visible light wavelength and forms interference fringes.

[0052] The combination of the PET protective film 201 and the transparent PC film, and through the cooperation of the groove and the trapezoidal groove, with a trapezoidal groove inclination angle design of 75°±2°, an optical path refraction interface is formed. Subsequently, the silicone protective film 305 is embedded with anti-UV nano particles, and the UV blocking rate ≥ 99%. At the same time, an air layer is formed to enhance the optical path difference and improve the three-dimensional sense.

[0053] The light-shielding layer 302 uses a Ni-Cr alloy electroplated layer (light transmittance ≤ 3%) to block stray light, while the hard base layer 3042 is SiO2 ceramic with a light transmittance ≥ 6% and has both light guiding and mechanical support functions. Subsequently, the adhesive layer 303 is a UV curable adhesive with a thickness of 2-5 μm and a light transmittance ≥ 92% to ensure close fitting between the modules.

[0054] In summary, the stereoscopic display film for the LOGO of the notebook model in the embodiment of the present invention is applicable to the notebook computer body with a thickness ≤ 1.5 mm, breaking through the thickness limitation of the traditional display module, without the need for a surface light source to introduce light, using the inclined plane of the boss and groove to reflect the light source, and the continuous viewing angle reaches 75°@100 cd / m 2 , so that the light source entering the product generates a certain angle and is continuously reflected between the upper and lower surfaces of the product to form an infinite mirror effect.

[0055] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and deformations to the above embodiments within the scope of the present invention.
