Its core technology utilizes precision optical films and layered perspective processing to construct a dynamic three-dimensional light field within the glass substrate, combining high-precision sensors and naked-eye 3D algorithms to achieve spatial imaging that blends the virtual and real worlds.

[0003] The 3D holographic cabin optoelectronic glass screens currently in use employ traditional conductive glass or single-function layer structures, which are insufficient in terms of brightness and energy efficiency. Utility Model Content

[0006] A 3D holographic capsule optoelectronic glass screen includes a composite substrate layer, a dynamic dimming layer, a holographic grating layer, a piezoelectric microstructure touch layer, a photoelectric conversion layer, and an anti-interference isolation layer. The dynamic dimming layer is bonded to the front end of the composite substrate layer, the holographic grating layer is bonded to the front end of the dynamic dimming layer, the piezoelectric microstructure touch layer is bonded to the front end of the holographic grating layer, the photoelectric conversion layer is bonded to the front end of the piezoelectric microstructure touch layer, and the anti-interference isolation layer is bonded to the front end of the photoelectric conversion layer.

[0007] Based on the above technical solution, the composite substrate layer includes alumina-strengthened glass, a polycarbonate layer, and a silica hydrophobic film. The alumina-strengthened glass has a polycarbonate layer distributed at its front end, and the silica hydrophobic film is deposited on the surface of the polycarbonate layer. This structure maintains 85% light transmittance while increasing the impact resistance to 3 times that of ordinary tempered glass, and the surface hardness reaches Mohs 6.

[0008] Based on the above technical solution, the dynamic dimming layer is a dual-mode control layer composed of an electrochromic tungsten-doped indium oxide thin film and a polymer-dispersed liquid crystal. Two operating modes can be achieved through voltage control:

[0009] Transmission mode 0-5V: Liquid crystal molecules are arranged in an orderly manner, and the light transmittance is >80%.

[0010] Scattering mode 5-12V: Disordered distribution of liquid crystals leads to light diffusion effect.

[0011] Based on the above technical solution, the holographic grating layer is fabricated using two-photon polymerization technology to create a subwavelength periodic grating with a line width of 80-120 nm and a depth ratio of 1:3. A nanolayer with a continuously varying refractive index from 1.8 to 1.45 is formed by alternating deposition of titanium dioxide and silicon dioxide, achieving a naked-eye 3D effect within a 120° viewing angle.

[0012] Based on the above technical solution, the piezoelectric microstructure touch layer adopts a combination of lead zirconate titanate micropillar array and graphene electrodes, and achieves multi-point touch positioning accuracy of <0.5mm and response time of <8ms through stress-voltage conversion. The micropillars have a diameter of 20μm, a spacing of 50μm, and a coverage of 90%.

[0013] Based on the above technical solution, the photoelectric conversion layer 5 integrates a perovskite quantum dot thin film CsPbBr3 and an organic photovoltaic material PM6:Y6 to form a dual-band energy harvesting system:

[0014] Visible light wavelength 400-700nm conversion efficiency >18%

[0015] Near-infrared band 800-1100nm conversion efficiency >12%

[0016] The output power is directly supplied to the dimming layer and the touch layer, achieving energy self-sufficiency.

[0017] Based on the above technical solution, the anti-interference isolation layer is formed by blending hexagonal boron nitride and polyimide, with a dielectric constant controlled at 2.1-2.3@1MHz and a breakdown field strength >300kV / mm. This layer effectively isolates electromagnetic interference between functional layers and also possesses excellent thermal conductivity >25W / m・K.

[0018] Compared with the prior art, the present invention has the following advantages: The present invention breaks through the technical bottlenecks of existing holographic screens in terms of energy efficiency, viewing angle range and environmental adaptability through the innovative combination of 6 functional layers, and has technical features that are significantly different from existing patents.
