AI Technical Summary
In the existing transparent display technology, the observation angle, transparency and signal brightness of the projected HUD still need to be improved, and the nanoparticle preparation process is complex and time-consuming, making it difficult to realize a simple, fast and mass-produced color transparent display screen.
The transparent display screen process based on plasmon particles is adopted, and the metal particle layers are sequentially plated on the transparent substrate, and the argon ion sputtering coating meter and electron beam thermal evaporation coating meter are used for coating. The silver-alumina, silver-titanium dioxide and gold-titanium dioxide core-shell structures are formed by combining annealing treatment and atomic layer deposition methods. Finally, the silica dielectric layer is plated on the metal particles to adjust the resonance wavelength.
It realizes a color transparent display with simple process, short cycle and mass production, improves display performance, reduces preparation costs, and has uniform distribution of metal particles and controllable resonance wavelength.
