DISPLAY DEVICE FOR TRANSPARENT GLASS Russian patent published in 2018 - IPC G02B27/01 G02B1/115 

FIELD: electricity.

SUBSTANCE: invention relates to the field of image display and relates to a device for displaying a real image on glass, which is equipped with a cabin or a facade. Device includes a source of laser radiation source and glass, a portion of which comprises a phosphor. On the side facing the radiation source, the glass has an antireflection coating for incident monochromatic laser radiation illuminating a portion of the glass. Antireflection coating is formed by a set of two layers, including, starting from a substrate having a glass function, a first layer made of material based on zinc oxide, tin oxide, silicon nitride, zinc oxide and tin and silicon oxide and zirconium, and a second layer made of a silica-based material. Geometric thicknesses of the layers are equal Ep₁=26+0.07(θ)-0.007(θ)² for the first layer and Ep₂=83-0.1(θ)+0.01(θ)² for the second layer, where θ is the average angle of orientation of the incident monochromatic laser radiation relative to the normal to the glass in the illuminated portion.

EFFECT: technical result is improved safety of the device.
