The laser-engraved matrix point 22 arranged on the arc-shaped transparent acrylic plate 21 adopts a specific row spacing (1.5mm) of left and right points and an interlaced upper and lower point column spacing (1.5mm) point array overall layout controlled precisely, so that the curved surface holographic projection glass 2 realizes an optimized balance between light transmittance and scattering effect. When the light projected by the projector irradiates on the curved surface holographic projection glass 2 in the night or dark environment, the engraved part occurs diffuse reflection phenomenon due to the frosted rough surface, the light is reflected irregularly in all directions, and the matrix point brightness emits light higher than other parts, so that the holographic projection of coarse pixels is realized by the imaging attached; when the laser light passes through the rough surface of the frosted structure, diffuse reflection phenomenon occurs, the light is reflected irregularly in all directions, and the viewing distance of clear imaging is 1000 times the pixel point spacing according to the specific row spacing (1.5mm) controlled precisely, so that clear images can be formed at a viewing distance of 1.5m or more; and in the daytime, since the overall light environment is relatively bright, the ambient brightness is consistent with the matrix point brightness, the daylight passes through the frosted surface matrix point, and there is no obvious difference between the ordinary glass in vision, and the whole shows good light transmittance.

The linear array distribution of the laser-engraved matrix point 22 arranged on the arc-shaped transparent acrylic plate 21 realizes that the glass still has a high transparency of 92.55% even in the daytime environment with strong brightness. The specific row spacing (1.5mm) of left and right points and the interlaced upper and lower point column spacing (1.5mm) point array overall layout controlled precisely make the curved surface holographic projection glass 2 have excellent imaging effect.
