In some embodiments, the display device includes an anti-reflective pattern or columnar spacer disposed between the light-emitting diode and the diaphragm layer and comprising a blue colorant. Blue light reflected from the anti-reflective pattern or columnar spacer is almost imperceptible. Image quality can be improved by preventing rainbow spots (or blotches) caused by reflections of external light. Since blue light emitted from the light-emitting diode can pass through the anti-reflective pattern and / or columnar spacer, the light intensity emitted from the light-emitting diode can be increased.

This application relates to a glass assembly and a vehicle. A first shielding layer is disposed on the glass body and covers the boundary line. The first shielding layer includes two opposing contour edges, which are respectively disposed in the coating area and the viewing area. Thus, the coating layer can reduce the light intensity and temperature of the coating area, thereby effectively preventing burns to drivers and passengers. Furthermore, since the coating layer does not cover the viewing area, the viewing area is clearer, making it easier for drivers and passengers to observe. Additionally, by covering the boundary line and having its two contour edges respectively disposed in the coating area and the viewing area, the shielding properties of the first shielding layer can indirectly eliminate or reduce product appearance defects at the boundary line, preventing defects such as refraction, rainbow stripes, and bright lines, thereby improving the product's value and providing drivers and passengers with a comfortable field of vision, thus improving driving safety.

This invention relates to an improved Fresnel prism based on the principle of refraction-total internal reflection-refraction. To address the high cost of existing circular rainbow generation devices and supplement deficiencies in color order, it provides a reusable device and method for enhancing ring rainbows. The invention utilizes a refraction-total internal reflection Fresnel prism to achieve ring rainbows, comprising a Fresnel prism and a projection screen. The rotation axis of the Fresnel prism is perpendicular to the projection screen. One side of the Fresnel prism is flat, and the other side is toothed.

Incident light, parallel to the rotation axis of the Fresnel prism, enters and penetrates the prism from the connected bases, and is then projected perpendicularly onto the projection screen. This invention is primarily applied to the design and manufacture of optical equipment with high optical performance.

This invention discloses an AR near-eye display method that reduces rainbow light, belonging to the field of augmented reality near-eye display technology. It solves the problem of significant rainbow light and visual obstruction caused by existing diffraction waveguides. In this method, the RGB beam emitted from the display optical engine is coupled into a diffraction waveguide matrix distributed in the area above the lens. The emission angle of each diffraction waveguide is controlled according to a pre-established position-wavelength-emission angle mapping model θ(x,y,λ)=θ0+γ·(x+y)·(λ-λ0), so that the emission angle deviation of different wavelengths is dispersed in two-dimensional space. The projected area of ​​the diffraction waveguide matrix occupies ≤2% of the lens. This AR near-eye display method that reduces rainbow light can significantly suppress rainbow light and is mainly used in head-mounted AR glasses to achieve a thin, lightweight, low-artifact, high-quality display.

The application discloses a light scattering suspended drop shape parameter measurement system and method, and belongs to the technical field of fluid characteristic research. The method comprises the following steps: using a monochromatic coherent laser beam, expanding the laser beam into an incident light with a beam width of 3-5 times of the diameter of the suspended drop to uniformly irradiate the suspended drop; adopting a combined bilinear CCD detector to respectively collect first-order rainbow signals and second-order rainbow signals generated by the suspended drop scattering; performing fast Fourier transform filtering on the collected signals, reconstructing a scattering angle distribution diagram after filtering out high-frequency components; extracting the positions and intensities of multiple groups of scattering peak values in the scattering angle distribution diagram, calculating the radius of the suspended drop through the position interval of the multiple groups of peak values, and calculating the vertical direction curvature radius of the suspended drop through the ratio of the multiple groups of peak values of the first-order rainbow and the second-order rainbow. The method breaks through the limitation that the existing light scattering measurement method can only be applied to spherical liquid drops / circular liquid columns, and successfully expands the light scattering measurement technology to the shape parameter measurement of non-spherical liquid drops.
