摘要： A display panel includes an array substrate, a composite functional layer, a first adhesive layer and a cover plate. The composite functional layer is located on a side of the light-emitting layer away from the base substrate. A through hole penetrating through the composite functional layer and the array substrate is formed on the array substrate and the composite functional layer. The array substrate includes a non-display area surrounding the through hole. The composite functional layer includes a first shading layer, and the orthographic projection of the first shading layer on the array substrate is located in the non-display area of the array substrate. The first adhesive layer is located on a side of the composite functional layer away from the base substrate. The cover plate is located on a side of the first adhesive layer away from the base substrate.

摘要： Systems and methods that include: providing input information in an electronic format; converting at least a part of the electronic input information into an optical input vector; optically transforming the optical input vector into an optical output vector based on an optical matrix multiplication; converting the optical output vector into an electronic format; and electronically applying a non-linear transformation to the electronically converted optical output vector to provide output information in an electronic format.
In some examples, a set of multiple input values are encoded on respective optical signals carried by optical waveguides. For each of at least two subsets of one or more optical signals, a corresponding set of one or more copying modules splits the subset of one or more optical signals into two or more copies of the optical signals. For each of at least two copies of a first subset of one or more optical signals, a corresponding multiplication module multiplies the one or more optical signals of the first subset by one or more matrix element values using optical amplitude modulation. For results of two or more of the multiplication modules, a summation module produces an electrical signal that represents a sum of the results of the two or more of the multiplication modules.

摘要： The present application provides a backlight module and a display device, including a light source component, a quantum dot component, and a wavelength-band-light-reflecting component being arranged in a stack. The wavelength-band-light-reflecting component reflects light emitted by the quantum dot component in a specific band range, so as to reduce full width at half maximum of the light. The present application reduces the full width at half maximum of monochromatic light by arranging the wavelength-band-light-reflecting component reflecting light in the specific band range, thereby increasing gamut of a display module.

摘要： The invention refers to a diffusion plate and a backlight module having the diffusion plate. The diffusion plate comprises a plate-body and a plurality of pyramid-like structures arranged on a surface of the plate-body. Each pyramid-like structure has a bottom surface, a first convex portion and a second convex portion. The first convex portion and the second convex portion have different vertex angles, and therefore the pyramid-like structure can also be called as “pyramid-like structure with multiple vertex angles”. The pyramid-like structures with multiple vertex angles can increase the light splitting points, which can improve the light splitting effect of the diffusion plate. The light source of a single light-emitting diode can be divided into eight point-light sources (light splitting points) or more, which is double the number of light splitting points compared with the traditional pyramid structure with single vertex, and thus can greatly improve the light diffusion effect.

摘要： Provided is a meta-optical device exhibiting a target phase delay profile with respect to incident light of a predetermined wavelength band, the meta-optical device including: a first layer including a plurality of first nanostructures and a first surrounding material surrounding the plurality of first nanostructures, and having a first phase delay profile of a first tendency that is substantially equal to a tendency of the target phase delay profile; a second layer including a plurality of second nanostructures and a second surrounding material surrounding the plurality of second nanostructures, and having a second phase delay profile of a second tendency that is substantially opposite to the tendency of the target phase delay profile; and a third layer including a plurality of third nanostructures and a third surrounding material surrounding the plurality of third nanostructures, wherein the third layer is different from the second layer in terms of at least one of a material and an arrangement rule. The meta-optical device is capable of minimizing a primary dispersion and higher-order dispersions and thus may exhibit constant diffraction efficiency with respect to light of a wide wavelength band.

摘要： A system and method are provided for forming one-way light transmissive layers implementing optical light scattering techniques in those layers, and to objects, object portions, lenses, filters, screens and the like that are formed of, or that otherwise incorporate, such one-way light transmissive layers. Processes are provided by which to form, or otherwise incorporate, one or more one-way light transmissive, or substantially transparent, object portions or layers in solid or hollow objects Individual one-way light transmissive layers are formed of substantially-transparent sub-micrometer spheres, including micro-particles and/or nano-particles, with nano-voids incorporated between them. Refractive indices of the sub-micrometer particles are tunable in order that the finished layers provide an opaque appearance when viewed from a light incident side that is rendered according to an individual user's desires, but that are substantially-transparent to light passing through the finished layers to areas or sensors behind those finished layers.
