This invention belongs to the field of photoresist technology, specifically relating to a compound containing a multifunctional polysiloxane structure and its applications. The structural formula is selected from general formula I or general formula II. Based on an organosiloxane polymer, this invention introduces multifunctional reactive functional groups into the polymer structure through transesterification and free radical addition reactions. The hydrophilic / hydrophobic properties, temperature resistance, and chemical resistance can be improved by adjusting the types of monomers introduced. This compound is used to prepare a photoresist composition with a solvent, a monomer with ethylene unsaturated bonds, a photosensitizer, and other additives. This photoresist exhibits advantages such as low dielectric constant, good adhesion, high residual film rate, good UV transmittance, good patterning, and good chemical resistance.

This invention discloses an automotive lens with a composite electrochromic glass layer. It includes a lens body made of molded optical glass; the front side of the lens body has an aspherical convex light-emitting surface, and the rear side of the lens body is a flat light-incoming surface. Electrochromic glass is compositely connected to the light-incoming surface, and the edge of the lens body has outwardly protruding snap-fit ​​mounting edges. This invention, by compositely connecting electrochromic glass to the flat light-incoming surface of the rear side of the lens glass, changes the color of the electrochromic glass, altering the visual effect of the automotive lens and giving it a more premium feel. By changing the transparent electrochromic glass to a darker color, the light transmittance of the automotive lens can be reduced, allowing the lens to adjust its light transmittance according to different environmental and weather conditions. This invention not only improves the visual effect but also has the advantages of adjustable light transmittance, low manufacturing cost, and good durability.

The invention relates to the technical field of ink preparation, in particular to a high-blackness ink formula for LED display packaging and an organic silicon modified resin gradient dispersion process. The high-blackness ink formula is prepared from, by mass, 8-20 parts of high-blackness composite pigment, 30-50 parts of organic silicon modified resin, 2-8 parts of polymeric dispersant, 1-5 parts of functional additive and 15-35 parts of high-purity solvent. The organic silicon modified resin provides excellent high and low temperature resistance and yellowing resistance, the unique molecular structure of the organic silicon modified resin is more beneficial to wetting and coating of pigment particles, the three-stage gradient dispersion process is matched with online monitoring, and through stepped increase of the rotating speed and the temperature and ultrasonic assistance, the high-temperature-resistant and anti-yellowing performance of the pigment is improved. Progressive dispersion of the pigment from preliminary wetting to deep coating is realized, and nanoscale uniform distribution and long-term stability of the pigment in resin are ensured. The finally prepared ink has the comprehensive advantages of high blackness, low light transmittance, strong adhesive force, wide process window and the like, and perfectly meets the packaging requirements of high-end LED display.

This utility model discloses a screen structure and a high-gain white screen, belonging to the field of projection display technology. The screen structure includes two substrate layers, with a barrier layer bonded between the two substrate layers via an adhesive layer. The substrate layers, adhesive layer, and barrier layer have different refractive indices. The high-gain white screen includes a protective layer, a diffusion layer, and the aforementioned screen structure, arranged sequentially from the incident surface to the back surface. By utilizing the difference in refractive indices between the substrate layer, adhesive layer, and barrier layer, an optical effect similar to mother-of-pearl is created, reducing light penetration and enhancing light reflection and scattering. This improves detail rendering, reduces the loss of dark areas, enhances resistance to external light interference, reduces contrast, reduces color saturation distortion, reduces light loss during propagation, improves overall brightness uniformity, ensures full presentation of high-resolution signal details, and is compatible with more projection devices.

This application discloses an AD calcium beverage packaging bottle suitable for aseptic cold containers. The AD calcium beverage packaging bottle suitable for aseptic cold containers includes: a bottle body, the bottle body being narrower at the top and wider at the bottom, a bottle mouth being provided on the bottle body, a filling mark being provided below the bottle mouth, a grip groove being provided on the middle surface of the bottle body, the grip groove surrounding the bottle body, and an inwardly recessed anti-swelling groove being provided at the bottom of the bottle body; in order to solve the problem that ordinary beverage packaging bottles in the prior art are prone to oxidation of the liquid due to light transmission during use, this application designs a semi-transparent layer. By setting the semi-transparent layer, the overall light transmission of the bottle body can be reduced, thereby preventing the liquid from oxidizing and protecting the flavor. Furthermore, in order to avoid leakage due to compression or temperature changes during transportation, an auxiliary sealing part is further designed. By setting the auxiliary sealing part, gaps can be effectively compensated to prevent leakage.
