  • Patent number: 11532754
    Abstract: An array substrate includes a substrate, an active layer, and an amorphous silicon shielding layer. The substrate has a first surface and a second surface, which are opposing to each other. The active layer is over the first surface of the substrate. The amorphous silicon shielding layer includes amorphous silicon, and is between the active layer and the substrate, or alternatively is disposed over a side of the substrate proximal to the second surface of the substrate. An orthographic projection of the amorphous silicon shielding layer on the first surface at least partially and preferably completely covers an orthographic projection of the active layer on the first surface such that the amorphous silicon shielding layer shields a light from shedding onto the active layer.

  • Patent number: 11513264
    Abstract: Methods are provided for forming a particular multi-layer micron-sized particle that is substantially transparent, yet that exhibits selectable coloration based on its physical properties. The disclosed physical properties of the particle are controllably selectable refractive indices to provide an opaque-appearing energy transmissive material when pluralities of the particles are suspended in a substantially transparent matrix material. Multiply-layered (up to 30+ constituent layers) particles result in an overall particle diameter of less than 5 microns. The material suspensions render the particles deliverable as aspirated or aerosol compositions onto substrates to form layers that selectively scatter specific wavelengths of electromagnetic energy while allowing remaining wavelengths of the incident energy to pass.

  • Patent number: 11448797
    Abstract: A viewing lens and method for treating lenses to minimize glare and reflections for birds with tetra-chromatic vision. The anti-reflection lens is treated to with a coating on the surface. The coating is configured to enable the lens surface to be less perceptible to a bird with tetra-chromatic vision by reducing reflections therefrom. The lens treatment includes applying an anti-reflective coating in multiple coats. The coats comprise an adhesion composition, a low index composition (such as SiO2), a high index composition (such as ZrO2), and a superhydrophobic composition that are applied in subsequent layers of varying nanometer thicknesses. The treated lens exhibits minimal reflection properties in the visible range of the electromagnetic spectrum and almost no reflection in the UV-A range. This creates a lens surface that is difficult for birds with tetra-chromatic vision to see a reflection therefrom.

  • Patent number: 9529123
    Abstract: A lens blank is proposed, having a first face, an opposite, second face, and an edge inbetween, the first face possessing a final curvature and being coated, in this order, with an antireflection coating, a top coating, and a temporary grip coating. The antireflection coating has a stack of alternating antireflection layers with an outermost layer, whereas the top coating is selected from a group including hydrophobic, oleophobic and dirt repelling coatings. The temporary grip coating and the outermost layer of the antireflection coating are made from one and the same coating material. In this way the temporary grip coating effectively serves to provide sufficient adhesion to the blocking material on the block piece in the processing steps, and can easily be removed from the processed lens upon deblocking without degrading the repelling properties of the top coating.

  • Patent number: 9492978
    Abstract: A method for fabricating a Fresnel lens or other lens having a structured surface such as refractive and/or diffractive bi-focal or other multi-focal lenses includes press-coating the structured surface with a low or very low refractive index coating material. The coating is sufficient thick to adequately cover the structured surface so that a smooth coating surface with good optical properties is obtained, for example in the case of a Fresnel structure a thickness greater than 1.5 times and less than 5 times the Fresnel structure height, and is cured in situ. A film, e.g., of PET, PC or PU or a film stack, e.g. a TAC/PVA/TAC film stack is prepared and a heat melting adhesive is applied to the side of the film or film stack to be contacted with the coated structured surface of the lens blank. The film or film stack is then laminated to the cured coating.

  • Patent number: 9400343
    Abstract: Durable hydrophobic antireflection structures for optical elements, optical windows, and front sheets of encapsulated photovoltaic and photonic devices are disclosed which can minimize reflection losses over the entire accessible portion of the solar spectrum simultaneously provide self-cleaning and finger-print-free surface. Reduced reflectance and self-cleaning surfaces are resulted from coating the front sheet of encapsulated device with combination of nonporous and porous nanostructured materials such as silicon dioxide nanorods and PTFE. Step-graded antireflection structures can exhibit excellent omnidirectional performance, significantly outperforming conventional quarter wavelength and low-high-low refractive index coatings. Methods of constructing nanostructured durable optical coatings with hydrophobic surfaces are disclosed that can cover large-area ridged and flexible substrates.

  • Patent number: 9389353
    Abstract: A method of fabricating a transparent and birefringent mineral solid thin layer comprises the following steps: a) preparing a colloidal solution constituted by anisotropic mineral nanoparticles in suspension in a dispersion liquid; b) depositing the colloidal solution on a surface of a substrate by spreading as a thin layer while applying directional shear stress tangentially to the surface of the substrate so as to deposit the colloidal solution as a liquid thin layer on the surface of the substrate, the value of the shear stress and the concentration of mineral nanoparticles in the colloidal solution being determined in such a manner as to cause the anisotropic mineral nanoparticles to be aligned along the direction of the shear stress tangential to the surface of the substrate; and c) drying the liquid thin layer by evaporating the dispersion liquid.

  • Patent number: 9040115
    Abstract: Disclosed is a negative C-type retardation compensator for a liquid crystal display. The negative C-type retardation compensator for the liquid crystal display includes polyarlate having a thio group or a sulfur oxide group in a polymer main chain thereof. Accordingly, the retardation compensator has an absolute value of negative retardation that is larger in a thickness direction that a retardation compensator which includes polyarylate having no thio group or sulfur oxide group in a polymer main chain thereof even though the retardation compensator having the thio group or sulfur oxide group and the retardation compensator having no thio group or sulfur oxide group are the same as each other in thickness. Thereby, the negative C-type retardation compensator for liquid crystal displays is capable of being desirably applied to the liquid crystal displays.
