摘要： A composite laminate makes it possible to obtain transparent layered elements with diffuse reflection that can be used in esthetic and/or antireflection glazings, or even in transparent projection screens. The composite laminate includes an organic polymeric support, a layer and a first transparent organic polymeric substrate. The dielectric layer is disposed between the support and the substrate. The dielectric layer has a refractive index greater than the refractive index of the first substrate. The adhesive energy between the dielectric layer and the support is less than the adhesive energy between the dielectric layer and the substrate.

摘要： A method of making a light converting optical system is described. The method includes providing a layered light trapping structure comprising a first optical layer with a plurality of linear grooves having triangular cross-sections for reflecting and deflecting light through total internal reflection and refraction. A diffuse reflector, made from a thin sheet of diffuse reflective material, is placed parallel to the first optical layer. A light converting film, positioned between the first optical layer and the diffuse reflector, contains an active layer with first and second light converting semiconductor materials of different bandgaps. The thickness of the active layer is below the minimum required to absorb all visible spectrum light in a single passage. The method further involves providing a light source and positioning the layered light trapping structure to receive energy from the light source.

摘要： A light diffusion sheet 43 includes, at least in its first surface 43a, a plurality of recesses 22 formed in a substantially inverted polygon pyramid or in a substantially inverted truncated polygon pyramid. The ridge 23 parting the plurality of recesses 22 has a recessed shape between the intersections 23a, with respect to a straight line connecting the intersections 23a of the ridge 23. Where P is the arrangement pitch of the plurality of recesses 22 and Wr is the dimension occupied by a curved portion at the top portion of the ridge 23 in the arrangement direction of the plurality of recesses 22, a ratio Wr/P is 0.3 or less. The maximum height difference d between the ridge 23 and the straight line connecting the intersections 23a of the ridge 23 is 1 μm or more and 10 μm or less.

摘要： A wire grid structure and a manufacturing method therefor, and a projection screen are provided. The manufacturing method includes: extruding a molten mixed material body in a melt extruder to a casting roll to form a casting piece; patterning the casting piece by means of an impression roll to form a precursor having a preset wire grid structure pattern, where the precursor is wound on the impression roll and has a first dimension in a height direction; stretching the precursor by a first group of stretching rolls and a second group of stretching rolls in two opposite directions along a direction perpendicular to the height direction to form the wire grid structure, a preset distance being configured between the first group of stretching rolls and the second group of stretching rolls. The wire grid structure has a second dimension in the height direction that is greater than the second dimension.
