摘要： Disclosed herein is a sheet comprising a polymeric material; light diffusing particles disposed in the polymeric material; and a non-random surface texture on a surface of the sheet; wherein the surface texture comprises hemispherical structures, partial hemispherical structures, ellipsoidal structures, immersed spherical beads, ellipsoidal beads, “bell-shape” bump, complex lens shape structures, pyramidal structures, reversed pyramidal structures, or combinations comprising at least one of the foregoing. The sheet has excellent hiding power and transmission at the same time and is suitable for LED light cover applications. The unit structures have an aspect ratio of 0.15 to 0.5 and a pitch of greater than or equal to 100 μm

摘要： In one embodiment, a graphic image display can comprise: a backlight source; a light transmitting first sheet having a viewing side and a backside, with a plurality of geometric microstructure units on the backside; and a second layer comprising a source of graphic image information. The plurality of geometric microstructure units can be selected from microlenses, polyhedral shapes, lenticular shapes, and combinations comprising at least one of the foregoing. The graphic image display can be suitable for viewing under ambient light from the viewing side alone, under backlighting alone, and in the presence of both ambient light from the viewing side and backlighting.
摘要翻译： 在一个实施例中，图形图像显示器可以包括：背光源; 具有观察侧和背面的透光第一片，背面具有多个几何微结构单元; 以及包括图形图像信息源的第二层。 多个几何微结构单元可以选自微透镜，多面体形状，透镜形状，以及包括前述的至少一个的组合。 图形图像显示器可以适用于在单独的观察侧的环境光下，单独的背光下以及在来自观察侧的环境光和背光的情况下观看。
