摘要： An optical film includes a substrate layer and a plurality of optical layers stacked on the substrate layer. The at least two optical layers have microstructures that complement to each other. The optical layer close to the substrate layer is the first optical layer, and the optical far from the substrate layer is the second optical layer. The refractive index of the first optical layer is smaller than the second optical layer, and the microstructure of the second optical layer has an acute angle. Because of the arrangement of the optical layers, the contrast of light intensity can be reduced, and the uniformity can be improved. The invention also provides a backlight module and a display device including the optical film.

摘要： A light guide film for use with a light source includes a light-transmissive substrate and a light-transmissive layer. The substrate includes a top surface, and a light-incident lateral surface adapted to be disposed adjacent to the light source. The layer is disposed on the top surface of the substrate and has a light-incident lateral surface aligned with the light-incident lateral surface of the substrate. The light-transmissive layer has an inclined surface that is opposite to the substrate and that extends away from the light-incident lateral surface of the layer and obliquely toward the top surface of the substrate. The layer has a refractive index different from that of the substrate.

摘要： A light directing sheet includes a light-incident side and a light-exit side opposite to the light-incident side. The light-exit side can be divided into a middle area and two side areas along an X-axis direction. The side areas are located on both sides of the middle area. A plurality of strip structures are protruded and arranged on each of the side areas, and the strip structures are arranged along the direction of the X axis and elongated along the direction of a Y axis perpendicular to the X axis. The strip structures are in a staggered arrangement of high microstructures and low microstructures with a height lower than the high microstructures. Through the type and arrangement of the strip structures on the light directing sheet, the light with an excessively large angle can be refracted again. A backlight module and a display device include the light directing sheet.
