摘要： An integrated optical assembly including a light management component with an entry surface and a light delivery component having an exit surface attached to the entry surface of the light management component is disclosed The light management component and the light delivery component are attached together in a manner that defines voids between the entry surface of the light management component and the exit surface of the light delivery component. The voids between the light management component and the light delivery component may provide an air interface over substantial portions of the entry surface of the light management component.

摘要： Methods for fabricating an optical film characterizable by a relationship between gain and thickness to prism pitch ratio (S/p) that varies cyclically are described. The thickness and the prism pitch of the optical film are selected based on the relationship between gain and S/p ratio, to obtain a desired gain. The optical film is formed having the S/p ratio that provides the desired gain.

摘要： A directly illuminated display unit has a display panel and one or more light sources disposed behind the display panel. A diffuser is disposed between the light source unit and the display panel and a light diverting layer is disposed between the one or more light sources and the diffuser. The light diverting layer has light diverting members on a first side of the light diverting layer facing the diffuser. Surfaces of the light diverting members are disposed at more than one angle relative to a normal to the light diverting layer and also include one or more sharp changes of surface slope. The light diverting members spread the illumination light so as to be more uniform. Different light diverting members can have different apex angles. Also, different sides of a light diverting member can have best fit centers of curvature that are non-coincident.

摘要： An optical device for collecting light and selectively outputting or concentrating the light. A layer has an optical index of referaction n1, and top, bottom and side surfaces defining an angel of inclination φ. A back surface spans the top, bottom and side surface. A first layer is coupled to the bottom surface of the layer and has an index of refraction n2. The first layer index n2 causes light input through the back surface of the layer to be preferentially output into the first layer. A second layer is coupled to the bottom of the first layer and selectively causes output of light into ambient. Additional layers, such as alight polarization layer, a polarization converting layer and a post LCD diffuser layer can be used to make preferential use of polarized light of diffuse light having passed through the LCD layer to enhance viewing of the output light.

摘要： A light emitting diode (LED) array comprises an array of LEDs mounted to a substrate. The LEDs emit light in a direction generally perpendicular to the substrate. An optical sheet is disposed over the LEDs. At least a portion of light entering one side of the optical sheet from the LEDs is guided within the optical sheet in a direction generally parallel to the substrate. Light extraction features direct light from the optical sheet in a generally forward direction. Such an array is useful for several applications, including space lighting, direct information display and backlighting of liquid crystal displays. The light spreading effect of the optical sheet reduces the amount of black space between LED pixels.

摘要： In a directly-illuminated liquid crystal display (LCD), for example an LCD monitor or an LCD-TV, a number of light management layers lie between the light source and the LCD panel to provide bright, uniform illumination. The light management layers, including, for example, a diffuser, a reflective polarizer and a brightness enhancing layer, are contained in a light management unit that is formed from two subassemblies. The two subassemblies each contain a substrate and are attached together so as to leave a gap between the two subassemblies. The diffuser is located in one of the subassemblies, and the other light management layers may be in either of the subassemblies, or may be disposed in the gap between the subassemblies.
