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： A display includes an optical film (218) that has a surface structure (222), such as a prismatically structured surface for increasing the brightness of the display. The structured surface is bonded to an opposing surface (228) of a second film (220) using a layer of adhesive (226), by penetrating the structured surface into the adhesive layer to a depth less than a feature height of the structured surface. The bonded film structure provides additional strength to the films and reduces the possibility of film damage during display assembly.
摘要翻译：显示器包括具有表面结构（222）的光学膜（218），例如用于增加显示器的亮度的棱镜结构的表面。使用粘合剂层（226）将结构化表面结合到第二膜（220）的相对表面（228），通过将结构化表面穿透到粘合剂层中至小于结构化表面的特征高度的深度。粘合膜结构为膜提供了额外的强度，并降低了显示组件期间膜损坏的可能性。

摘要： In a directly-illuminated liquid crystal display (LCD) (100), for example an LCD monitor or an LCD-TV, a number of light management layers (120) lie between the light source (116) and the LCD panel (102) to provide bright, uniform illumination. The light management layers, including, for example, a diffuser (122), a reflective polarizer (124) and a brightness enhancing layer, are contained in a light management unit (200) that is formed from two subassemblies (202, 204). The two subassemblies each contain a substrate (210, 212) and are attached together so as to leave a gap (206) 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.
