摘要： An assembly backlighting a liquid crystal flat panel display or other such arrangement requiring backlighting is disclosed herein. The assembly includes a plurality of light pipes and is capable of a multi-mode operation as well as achieving an enhanced dimming. This assembly is composed of two or more light pipes placed in a stacked configuration. Each light pipe has a set of specially configured microprisms which, cooperating with the light pipe, provides an efficient backlighting technique with a controllable degree of collimation. The disclosed assembly is particularly useful for displays which require a very bright backlighting, a wide dimming range and which must be capable of illuminating a given active area with light of different spectra.

摘要： Disclosed is a transmissive type display which uses ambient light for enhanced backlighting and which can be used with or without an artificial light source which is either built-in or external to the unit. The backlighting display assembly includes a light pipe with an arrangement of immediately adjacent microprisms serving as the back surface of the light pipe and a light injecting system. The backlighting system may also include a compensating plate or film which also has an immediately adjacent surface profile complementing that of the light pipe. The compensating plate, placed on top of the light pipe, is used to provide uniform illumination. Since outdoor ambient light provided by the sun usually comes from overhead, a light bending film may also be included in the backlighting system so that the display utilizes the overhead light effectively.
