    摘要: A flat panel display screen apparatus with optical junction and removable backlighting assembly. An optical junction is formed between a permanently housed light source within a display assembly and a removable light pipe when inserted into the display assembly. The optical junction is formed from a reflective film attached along the long axis of the light source and extends past a side of the light source to cover a gap between the light source and the light pipe. Another reflective strip is placed along and extends past an edge of the light pipe to bridge the gap. The reflective material is used to reflect stray light into the light pipe. The present invention also includes a display subsystem with a light pipe in a removable door, the removable door assembly adapted for insertion into and removal from the display assembly and comprising a light pipe for optically coupling with the light source for illuminating the flat panel display matrix with the back-light and wherein the light source remains secured within the display assembly upon removal of the removable door assembly so that a power supply line to the light source is not disturbed upon removal of the removable door assembly and further comprising a control circuit responsive to the sensor for turning the light source on when the control signal is at a first state and for turning the light source off when the control signal is at a second state.

    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.
