  • Patent number: 10788613
    Abstract: A planar lighting device according to an embodiment includes a light guide plate and a reflecting member. The light guide plate has an incident surface that receives light output from a light source and an output surface that outputs the light received by the incident surface. The reflecting member faces an end surface opposite to the incident surface of the light guide plate and reflects light leaking from the end surface. A plurality of first prisms are formed on an opposite surface opposite to the output surface-of the light guide plate to be away from the output surface stepwise from the incident surface to the end surface.

  • Patent number: 9669932
    Abstract: A display for viewing by a passenger from a seat on a vehicle when the display is mounted to structure in front of the passenger when the passenger is seated in the seat. The structure has a recess and a portion surrounding the recess. The display includes an electronic visual display panel for receiving a display signal and displaying information in correspondence therewith to the passenger on the electronic visual display panel. The display further includes a housing in which the electronic visual display panel is mounted or inserted, with the housing including a periphery. At least one fastener is provided including a structural fuse. The structural fuse deforms and/or fractures under force generated by a passenger's head striking the visual display panel in an accident. Due to crumple of the fuse, movement of the housing is permitted, with the display panel inserted therein, relative to the recess.
