  • Patent number: 7498609
    Abstract: An LED comprises a semiconductor region including an active layer for generating light. An anode is arranged centrally on one of the opposite major surfaces of the semiconductor region from which is emitted the light. A reflective metal layer is bonded to the other major surface of the light-generating semiconductor region via an ohmic contact layer. Sufficiently thin to permit the passage of light therethrough, the ohmic contact layer is formed in an open-worked pattern to leave exposed part of the second major surface of the semiconductor region. A transparent, open-worked anti-alloying layer is interposed between the light-generating semiconductor region and the reflective metal layer, covering that part of the second major surface of the light-generating semiconductor region which is left exposed by the ohmic contact layer. The anti-alloying layer prevents the light-generating semiconductor region and reflective metal layer from alloying during heat treatments conducted in the curse of LED manufacture.

  • Patent number: 7206112
    Abstract: An image display device includes at least one transmissive display panel arranged at different depth positions in a direction normal to a display surface of the image display device. Each of the transmissive display panels includes a light-emitting layer that is sandwiched between a front side transmissive film and a rear side transmissive film. The rear side transmissive film has an interface with a maximum refractive index difference that causes an efficiency of light emitted from the light-emitting layer to become smaller than a front side light emission efficiency in the characteristics of light-emission efficiency, which changes with respect to a film thickness of the transmissive film due to optical interference.

  • Patent number: 7165841
    Abstract: A stereoscopic image display apparatus includes at least two linear image display devices which respectively display linear images in response to image signals. The two linear image display devices are periodically moved by a mechanical scan mechanism along a plurality of locus planes substantially parallel to each other. The mechanical scan mechanism may have a configuration which belt-drives the at least two linear image display devices fixed to a belt, or a configuration which rotationally drives the at least two linear image display devices provided on a disc. The stereoscopic image display apparatus can display a bright and extremely clear stereoscopic image without using a complicated optical system and a light transmissible display panel.
