  • Publication number: 20130003022
    Abstract: A polarizing prism is shaped in the form of a hexahedron. A polarizing beam splitter film (PBS film) is arranged approximately in a diagonal direction of the hexahedron. The polarizing prism holds a relationship of A<B when the dimension thereof in an outgoing direction (Y direction) of a light beam to a screen is A and the dimension thereof in an incident direction (X direction) of a light beam from a light source is B. For example, the polarizing prism is shaped in the form of a rectangular parallelepiped. At a plane on which the light beam is launched from a scanning mirror, one end of the PBS film is placed so as to intersect with the incident plane at an angle of approximately 45° at a position deviated inside by a difference between the dimensions A and B from the end of the incident plane.

  • Patent number: 8159622
    Abstract: Space is decreased in the direction of thickness on a side of a substrates mounted on a back of a flat panel display to adapt requirement for increasing and thinning its size, and most flat panel displays forcibly radiate heat with a fan provided thereon. The present invention provides a flat panel display having fewer heat radiating fans to secure a channel for causing a heat radiating air to flow. Portions where electronic circuit device on a back of a display panel are mounted are divided into three: left; center; and right portions; with a main frame as a border, the electronic circuit device are constructed of four module substrates, the substrate which is the greatest in heating value in the four module substrates (hereinafter referred to as a substrate) is arranged in the center portion and the substrates which are the smallest and the second smallest in heating value therein are arranged in the same portion.

  • Patent number: 8066234
    Abstract: A large-screen image display apparatus includes a stand for supporting the display module, which has a leg portion. The leg portion of the stand is inserted into the main frame. The leg portion and the main frame are fastened together at a first screw hole formed through the leg portion. In addition, the leg portion and a fixing part of the outer frame are fastened together at a second screw hole formed through the leg portion. The first screw hole and the second screw hole are formed on different faces of the leg portion and at different heights. This can provide a large-screen image display apparatus with a less-wobble, high-safety, high-reliability, and low-cost stand-attaching structure.

  • Publication number: 20110210024
    Abstract: There is provided a package structure for packing a flat display unit which improves workability in taking a flat display unit out of a packing box. A lower cushioning material which supports a display portion of the flat display unit from below has a manual insertion portion so that the display portion can be held at a portion close to a lifting person's body when the display portion is taken out of a lower part of the packing box. A reinforcing rib is provided on a front side of the lower cushioning material to prevent damage to the lower cushioning material due to a reduction in strength. To prevent the lower cushioning material from being taken out together with the display portion when the display portion is taken out, a recess is provided in the lower cushioning material so that the recess is caught on a bending portion in the lower part when the display portion is taken out.
