An optical module including a plurality of laser diodes and outputting optical beams emitted from the laser diodes includes a radiator unit for radiating heat and a case enclosing the optical module. The case has a first attachment surface to which a red laser diode is attached, a second attachment surface to which a green laser diode is attached, and a corner part where the first and second attachment surfaces intersect with each other. The optical module has a first attachment part, for connecting the case to the radiator unit, in the vicinity of the corner part.

Optical module and scan-type image projection display device

A fixing structure of an optical component is composed of a device chassis; a holder holding an optical component; first and second plate parts for joint to the device chassis and a connecting part of both the plate parts are formed in the holder; a plurality of joint holes are formed in the second plate part; a U-groove into which the connecting part of the holder is fitted and a plurality of through-holes are formed in the device chassis; and an adhesive that is extended in a circular columnar shape and is made by inserting the holder into the U-groove of the device chassis, and applying a UV-curing adhesive in such a manner that the UV-curing adhesive is bonded to the first plate part of the holder and is continuous to the inside of the joint hole via the inside of the through-hole, and radiating UV light along the through-hole.

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.

For improving a cooling efficiency of a display panel in a flat-type image display, various substrates and an image display element are disposed within a thin-sized housing thereof, including: a display panel; a chassis supporting the display panel from a rear surface side thereof; a front surface-side cover on a front side of the display panel; a rear surface-side cover on a rear side of the display panel; an image display element connected to the display panel; a display driver substrate connected to the display panel, and on a surface thereof opposite to the chassis are provided circuit parts; a power source substrate, supplying driving power to the display driver substrate and the image display element, and on a surface thereof opposite to the chassis are provided circuit parts thereof; and a first insulator board opposite to the display driver substrates and the power source substrate of the chassis.

Image display

A flat panel display apparatus includes a plasma display panel, a power supply substrate, a signal processing substrate, a Y sustaining substrate, and an X sustaining substrate. The power supply substrate, the signal processing substrate, the Y sustaining substrate and the X sustaining substrate are arranged at a back of the plasma display panel. When viewing the plasma display panel from the back, the power supply substrate is arranged at a center portion of the plasma display panel, the Y sustaining substrate is arranged at one of a left and right side of the plasma display panel, the X sustaining substrate is arranged at the other of the left and right side, and the signal processing substrate is arranged under the X sustaining substrate. A circuit substrate other than the power supply substrate, the Y sustaining substrate, and the X sustaining substrate is arranged under the power supply substrate.

Flat panel display

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.

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.
