In a PDP device, a technique capable of more efficiently performing address energy control according to contents of a display image (display data) to reduce the address energy. In the PDP device, as an address energy recovery circuit, a plurality of address energy control circuits (B1 to Bn) are provided corresponding to a plurality (n) of regions (H1 to Hn) into which a screen area (R) and a group of address electrodes are divided in a horizontal direction. For each of the regions (H) of which the address energy recovery circuits (B) are respectively in charge and for each of subfields, an address pulse switching load (Q) corresponding to that region (H) is determined, and then, according to the magnitude of the load (Q), the operation of the address energy recovery circuit (B) is ON/OFF-controlled.

A novel method for driving a plasma display panel and a plasma display device for reducing background emission due to a reset discharge are disclosed. In a three-electrode type PDP, a third (Z) electrode is provided between a first (X) electrode and a second (Y) electrode between which a discharge is caused to occur and when a reset discharge is caused to occur, the third electrode is set to a potential that makes the third electrode function as an anode for the electrode used as a cathode during the reset discharge between the first and second electrodes.

Provided is a seal structure which can reduce the thickness of an electronic device, can be easily assembled and disassembles, and can exhibit an excellent seal performance. Thus, the seal structure for an electronic device, which seals a gap between a flexible wiring substrate inserted to a through-hole provided in a case member of an electronic device and the through-hole, is comprised of an annular gasket composed of a rubber elastic material, a part of which is integrally molded with the flexible wiring substrate, and a retainer plate for retaining the gasket in conjunction with the case member.

Disclosed is a body structure for a dump truck (1) having a body frame (3). The body structure is provided with hinge pins (5) to be located toward a rear of the body frame, a body (2A) to be tiltably disposed on the body frame via the hinge pins and to be adapted to load payload (9), and stiffening members arranged on outer surfaces of the body. The body is constructed at least of a floor board (62a), a front board (62b), side boards (62c), and a canopy (62d). The stiffening members include side-board stiffeners (61) connecting upper portions of elongated joints between the side boards and the front board to portions of elongated joints between the side boards and the floor board. The latter portions are located rearward of positions laterally corresponding to a barycentric position (G) of the payload (9) in a longitudinal direction of the body.

According to one embodiment, a display device includes an image data generating unit and a display unit. The image data generating unit generates image data on an image. The display unit presents a video including the image data to an image viewer on a moving body to superimpose the video on an actual outside scene. The image data includes a first display object and a second display object. The first display object includes a lower part object. The lower part object has a lower part, an upper right part and an upper left part. A length of the lower part along a normal direction is longer than lengths of the upper right and upper left parts. The second display object is disposed in the image with reference to a display position of the first display object. The second display object includes information on the moving body.

According to one embodiment, a display device includes an image projection unit. The image projection unit is configured to project a light flux toward one eye of a human viewer by using a projection plate to reflect the light flux. The light flux includes an image including a display object having a vanishing point. The projection plate is reflective and transmissive. The image projection unit is configured to dispose the vanishing point of the display object at a position different from a position of a vanishing point of a background image viewed by the human viewer through the projection plate.
