Abstract: The warning device contains a plastic sheet having a number of through holes and/or a number of magnetic elements positioned alternately along the edges. On a major surface of the plastic sheet, one or more reflective plastic shapes are affixed by high-frequency fusion along which a number of light emitting diodes are arranged beneath and protected by transparent covers. The light emitting diodes draws electricity from a battery or from a cigarette lighter of a vehicle. When the vehicle is broken down, the warning device can be attached to a metallic surface by the magnetic elements, or it can be hanged or tied to something by running a number of threads through the through holes.

Abstract: The present invention provides an address electrode structure for a plasma display panel. The address electrode structure of the present invention has two conductor lines that are partially connected together. The connected part approximates the adjoined parts of the X electrode and the Y electrode in the illumination units.
