Abstract: An illumination apparatus for an LCD/organic display (4) having a grid of high intensity LED lamps (1) covered by a Frenzel lens (2) and a polycarbonate glass diffuser (3). The illumination apparatus is placed behind an LCD/organic display (4) for the purpose of emitting a high intensity but uniform light, thereby eliminating any “hot spots” on the display screen (4). A covering, preferably made of clear polycarbonate glass 5, is then placed over the LCD/organic display (4) to protect the display from dust, dirt, scratches and other everyday happenings. This illumination apparatus enables LCD/organic displays (4) to be built with much larger screens than currently possible.

Abstract: A remotely controlled electronic display sign which operates with a plasma display and which provides for humidity control and the like allowing the sign to be used in various environments. The sign is essentially self-contained and includes those components necessary for enabling a display of desired material from a remote control source. A controller in or associated with the sign is accessible either electrically, or through satellite transmission or other wireless transmission from the remote source which allows the display of the sign to be changed at will. Thus, an operator at a remote source may, with the aid of a pre-prepared graphic design, transmit that design to the controller at or associated with the sign for display of that graphic information.

Abstract: This invention provides for a light emitting device which comprises an envelope of electrically insulative material which defines within its boundaries an ionization chamber. A noble gas is disposed within the chamber and two spaced electrodes are located on the light emitting device such that the electrodes are in electrical communication with the interior of the chamber. At least one conductive member is disposed on the device and arranged to define a tortuous path between the two electrodes but without providing a direct electrical connection between the two electrodes. When a high frequency alternating voltage is applied to the electrodes the electrical interaction between the electrodes and the conductive member causes an ionization path between the electrodes to substantially follow the tortuous path.
