ABSTRACT:
A gas plasma display panel heater device for use with a gas plasma panel display, and methods for using and mounting the same. The gas plasma display panel has a display viewing area, external connection and heather. The gas plasma display heater device includes a thermally conductive layer, preferably a foil or coating, arranged and configured to substantially envelop the gas plasma display panel while not covering the display viewing area. The gas plasma display heater device is operative to conduct heat generated by the heater to other portions of the gas plasma display panel. The plasma display heater further includes a supplemental heater device. The supplemental heater device includes a heating element which is formed from an electrically resistive material such that, when a current is passed through the heating element, the same will generate heat. The supplemental heater also has electrical leads electrically connected with the heating element. The electrical leads are operable to conduct a current through the heating element. The heating element is mounted on a selected portion of the gas plasma display panel, preferably on or near the coldest portion thereof.
