Abstract : The report describes the design, construction, and successful operation of a plasma display module having 256 by 1024 randomly addressable elements with a resolution of 33 lines per inch. The capacitively coupled display elements are neon orange with a peak light intensity of about 60 foot-lamberts and a contrast ratio of about 20 to 1. The module can be stacked on its long axis with other modules to form larger display panels. The discontinuity of the display matrix between modules can be made as small as 0.030 inch. Complete drive electronics were fabricated for one display module. It is organized so that any one of the quarter million elements can be randomly selected and written or erased. The write cycle time is 355 microseconds and the erase cycle time is 230 microseconds. The update time for writing 10 percent of the display module is 9.5 seconds. The sustain driver for the panel is capable of lighting up to 50 percent of the panel without significant loss of operating margin. (Modified author abstract)
