Experimental HDTV Display with a 33-Inch Gas-Discharge Panel using a Pulse Memory Drive Scheme

Abstract

Hi-Vision pictures have been reproduced experimentally on a 33-inch-a dc gas-discharge color panel with 1024 x 800 cells of 0.65 mm pitch. The panel uses a pulse memory-drive scheme as the first step towards making a Hi-Vision flat-panel display. About 40 percent of the area of an original Hi-Vision picture with the standard 1125 lines/60 fields was displayed because of the limited number of panel cells. The memory operation over the whole effective area of the panel was stable for the two-line-at-a-time access drive, due to the introduction of a two-step sustain pulse and improved fabrication techniques. Signal processing circuits developed for the pulse memory panel allowed fairly high-quality pictures to be reproduced on the panel.
