Good quality TV pictures using a gas-discharge panel

Abstract

Good quality real-time TV pictures were displayed on a matrix gas-discharge panel of 80 columns and 212 rows. The 2.4- in wide × 6.3-in high Burroughs Self-Scan panel displays part of a TV picture, has a peak luminance of 8 fL, and a maximum usable contrast ratio of 40:1. The matrix is addressed one line at a time, using standard TV interlace and a continuous gray scale. Picture quality is comparable to that of a monochrome 25-in CRT and the picture can be readily viewed in a normally lit room. Dominant emission is from the neon gas; panel color is orange-red. Panel luminance and luminous efficiency are low compared to a CRT. The circuitry is more complicated--it must store the video signal and provide a total of 300 V for each display element.
