A 60 line per inch plasma display panel

Gas discharge plasma display panels have been under development at Owens-Illinois for several years. This display device offers many advantages including: 1) tube depth (approximately ½ in) essentially independent of display size; 2) random write capability; 3) controlled information storage; 4) selective erase and bulk erase capability; 5) positive registration of displayed information; and 6) rear projection and/or printout capability. Panels, now available (DIGIVUE® display/memory unit), with 33⅓ and 40 electrode lines per inch are appropriate for many applications. However, a somewhat higher resolution of 50 or 60 lines per inch is desired for most general-purpose individual console displays when the number of lines in
X
or in
Y
exceeds several hundred. The lower density Owens-Illinois panels are constructed from a parallel plate structure that was selected because of its compatibility with high volume manufacturing processing. This study indicated that the same basic structure could be used at resolutions up to 60 lines per inch. Design dimensions were optimized for this higher resolution and good dynamic operation was obtained. Process techniques were developed to produce panels with 256 by 256 lines and 512 by 512 lines. Several panels of each of these sizes were fabricated and evaluated. The performance of these 60 line per inch panels was comparable to that of the 33 line per inch panels.
