Higher Xe content gas has been applied to an improved cell design using “T”‐shaped electrode and deep WAFFLE rib. Newly developed 50‐in. diagonal wide/XGA panels have a luminous efficacy, a panel luminance and a panel full screen white luminance of 1.8 lm/W, 900 cd/m 2 and 200 cd/m 2 respectively. The power consumption of the new 50‐in. display monitor is 348W. The image qualities, other than luminance, have been also improved by “smooth CREAR” driving method and “pure” color filter. The driving method reproduces 768 gray levels and the gradation on low luminance region is as smooth as 4000‐step gray levels. Color gamut reproducing full NTSC area and a bright‐room contrast ratio of 120:1 under ambient illumination on the screen of 150 lx have been obtained by the color filter. After all the newly developed plasma displays (PDPs here after) show high display quality and the total display performance of them, as a large‐screen TV, excels that of any other display device.
