A pulse discharge panel display for producing a color TV picture with high luminance and luminous efficacy

A new addressing method has been studied, making use of the internal memory obtained by operating with repetitive pulse discharges, applied to gas-discharge panels having a three-electrode positive-column structure. Using this method, color TV pictures with 64 gray levels and a contrast ratio of 42:1 have been produced on a panel with 59 × 50 cells, each color picture element consisting of four cells (two green cells, one red, and one blue). In operation a peak area luminance of 70 fL and a luminous efficacy of 0.35 lm/W were obtained with an average power consumption of 110 mW/cm
