14.1: Invited Paper: Development of Plasma Tube Array Technology for Extra‐Large‐Area Displays

We developed the basic technology for a plasma tube array that could be used to produce emissive, extra-large-area displays. The cell design for high luminous efficacy was developed and luminous efficacy of 5.4 lm/W was achieved for a 20 cm test tubes array. Basic techniques, such as those to produce the tube structure, flexible electrode substrate, drive waveform, were also developed. A high luminous efficacy of 3.7 lm/W and lightweight of 0.6 kg were achieved for a 43-inches-diagonal test array.
