55.1: Invited Paper: High-Luminance and Highly Luminous-Efficient AC-PDP with DelTA Cell Structure

To improve the performance of PDPs, we developed an AC-PDP with the Delta Tri-color Arrangement (DelTA) cell structure and arc-shaped electrodes. The experimental panel has a pixel pitch of 1.08 mm and luminous efficiency of 3 lm/W at a luminance of 200 cd/m2. Moreover, its peak luminance can be greater than 1000cd/m2.

High‐luminance and highly luminous‐efficient AC‐PDP with DelTA cell structure

To improve PDP performance, we developed an AC-PDP with the Delta Tri-Color Arrangement (DelTA) cell structure and arc-shaped electrodes. The experimental panel has a pixel pitch of 1.08 mm and luminous efficacy of 3 lm/W at a luminance of 200 cd/m 2 despite its conventional gas mixture of Ne and Xe (4%) and conventional phosphor set. Moreover, its peak luminance can be greater than 1000 cd/m 2 . The strong dependence of luminous efficacy on the sustain voltage is also discussed in this paper.

11.1: Highly Luminous‐Efficient AC‐PDP with DelTA Cell Structure Using New Sustain Waveforms

Use of new sustain waveforms raised luminous efficacy by 2.5 times in a 9.8-inch AC-PDP with the Delta Tri-color Arrangement DelTA cell structure. A luminous efficacy of 3.5 lm/W at a luminance of 230 cd/m2 and at a sustain frequency of 5 kHz was achieved with a sufficient static margin.
