41.4: 50-Hz Flicker Reduction for PDP and Evaluation System Development

In this paper, we describe the optimum sub field sequences for displaying at 50-Hz basis rate on PDP: A modified duplicated sub field sequence is represented with much reduction of the large flicker against 50-Hz basis video signals. Further in the designing procedure, the simulation method for 50-Hz flicker has developed and verification result between simulation and measurement meets the expectations well.

30.2: Invited Paper: High‐Performance 55‐inch Diagonal WXGA PDP with Extended ALIS Technology

We have developed a high performance 55-inch diagonal WXGA PDP module with a novel structure of Extended ALIS (Alternate Lighting of Surfaces) technology. The new cell structure using a common bus electrode concept was invented with a new driving scheme aiming at progressive lighting. A motion adaptive data processing method was also developed to suppress motion artifacts such as color contour or hatching degradation. The newly developed 55-inch WXGA panel has 1,000 cd/m2 peak luminance and 160 cd/m2 full screen white luminance with 9,000 K color temperature at 350W display power consumption.

High‐performance 55‐in. diagonal WXGA PDP with extended ALIS technology

— We have developed a high-performance 55-in. diagonal WXGA PDP module with a novel structure by using Extended ALIS (Alternate Lighting of Surfaces) technology. The new cell structure that uses the common bus electrode concept was invented with a new driving scheme aimed toward progressive lighting. A new method of reducing dynamic false contour (DFC), motion adaptive subfield coding, was also developed. The newly developed 55-in. WXGA panel has a 1000-cd/m2 peak luminance and a 160-cd/m2 full-screen white luminance with a 9000 K color temperature at a 350-W display power consumption.
