Advances in Materials Research for Displays From Serendipity to Materials by Design

摘要

New materials have been developed for PDP for fast addressing and power reduction. They show the transition in R&D from materials invented accidentally to materials-by-design. Cathodeluminescence on MgO crystals is used to compare thermally assisted recombination and tunneling. Bethe Salpeter equations (BSE) are used to predict the exciton properties of mixed oxides like MgCaO. Using new materials an ultra-thin (300 um) and flexible Shadow-Mask PDP has been realized. The same device is also operated in a reverse mode, where high energy radiation is imaged, using the Gaseous Electron Multiplier (GEM) effect in the Townsend mode.
