Improvement of luminous efficiency and radiation transport in PDP

Summary form only given, as follows. Using two- and three-dimensional fluid simulation codes (FL2P, FL3P), we have suggested several new PDP cell structures that have higher efficiency than conventional PDP cell. Varying electrodes and pulse shapes, arch-shaped long discharge path can be formed in the plasma region. Arch-shaped long discharge path reduces the power consumption and increases the discharge efficiency in cathode. Because the proximity between generated Xe* and phosphor layer is also improved, we have obtained high luminance and luminous efficiency. Furthermore, effective cutting of central region in large area sustain electrodes makes two discharge regions near the barrier ribs, on which phosphor layer is deposited. Using these kinds of new structures, we have achieved 80-100% improvement in luminous efficiency in simulation. For the accurate radiation trapping simulation of xenon (Xe) excited species in PDP cell, we have calculated full radiation transport using Holstein´s equation instead of effective decay time approximation. From the simulation with full radiation transport, there are differences in space distribution of Xe*(/sup 3/P/sub 1/) and photon flux compared with conventional calculation.
