New Pdp Cell Structure For High Luminous Efficacy With Low Voltage Driving

We propose a new PDP cell structure named DIDE (Dual Ignition Discharge Electrodes) structure with a efficacy. long electrode gal) to realize a high luminous efficacy Suggested DIDE structure basically has a long electrode gap (200 mu m similar to 400 mu m), nevertheless, because of auxiliary electrodes,formed on the front panel, can be driven at relatively low voltage. The discharge characteristic of DIDE structure was much different from that of conventional structure, which was analyzed by IR emission images using IICCD (Image Intensified Charge coubled Device). The study can explain some particular characteristics of DIDE structure.As a result, the long electrode gap and low voltage effect can be expected in DIDE structure, and a very high luminous efficacy of 7.5 lm/W has been achieved in monochrome green lest panel adopting the new cell structure with Ne-Xe (12%) mixture at 400 torr.
