Title:
PLASMA DISPLAY AND ITS DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2004/109636
Kind Code:
A1
Abstract:
A plasma display in which emission efficiency is enhanced greatly while suppressing cost increase of a drive circuit. The PDP (1) comprises an enclosure formed by pasting a front plate (10) and a back plate (40) disposed oppositely through a barrier wall (30), and the gap between the front plate (10) and the back plate (40) is filled with rare gas, e.g. Ne, Xe or He. On the back plate (40), a group of retaining data electrodes (52) are juxtaposed to respective data electrodes (51). A data drive circuit (4) delivers a data voltage selectively to the data electrode group (51) during a write period based on image data of respective subfields being inputted sequentially line by line. A retaining data drive circuit (5) applies retaining data pulses collectively to the retaining data electrode group (52) during a retaining period.
