Plasma display panel and imaging device using the same
View Patent ↗A plasma display panel and an imaging device realize a high luminous efficiency, a long lifetime and stable driving. The plasma display panel uses a discharge-gas mixture containing at least Xe, Ne and He. A Xe proportion of the discharge-gas mixture is in a range of from 2% to 20%, a He proportion of the discharge-gas mixture is in a range of from 15% to 50%, the He proportion is greater than the Xe proportion, and a total pressure of the discharge-gas mixture is in a range of from 400 Torr to 550 Torr. A width of a voltage pulse to be applied to an electrode serving as an address electrode is 2 μs or less.
1. A plasma display panel comprising:
a discharge space;
a plurality of discharge electrodes including an electrode having a function of addressing;
said discharge space being filled with a discharge-gas mixture containing at least Xe, Ne and He; and
a circuit which applies a voltage pulse to said electrode having a function of addressing, thereby producing a write-discharge in said discharge space,
wherein a Xe proportion of said discharge-gas mixture is in a range of from 2% to 20%,
a He proportion of said discharge-gas mixture is in a range of from 15% to 50%,
said He proportion being greater than said Xe proportion,
a total pressure of said discharge-gas mixture is in a range of from 400 Torr to 550 Torr, and
a width of said voltage pulse is 2 μs or less.
2. A plasma display panel according to claim 1 , wherein said Xe proportion of said discharge-gas mixture is in a range of 2% to 14%.
3. A plasma display panel according to claim 1 , wherein said Xe proportion of said discharge-gas mixture is in a range of from 6% to 14%.
4. A plasma display panel according to claim 1 , wherein said Xe proportion of said discharge-gas mixture is in a range of from 6% to 12%.
5. An imaging device comprising a plasma display panel according to claim 1 , and a driving circuit including at least a control circuit, to drive said plasma display panel.
6. An imaging device comprising a plasma display panel according to claim 2 , and a driving circuit including at least a control circuit, to drive said plasma display panel.
7. An imaging device comprising a plasma display panel according to claim 3 , and a driving circuit including at least a control circuit, to drive said plasma display panel.
8. An imaging device comprising a plasma display panel according to claim 4 , and a driving circuit including at least a control circuit, to drive said plasma display panel.
