Abstract

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.

Claims (34)

1 . A plasma display panel comprising:

a pair of sustaining discharge electrodes;

an address electrode facing said pair of sustaining discharge electrodes;

a discharge space disposed between said pair of sustaining discharge electrodes and said address electrode,

said discharge space being filled with a discharge-gas mixture containing at least Xe, Ne and He; and

a circuit for applying a voltage pulse to said address electrode and 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 from 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 said plasma display panel according to claim 1 , and a driving circuit including at least a control circuit, for driving said plasma display panel.

6 . An imaging device comprising said plasma display panel according to claim 2 , and a driving circuit including at least a control circuit, for driving said plasma display panel.

7 . An imaging device comprising said plasma display panel according to claim 3 , and a driving circuit including at least a control circuit, for driving said plasma display panel.

8 . An imaging device comprising said plasma display panel according to claim 4 , and a driving circuit including at least a control circuit, for driving said plasma display panel.

9 . 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.

10 . A plasma display panel according to claim 9 , wherein said Xe proportion of said discharge-gas mixture is in a range of 2% to 14%.

11 . A plasma display panel according to claim 9 , wherein said Xe proportion of said discharge-gas mixture is in a range of from 6% to 14%.

12 . A plasma display panel according to claim 9 , wherein said Xe proportion of said display-gas mixture is in a range of from 6% to 12%.

13 . An imaging device comprising a plasma display panel according to claim 9 , and a driving circuit including at least a control circuit, to drive said plasma display panel.

14 . An imaging device comprising a plasma display panel according to claim 10 , and a driving circuit including at least a control circuit, to drive said plasma display panel.

15 . An imaging device comprising a plasma display panel according to claim 11 , and a driving circuit including at least a control circuit, to drive said plasma display panel.

16 . An imaging device comprising a plasma display panel according to claim 12 , and a driving circuit including at least a control circuit, to drive said plasma display panel.
