Plasma display panel
View Patent ↗A plasma display panel (PDP) is made of front panel ( 2 ) and rear panel ( 10 ). The front panel includes display electrodes ( 6 ), dielectric layer ( 8 ), and protective layer ( 8 ) that are formed on glass substrate ( 3 ). The rear panel includes address electrodes ( 12 ), barrier ribs ( 14 ), and phosphor layers ( 15 ) that are formed on rear glass substrate ( 11 ). The front panel and the rear panel are faced with each other, and the peripheries thereof are sealed to form discharge space ( 16 ) therebetween. Primary dielectric layer ( 13 ) is provided to cover address electrodes ( 12 ), and barrier ribs ( 14 ) are formed on primary dielectric layer ( 13 ). Primary dielectric layer ( 13 ) is made of dielectric glass containing at least bismuth oxide and having a softening point exceeding 550° C.
1. A plasma display panel (PDP) comprising:
a front panel including display electrodes, a dielectric layer, and a protective layer that are formed on a glass substrate; and
a rear panel including address electrodes, barrier ribs, and phosphor layers that are formed on a substrate, wherein the front panel and the rear panel are faced with each other, and peripheries thereof are sealed to form a discharge space therebetween,
wherein a primary dielectric layer is provided to cover the address electrodes;
the barrier ribs are formed on the primary dielectric layer;
the primary dielectric layer contains a glass component which includes 23 wt % to 50 wt % of bismuth oxide and 0.2 wt % to 1.0 wt % of at least either one selected from molybdenum oxide and tungsten oxide, and 1.5 wt % to 8.1 wt % of at least one selected from calcium oxide, strontium oxide, and barium oxide therein;
wherein the primary dielectric layer is composed of a dielectric glass having a softening point exceeding 550° C.; and
the address electrodes contain at least silver; and each of the address electrodes further contains a binding glass which includes 23 wt % to 50 wt % of bismuth oxide;
wherein the address electrodes are composed of a dielectric glass having a softening point exceeding 550° C.
2. The PDP of claim 1 , wherein
wherein the dielectric layer included in the front panel comprises first and second dielectric layers;
the first dielectric layer is in direct contact with the display electrodes and comprises a first proportion of bismuth oxide in a range of 20-40 wt %, and 0.1-7 wt % of at least one of molybdenum oxide, tungstic oxide, cerium dioxide, and manganese dioxide; and
the second dielectric layer is in direct contact with the first dielectric layer and comprises a second proportion of bismuth oxide, less than the first proportion of bismuth oxide, in a range of 11-40 wt %, and 0.1-7 wt % of at least one of molybdenum oxide, tungstic oxide, cerium dioxide, and manganese dioxide.
3. The PDP of claim 2 , wherein the display electrodes comprise silver.
4. The PDP of claim 2 , wherein
the second dielectric layer accounts for at least approximately 50% of the total thickness of the dielectric layer included in the front panel.
