Abstract
A plasma display panel includes first display electrodes and second display electrodes positioned inside barriers while opposing each other. A front panel has closed-type barriers to increase fluorescent substance application area. A rear panel has stripe-type barriers to lower address voltage between the first display electrodes and address electrodes and improve emission efficiency by means of long-gap discharge. The plasma display panel uses trigger discharge during address discharge and sustain discharge to lower discharge voltage.
Claims20
A plasma display panel comprising:
- a first substrate;
- a second substrate opposing the first substrate;
- a rear barrier layer on the first substrate between the first substrate and the second substrate and having first barriers extending in a first direction and being substantially parallel to one another, the rear barrier layer delimiting a plurality of discharge cells;
- a first fluorescent substance layer inside discharge cells of the plurality of discharge cells delimited by the rear barrier layer;
- a plurality of address electrodes positioned between the first fluorescent substance layer and the first substrate and being substantially parallel to the first barriers;
- a front barrier layer between the second substrate and the rear barrier layer and delimiting the plurality of discharge cells together with the rear barrier layer;
- and
- first display electrodes and second display electrodes alternating with each other inside the front barrier layer and extending in a second direction crossing the first direction,
- wherein the front barrier layer comprises second barriers formed in a shape corresponding to a shape of the rear barrier layer and being substantially parallel to one another and closed third barriers between the second barriers and the rear barrier layer, the first display electrodes and the second display electrodes being inside the closed third barriers, and
- wherein the closed third barriers have a second fluorescent substance on a surface thereof.
