Abstract
A Plasma Display Panel (PDP) enabling optimization of a process to apply phosphor paste in order to achieve mass production using a jet nozzle method includes dummy areas structured to determine whether application conditions such as an ejecting pressure or the like are stable by measuring a depth of the applied layer after applying phosphor paste at a portion thereof in advance. The PDP includes: a first substrate and a second substrate opposing each other; address electrodes arranged on the first substrate; display electrodes arranged on the second substrate along a direction perpendicular to the address electrodes; barrier ribs arranged in a space between the first substrate and the second substrate to define a plurality of discharge cells, and phosphor layers arranged in each of the discharge cells.
Claims10
A method of manufacturing a plurality of plasma display panels on a single base plate, comprising the steps of:
- including for each plasma display panel, a plurality of discharge cells arranged between first and second substrates, phosphor layers arranged therein, and address electrodes and display electrodes corresponding to each discharge cell;
- arranging a plurality of nozzles above each of the discharge cells arranged between barrier ribs neighboring each other at an edge of the single base plate;
- moving the plurality of nozzles along a direction in which phosphor layers of the same color are to be applied to the discharge cells;
- stabilizing an amount of phosphor paste ejected by the nozzles within a non-display area of each plasma display panel, with the non-display area being arranged neighboring an edge of a display area of each plasma display panel;
- forming phosphor layers by ejecting a certain amount of the phosphor paste in one portion of the base plate corresponding to one of the plurality of plasma display panels and ceasing the ejecting of the phosphor paste in another portion thereof adjacent to the one portion;
- and
- firing the phosphor layers.
A method of manufacturing a plurality of plasma display panels on a single base plate, comprising the steps of:
- for each plasma display panel of the plurality of plasma display panels configured for fabrication on a single, common base plate, arranging barrier ribs in a space between first and second substrates to define a plurality of discharge cells between the first and second substrates, arranging phosphor layers in the space, and, in correspondence with each discharge cell, forming address electrodes on the first substrate and forming display electrodes transversely to the address electrodes;
- arranging a display area including a plurality of the discharge cells at a location where the address electrodes and the display electrodes cross each other;
- arranging a non-display area neighboring an edge of the display area along a direction perpendicular to a direction in which phosphor layers of the same color are applied to discharge cells neighboring each other;
- forming phosphor layers by ejecting a certain amount of phosphor paste in one portion of the base plate corresponding to one of the plurality of plasma display panels and ceasing the ejecting of phosphor paste in another portion thereof adjacent to the one portion;
- connecting the barrier ribs of the non-display area to the barrier ribs of the display area with orientations parallel to the direction in which the phosphor layers of the same color are applied;
- and
- firing the phosphor layers.
