Abstract
A plasma display panel having improved exhaust efficiency is disclosed. A plasma display panel according to a first embodiment of the invention includes first and second substrates opposing each other; barrier ribs that are located in a space between the first substrate and the second substrate for dividing a plurality of discharge cells in sealed spaces; display electrodes located along the discharge cells; and address electrodes formed in a direction intersecting the display electrodes. The barrier ribs include first barrier ribs having a first height and second barrier ribs having a second height so that the difference in height between the two ribs is provided.
Claims17
A plasma display device, comprising:
- a first substrate having a substantially planar surface;
- a second substrate opposing the first substrate;
- a plurality of barrier ribs that are located between the first substrate and the second substrate to partition a plurality of discharge cells, the plurality of barrier ribs comprising a first barrier rib and a second barrier rib;
- wherein the first barrier rib provides a first sidewall to a first one of the discharge cells, and the second barrier rib provides a second sidewall to the first discharge cell;
- wherein one or more additional barrier ribs provide the first discharge cell with one or more additional sidewalls, wherein each additional barrier rib has a height, which is the length thereof in a third direction, and wherein the height of each additional barrier rib is greater than the second height;
- wherein the first barrier rib extends generally in a first direction substantially parallel to the substantially planar surface and has a first height, which is the length of the first barrier rib in the third direction perpendicular to the substantially planar surface;
- wherein the second barrier rib extends generally in a second direction substantially parallel to the substantially planar surface and has a second height, which is the length of the second barrier rib in the third direction;
- and
- wherein the first height is greater than the second height.
A plasma display device, comprising:
- a first substrate having a substantially planar surface;
- a second substrate opposing the first substrate;
- a plurality of discharge cells arranged between the first and second substrates;
- a plurality of barrier ribs being located between the first substrate and the second substrate;
- wherein each discharge cell is defined by a plurality of sidewalls, a top wall generally facing the second substrate and a bottom wall generally facing the second substrate and opposing the top wall, wherein the plurality of barrier ribs provide at least three sidewalls that are interposed between the top and bottom walls;
- wherein each discharge cell has at least two holes in at least two sidewalls, and each hole comprises a clearance formed between the top wall and one of the sidewalls, and each hole connects to a neighboring discharge cell to allow fluid communication with the neighboring discharge cell;
- wherein a first discharge cell comprises a first sidewall provided by a first barrier rib and a second sidewall provided by a second barrier rib,
- wherein the first barrier rib has a first thickness and a first height, which is the length of the first barrier rib on a plane parallel to the substantially planar surface, the second barrier rib has a second thickness and a second height which is less than the first height, which is the length of the second barrier rib on the plane, and wherein the second thickness is greater than the first thickness;
- and
- wherein one or more additional barrier ribs provide the first discharge cell with one or more additional sidewalls, wherein each additional barrier rib has a height, which is the length thereof in a third direction, and wherein the height of each additional barrier rib is greater than the second height.
