Abstract

An object of the present invention is to provide a high definition PDP screen without lowering the PDP luminescence efficiency. The display panel is provided with a plurality of cells that are arranged in a matrix, each of the plurality of cells emitting a different unique luminescent color; wherein a plurality of cells each bearing first luminescent color are disposed on every other line in a vertical direction, and a line of cells each having second luminescent color and a line of cells each having third luminescent color are alternated with a line of said plurality of cells having first luminescent color respectively therebetween.

Claims (18)

1. A display panel comprising a plurality of cells that are arranged in a matrix, each of the plurality of cells emitting a different unique luminescent color;

wherein a plurality of cells each bearing first luminescent color are disposed on every other line in a vertical direction, and a line of cells each having second luminescent color and a line of cells each having third luminescent color are alternated with a line of said plurality of cells having first luminescent color respectively therebetween.

2. A display panel comprising a plurality of cells that are arranged in a matrix, each of the plurality of cells emitting a different unique luminescent color;

wherein said plurality of cells having first luminescent color respectively are disposed on every other line in a vertical direction and a line on which cells having said second luminescent color and cells having said third luminescent color are disposed alternately between lines consisting of cells having said first luminescent color respectively.

3. The display panel according to claim 1 ;

wherein said display panel is a plasma display panel.

4. A scanning method used in a display panel comprising a plurality of cells that are arranged in a matrix, each of the plurality of cells emitting a different unique luminescent color;

wherein said scanning method uses an interlacing method to drive said display panel in which a plurality of cells each bearing first luminescent color are disposed on every other line in a vertical direction and a line of cells having second luminescent color and a line of cells having third luminescent color are disposed alternately with a line of cells having said first luminescent color therebetween;

wherein a plurality of lines, each consisting of cells having said first luminescent color, are divided into a first line group and a second line group so that lines of said first and second groups are alternated;

wherein scanning in a first field is done sequentially for a line consisting of cells having said first luminescent color, then its adjacent line consisting of cells having said second or third luminescent color in said first line group; and

wherein scanning in a second field is done sequentially for a line consisting of cells having said first luminescent color, then its adjacent line consisting of cells having said second or third luminescent color in said second line group.

5. A scanning method used in a display panel comprising a plurality of cells that are arranged in a matrix, each of the plurality of cells emitting a different unique luminescent color;

wherein said scanning method uses an interlacing method to drive said display panel in which a plurality of cells each bearing first luminescent color are disposed on every other line in a vertical direction and a plurality of cells having second luminescent color and a plurality of cells having third luminescent color are disposed alternately in a line between lines, each consisting of cells having said first luminescent color;

wherein a plurality of lines, each consisting of cells having said first luminescent color, are divided into a first line group and a second line group so that a line in said first line group and a line in said second line group are alternated;

wherein scanning in a first field is done sequentially for a line of cells having said first luminescent color, then its adjacent line on which cells having said second luminescent color and cells having said third luminescent color are disposed alternately in said first line group; and

wherein scanning in a second field is done sequentially for a line consisting of cells having said first luminescent color, then its adjacent line on which cells having said second luminescent color and cells having said third luminescent color are disposed alternately in said second line group.

6. The scanning method according to claim 4 ;

wherein said display panel is a plasma display panel.
