Abstract
The driving method of the plasma display device has a plurality of combination sets for display that include a different number of combinations. Respective spatial differentiations of a red image signal, a green image signal, and a blue image signal are calculated. For an image signal of a large spatial differentiation, a combination set for display is used where the number of combinations is smaller than that in the combination set for display used for an image signal of a small spatial differentiation.
Claims4
A driving method of a plasma display device comprising:
- constituting one field period by a plurality of subfields having a predetermined luminance weight;
- selecting a plurality of combinations from arbitrary combinations of the subfields and creating a combination set for display;
- and
- controlling light emission or no light emission in a discharge cell and displaying gradation, using the combination of the subfields belonging to the combination set for display,
- wherein a plurality of combination sets for display having a different number of combinations is provided,
- wherein respective spatial differentiations of a red image signal, a green image signal, and a blue image signal are calculated, and
- wherein a combination set for display is used for an image signal of a large spatial differentiation, the number of combinations in the combination set for display being smaller than that in a combination set for display used for an image signal of a small spatial differentiation.
