Abstract:
1. 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 of the subfields to create at least a first coding table and a second coding table for display, each of the first coding table and the second coding table have a different number of combinations; and controlling light emission or no light emission in a discharge cell and displaying gradation, using the first coding table and the second coding table for display, wherein respective signal levels of a red image signal, a green image signal, and a blue image signal are compared with each other, and, wherein the first coding table is selected for an image signal of a color that has a relatively low signal level lower than a first threshold, the second coding table is selected for an image signal of a color that has a relatively high signal level higher than a second threshold, the number of combinations in the first coding table being smaller than the number of combinations in the second coding table.
