摘要:
A plasma display apparatus and a method of driving the same are disclosed. The method includes assigning a predetermined number of sustain signals to each of subfields constituting a frame depending on weight values of the subfields, selecting some of combinations of the subfields, actually measuring a luminance of light emitted by the plasma display apparatus during a frame comprised of the selected subfield combination, normalizing a luminance corresponding to each subfield combination depending on the actually measured highest luminance to calculate a reference normalized gray level, and calculating an intermediate gray level between the reference normalized gray levels.
