Staas & Halsey LLP
Plasma display device and processing method thereof
There is provided a plasma display device including: a nonlinear conversion circuit which nonlinearly converts a first image signal to a second image signal and expresses the second image signal by a real part and an error part to avoid use of a specific subfield lighting pattern; an error diffusion circuit which, when the error part of the second image signal is not zero, spatially or temporally diffuses the error part; and a subfield pattern conversion circuit which, when a lighting pattern of subfields is selected based on the error-diffused second image signal, selects another subfield lighting pattern without using the specific subfield lighting pattern.
