Abstract
High image display quality is achieved when a 3D image is displayed on a plasma display panel (10). For this purpose, a driver circuit includes sustain pulse generation circuits (60) and (80), control signal generation circuit (45) for generating a shutter opening/closing timing signal and a control signal for controlling sustain pulse generation circuits (60) and (80), all-cell light-emitting rate detecting circuit (46) for detecting the all-cell light-emitting rate in each subfield, and partial light-emitting rate detecting circuit (47) for detecting the partial light-emitting rate in each of a plurality of regions set in an image display region of plasma display panel (10) in each subfield. The driver circuit corrects the number of sustain pulses to be generated set based on the image signal and luminance weight in each of the subfields in response to the all-cell light-emitting rate and the partial light-emitting rate.
