Abstract:
A driving apparatus for a plasma display panel having a plurality of discharge cells arranged in a matrix, wherein a unit display period for each of said discharge cells is divided into a light emitting period and a non-light emitting period in accordance with an input video signal for driving said plasma display panel, such that said discharge cells are driven to repeatedly emit light only during said light emitting period to provide a display at a half-tone luminance, said driver comprising:power consumption control means for obtaining a first electric power consumption value corresponding to light emissions by said input video signal and a second electric power consumption value representing electric power consumption by sustaining pulses that are applied without causing light emissions, based on an average luminance level of said input signal and the number of sustain pulses applied in said non-light emitting period, adding said first and second electric power consumption values to obtain an average power consumption, and controlling power consumption of said plasma display panel based on said average power consumption.
