Patent ID: 8502750

Claim:
A method for driving a plasma display panel, comprising: providing video input data to a brightness or contrast control module for respectively adjusting the gain or the offset of the video input data in said brightness or contrast control module in order to obtain adjusted video data in front of a power management module providing a number of sustain pulses applied to the plasma display panel, wherein said adjusted video data are applied to a compensating module for changing the level of said adjusted video data and are applied to an attenuation evaluation unit for calculating the attenuation of predetermined input video data tuned by the brightness or contrast control module to provide attenuation information representative of the attenuation provided by said brightness or contrast control module, to provide control signals to reduce the number of sustain pulses according to said tuning of predetermined input video data by the brightness or contrast control module and to increase the level of said adjusted video data according to the reduced number of sustain pulses for driving said plasma display panel with reduced power consumption and improved picture quality.
