PLASMA DISPLAY DEVICE AND PLASMA DISPLAY PANEL DRIVING METHOD

摘要

Disclosed is a plasma display device that is equipped with a plasma display panel and an image signal-processing circuit (41) for the purpose of making display brightness uniform and improving image display quality. The image signal-processing circuit (41) comprises a loading correction unit (70) that is provided with a lit cell number-calculating unit (60) that calculates the number of discharge cells to be lit per display electrode pair and per subfield, a load-calculating unit (61) that calculates the load for each discharge cell based on the calculation results in the lit cell number-calculating unit (60), a correction gain-calculating unit (62) that calculates the correction gain for each discharge cell based on the calculation results in the load-calculating unit (61) and the discharge cell position, and a correcting unit (69) that subtracts from the input image signal the result of multiplying the output from the correction gain-calculating unit (62) with the input image signal, and outputs the same.
