PURPOSE: A line erase device and a method for PDP(plasma display panel) are provided to erase recorded lines in positions different each other per respective line after deciding a position in which sustain discharge per respective line is to be erased in a direction to compensate a brightness in accordance with the load of input video data, thereby decreasing the brightness difference between bit lines. CONSTITUTION: The line erase device for plasma display panel comprises a PDP controller(100), a bit corresponding erase position decider(210), an erase position generator(230), an electrode timing controller(250), a panel(300) and plural electrode drivers(350,370,390). The PDP controller(100) divides and loads externally input video data and then generates record, scan and sustain control signals. The bit corresponding erase position decider(210) receives and adds the video data from the controller(100) to calculate a mean value and then decides the erase position per a line of the bit in accordance with the mean value. The erase position generator(230) generate an erase position variable signal per respective bit line. |
