Display device and method of driving a display panel

A display device comprising:

• a display panel including a plurality of pairs of row electrodes between which a capacitive load is formed, and a plurality of column electrodes arrayed in the direction intersecting with the row electrodes so as to form discharge cells at respective intersections of the row electrode pairs and the column electrodes;
• a driver circuit for supplying a sustain discharge pulse between a pair of row electrodes by performing a process having:
• under a state fixed one row electrode for each of the pairs of row electrodes at a first potential in a light emission sustain period of the display panel, a first step of gradually changing the potential of the other row electrode for each of the pairs of row electrodes from the first potential toward a second potential by means of resonance between the capacitive load and a first inductor;
• a second step of fixing the other row electrode in the pair of row electrodes at the second potential;
• and a third step of gradually changing the potential of the other row electrode of the pair of row electrodes from the second potential toward the first potential by means of resonance between the capacitive load and a second inductor;
• and
• a power limiting circuit for limiting power consumption of said driver circuit, in accordance with luminance information of an input image signal;
• wherein when the power consumption of the driver circuit is not limited by the power limiting circuit, the driver circuit performs the second step before the potential of the other row electrode of the pair of row electrodes reaches the second potential at the first step, while when the power consumption of the driver circuit is limited by the power limiting circuit, the driver circuit reduces the length of the period of the second step and performs the third step after completion of the reduced second step.
