Abstract
A display device in which a driver circuit supplies a sustain discharge pulse between a pair of row electrodes by performing a process having, under a state fixed one row electrode for each pair of row electrodes at a first potential in a light emission sustain period of a display panel, a first step of gradually changing the potential of the other row electrode for each pair of row electrodes from the first potential toward a second potential by means of resonance between a 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; 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 when power consumption is not limited; and reduces the length of the period of the second step and performs the third step after completion of the reduced second step when power consumption is limited.
