Abstract:
1. A display device that displays an image by causing a plurality of discharge cells to selectively discharge, comprising: a recovery unit that recovers charges stored in said discharge cells to drive a drive pulse by using the recovered charges; and a detector that detects a lighting rate of any of said plurality of discharge cells that are to be turned on at the same time, wherein said plurality of discharge cells include a capacitive load, and said recovery unit includes an inductor having at least one inductance element that has one end connected to said capacitive load, and a resonance driver that drives said drive pulse by LC resonance of said capacitive load and said inductance element, said display device further comprising a controller that controls said recovery unit so as to vary the entire period of the drive pulse, a recovery time in which said drive pulse is driven by said recovery unit, and a resonance time of said LC resonance, based on the lighting rate detected by said detector.
