Abstract:
1. A driving device of a plasma display panel comprising: a data-loading detection part for generating a first control signal and a second control signal in response to a data-loading of a sub-field; a direct current supply part for providing a direct current voltage, in response to the first control signal, to an address driving part; and an energy recovery circuit for providing a data signal in response to the second control signal to the address driving part, wherein the address driving part applies the direct current voltage to a data electrode line when a value of the data-loading is less than half of a maximum switching frequency of a data pulse applied to the data electrode line, and the address driving part applies the data signal to the data electrode line when the value of the data-loading is equal to or greater than half of the maximum switching frequency of the data pulse.
