Abstract:
A method of driving a plasma display panel, comprising:replacing a frame with three or more subframes having luminance weights; setting light emission of cells on or off for each of the subframes so as to realize a gradation display; providing a drive halt period after a final subframe period in a frame in which a sum of subframe periods that are allocated to the subframes is shorter than a frame period, when a temperature of a panel surface is not more than a preset temperature, the drive halt period having a length corresponding to a difference between the frame period and the sum of the subframe periods; providing a plurality of drive halt periods having length weights corresponding to a luminance weight arrangement in a frame in which the sum of the subframe periods is shorter than the frame period, when the temperature of the panel surface exceeds the preset temperature; and allocating a free time that is the difference between the frame period and the sum of the subframe periods to the plurality of drive halt periods in accordance with the length weights thereof.
