Abstract: In a method of driving a panel, in initializing periods of a plurality of sub-fields constituting one field, one of all-cell initializing operation or selective initializing operation is performed. In the all-cell initializing operation, initializing discharge is performed in all the discharge cells for displaying an image. In the selective initializing operation, initializing discharge is selectively performed only in the discharge cells subjected to sustaining discharge in the sub-field immediately before the sub-filed. According to the average picture level (APL) of the signal of an image to be displayed or the light-emitting rate of a predetermined sub-field, the initializing operation in the initializing period of each sub-field is determined to be one of the all-cell initializing operation and the selective initializing operation.

Abstract: An object of the present invention is to provide a PDP driving circuit and a plasma display apparatus each of which controls a discharge current at the time of sustain discharge by carrying out a switching operation during a power source clamping while changing a turn-on time, so as to display an image whose brightness is suppressed without deteriorating the gray scale. A PDP driving circuit (701) for driving a PDP (10) is constructed by connecting in parallel at least two switching elements (S51, S52) whose turn-on times are different from each other such that the switching elements (S51, S52) can be controlled independently as switches for applying a predetermined potential to scan electrodes and sustain electrodes.

Abstract: A sub-field lighting rate measuring unit measures a lighting rate in a final sub-field. When the measured lighting rate exceeds a threshold value, a blank signal generator maintains a blank signal at a low level in a sustain time period in a sub-field. An output control circuit brings an output control signal into a low level on the basis of the blank signal. In this case, no data pulse is applied to an address electrode, so that there is no power consumed at the time of the rise and the fall of the data pulse.

Abstract: A reset pulse generating section applies the total of voltages of a positive voltage source and two constant-voltage sources from a high side ramp wave generating section to a high side scan switching device as the upper limit of a reset voltage pulse, and applies the ground potential from a low side ramp wave generating section to a low side scan switching device as the lower limit of the reset voltage pulse. A sustaining pulse generating section applies the upper and lower limits of a sustaining voltage pulse through a common sustaining pulse transmission path to the low side scan switching device.

Abstract: In a circuit driving a capacitive load Cp, current passed through a transistor Q3, a diode D1 and a recovering coil L is passed through lines L1, L2, and the inductance components of the lines L1 and L2, and the drain-source capacitances of the transistors Q1 and Q2 generate LC resonance. Capacitors C1 and C2 are connected in parallel to the drain-source regions of the transistors Q1 and Q2 to increase the total drain-source capacitance and reduce the resonance frequency, so that unwanted electromagnetic wave radiation in a frequency band affecting other electronic devices is suppressed.
