摘要： An initialization and driving method for a plasma display panel. When the plasma display panel is turned on, a voltage at a first electrode is increased from a first voltage to a second voltage, and a voltage at a second electrode is reduced from a fourth voltage to the fifth voltage for the purpose of forming wall charges in cells while a third voltage is applied to the second electrode. A voltage is applied to the first electrode and the second electrode to establish a difference between the first electrode and the second electrode to be alternately a sixth voltage and a negative voltage of the sixth voltage, and therefore the cell is discharged.

摘要： In a plasma display, image data are mapped on N subfields, and the subfield with the greatest weight is determined from among the mapped subfields. When the subfield with the greatest weight is the Kth subfield (K>M), grayscales of the image data are expressed with the mapped data of the (K−M+1)th subfield to the Kth subfield, and the mapped data from the first subfield to the (K−M)th subfield may be ignored.

摘要： In a driving circuit of a plasma display, a drain of a first transistor is coupled to a scan electrode and a switch driver is coupled between a gate and a source of the first transistor. The switch driver turns on the first transistor to reduce voltage of the scan electrode and charge a capacitor coupled to the source of the first transistor. When voltage across the capacitor is increased by a predetermined voltage, the first transistor is turned off and the scan electrode is floated. By repeating this operation, voltage of the scan electrode is gradually reduced. When a discharge is generated in a discharge cell of the plasma display by decreasing voltage of the scan electrode, voltage of the floated scan electrode is increased. The switch driver further discharges the capacitor when voltage variance of the floated scan electrode increases.

摘要： A power recovery circuit for a plasma display device and a driving method for the circuit. An inductor is coupled to form a resonance circuit and to generate a voltage difference between two electrodes of the same type that are coupled to the two terminals of a power recovery circuit. The resulting circuit allows formation of resonance between the two electrodes and power recovery from the panel capacitors formed in a PDP. Instead of hard-switching, the power recovery circuit is also used to maintain the voltage difference at the pre power recovery level after recovering power. As a result, power consumption is reduced when changing the voltage level of the two electrodes from the same voltage level to different voltage levels and vice versa. Further, elements having the same function are combined into a single element to simplify the circuit.

摘要： A plasma display panel. Delay circuits are added to a control terminal of a switch and a rising delay time is established to be different from a falling delay time in an address driving circuit so that voltages at adjacent address electrode may not be concurrently changed in the opposite directions. Accordingly, power consumption by the address driving circuit is minimized without a power recovery circuit.

摘要： A plasma display panel driving method and apparatus. In a falling period of a reset period, a voltage at a scan electrode is gradually reduced to the voltage Vnf from the voltage Vs while a sustain electrode is maintained at the voltage Va. In an address period, the voltage Va is applied to an address electrode of a discharge cell to be turned on while the sustain electrode is maintained at the voltage Va. Therefore, the number of voltage sources can be reduced by establishing the voltage applied to the sustain electrode to correspond to the voltage Va in the falling period of the reset period and in the address period.

摘要： A plasma display supplies a high level voltage and a low level voltage to first and second electrodes performing a sustain discharge in opposite phases during a sustain period. After a voltage of the first electrodes is decreased through a first inductor connected to the first electrodes, the first electrodes are floated to maintain the voltage of the first electrodes at a second voltage. Then, while the voltage of the first electrodes is changed from the second voltage to a low level voltage, the magnitude of the current flowing through a second inductor connected to the second electrodes is increased. Then, the voltage of the second electrodes is increased to a high level voltage using the second inductor. After energy is accumulated in the second inductor, the voltage of the second electrode is increased to the high level voltage.
