Abstract: A method for driving a PDP having a first electrode, a second electrode, and a panel capacitor formed therebetween. The method includes a reset period, an address period, and a sustain discharging period. In the reset period, a first voltage waveform falling from a first voltage to a second voltage is applied to the first electrode for a first period. Wall charges formed in the sustain discharging period are erased. A second voltage waveform rising from a third voltage to a fourth voltage is applied to the first electrode for a second period. A third voltage waveform falling from a fifth voltage to a sixth voltage which is lower than the second voltage is applied to the first electrode for a third period.

Abstract: An improved plasma display panel (PDP) having decreased background brightness, decreased power consumption, and improved contrast is disclosed. In one embodiment, the PDP includes a driver that includes an address electrode, and a scan electrode and a sustain electrode are arranged in pairs with the address electrode. The PDP driver also includes a subfield data generator that generates subfield data from input image data. An address data driver is provided for applying to the address electrode a voltage that corresponds to the subfield data. An address data determiner included in the PDP driver detects a subfield which has no address data from among the subfield data, and outputs a control signal that controls a reset operation the detected subfield is driven. In response, a scan/sustain pulse driver applies to the scan electrode and the sustain electrode a voltage that corresponds to the control signal provided by the address data determiner.

Abstract: A plasma display panel (PDP) driving method and a PDP gray-representing method for improving representation performance of low gray scales is disclosed. A voltage rising from a low level voltage to a reset voltage of a reset period of a subsequent subfield is applied to a scan electrode, without having a sustain period, after performing an address operation of the subfield with the minimum weight. The discharge cell selected in the address period of the minimum weight is discharged in an initial part of the gradually rising voltage.

Abstract: Disclosed is a driving device of a PDP having a misfiring erase period between reset and address periods. Large amounts of positive and negative charges are respectively formed on scan and sustain electrodes because of an unstable reset operation in the reset period. Because of the charges, discharging can occur between the scan and sustain electrodes in the sustain period even without addressing in the address period. In the misfiring erase period, a voltage is applied between the scan and sustain electrodes to generate discharging and respectively form negative and positive charges on the scan and sustain electrodes. An erase pulse is then applied to erase the negative and positive charges respectively formed on the scan and sustain electrodes.

Abstract: An improved plasma display panel and a method for driving the same are disclosed. Illustratively, the plasma display panel includes a plurality of address electrodes and a plurality of scan electrodes and sustain electrodes, and displays video data through dual scanning. A temperature sensor included in the plasma display panel detects a temperature of the plasma display panel. When the detected temperature is determined to be low, a scanning direction in which a voltage is applied to the scan electrodes is controlled such that the plasma panel is scanned from both ends to the center. When the detected temperature is determined to be high, a scanning direction in which a voltage is applied to the scan electrodes is controlled such that the plasma panel is scanned from a top towards the center. Altering the scan direction based on temperature improves picture quality.

Abstract: A method and apparatus for driving a plasma display panel (PDP) by which reset stabilization can be achieved are provided. In the method for driving a PDP, successive field periods, each including a reset period for initializing the state of respective cells, an address period for selectively discriminating cells to be turned on from cells not to be turned on and for performing an addressing operation, and a sustain period for discharging the addressed cells are performed. A reset stabilization period for inducing discharging in a discharge space between cells is additionally performed before the reset period if a rest period having a predetermined time duration is present between the sustain period of a preceding field and the reset period of the field. Therefore, the reset operation can be performed in a state where discharge cells between electrodes are sufficiently primed.

Abstract: A method and an apparatus for driving an image display device, such as, a plasma display panel, to represent a gradation. The pixels of a panel are classified into a plurality of groups, and one frame period is divided with time into n subfields. An address period and a sustain period are sequentially executed on each of the groups during at least two of the n subfields. While the pixels of one group are undergoing an address period during a subfield, the pixels of the other groups remain idle. While the pixels of one group are undergoing a sustain period, the pixels of groups that have already been addressed also undergo the sustain period. During one subfield, different gradation weights are allocated to the groups. A gradation of visual brightness for each pixel is determined by performing an address period for either all or some of the groups during at least two subfields. The panel driving method for representing gradation is adaptable.

Abstract: A method for driving a plasma display panel includes applying an erasing pulse, a reset pulse and a scan pulse respectively in each of an erasing period, a reset period and a scan period. In a reset period, a reset pulse with a waveform of a sloped ramp pulse is applied to the scan electrode. The sloped ramp pulse induces a discharge between the scan electrode and the address electrode in the middle of the period while the pulse voltage increases. This prevents extremely high discharges between the scan electrode and the address electrode and improves the contrast of the display. An apparatus that implements such method is also disclosed.

Abstract: A method and apparatus for driving a plasma display panel in which a reset discharge is selectively performed with regard to the distribution of wall charges in discharge cells are provided. The method includes applying a reset signal for preventing a reset discharge from occurring in cells having conditions under which an address discharge can occur during the address period and allowing a reset discharge occur in cells which do not have the above conditions. Accordingly, an unnecessary discharge can be suppressed, thereby making a dark portion darker. Therefore, contrast can be greatly improved, and a time for a reset period can be reduced.
