摘要： A method for detecting noise includes determining whether a data value of a candidate pixel in a predetermined region of an image matches a first dynamic false contour (DFC) candidate value, determining whether a data value of at least one pixel adjacent to the candidate pixel matches a second DFC candidate value, and changing the data value of the candidate pixel the prior two determinations. The data value of the candidate pixel may be changed to a value in a lookup table. The first and second DFC candidate values may also be stored in one or more lookup tables.

摘要： A stable address operation is performed also when a plasma display panel having a high definition and large screen is driven. For this purpose, a driving method of a plasma display panel is provided. The panel is driven by forming one field using a plurality of subfields each of which has an address period and a sustain period in which sustain pulses varying from a base potential to a voltage at which a sustain discharge is caused in the discharge cell having undergone the address discharge are applied to the display electrode pairs. In the driving method, after generation of the final sustain pulse in the sustain period, an up-ramp waveform voltage which increases from the base potential to a predetermined voltage is applied to the scan electrodes. The predetermined voltage is set lower than the voltage of the sustain pulses.

摘要： A driving method includes generating an address discharge in selected cells out of discharge cells and setting the selected cells to either an emission enable state or a non-emission state in an address period which is set in each subfield period. The driving method also includes generating sustaining discharge in discharge cells being set to the emission enable state by applying at least one discharge sustaining pulse P+ between a scanning electrode and a common electrode constituting each row electrode pair, in a discharge sustaining period following the address period. The driving method also includes decreasing the applied voltage between the scanning electrode and common electrode in steps when a final applied pulse P+ out of the discharge sustaining pulses falls.

摘要： A two-phase driving operation is performed by a first circuit and a second circuit in at least one sub-field. The first circuit applies a first ramp waveform that drops from a first potential to a second potential to a plurality of first scan electrodes in a setup period, and sequentially applies a scan pulse to the plurality of first scan electrodes in a write period. The second circuit applies a second ramp waveform that drops from the first potential to a third potential that is higher than the second potential to a plurality of second scan electrodes, and then raises the plurality of second scan electrodes to a fourth potential in the setup period, and holds the plurality of second scan electrodes at a fifth potential that is higher than the third potential and lower than the fourth potential in a period where the first scan pulse is applied, and then sequentially applies a scan pulse to the plurality of second electrodes in the write period. Discharge failures during write discharges can be prevented from occurring by employing the two-phase driving operation.

摘要： An interlace-type PDP is driven by an improved driving method so as to achieve a greater operating margin, higher resolution, and higher brightness. The interlace-type PDP is driven using odd and even frames in such a manner that the cells are grouped into cell groups such that each cell group includes two or three cells which are adjacent in a direction crossing the electrode pairs, and the cells are driven in units of cell groups. The grouping of cells is performed differently for even and odd frames such that, in one type of frame, locations of two or three cells grouped into each group are shifted by one cell, in the direction crossing the electrode pairs, from the locations of cells grouped together in the other type of frame.
