摘要： In a plasma display apparatus with power consumption control, a control method is provided that eliminates unnaturalness of images during power control and that holds power consumption to within a target value regardless of the type of image pattern displayed. Differences between power consumption PSA and target value PSET are summed to calculate power consumption sum value PSUM, and if PSUM is negative, brightness set value MCBC is set to its maximum value MCBCMAX. If PSUM is positive, the value calculated by the equation "MCBCMAX - PSUM x MCBCMAX/PSUM,MAX" is set as the MCBC.

摘要： An address pulse width is reduced so that a display period for driving a plasma display panel (PDP) can be made longer. The PDP (10) comprises cells, each cell having first and second electrodes covered with dielectric and a third electrode (A's) covered with dielectric disposed in a direction crossing the first and second electrodes. A method of driving the PDP comprises addressing ones of the cells to be illuminated for displaying, by applying, between the second and third electrodes of the respective cells to be illuminated, a preparatory address pulse (Vap, Vyp) having a pulse width that produces no discharge, and by subsequently applying therebetween main address pulses, each main address pulse (Va, Vy) having a pulse width that produces discharge.

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 includes a plurality of electrodes (11, 12) formed on a substrate so as to extend in one direction. Between respective adjacent electrodes, discharge gaps (L 1 -L 5 ) for generating discharges or non-discharge gaps (NG 1 -NG 6 ) in which no discharge occurs are formed. The discharge gaps and the non-discharge gaps are alternately disposed. Electrodes of each electrode pair, between which one of the non-discharge gaps is formed, are electrically connected to each other. Each discharge gap is partitioned into a plurality of discharge cells (201, 202). The PDP constructed in the above-described manner 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.

摘要： An address pulse width is reduced, so that a display period for driving a plasma display panel (PDP) can be made longer. The PDP comprises cells, each cell having parallel first and second electrodes (X, Y) covered with dielectric and a third electrode disposed in a direction crossing the first and second electrodes (A). A method of driving the PDP comprises addressing ones of the cells to be illuminated for displaying. The addressing comprises effecting an operation of producing wall charges having the same polarity on the dielectric layers over the first and second electrodes before an operation of producing discharge between the second and third electrodes for addressing, so that the discharge for addressing occurs only between the second and third electrodes.
