Embodiment Construction

[0056] A plasma display panel suitable for the present invention has a structure in which two display electrodes (X electrode 5 and Y electrode 4) are placed opposite to each other across a discharge path formed by, for example, Figure 7B and 7C Partition walls 3 and 9 shown in are formed, and a narrow pulse discharge scheme is adopted as the discharge scheme in the plasma display panel. In the narrow pulse discharge scheme, a high-intensity electric field can be generated by forming a potential difference between each display electrode (Y electrode 4 and X electrode 5 ) and the metal partition 3 . The metal partition 3 generally functions as an anode because the applied voltage is 0 V, and each of the Y electrode 4 and the X electrode 5 functions as a cathode due to a negative voltage alternately applied thereto (when each negative voltage is applied to it, the Y electrode 4 and the X electrode 5 are used as anodes), so a discharge occurs between the display electrode to wh...

Abstract

The present invention provides a driving method which enables an improvement in emission efficiency and achievement of a higher degree of brightness when employing the address while display driving scheme. The essence of the present invention is as follows: Taking the 3-bit 8-gradation display as an example, a first H period (one horizontal scan period) of each of subfields is divided into 3 regions (first region, second region, and third region in the order of time), and, in each of the lines, an address period (address pulse PA and scan pulse PAY) of the subfield SF1 is set in its first region, an address period of subfield SF2 is set in its second region, and an address period of the subfield SF3 is set in its third region. The regions other than those in which the address period is set are used as the sustain period, and a time length of each of sustain pulses PS is set to 1 / 3 of the length of the H period. A reset period achieved by a reset pulse PR and a priming period achieved by a priming pulse PP are set in the region where the address period is set.

Description

technical field [0001] The present invention relates to a method for driving a plasma display panel for grayscale display, and more particularly to a method for driving a plasma display panel using an Address Simultaneous Display Drive (AWD) scheme. Background technique [0002] So far it has been proposed to have Figures 7A-7C A plasma display panel of the structure shown in. Figure 7A and 7C Each is a cross-sectional view of a part of a plasma display panel showing a unit, wherein a transparent front substrate 1, a rear substrate 2, partition walls 3, Y electrodes 4, X electrodes 5, address electrodes 6, phosphors 7, and discharge space8. [0003] Such as Figures 7A-7C As shown, each plasma display panel has a structure in which a front substrate 1 and a rear substrate 2 are integrally coupled with a partition wall 3 sandwiched therebetween, and a discharge space 8 is defined by the partition wall 3 between the front substrate 1 and the rear substrate 2 . in having ...
