Embodiment Construction

[0046] figure 2 It is an overall configuration diagram showing the plasma display device (PDP device) according to the first embodiment of the present invention. Reference numeral 10 denotes a three-electrode type plasma display panel (PDP: plasma display panel). In the PDP 10, a front substrate and a rear substrate are bonded together, and a discharge gas such as Ne-Xe is sealed therebetween. A plurality of sustain (X) electrodes and scan (Y) electrodes extending along the first (transverse) direction are alternately provided on the front substrate, and a dielectric layer is also provided to cover these electrodes. There are protective films such as MgO. On the rear substrate, a plurality of address electrodes extending in a second (longitudinal) direction perpendicular to the first direction are arranged, and a dielectric layer is provided to cover the electrodes. On the dielectric layer, partition walls are disposed corresponding to the address electrodes to distinguish...

Abstract

In a plasma display device including: a plasma display panel having scan electrodes, sustain electrodes, and address electrodes; scan electrode driving circuits; a sustain electrode driving circuit; and an address electrode driving circuit, each sub-field has a reset period, an address period in which scan pulses are sequentially applied to the scan electrodes, and address pulses are applied to the data electrodes in synchronization with the application to select cells to be turned on, and a sustain period in which the selected cells are turned on. An identical line detecting circuit for detecting display identical lines on which the turned-on cells on one line are identical in each sub-field is provided, and the scan electrode driving circuit simultaneously applies the scan pulses to a plurality of scan electrodes corresponding to the display identical lines in the address period.

Description

technical field [0001] The present invention relates to a driving method of a plasma display panel (PDP: plasma display panel) and a plasma display device (PDP device), and particularly relates to a technique for shortening the time required for an address operation of the PDP device. Background technique [0002] Plasma display devices (PDP devices) are being put into practical use as display devices, and among them, thin display devices with high luminance are highly expected. In the PDP device, since only the control of lighting or not lighting each unit is performed, when the gray scale (gradation) display is performed in the PDP device, a display frame is composed of a plurality of subfields. (frame), the sub-image fields lit in each of the units are combined for display. [0003] As far as the PDP device is concerned, it is divided into an address and display non-separation method and an address and display separation method. Wherein, the address and display non-separ...
