Embodiment approach 1

[0052] figure 1 It is an exploded perspective view showing the configuration of panel 10 employed in the plasma display device according to Embodiment 1 of the present invention. On front substrate 21 made of glass, a plurality of display electrode pairs 24 composed of scan electrodes 22 and sustain electrodes 23 are formed. Furthermore, dielectric layer 25 is formed to cover scan electrodes 22 and sustain electrodes 23 , and protective layer 26 is formed on dielectric layer 25 .

[0053] The protective layer 26 has practical effect by being used as a panel material in order to reduce the discharge start voltage in the discharge cell. In the case of enclosing neon gas (Ne) and xenon gas (Xe) gas, the secondary electron emission coefficient is large and Made of magnesium oxide (MgO) with excellent durability as the main component.

[0193] Figure 7 It is a diagram schematically showing a driving voltage waveform applied to each electrode of panel 10 employed in the plasma display device according to Embodiment 2 of the present invention. exist Figure 7 In the figure below, scan electrode SC1 performing the address operation first in the address period, scan electrode SCn performing the address operation last in the address period, sustain electrode SU1 to sustain electrode SUn, and data electrode D1 to data electrode Dm are shown. Driving voltage waveform applied to each electrode.

[0194] in addition, Figure 7 The drive voltage waveform from subfield SF1 to subfield SF3 is shown in . In Embodiment 2, as in Embodiment 1, subfield SF1 is a subfield for performing a forced initialization operation, and subfield SF2 and subfield SF3 are subfields for performing a selective initialization operation. Therefore, in subfield SF1, subfield SF2, and subfield SF3, the waveform shape of the driving voltage a...

Abstract

Disclosed is a plasma display device which can be used as a three-dimensional image display device, wherein crosstalk is reduced for a user who is viewing a three-dimensional image displayed on a plasma display panel by means of shutter glasses, and write discharge is stably generated. Specifically, disclosed is a plasma display device which displays a three-dimensional image by alternately and repeatedly displaying a right-eye field and a left-eye field, wherein: each field is provided with a plurality of subfields having an initializing period, a writing period, and a sustain period in which a rising ramp waveform voltage is applied to a scanning electrode after all sustain pulses are generated; the luminance weight of each subfield is set in a manner such that the first subfield of each field has the smallest luminance weight, the second subfield has the largest luminance weight, and the luminance weight from the third subfield onwards becomes progressively smaller; and the rising ramp waveform voltage, which is applied to the scanning electrode during the sustain period of the subfield generated at the beginning of each field, is generated to have a more gradual gradient than the rising ramp waveform voltage, which is applied to the scanning electrode during the sustain period of the second subfield and onward.

Description

technical field [0001] The present invention relates to a driving method of a plasma display device, a plasma display device and a plasma display system for alternately displaying a right-eye image and a left-eye image stereoscopically viewable by shutter glasses on a plasma display panel. Background technique [0002] A typical AC surface discharge panel as a plasma display panel (hereinafter abbreviated as "panel") has a plurality of discharge cells formed between a front substrate and a rear substrate that are arranged to face each other. The front substrate forms a plurality of display electrode pairs parallel to each other on the glass substrate at the front side, and the display electrode pairs are composed of a pair of scan electrodes and sustain electrodes. Furthermore, a dielectric layer and a protective layer are formed to cover these display electrode pairs. [0003] In the rear substrate, a plurality of parallel data electrodes are formed on a rear glass substra...
