Problems solved by technology

[0008] However, according to the method described in Patent Document 3, although the degree to which the afterimage is recognized is alleviated to some extent, the afterimage phenomenon itself is not reduced.
In addition, since image processing such as moving the display position of the image is used at the same time, there is a possibility that the image cannot be displayed faithfully.

Embodiment approach 1

[0052] figure 1 It is an exploded perspective view showing the structure of the panel 10 according to Embodiment 1 of the present invention. On front substrate 21 made of glass, a plurality of display electrode pairs 24 including scan electrodes 22 and sustain electrodes 23 are formed. Then, a dielectric layer 25 is formed so as to cover the display electrode pairs 24 , and a protective layer 26 is formed on the dielectric layer 25 . A plurality of data electrodes 32 are formed on rear substrate 31 , dielectric layer 33 is formed so as to cover data electrodes 32 , and grid-shaped partition walls 34 are formed thereon. Then, fluorescent material layers 35 that emit light in red, green, and blue colors are provided on the side surfaces of the barrier ribs 34 and the dielectric layer 33 .

[0053] These front substrate 21 and rear substrate 31 are separated by a small discharge space so that display electrode pairs 24 and data electrodes 32 are arranged to face each other, and...

Embodiment approach 2

[0119] Embodiment 2 differs from Embodiment 1 in that a predetermined number of sustain pulses from the end of the sustain period are used as sustain pulses rising slowly.

[0120] Figure 9 It is a diagram showing an example of sustain pulses applied to scan electrodes SC1 to SCn and sustain electrodes SU1 to SUn in the sustain period in Embodiment 2 of the present invention. Figure 9 Sustain pulses when the number of sustain pulses in the sustain period of one subfield is "2" to "30" are shown, and the first sustain pulse A is described as "A", and the second sustain pulse B is described as "B". Additionally, the Figure 5A The pulse with a long pulse duration described as "the first sustain pulse" or "the second sustain pulse" is used as the first sustain pulse and the second sustain pulse of the sustain period, and is described as "X", and will be counted from the last A predetermined number of sustain pulses are described as "Y". The sustain pulse Y may have the same ...

Abstract

Provided is a method for driving a panel formed by a plurality of discharge cells each having a scan electrode and a sustain electrode. Each one field is formed by a plurality of subfields having a write period for generating write discharge by a discharge cell and a sustain period for generating sustain discharge by a discharge cell in which write discharge is generated by applying a sustain pulse alternately to a scan electrode and a sustain electrode. The sustain pulse has a first sustain pulse having a gentle rise and a second sustain pulse having a steep rise as compared to the first sustain pulse. At least one of the second sustain pulse and the third sustain pulse applied to the scan electrode is the second sustain pulse. At least one of the second sustain pulse and the third sustain pulse applied to the sustain electrode is the second sustain pulse.

Description

technical field [0001] The invention relates to a driving method for a plasma display panel used in a wall-mounted TV or a large monitor. Background technique [0002] In a typical AC surface discharge panel as a plasma display panel (hereinafter abbreviated as "panel"), a plurality of discharge cells are formed between opposing front and rear panels. [0003] In the front panel, a plurality of display electrode pairs consisting of scan electrodes and sustain electrodes are formed parallel to each other on the front glass substrate, and in the back panel, a plurality of data electrodes are formed in parallel on the rear glass substrate. Then, the front panel and the back panel are sealed after facing each other so that the display electrode pairs and the data electrodes intersect three-dimensionally, and discharge gas is enclosed in the internal discharge space. Here, a discharge cell is formed in a portion where the display electrode pair and the data electrode are opposed...
