Problems solved by technology

[0006] On the contrary, in the ADS method, it is necessary to set a sustain period in a period other than the write period, so when the time required for the write period becomes longer due to the high-definition of the plasma display panel, etc., there is a problem that it cannot ensure the quality of the image display. The problem of the sufficient number of subfields for

Embodiment approach 1

[0080] [Structure of Plasma Display Panel 10]

[0081] figure 1 It is an exploded perspective view of plasma display panel 10 of 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 including scan electrodes 22 and sustain electrodes 23 are formed. Further, a dielectric layer 25 and a protective layer 26 are sequentially laminated on the front substrate 21 so as to cover the display electrode pairs 24 .

[0082]A plurality of data electrodes 32 are formed parallel to each other on rear substrate 31 . Further, on rear substrate 31 , dielectric layer 33 is formed so as to cover data electrodes 32 , and furthermore, lattice-shaped partition walls 34 are formed thereon. Then, phosphor layers 35 capable of emitting red, green, and blue light are provided in a space formed by the upper surface of dielectric layer 33 and the side surfaces of partition walls 34 .

Abstract

Disclosed are a plasma display panel driving method and a plasma display device. In the plasma display panel driving method, a plurality of display electrode pairs is divided into a plurality of display electrode pair groups, and one field is divided into a plurality of subfields. The length of a sustainment period and the length of an erase period are compared with each other. In the case where the sustainment period is longer than the erase period, a sustainment discharge and an erase discharge are performed for each display electrode pair group. In the case where the sustainment period is shorter than the erase period, the sustainment discharge and the erase discharge are performed in synchronization with each other among the display electrode pair groups. Further, in a subfield having the largest luminance weight or in a subfield having the largest light rate, the sustainment discharge and the erase discharge are performed in synchronization with each other among the display electrode pair groups.

Description

technical field [0001] The present invention relates to a driving method of a plasma display panel and a plasma display device using the same. Background technique [0002] In a typical AC surface discharge type panel that is a plasma display panel, a plurality of discharge cells are formed between a front substrate and a rear substrate that are arranged to face each other. [0003] Multiple pairs of display electrodes consisting of scan electrodes and sustain electrodes are formed parallel to each other on the front substrate, and multiple data electrodes are formed parallel to each other on the rear substrate. Then, the front substrate and the rear substrate are arranged and sealed in such a way that the display electrode pairs intersect the data electrodes three-dimensionally, and the discharge gas is sealed in the internal discharge space. Here, the discharge cells are formed at portions where the display electrode pairs face the data electrodes. [0004] As a method o...
