Problems solved by technology

In this way, the design for heat dissipation in the large Miller integrating circuit that consumes power is also difficult
[0018] In addition, in a plasma display device using a high-definition large-screen panel, since the power consumption when driving the panel increases, the power consumption when generating the ramp waveform voltage also relatively increases, and the design for heat dissipation becomes more difficult.

Embodiment approach 1

[0053] figure 1 It is an exploded perspective view showing the structure of panel 10 used in the plasma display device in Embodiment 1 of the present invention.

[0054] On front substrate 11 made of glass, a plurality of display electrode pairs 14 including scan electrodes 12 and sustain electrodes 13 are formed. Furthermore, dielectric layer 15 is formed to cover scan electrodes 12 and sustain electrodes 13 , and protective layer 16 is formed on dielectric layer 15 .

[0055] In order to reduce the discharge start voltage in the discharge cell, this protective layer 16 is actually used as a panel material, and when neon (Ne) and xenon (Xe) gases are enclosed, the secondary electron emission coefficient is large and the durability is excellent. Magnesium oxide (MgO) is formed as a main component material.

Abstract

Even in a high-definition and large-screen plasma display panel, the increase of power consumption is suppressed and a stable discharge is generated. The plasma display panel comprises a plurality of discharge cells each having a display electrode pair consisting of a scan electrode and a sustain electrode and a data electrode. A plasma display panel driving method is a method for driving the plasma display panel in which one field consists of a plurality of sub-fields each having an initialization period during which a falling ramp waveform voltage dropping to a predetermined negative voltage is applied to the scan electrode, a write period, and a sustain period. In the plasma display panel driving method, during the initialization period, the scan electrode is brought into a high impedance state before the falling ramp waveform voltage is applied to the scan electrode and a voltage waveform changing from a high voltage level to a low voltage level is applied to the sustain electrode, thereby lowering the voltage level of the scan electrode and setting the voltage level after being lowered as the start voltage of the falling ramp waveform voltage.
