Embodiment Construction

[0050] Below, will refer to Figure 5 Referring to FIG. 8, the plasma display driving method and device embodiment of the present invention will be described in detail.

[0051] refer to Figure 5 It can be seen that the PDP driving method according to the embodiment of the present invention has the following characteristics: one frame time period is divided into selective writing subfields ( WSF) and a selective erase subfield (ESF) including the 3rd to 12th subfields (SF3 to SF12), and drives the PDP in this way.

[0052] The first subfield (SF1) includes the following time periods: a restart period for uniformly distributing a certain amount of wall charge on the unit body of the entire screen; using write discharge to select and open the unit body (on-cell) The write addressing period; the sustaining period for generating sustain discharge in the selected open cell body; and the erasing period for erasing the wall charge remaining in the cell body through the sustaining ...

Abstract

The invention relates to a plasma display driving method and apparatus. The plasma display has a plurality of scanning electrodes, a plurality of maintaining electrodes and a plurality of addressing electrodes. It is divided driving mode of rerun time section, addressing time section and maintaining time section by one rim time section. It provides the scanning voltage to the scanning electrode on addressing period and provides data voltage to the scanning electrode and chooses unit body, then it provides dc biased voltage to the maintaining electrode, reduces the voltage of the scanning electrode between addressing time section and maintaining time section, keeps the voltage of the maintaining electrode on dc biased voltage level and in turn provides the maintaining pulse to the scanning electrode and the maintaining electrode.

Description

(1) Technical field [0001] The invention relates to the technology of the plasma display, in particular to a driving method and device of the plasma display capable of generating stable discharge while reducing the addressing time. (2) Background technology [0002] Plasma display (Plasma display Panel, hereinafter referred to as "PDP") is to use the 147nm ultraviolet rays emitted by He+Xe or Ne+Xe gas discharge to make phosphors emit light, and display pictures and moving images including text and pictures . This plasma display (PDP) can not only become ultra-thin and large-scale easily. And, thanks to recent technological developments, it can also dramatically improve picture quality. In particular, the three-electrode AC surface discharge type plasma display (PDP) uses the wall charges accumulated on the surface to reduce the voltage required for discharge during discharge. Because it protects the electrodes from the lasing generated by the discharge, it has the advant...
