Description
図10は、図8のPDPのY電極ラインに対する通常的なアドレスディスプレイ分離駆動方法を示している。図面を参照すれば、単位フレームは時分割階調表示を実現するために所定数、例えば8個のサブフィールドSF1、・・・、SF8に分割されうる。また、各サブフィールドSF1、・・・、SF8はリセット区間(図示せず)と、アドレス区間A1、・・・、A8及び、維持放電区間S1、・・・、S8に分割される。
図12は、大韓民国公開特許第2002−0002250号公報に開示された表示装置の構成を表すブロック図である。前記大韓民国公開特許第2002−0002250号公報は、アドレス区間で同じ位相の複数のデジタル信号が同じタイミングに遷移することに起因して多量の電磁波や磁界が発生して表示画面にノイズを発生するか、または他の機構や回路に影響を及ぼす問題点を解決するためのものである。このために前記公開特許は、複数のアドレス電極駆動回路それぞれにデジタルデータの位相を異にして送出することを特徴とする。
