Plasma display panel device
View Patent ↗A plasma display panel device is provided which is capable of obtaining a uniform state of light emission for displaying and of reducing electromagnetic radiation while easily achieving a high-definition image display. The plasma display panel device includes a pair of row electrodes made up of a scanning electrode and a common electrode (sustaining electrode) which provides one display row and formed in parallel with a face of a front substrate (scanning substrate) facing a rear substrate wherein a folding-back electrode is formed on a common electrode.
1. A plasma display panel device comprising:
a front substrate and a rear substrate between which a discharging gas space is formed;
a display row in parallel with a face of said front substrate facing said rear substrate comprising a pair of row electrodes made up of a scanning electrode and a common electrode; and
a folding-back electrode formed on either of said scanning electrode or said common electrode for every one display row such that a direction of a current flowing through said folding-back electrode and a direction of a current flowing through either of said scanning electrode or said common electrode are substantially opposite to each other,
wherein said folding-back electrode is not a row electrode.
2. The plasma display panel device according to claim 1 , wherein said folding-back electrode is disposed such that a magnetic flux produced by a current flowing through said folding-back electrode and a magnetic flux produced by a current flowing through either of said scanning electrode or said common electrode substantially cancel each other out.
3. The plasma display panel device according to claim 1 , wherein a bus electrode is connected to said common electrode.
4. The plasma display panel device according to claim 3 , wherein an auxiliary folding-back electrode is formed on said bus electrode.
5. The plasma display panel device according to claim 1 , wherein each of driving terminals for said scanning electrode and common electrode is formed in every one display row.
6. A plasma display panel device comprising:
a front substrate and a rear substrate between which a discharging gas space is formed;
a pair of row electrodes made up of a scanning electrode and a common electrode which provide one display row in parallel with a face of said front substrate facing said rear substrate; and
a folding-back electrode formed on either of said scanning electrode or said common electrode for alternating sequence of display row such that a direction of a current flowing through said folding-back electrode and a direction of a current flowing through either of said scanning electrode or said common electrode are substantially opposite to each other,
wherein said folding back electrode is not a row electrode.
7. The plasma display panel device according to claim 6 , wherein said folding-back electrode is disposed such that a magnetic flux produced by a current flowing through said folding-back electrode and a magnetic flux produced by a current flowing through either of said scanning electrode or said common electrode substantially cancel each other out.
8. The plasma display panel device according to claim 6 , wherein a dummy electrode is formed between display rows in which said folding-back electrode is not formed.
9. The plasma display panel device according to claim 6 , wherein each of driving terminals for said scanning electrode and common electrode is formed in alternating sequence of display rows.
