Discharge Measurement of ac Plasma Display Panels using V-Q Lissajous' Figure

Abstract

(Mitsubishi Electric Corporation) We apply V-Q Lissajous' figure for the discharge measurements of ac PDPs (Plasma Display Panels) which have the electrodes covered with dielectric. From measuring the V-Q Lissajous' figure, we can know the wall voltage and the voltage between the discharge gap. We can also know the sparking voltage and extinction voltage. We compare the PDP discharge, which occurred at fast rise time applied voltage, and ozonizer discharge, which occurred at slow rise time applied voltage. Then we know that the discharge phenomena of PDPs, which sparking voltage is very high and extinction voltage is very small, is completely different from that of ozonizer discharge, which gap voltage is kept constant, the sustain voltage V*. From the point of view, we propose noble discharge model for ac-PDPs. ƒL •[ ƒ• •[ ƒh:ƒv ƒ‰ ƒY ƒ} ƒf ƒB ƒX ƒv ƒOE ƒC ƒp ƒl ƒ‹ •A-³ •º •ú "d •ALissajous 1•A ‚Í ‚ ¶ ‚ß ‚É •ð •¡ ‚Ì •î •ñ ‹@ Ší ‚Ì ‹} '¬ ‚È "-"W ‚â •A ‰AE 'ë ‚É ‚¨‚¯‚¨‚¯ ‚é ƒe ƒOE ƒr ‚Ì 'å OE^ ‰» ‚È ‚Ç ‚É "º ‚Á ‚Ä •A ƒf ƒB ƒX ƒv ƒOE ƒC ‚Ì 'å OE^ ‰» •A "-OE^ ‚É 'Î ‚· ‚é-v-] ‚ª ‹-‚Ü ‚Á ‚Ä ‚¢ ‚é •B "-OE^ ‚Ì 'å ‰ae-Ê ƒf ƒB ƒX ƒv ƒOE ƒC ‚AE ‚µ ‚Ä OE» •Ý"Á ‚É '•-Ú ‚ð •W ‚ß ‚Ä ‚¢ ‚é ‚Ì ‚ªPDP (Plasma Display Panel) ‚Å ‚ ‚é[1][2][3]•B PDP‚Ì "Á '· ‚Í 'å ‰ae-Ê ‰» ‚ª ‰Â "\ ‚È ‚± ‚AE •ACRT‚AE "ä Šr ‚µ ‚Ä "-OE^ ‚Å ‚ ‚é ‚± ‚AE •A ‰t •» ‚AE "ä Šr ‚µ ‚Ä Ž‹-ì Šp ‚ª •L ‚¢ ‚± ‚AE•A "™ ‚Å ‚ ‚é •B ‚± ‚Ì ‚½ ‚ß •A ‚¢ ‚í ‚ä ‚é •Ç Š| ‚¯ ƒe ƒOE ƒr ‚AE ‚µ ‚Ä OE¤ ‹ † ‚ª •i ‚ß ‚ç ‚ê ‚Ä ‚¢ ‚é •B "¯ Žž ‚É •‚ •¸ •× ‚Ì •î •ñ '[-p ‚Ì ƒf ƒB ƒX ƒv ƒOE ƒC ‚AE ‚µ ‚Ä ‚Ì-p "r "™ ‚à 'z 'è ‚³ ‚ê ‚Ä ‚¢ ‚é •B OE» •ó ‚ÌPDP‚Ì ‰ð OEˆ‰ÛOEˆ‰Û 'è ‚Í •A •‚ ‹P "x ‰» •A 'á •Á "ï "d-Í ‰» •A •‚ ƒR ƒ" ƒg ƒ‰ ƒX ƒg‰» •A "™ ‚Å ‚ ‚é •BPDP‚Í •ú "d ‚É ‚ae ‚é Ž ‡ ŠO •ü "-OEõ ‚ª OEu OEõ 'Ì ‚ð OEõ ‚ç ‚¹ ‚é •A ‚¢ ‚í ‚ä ‚é •ú "d "-OEõ 'f Žq ‚Å ‚ ‚é ‚½ ‚ß •A ‚± ‚Ì ‚ae ‚¤ ‚È-â 'è "_ ‚Ì ‰ð OEˆ•OEˆ•A "Á ‚É •‚ ‹P "x ‰» •A •‚ OEø-¦ ‰» ‚É ŠÖ ‚µ ‚Ä ‚Í •A •ú "d ‚Ì Šî 'b "I ‚È "Á •« ‚ð OEv 'ª •A ‰ð •Í ‚· ‚é ‚± ‚AE ‚ª •s ‰Â OE ‡ ‚Å ‚ ‚é •B ac-PDP‚Í-U "d 'Ì ‚ð ‰î ‚µ ‚Ä OEð-¬ •ú "d ‚³ ‚¹ ‚é •A ‚¢ ‚í ‚ä ‚éSD•ú "d(Silent Discharge)‚Å ‚ ‚è •A ƒI ƒ] ƒi ƒC ƒU •A 'Y Ž_ ƒK ƒX ƒOE•[ ƒU •A •½ " OEõ OE¹ ‚È ‚Ç ‚Ì •ú "d ‚AEŠî-{ "I ‚É "¯ ‚ ¶ ‚Å ‚ ‚é[4][5]•B ˆê "Ê ‚ÉSD •ú "d ‚Í •A •ú "d ‚ª-U "d 'Ì ‚ð ‰î ‚µ ‚Ä • ¶ ‚ ¶ ‚é ‚½ ‚ß •A •ú "d ƒM "à •" ‚Ì "d ˆ³ •Ï ‰» ‚ð '¼ •Ú ‚É 'ª 'è ‚· ‚é ‚± ‚AE ‚Í •¢ "ï ‚Å ‚ ‚é •B "Á ac-PDP‚Å ‚Í-U "d 'Ì •\-Ê ‚É '~ •Ï ‚³ ‚ê ‚½ •^ "d ‰× •A ‚¢ ‚í ‚ä ‚é ‰× ‚ª •ú "d ‚É •d-v ‚È-ð Š" ‚ð ‰Ê ‚½ ‚µ •A •ú "d ƒM ƒƒ ƒb ƒv "à ‚Ä ‚¢ ‚é "d ˆÊ •· ‚Í ŠO •" ‚Å 'ª 'è ‚³ ‚ê ‚é "d ˆÊ •· ‚AE'å ‚« ‚-ˆÙ ‚È ‚é • ‚± ‚Ì ‚ae ‚¤ ‚É •Aac-PDP‚Ì •ú "d ‚Ì OEv 'ª ‚ð •s ‚¤ •ã ‚Å •ú "d ƒM ƒv "à •" ‚Ì "d ˆ³ •Ï ‰» ‚ð ‰ð •Í ‚· ‚é ‚± ‚AE ‚Í ‹É ‚ß ‚Ä •d-v ‚Å ‚ ‚é ‚± ‚ê ‚Ü ‚Å ƒM ƒƒ ƒb ƒv ŠÔ ‚Ì "d ˆ³ ‚ð 'ª 'è ‚µ ‚½•ñ •• ‚Í ‹É ‚ß ‚Ä •-‚È ‚± ‚ê ‚Í •Ç "d ‰× ‚ð •³ Šm ‚É 'ª 'è ‚· ‚é ‚± ‚AE ‚ª •A 'Ê •í ‹É ‚ß ‚Ä •¢ " ‚ ‚é ‚½ ‚ß ‚Å ‚ ‚é •B •Ç "d ‰× ‚Ì 'ª 'è ‚É ŠÖ ‚µ ‚Ä ‚ÍWeber‚É ‚ae ‚é [6]‚ª‚ ‚é ‚ª •A •ú "d ‚Ì ƒ‚ ƒf ƒ‹ ‰» ‚Ì •l Ž@ ‚Ü ‚Å ‚É ‚Í ŽŠ ‚Á ‚Ä ‚¢ ‚È •]-ˆ ‚ÌSD•ú "d ‚Ì •ª-ì ‚Å ‚ÍV-Q Lissajous•}(V:"d ˆ³ •AQ "d ‰×)‚É ‚ae ‚Á ‚Ä •ú "d ‚ð ŠÏ 'ª ‚· ‚é •A ‚AE ‚¢ ‚¤ ‚± ‚AE ‚ª •s ‚í ‚ê ‚½[5]•BV-Q Lissajous•} ‚ð-p ‚¢ ‚½ OEv 'ª ‚Ì "Á '¥ ‚AE ‚µ ‚Ä •A •ú Š´"Š´"I ‚É-• ‰ð ‚Å ‚« ‚é •A •ú "d •" ‚AE "ñ •ú "d •" ‚ð-¾ Šm ‚É OE© ‚AE ‚ª ‚Å ‚« ‚é •A "ü-Í "d-Í ‚Ì 'ª 'è ‚ª-e ˆÕ ‚É ‚Å ‚« ‚é •A "™ ‚ª ‚ê ‚é •B ˆê •û •APDP‚Ì •ú "d ŠÏ 'ª ‚ÉV-Q Lissajous•} ‚ð-p ‚¢ ‚½ •ñ •• ‚ ‹Ž ‚É OE© ‚ç ‚ê ‚È ‚¢ •B ‚µ ‚© ‚µ•ã •q ‚Ì ‚ae ‚¤ ‚É •APDP‚Ì •ú "d ‚ "d ‚̈ê‚Ìˆê Ží ‚Å ‚ ‚è•A ‚± ‚Ì •ú "d ŠÏ 'ª ‚ÉV-Q Lissajous•} ‚Ì 'ª 'è ‚ð "-p ‚· ‚é ‚AE •A •]-ˆSD•ú "d ‚Å •s ‚í ‚ê ‚Ä ‚« ‚½ ‰ð •Í •û-@ ‚ð ‚ "d Šw˜_AŠw˜_A, 118Šª4• †,•½ •¬10"N 353
