OLED ni impfunyapfunyo ya Organic Light Emitting Diode, bivuze ngo "Organic Light Emitting display technology" mu Gishinwa. Igitekerezo ni uko urwego rusohora urumuri rushyizwe hagati ya electrode ebyiri. Iyo electron nziza kandi mbi zihuye mubintu kama, zirasohora urumuri. Imiterere shingiro yaOLED ni ugukora urwego rwibintu bitanga urumuri rwa nanometero icumi yuburebure ku kirahuri cya indium tin oxyde (ITO) nkurwego rutanga urumuri. Hejuru yumucyo utanga urumuri ni urwego rwa electrode yicyuma ikora imirimo mike, ikora imiterere nka sandwich.
tekinoroji yo hejuru OLED yerekana
Substrate (plastike ibonerana, ikirahure, file) - Substrate ikoreshwa mugushigikira OLED yose.
Anode (GUHINDUKA) - Anode ikuraho electron (yongera electron "umwobo") nkuko amashanyarazi agenda mubikoresho.
Gutwara umwobo - Iki gipimo kigizwe na molekile yibintu bitwara "umwobo" muri anode.
Luminescent layer - Uru rupapuro rugizwe na molekile yibintu kama (bitandukanye nuburyo bwo kuyobora) aho inzira ya luminescence ibera.
Gutwara ibikoresho bya elegitoronike - Iki cyiciro kigizwe na molekile yibintu bitwara electron muri cathode.
Cathodes (ishobora kuba iboneye cyangwa idasobanutse, bitewe n'ubwoko bwa OLED) - Iyo umuyaga unyuze mubikoresho, cathodes itera electron mumuzunguruko.
Inzira ya luminescence ya OLED mubusanzwe ifite ibyiciro bitanu bikurikira:
Injection Gutwara: munsi yumuriro wumuriro wamashanyarazi wo hanze, electron nu mwobo byinjizwa mumikorere mikorere kama yashyizwe hagati ya electrode ivuye muri cathode na anode.
Transport Ubwikorezi bwabatwara: electron zatewe inshinge ziva mumashanyarazi ya elegitoronike hamwe nu mwobo wo gutwara umwobo ujya kuri luminescent.
Rec Abatwara recombination: nyuma ya electron nu mwobo batewe mumurongo wa luminescent, bahujwe hamwe kugirango babeho umwobo wa elegitoronike, ni ukuvuga excitons, kubera ibikorwa byingufu za Coulomb.
Im Kwimuka kwa Exciton: Bitewe nubusumbane bwubwikorezi bwa electron nu mwobo, akarere nyamukuru gashinzwe gushimisha ubusanzwe ntabwo gatwikiriye luminescence yose, bityo kwimuka kwimuka bizabaho bitewe nubushakashatsi bwibanze.
Imirasire ya Exciton yangiza fotone: Inzibacyuho ya moteri ya exciton isohora fotone ikarekura ingufu.
