OLED shi ne gajarta ta Organic Light Emitting Diode, wanda ke nufin "Fasahar nunin haske na Organic Light Emitting" a cikin Sinanci. Ma'anar ita ce, an yi sandwiched Layer na haske mai fitar da haske tsakanin nau'in lantarki guda biyu. Lokacin da electrons masu kyau da korau suka hadu a cikin kwayoyin halitta, suna fitar da haske.OLED shine a yi wani Layer na kayan da ke fitar da haske na dubun nanometers mai kauri akan gilashin indium tin oxide (ITO) a matsayin mai haske mai haske. Sama da hasken haske shine Layer na electrodes na karfe tare da ƙananan aikin aiki, samar da tsari kamar sanwici.
babban fasahar OLED nuni
Substrate (m filastik, gilashi, tsare) - Ana amfani da substrate don tallafawa duka OLED.
Anode (TRANSPARENT) - Aanode yana kawar da electrons (ƙara "ramukan lantarki") yayin da halin yanzu ke gudana ta cikin na'urar.
Ramin jigilar ramuka - Wannan Layer yana kunshe da kwayoyin halitta na kwayoyin halitta waɗanda ke jigilar "ramuka" daga anode.
Luminescent Layer - Wannan Layer an yi shi ne da kwayoyin halitta na kwayoyin halitta (sabanin yadudduka masu gudanarwa) inda aikin haske ke faruwa.
Layin sufuri na Electron - Wannan Layer yana kunshe da kwayoyin halitta na kwayoyin halitta waɗanda ke jigilar electrons daga cathode.
Cathodes (wanda zai iya zama m ko m, dangane da nau'in OLED) - Lokacin da halin yanzu ke gudana ta cikin na'urar, cathodes suna shigar da electrons a cikin kewaye.
Tsarin luminescence na OLED yawanci yana da matakai na asali guda biyar masu zuwa:
① Carrier allura: karkashin aikin wani waje lantarki filin, electrons da ramukan an allura a cikin Organic aikin Layer sandwiched tsakanin lantarki daga cathode da anode, bi da bi.
② jigilar jigilar kaya: allurar lantarki da ramuka sun yi ƙaura daga layin jigilar lantarki da ramin jigilar ramin zuwa Layer luminescent, bi da bi.
③ Sake haɗawa mai ɗaukar kaya: bayan an yi allurar electrons da ramuka a cikin luminescent Layer, an ɗaure su tare don samar da nau'ikan ramin electron, wato exciton, saboda aikin ƙarfin Coulomb.
④ Exciton ƙaura: Saboda rashin daidaituwa na lantarki da jigilar ramuka, babban yanki na haɓakawa yawanci ba ya rufe dukkanin luminescence Layer, don haka ƙaurawar watsawa zai faru saboda haɓakar hankali.
⑤Exciton radiation yana lalata photons: Canjin radiyo na exciton wanda ke fitar da photon kuma yana fitar da kuzari.
