OLED waxay leedahay iftiin sare oo iftiin leh, xagal daawasho ballaaran, jawaab celin degdeg ah, isticmaalka tamarta yar, waxaana laga dhigi karaa aaladaha bandhiga dabacsan, waxaa loo tixgeliyaa inay bedesho tignoolajiyada dareeraha dareeraha ah ee ku habboon jiilka soo socda ee tignoolajiyada soo bandhigida. Qaybta udub-dhexaadka u ah bandhiga OLED waa mid kasta oo-pixel-hoosaad leh oo awood u leh in uu iftiimiyo walxaha iftiimiya OLED. Qaab dhismeedka aasaasiga ah ee walxaha ifaya ee OLED waxaa ka mid ah anode, cathode, iyo sandwiched oo u dhexeeya lakabka shaqeynaya iftiinka iftiinka, kaas oo lakabka iftiinka ifaya Marka loo eego shaqada walxaha OLED ee aaladda iyo qaab dhismeedka aaladda, waxaa loo kala saari karaa lakabka duritaanka godka (HIL), lakabka daloolka daloolka (HTL), lakabka iftiinka-firfircoon (EML) lakabka gaadiidka elektaroonigga ah (ETL).
OLED-yada, lakabka duritaanka daloolka iyo lakabka daloolka daloolka ayaa loo isticmaalaa si loo hagaajiyo waxtarka duritaanka godadka, halka lakabka duritaanka elektarooniga ah iyo lakabka gaadiidka elektaroonigga ah loo isticmaalo si kor loogu qaado waxtarka duritaanka elektarooniga. Qaar ka mid ah walxaha iftiimiya laftoodu waxay leeyihiin shaqada gaadiidka daloolka ama gaadiidka elektaroonigga ah, oo badanaa loo yaqaan 'luminescent'; lakabka walxaha iftiimaya ee qadar yar oo ah fluorescent organic doped ama midabada fosfooraska waxay ka heli karaan jirka ugu muhiimsan ee luminescent ee wareejinta tamarta, iyo qabashada sidaha oo sii daaya midab kala duwan oo iftiin ah, walxaha iftiimiya iftiinka waxaa badanaa sidoo kale loo tixraacaa sida iftiinka martida ama jirka iftiinka soo saara.
2. Mabaadi'da Aasaasiga ah ee Aaladda OLED ee Iftiinka
Danab ayaa lagu dabaqayaa aaladda OLED, godadka iyo elektiroonigga ayaa lagu duraa lakabka OLED ee anode iyo cathode ee aaladda, siday u kala horreeyaan. Godadka iyo elektarooniga ah ee walxaha iftiimiya iftiinka dabiiciga ah oo isku dhafan oo sii daaya tamarta, iyo wareejinta tamarta dheeraadka ah ee wareejinta unugyada unugyada iftiinka-soo-saarka organic, si ay ugu faraxsan yihiin gobolka xiisaha leh, ka dibna exciton ka soo jeeda gobolka xiisaha dib ugu soo noqoshada gobolka, tamarta qaabka sii deynta, iyo ugu dambeyntii garwaaqsadaan electroluminescence ee qalabka OLED.
Guud ahaan, filimka ku jira OLED waxaa ku jira filimka korantada korantada iyo lakab kasta oo walxaha lakabka iftiiminaya. Waqtigan xaadirka ah, anodes-ka aaladaha OLED ee gaaray wax soo saarka ballaaran waxaa badanaa lagu diyaariyaa iyadoo la adeegsanayo tignoolajiyada yaraynta magnetic. Cathodes iyo lakabyada iftiinka dabiiciga ah waxaa badanaa lagu diyaariyaa uumiga faakuumka.
