OLED ili ndi kuwala kwake komwe kumatulutsa kuwala kwambiri, kuyang'ana kwakukulu, kuyankha mofulumira, kugwiritsira ntchito mphamvu zochepa, ndipo kungapangidwe zipangizo zowonetsera, zimaganiziridwa kuti zilowe m'malo mwa teknoloji ya crystal yamadzimadzi yabwino kwa mbadwo wotsatira wa teknoloji yowonetsera. gawo lapakati la chiwonetsero cha OLED ndi pixel iliyonse yokhala ndi mphamvu yotulutsa kuwala kwa OLED. kamangidwe ka OLED kuwala-emitting element zikuphatikizapo anode, cathode, ndi sandwiched pakati pa kuwala-emitting zinchito wosanjikiza, amene kuwala-emitting wosanjikiza Malinga ndi ntchito ya OLED zipangizo mu chipangizo ndi kapangidwe kachipangizo, tingasiyanitsidwe monga dzenje jekeseni wosanjikiza (HIL), dzenje zoyendera wosanjikiza (HTL), kuwala-emitting wosanjikiza (EML) electron jekeseni (EML) jekeseni wa elekitironi (EML)
Mu ma OLED, wosanjikiza wa jekeseni wa dzenje ndi wosanjikiza wa dzenje amagwiritsidwa ntchito kukonza bwino jekeseni wa mabowo, pomwe jekeseni wa ma elekitironi ndi mayendedwe a ma elekitironi amagwiritsidwa ntchito kupititsa patsogolo mphamvu ya jakisoni wa ma elekitironi. Zina mwazinthu zotulutsa kuwala zimakhala ndi ntchito yoyendetsa dzenje kapena zoyendera ma elekitironi, zomwe nthawi zambiri zimatchedwa luminescent yayikulu; wosanjikiza wa zinthu zopepuka zotayira pang'ono mu utoto wocheperako wa fulorosenti kapena utoto wa phosphorescent ukhoza kulandira kuchokera ku thupi lalikulu lowunikira la kusamutsa mphamvu, ndipo pogwidwa ndi chonyamulira ndi kutulutsa mtundu wina wa kuwala, zinthu zotulutsa kuwala nthawi zambiri zimatchedwanso kuwala kwa alendo kapena thupi lotulutsa kuwala.
2. Mfundo Zazikulu za OLED Chipangizo Chowala Kutulutsa
Mpweya umagwiritsidwa ntchito pa chipangizo cha OLED, ndipo mabowo ndi ma electron amalowetsa mu OLED wosanjikiza kuchokera ku anode ndi cathode ya chipangizocho, motsatira. Mabowo ndi ma elekitironi mu organic kuwala-zimatulutsa zinthu gulu ndi kumasula mphamvu, ndi zina kutengerapo mphamvu kutengerapo organic kuwala-emitting zinthu mamolekyulu, kotero kuti amasangalala ndi dziko osangalala, ndiyeno exciton ku dziko osangalala kubwerera ku dziko lapansi, mphamvu mu mawonekedwe a kumasulidwa, ndipo pamapeto pake kuzindikira electroluminescence ya chipangizo OLED.
Nthawi zambiri, filimuyo mu OLED imaphatikizapo filimu yopangira ma elekitirodi ndi gawo lililonse la zinthu zosanjikiza zotulutsa kuwala. Pakadali pano, ma anode a zida za OLED zomwe zakwanitsa kupanga misa nthawi zambiri zimakonzedwa pogwiritsa ntchito ukadaulo wowongolera maginito. Ma cathodes ndi organic luminescent zigawo nthawi zambiri amakonzedwa ndi vacuum evaporation.
