I-OLED inokukhanya kwayo okuphezulu okukhupha ukukhanya, i-angle yokujonga ngokubanzi, impendulo ekhawulezayo, ukusetyenziswa kwamandla aphantsi, kwaye ingenziwa izixhobo zokubonisa eziguquguqukayo, ithathwa njengethatha indawo yeteknoloji yekristale yolwelo efanelekileyo kwisizukulwana esilandelayo sobugcisa bokubonisa. eyona ndawo iphambili yomboniso we-OLED yipixel nganye ekwaziyo ukukhupha ukukhanya kwe-OLED. Isakhiwo esisisiseko se-OLED yokukhanya okukhupha ukukhanya kubandakanya i-anode, i-cathode, kunye ne-sandwiched phakathi kwe-light-emitting functional layer, leyo i-light-emitting layer Ngokomsebenzi wezinto ze-OLED kwisixhobo kunye nesakhiwo sesixhobo, sinokuhlukaniswa njenge-injection ye-injection yomngxuma (HIL), i-hole transport layer (HTL), i-light-emitting layer (EMLE) i-electron enye impahla.
Kwii-OLED, umaleko wenaliti yomngxuma kunye nomaleko wokuthuthwa komngxuma zisetyenziselwa ukuphucula ukusebenza ngokutofelwa kwemingxunya, ngelixa umaleko wenaliti ye-electron kunye nomaleko wothutho lwe-electron zisetyenziselwa ukomeleza ukusebenza ngokutofelwa kwee-electron. Ezinye zezinto ezikhupha ukukhanya ngokwazo zinomsebenzi wokuthutha umngxuma okanye ukuthuthwa kwe-electron, ngokuqhelekileyo kuthiwa yi-luminescent enkulu; Umaleko wezinto ezikhupha ukukhanya kumlinganiselo omncinci wedayi ye-doped organic fluorescent okanye i-phosphorescent yedayi inokufumana ukusuka kumzimba oyintloko we-luminescent wokuhanjiswa kwamandla, kwaye ngokubamba kunye nokukhupha umbala owahlukileyo wokukhanya, imathiriyeli ekhupha ukukhanya idla ngokubizwa ngokuba sisikhanyiso seendwendwe okanye umzimba okhupha ukukhanya.
2. Imigaqo eSisiseko ye-OLED ye-Device Light Emission
I-voltage isetyenziswe kwisixhobo se-OLED, kwaye imingxuma kunye nee-electron zifakwe kwi-OLED layer ukusuka kwi-anode kunye ne-cathode yesixhobo, ngokulandelanayo. Imingxunya kunye nee-electron kwi-organic light-emitting material composite kunye nokukhululwa kwamandla, kunye nokugqithiswa kwamandla okudluliselwa kwe-organic light-emitting material molekyuli, ukuze babe nemincili ukuya kwimo echulumancisayo, kwaye ke i-exciton evela kwimo echulumancisayo ubuyela kwimeko yomhlaba, amandla ngendlela yokukhululwa, kwaye ekugqibeleni baqonde i-electroluminescence yesixhobo se-OLED.
Ngokubanzi, ifilimu kwi-OLED ibandakanya ifilimu ye-electrode eqhubayo kunye nomaleko ngamnye wezinto eziphilayo ezikhupha ukukhanya. Okwangoku, i-anodes yezixhobo ze-OLED ezifumene imveliso yobuninzi zidla ngokulungiswa kusetyenziswa iteknoloji yokunciphisa ulawulo lwamagnetic. I-Cathodes kunye ne-organic luminescent layers zidla ngokulungiswa nge-vacuum evaporation.
