OLED ifite urumuri rwinshi rutanga urumuri rwinshi, impande zose zireba, igisubizo cyihuse, gukoresha ingufu nke, kandi birashobora gukorwa ibikoresho byoroshye byerekana, bifatwa nkibisimbuza tekinoroji ya kirisiti nziza yibisekuruza bizaza byerekana ikoranabuhanga. igice cyibanze cya OLED yerekana ni buri sub-pigiseli hamwe nubushobozi bwo gusohora urumuri OLED itanga urumuri. imiterere y'ibanze ya OLED itanga urumuri rurimo anode, cathode, na sandwiched hagati yumurimo ukora urumuri rutanga urumuri, urwego rutanga urumuri Ukurikije imikorere yibikoresho bya OLED mubikoresho hamwe nibikoresho byabigenewe, birashobora gutandukanywa nkigice cyo guteramo umwobo (HIL), urwego rwo gutwara umwobo (HTL), urwego rwo gutwara ibintu bya elegitoronike (ETL).
Muri OLEDs, urwego rwo guteramo umwobo hamwe nu bwikorezi bwo gutwara umwobo bikoreshwa mu kunoza imikorere yo gutera inshinge, mugihe urwego rwo gutera inshinge za elegitoronike hamwe nogutwara ibikoresho bya electron bikoreshwa mukuzamura imikorere ya electron. Bimwe mubikoresho bitanga urumuri ubwabyo bifite umurimo wo gutwara umwobo cyangwa gutwara electron, mubisanzwe bita luminescent nyamukuru; urumuri rutanga urumuri muburyo buke bwa doped organic fluorescent cyangwa irangi rya fosifore irashobora kwakirwa mumubiri nyamukuru wa luminescent yo guhererekanya ingufu, kandi mugutwara abatwara no gusohora ibara ritandukanye ryumucyo, ibikoresho bisohora urumuri mubisanzwe byitwa kandi umushyitsi wumucyo cyangwa umubiri utanga urumuri.
2. Amahame remezo ya OLED Igikoresho cyohereza urumuri
Umuvuduko ukoreshwa mubikoresho bya OLED, kandi imyobo na electron byatewe mumurongo wa OLED uhereye kuri anode na cathode yigikoresho. Imyobo na electron mubikoresho bitanga urumuri kama hamwe nibisohora ingufu, hamwe no guhererekanya ingufu byimura molekile yibintu bitanga urumuri rwumucyo, kuburyo bashimishijwe na reta yishimye, hanyuma exciton kuva muri reta yishimye igasubira mubutaka, ingufu muburyo bwo kurekura, hanyuma amaherezo ikamenya electroluminescence yibikoresho bya OLED.
Muri rusange, firime muri OLED ikubiyemo firime ya electrode ikora kandi buri cyiciro cyibikoresho bitanga urumuri. Kugeza ubu, anode yibikoresho bya OLED byageze ku musaruro rusange mubisanzwe byateguwe hifashishijwe ikoranabuhanga rya mituweli igabanya ubukana. Cathodes hamwe na organic luminescent ibice bisanzwe bitegurwa no guhumeka.
