I-OLED (i-Organic Light-Emitting Diode) ibhekisa kwii-diode ezikhupha ukukhanya kwendalo, ezimele imveliso entsha kwicandelo lee-smartphones. Ngokungafaniyo netekhnoloji ye-LCD yendabuko, itekhnoloji yokubonisa i-OLED ayifuni ukukhanya kwangasemva. Endaweni yoko, isebenzisa izinto ezigqunywe ngezinto zendalo ezibhityileyo kakhulu kunye ne-substrates zeglasi (okanye ii-substrates eziguquguqukayo zendalo). Xa kusetyenziswa umbane, ezi zinto zendalo zikhupha ukukhanya. Ngaphezu koko, izikrini ze-OLED zinokwenziwa zibe lula kwaye zibe ncinci, zinike ii-engile zokubukela ezibanzi, kwaye zinciphise kakhulu ukusetyenziswa kwamandla. I-OLED ikwabizwa ngokuba yitekhnoloji yokubonisa yesizukulwana sesithathu. Izikrini ze-OLED azincinci nje kuphela, zilula, kwaye zisebenza kakuhle ngamandla kodwa zikwanokukhanya okuphezulu, ukusebenza kakuhle kokukhanya, kunye nokukwazi ukubonisa umnyama omsulwa. Ukongeza, zinokugoba, njengoko kubonakala kwiiTV zanamhlanje ezinesikrini esigobileyo kunye nee-smartphones. Namhlanje, abavelisi abakhulu bamazwe ngamazwe babaleka ukunyusa utyalo-mali lwe-R&D kwitekhnoloji yokubonisa i-OLED, nto leyo ekhokelela ekusetyenzisweni kwayo ngokubanzi kwiiTV, iikhompyutha (iimonitha), ii-smartphones, iitablets, kunye nezinye iindawo. NgoJulayi 2022, i-Apple yabhengeza izicwangciso zokwazisa izikrini ze-OLED kuluhlu lwayo lwe-iPad kwiminyaka ezayo. Iimodeli ze-iPad ezizayo zika-2024 ziya kuba neephaneli ze-OLED ezisandula ukwenziwa, inkqubo eyenza ezi paneli zibe ncinci kwaye zibe lula ngakumbi.
Umgaqo wokusebenza kwee-OLED displays wahlukile kakhulu kowee-LCD. Ngokuyintloko ziqhutywa yintsimi yombane, ii-OLED zifumana ukukhutshwa kokukhanya ngokufaka kunye nokudibanisa kwakhona kwezixhobo zokutshaja kwi-organic semiconductor kunye nezinto ezikhanyayo. Ngamafutshane, isikrini se-OLED senziwe zizigidi "zeebhalbhu zokukhanya" ezincinci.
Isixhobo se-OLED siqulathe ikakhulu i-substrate, i-anode, i-hole injection layer (HIL), i-hole transport layer (HTL), i-electron blocking layer (EBL), i-emissive layer (EML), i-hole blocking layer (HBL), i-electron transport layer (ETL), i-electron injection layer (EIL), kunye ne-cathode. Inkqubo yokuvelisa itekhnoloji yokubonisa i-OLED ifuna ubuchule obuphezulu kakhulu bobuchwephesha, obahlulwe ngokubanzi kwiinkqubo zangaphambili nezemva. Inkqubo yangaphambili ibandakanya ikakhulu iindlela ze-photolithography kunye ne-evaporation, ngelixa inkqubo yangasemva igxile kwi-encapsulation kunye netekhnoloji yokusika. Nangona itekhnoloji ye-OLED ephucukileyo ilawulwa kakhulu yi-Samsung kunye ne-LG, abavelisi abaninzi baseTshayina nabo baqinisa uphando lwabo kwizikrini ze-OLED, benyusa utyalo-mali kwizikrini ze-OLED. Iimveliso zesikrini ze-OLED sele zidibene nezinto abazinikelayo. Nangona kukho umsantsa omkhulu xa kuthelekiswa neenkampani ezinkulu zamazwe ngamazwe, ezi mveliso zifikelele kwinqanaba elisebenzisekayo.
