Kwiminyaka yakutshanje, kunye nokuqhubela phambili ngokukhawuleza kwetekhnoloji yokubonisa, umboniso we-OLED uye wavela njengento ekugxilwe kuyo kwisizukulwana esitsha sobuchwephesha bokubonisa, ukutsala ingqalelo ebalulekileyo kuzo zombini izifundiswa kunye neshishini. Itekhnoloji yokubonisa i-OLED, ekwaziwa ngokuba yitekhnoloji ye-organic-emitting diode, inesakhiwo esikhethekileyo sesikrini kwaye ineengenelo ezininzi ngaphezulu kwetekhnoloji ye-LCD yendabuko (i-liquid crystal display). Iya isanda yamkelwa kwicandelo le-elektroniki yabathengi.
Ubume besikrini se-OLED sinokufaniswa ngokucacileyo "nehamburger ekhupha ukukhanya." Iyunithi nganye ye-OLED ifana nesakhiwo sesandwich, kunye nezinto ezikhupha ukukhanya ezisebenza njengomaleko wemifuno phakathi. Ngokukodwa, i-OLED yokubonisa isakhiwo iquka i-substrate (ehlala yenziwe ngeplastiki ecacileyo okanye i-foil yensimbi yokuxhasa), i-anode, i-organic layer (kubandakanya i-conductive layer kunye ne-emissive layer), kunye ne-cathode. Umaleko wokuqhuba ngokuqhelekileyo usebenzisa iipholima eziphilayo ezifana ne-polyaniline ukuthutha imingxunya, ngelixa umaleko okhutshwayo uququzelela ukuthuthwa kwe-electron kunye nokukhutshwa kokukhanya.
Ngokuxhomekeke kwindlela yokuqhuba, izikrini ze-OLED zingahlelwa zibe zisebenzayo-matrix (AMOLED) kunye neentlobo ze-passive-matrix (PMOLED). Ii-OLED ze-matrix ezisebenzayo zixhotyiswe ngee-transistors zefilimu ezincinci (TFTs), ezinciphisa ngokufanelekileyo ukusetyenziswa kwamandla, ngelixa ii-OLED ze-passive-matrix zigqwesa kwiinkalo ezithile zokusebenza. Ngokungafaniyo neLCDs, ezifuna imodyuli ye-backlight, isikrini se-OLED sisixhobo esizikhuphayo esingadingi ukukhanya ngasemva. Oku kwenza ukuba ulwakhiwo lwayo lube lula kwaye luzise iingenelo ezininzi, kubandakanya ii-engile zokujonga ezibanzi, amaxesha okuphendula akhawulezayo, isekethe yokuqhuba eyenziwe lula, ukusebenza kombala ngokulula, kunye nokukwazi ukufikelela kwiifom zephaneli eziguquguqukayo nezigobekayo.
Ngokusekwe kwimigaqo yoyilo yokukhanya, obhityileyo, omfutshane, kunye nomncinci, itekhnoloji ye-OLED ifanelekile ngokukhethekileyo kwiipaneli ezincinci ukuya eziphakathi. Sele isetyenziswa ngokubanzi kubadlali beMP3, iiselfowuni, kunye nezixhobo ezahlukeneyo zedijithali eziphathwayo. Nangona ezinye iimveliso ze-OLED zisekwiprototype okanye kwinqanaba lokukhuthaza umboniso kwaye azikangeni kwisicelo esisebenzayo esipheleleyo, iimpawu zabo zokubonisa ezingenakulinganiswa ziye zafumana ukuqatshelwa ngokubanzi kwishishini. Kwixesha elizayo, njengoko iteknoloji iqhubeka ikhula, umboniso we-OLED kulindeleke ukuba utshintshe izikrini ze-LCD zendabuko kwiindawo ezininzi kwaye ube sisisombululo esiqhelekileyo sokubonisa.
