Eminyakeni yamuva nje, ngokuthuthuka okusheshayo kobuchwepheshe bokubonisa, ukuboniswa kwe-OLED kuye kwavela njengento okugxilwe kuyo kakhulu esizukulwaneni esisha sobuchwepheshe bokubonisa, okuheha ukunaka okubalulekile kokubili kwezemfundo nezimboni. Ubuchwepheshe bokubonisa i-OLED, obubuye baziwe ngokuthi ubuchwepheshe be-organic-emitting diode, buhlanganisa isakhiwo sesikrini esiyingqayizivele futhi bunobuhle obuningi kunobuchwepheshe be-LCD bendabuko (i-liquid crystal display). Iya ngokuya yamukelwa emkhakheni we-elekthronikhi yabathengi.
Isakhiwo sesikrini se-OLED singaqhathaniswa ngokusobala “nehamburger ekhipha ukukhanya.” Iyunithi ngayinye ye-OLED ifana nesakhiwo sesemishi, into ekhipha ukukhanya esebenza njengongqimba lwemifino phakathi. Ngokukhethekile, ukwakheka kwesibonisi se-OLED ngokuyinhloko siqukethe i-substrate (evame ukwakhiwa ngepulasitiki ekhanyelayo noma i-foil yensimbi ukuze isekelwe), i-anode, isendlalelo sezinto eziphilayo (okuhlanganisa isendlalelo se-conductive kanye nesendlalelo esikhipha umoya), kanye ne-cathode. Isendlalelo se-conductive ngokuvamile sisebenzisa ama-polymers aphilayo njenge-polyaniline ukuthutha izimbobo, kuyilapho ungqimba olukhipha umoya lusiza ukuthuthwa kwama-electron kanye nokukhipha ukukhanya.
Ngokuya ngendlela yokushayela, izikrini ze-OLED zingahlukaniswa zibe izinhlobo ezisebenzayo-matrix (AMOLED) kanye ne-passive-matrix (PMOLED). Ama-OLED e-Active-matrix afakwe ama-transistors amancane-film (TFTs), anciphisa ngempumelelo ukusetshenziswa kwamandla, kuyilapho ama-OLED e-passive-matrix enza kahle kakhulu ezicini ezithile zokusebenza. Ngokungafani nama-LCD, adinga imojula ye-backlight, isikrini se-OLED siyinto ekwazi ukuzenzela engadingi ukukhanya kwangemuva. Lokhu kwenza ukwakheka kwayo kube lula futhi kuletha izinzuzo eziningi, okuhlanganisa ama-engeli okubuka abanzi, izikhathi zokuphendula ngokushesha, umjikelezo wokushayela owenziwa lula, ukusebenza kombala okulula, kanye nekhono lokuzuza amafomu ephaneli aguquguqukayo nagobekayo.
Ngokusekelwe ezimisweni zokuklama zokukhanya, mncane, mfushane, futhi mncane, ubuchwepheshe be-OLED bufaneleka ngokukhethekile kumaphaneli amancane kuya kosayizi omaphakathi. Isivele isetshenziswa kabanzi kubadlali beMP3, omakhalekhukhwini, kanye namadivayisi ahlukahlukene aphathwayo edijithali. Nakuba eminye imikhiqizo ye-OLED isesesigabeni sokuphromotha noma sokuphromothwa kombukiso futhi ingakafaki ukusetshenziswa kwesikali esiphelele, izici zayo zokubonisa ezingenakuqhathaniswa zithole ukuqashelwa kabanzi embonini. Ngokuzayo, njengoba ubuchwepheshe buqhubeka bukhula, isibonisi se-OLED kulindeleke ukuthi sithathele izikrini ze-LCD zendabuko emikhakheni eminingi futhi sibe yisixazululo sokubonisa esijwayelekile.
