Izibonisi ze-OLED (I-Organic Light-Emitting Diode) zimelela ubuchwepheshe bokubonisa obushintshashintshayo, inzuzo yazo eyinhloko ilele endaweni yazo ezizikhiphile, evumela ukulawulwa kokukhanya okunembile kweleveli ye-pixel ngaphandle kwesidingo semojuli yesibani sangemuva. Lesi sici sesakhiwo siletha izinzuzo ezimangalisayo ezifana nezilinganiso zokugqama okuphezulu kakhulu, ama-engeli wokubuka acishe abe ngu-180-degree, nezikhathi zokuphendula zeleveli ye-microsecond, kuyilapho imvelo yazo encane kakhulu futhi eguquguqukayo izenza zilungele amadivayisi esikrini esigoqekayo. Isibonisi esijwayelekile se-OLED siqukethe isitaki sezendlalelo eziningi okuhlanganisa ama-substrates, izendlalelo ze-electrode, nezendlalelo ezisebenzayo eziphilayo, ezinesendlalelo se-organic emissive esithola i-electroluminescence ngokuhlanganisa kabusha imbobo ye-electron. Ukukhethwa kwezinto ezihlukene zemvelo kuvumela imibala ekhishwayo ekhanyayo.
Ngokombono wesimiso sokusebenza, i-OLED ibonisa izimbobo nama-electron nge-anode ne-cathode, ngokulandelanayo, nalezi zinkampani zenethiwekhi eziphinde zihlangane kungqimba lwe-organic emissive ukuze zenze ama-exciton futhi zikhulule ama-photon. Lo mshini okhipha ukukhanya oqondile awenzi nje kuphela ukwakheka kwesibonisi sibe lula kodwa futhi uzuza ukusebenza kombala omsulwa. Njengamanje, ubuchwepheshe buguquke baba izinhlelo ezimbili ezinkulu zezinto ezibonakalayo: ama-OLED ama-molecule amancane nama-OLED e-polymer, ngamasu anembile we-doping athuthukisa ukusebenza kahle okukhanyayo nokuhlanzeka kombala.
Ezingeni lesicelo, ubuchwepheshe bokubonisa i-OLED bungene emikhakheni eyahlukene efana ne-electronics yabathengi, izimoto, kanye nemishini yezokwelapha. Ama-smartphones kanye nama-TV asezingeni eliphezulu abusa imakethe ngenxa yekhwalithi yawo yesithombe ephezulu, kuyilapho izibonisi zezimoto zisebenzisa ukuguquguquka kwazo ukuze zinike amandla imiklamo yedeshibhodi egobile. Imishini yezokwelapha izuza ezicini zayo zokugqama okuphezulu. Ngokuvela kwamafomu amasha afana nama-OLED abonakalayo nama-OLED anwebekayo, ubuchwepheshe bokubonisa i-OLED buyakhula ngokushesha bufinyelele emikhakheni esafufusa njengamasistimu asekhaya ahlakaniphile kanye namaqiniso athuthukisiwe, okubonisa amandla amakhulu okuthuthuka.
