Isingeniso sezibonisi ze-OLED

Izibonisi ze-OLED (Organic Light-Emitting Diode) zimelela ubuchwepheshe bokubonisa obushintshayo, inzuzo yazo eyinhloko ilele endaweni yazo yokuzikhipha, okuvumela ukulawula ukukhanya okunembile kwezinga le-pixel ngaphandle kwesidingo semojuli yokukhanya kwangemuva. Lesi sici sesakhiwo sinikeza izinzuzo eziphawulekayo njengezilinganiso zokungafani okuphezulu kakhulu, ama-engeli okubuka acishe abe yi-180-degree, kanye nezikhathi zokuphendula ezingeni le-microsecond, kuyilapho isimo sazo esincane kakhulu nesiguquguqukayo sizenza zilungele amadivayisi esikrini asongekayo. Isibonisi se-OLED esijwayelekile siqukethe inqwaba yezingqimba eziningi ehlanganisa ama-substrate, izingqimba ze-electrode, kanye nezingqimba ezisebenzayo ze-organic, lapho ungqimba lwe-organic emissive lufinyelela i-electroluminescence ngokuhlanganiswa kabusha kwe-electron-hole. Ukukhethwa kwezinto ezahlukene ze-organic kuvumela imibala yokukhishwa kokukhanya eguquguqukayo.

Ngokombono womgomo wokusebenza, i-OLED iveza imigodi nama-electron ngokusebenzisa i-anode kanye ne-cathode, ngokulandelana, kanye nalezi zithwali zokushaja ezihlangana kabusha kungqimba olukhiphayo lwezinto eziphilayo ukuze zakhe ama-exciton futhi zikhiphe ama-photon. Le ndlela eqondile yokukhipha ukukhanya ayigcini nje ngokwenza lula isakhiwo sokubonisa kodwa futhi ifinyelela ukusebenza kombala okumsulwa. Njengamanje, ubuchwepheshe buguqukele ezinhlelweni ezimbili ezinkulu zezinto: ama-OLED amancane kanye nama-OLED e-polymer, ngamasu okusebenzisa izidakamizwa ngokunemba athuthukisa ukusebenza kahle okukhanyayo kanye nobumsulwa bombala.

Ezingeni lohlelo lokusebenza, ubuchwepheshe bokubonisa i-OLED bungene emikhakheni eyahlukene njengezinto zikagesi zabathengi, izimoto, kanye namadivayisi ezokwelapha. Ama-smartphone nama-TV aphezulu abusa imakethe ngenxa yekhwalithi yesithombe sabo esiphezulu, kuyilapho izibonisi zezimoto zisebenzisa ukuguquguquka kwazo ukuze zivumele imiklamo yedeshibhodi egobile. Amadivayisi ezokwelapha ayazuza ezicini zawo ezihlukile kakhulu. Ngokuvela kwezinhlobo ezintsha ezifana nama-OLED asobala nama-OLED anwebekayo, ubuchwepheshe bokubonisa i-OLED bukhula ngokushesha bungene emikhakheni ekhulayo njengezinhlelo zasekhaya ezihlakaniphile kanye neqiniso elingeziwe, okubonisa amandla amakhulu okuthuthukiswa.
