Amadivayisi Aguquguqukayo e-OLED: Ukuguqula Izimboni Eziningi Ngezinhlelo Zokusebenza Ezintsha

Ubuchwepheshe be-OLED (Organic Light Emitting Diode), obaziwa kabanzi ngokusetshenziswa kwabo kuma-smartphones, ama-TV asezingeni eliphezulu, amaphilisi, nezibonisi zezimoto, manje bufakazela inani labo ukwedlula izinhlelo zokusebenza ezivamile. Eminyakeni emibili edlule, i-OLED yenze amagxathu abalulekile ekukhanyeni okuhlakaniphile, okuhlanganisa namalambu emoto e-OLED ahlakaniphile namalambu e-OLED avikela amehlo, okubonisa amandla ayo amakhulu ekukhanyiseni. Ngaphandle kwezibonisi nokukhanya, i-OLED iqhubeka ihlolwa emikhakheni efana ne-photomedicine, amadivayisi agqokekayo, nezindwangu ezikhanyayo.

Enye yezinto ezintsha ezigqama kakhulu ukusetshenziswa kwe-OLED ekwakhiweni kwezimoto. Sezadlula izinsuku zamalambu omsila acwayizayo. Izimoto zesimanje manje zifaka “amalambu ahlakaniphile” akhipha amaphethini okukhanya athambile, enziwa ngendlela oyifisayo, imibala, ngisho nemilayezo yombhalo. Lezi zibani zomsila ezinamandla ze-OLED zisebenza njengamabhodi olwazi ashukumisayo, athuthukisa kokubili ukuphepha nokwenza kube ngokwakho kubashayeli.

Umkhiqizi ohamba phambili waseShayina we-OLED ubehamba phambili kulokhu kuqanjwa kabusha. USihlalo u-Hu Yonglan wabelane engxoxweni ne-*China Electronics News* ukuthi amalambu abo e-OLED omsila wedijithali asetshenziswe amamodeli ezimoto ezimbalwa. “Lawa malambu awagcini nje ngokuthuthukisa ukuphepha uma ushayela ebusuku kodwa aphinde anikeze abanikazi bezimoto izinketho eziqondene nawe,” kuchaza uHu. Kule minyaka emibili edlule, imakethe yezibani zomsila ane-OLED ikhule cishe ngo-30%. Ngokuncipha kwezindleko nokuthuthuka kobuchwepheshe bokuboniswa, i-OLED kulindeleke ukuthi inikeze izixazululo ezihluke kakhulu nezingenziwa ngezifiso kubathengi.

Ngokuphambene nombono wokuthi i-OLED iyabiza, ochwepheshe bezimboni balinganisela ukuthi amasistimu okukhanya komsila we-OLED angehlisa izindleko zizonke ngo-20% kuya ku-30% uma kuqhathaniswa nezinye izindlela ezivamile. Ukwengeza, izici ezizikhiphayo ze-OLED ziqeda isidingo sokukhanyisa kabusha, okuholela ekusetshenzisweni kwamandla okuphansi kuyilapho kugcinwa amazinga aphezulu okukhanya. Ngaphandle kwezinhlelo zokusebenza zezimoto, i-OLED inamandla amakhulu ekukhanyisweni kwekhaya okuhlakaniphile nokukhanyisa kwesikhungo somphakathi.

U-Hu Yonglan uphinde wagqamisa indima ethembisayo ye-OLED ku-photomedicine. Ukukhanya kudala kusetshenziswa ekwelapheni izimo ezahlukahlukene, njengezinduna ezinokukhanya okuluhlaza okunamandla amakhulu (400nm–420nm), ukuvuselelwa kwesikhumba okuphuzi (570nm) noma ukukhanya okubomvu (630nm), ngisho nokwelashwa kokukhuluphala ngokukhanya kwe-LED okungu-635nm. Ikhono le-OLED lokukhipha ubude beza obuthile, okuhlanganisa ukukhanya okuseduze kwe-infrared kanye nohlaza okwesibhakabhaka okujulile, kuvula amathuba amasha ku-photomedicine. Ngokungafani nemithombo yendabuko ye-LED noma ye-laser, i-OLED inikeza ukukhanya okuthambile, okufanayo okufanayo, okuyenza ifaneleke kumadivayisi ezokwelapha agqokekayo nezivumelana nezimo.

I-Everbright Technology isungule umthombo wokukhanya we-OLED oguquguqukayo obomvu onobude obuphakeme obungu-630nm, oklanyelwe ukusiza ukuphulukiswa kwamanxeba nokwelapha ukuvuvukala. Ngemva kokuphothula ukuhlolwa kokuqala nokuqinisekiswa, umkhiqizo kulindeleke ukuthi ungene emakethe yezokwelapha ngo-2025. U-Hu uzwakalise ithemba ngekusasa le-OLED ku-photomedicine, ebona ngeso lengqondo amadivayisi e-OLED agqokekayo okunakekelwa kwesikhumba kwansuku zonke, njengokukhula kwezinwele, ukuphola kwesilonda, nokunciphisa ukuvuvukala. Amandla e-OLED okusebenza emazingeni okushisa aseduze nokushisa komzimba womuntu athuthukisa futhi ukufaneleka kwayo kwezinhlelo zokusebenza eziseduze, iguqule indlela esisebenzisana ngayo nemithombo yokukhanya.

Emkhakheni wobuchwepheshe obugqokekayo nezindwangu, i-OLED nayo yenza amagagasi. Abacwaningi baseFudan University benze indwangu ye-elekthronikhi ephezulu kakhulu esebenza njengesibonisi. Ngokuluka imicu ye-weft eguquguqukayo enezintambo ezikhazimulayo ezisontayo, bakha amayunithi e-electroluminescent esikali se-micrometer. Le ndwangu emisha ingabonisa ulwazi lwezimpahla zokugqoka, inikeze amathuba amasha emidlalo yasesiteji, imibukiso, nokuvezwa kobuciko. Ukuvumelana nezimo kwe-OLED kuyivumela ukuthi ihlanganiswe ezinhlotsheni ezihlukahlukene, kusukela ezimpahleni ezihlakaniphile nobucwebe kuye kumakhethini, amaphephadonga, nefenisha, okuhlanganisa ukusebenza nobuhle.

Intuthuko yakamuva yenze imicu ye-elekthronikhi ye-OLED yashezeka futhi yahlala isikhathi eside, igcina ukusebenza kahle okukhazimulayo okuphezulu ngisho nasezimweni zezulu ezinzima. Lokhu kuvula amathuba ezinhlelo zokusebenza ezinkulu, njengezibhengezo ezinamandla ze-OLED noma amakhethini ezindaweni zomphakathi njengezitolo ezinkulu nezikhumulo zezindiza. Lezi zibonisi ezingasindi, nezivumelana nezimo zingadonsa ukunaka, zidlulisele imilayezo yomkhiqizo, futhi zifakwe noma zisuswe kalula, zizenze zilungele kokubili ukuphromotha kwesikhashana kanye nemibukiso yesikhathi eside.

Njengoba ubuchwepheshe be-OLED buqhubeka nokuthuthuka futhi nezindleko zincipha, singalindela ukubona imikhiqizo namasevisi amaningi aqhutshwa yi-OLED ecebisa ukuphila kwethu kwansuku zonke. Kusukela ekukhanyisweni kwezimoto nokwelashwa kuye kobuchwepheshe obugqokekayo nokuveza ubuciko, i-OLED ivula indlela yekusasa elihlakaniphile, elinobuhlakani ngokwengeziwe, nelixhumene.
