Izixhobo eziguquguqukayo ze-OLED: Ukuguqula amaShishini amaninzi aneeAplikethi eziQalayo

Itekhnoloji ye-OLED (i-Organic Light Emitting Diode), eyaziwa ngokubanzi ngokusetyenziswa kwayo kwii-smartphones, iiTV eziphezulu, iipilisi, kunye nemiboniso yemoto, ngoku ibonakalisa ixabiso layo ngaphaya kwezicelo zendabuko. Kule minyaka mibini idlulileyo, i-OLED yenze imitsi ebalulekileyo ekukhanyiseni ngobuchule, kuquka izibane zemoto ze-OLED kunye nezibane zokukhusela iliso ze-OLED, ezibonisa amandla ayo amakhulu ekukhanyiseni. Ngaphandle kwemiboniso kunye nokukhanya, i-OLED iya iphononongwa ngakumbi kwimimandla enje ngefotomedicine, izixhobo ezinxitywayo, kunye namalaphu akhanyayo.

Enye yezona zinto zintsha zibalaseleyo kukusetyenziswa kwe-OLED kuyilo lweemoto. Zimnkile iintsuku zezibane zomsila ezidanyazayo. Iimoto zale mihla ngoku zinee "smart tail lights" ezikhupha iipateni zokukhanya ezithambileyo, ezinokwenziwa ngokwezifiso, imibala kunye nemiyalezo. Ezi zibane zomsila zine-OLED zisebenza njengeebhodi zolwazi eziguquguqukayo, ziphucula zombini ukhuseleko kunye nobuntu kubaqhubi.

Umvelisi ophambili waseTshayina we-OLED uye waba phambili kolu tshintsho. USihlalo u-Hu Yonglan wabelane kudliwanondlebe kunye *neNdaba ze-Electronics zaseChina* ukuba izibane zabo ze-OLED zomsila wedijithali zamkelwe ziimodeli ezininzi zeemoto. “Ezi zibane zomsila aziphuculi nje ukhuseleko ngexesha lokuqhuba ebusuku kodwa zikwabonelela ngokhetho olulolwakho kubanikazi beemoto,” ucacise watsho uHu. Kule minyaka mibini idlulileyo, imarike yezibane zomsila ezine-OLED ikhule phantse ngama-30%. Ngokuhla kweendleko kunye nokuqhubela phambili kwitekhnoloji yokubonisa, i-OLED ilindeleke ukuba ibonelele ngezisombululo ezininzi ezahlukeneyo nezinokwenziwa ngokwezifiso kubathengi.

Ngokuchaseneyo nembono yokuba i-OLED iyabiza, iingcali zoshishino ziqikelela ukuba iinkqubo zokukhanya komsila we-OLED zinokunciphisa iindleko ezipheleleyo nge-20% ukuya kwi-30% xa kuthelekiswa nezinye iindlela zendabuko. Ukongeza, iipropathi ezizikhuphayo ze-OLED zisusa imfuno yokukhanya ngasemva, okukhokelela ekusetyenzisweni okuphantsi kwamandla ngelixa kugcinwa amanqanaba aphezulu okukhanya. Ngaphandle kwezicelo zeemoto, i-OLED ibambe amandla amakhulu ekukhanyeni kwekhaya kunye nokukhanya kwendawo yoluntu.

U-Hu Yonglan uphinde wabalaselisa indima ethembisayo ye-OLED kwi-photomedicine. Ukukhanya kudala kusetyenziswa ukunyanga iimeko ezahlukeneyo, ezifana ne-acne enokukhanya okuluhlaza okwesibhakabhaka (400nm-420nm), ukuvuselelwa kwesikhumba kunye nokukhanya okuphuzi (570nm) okanye ukukhanya okubomvu (630nm), kunye nokunyangwa kokutyeba ngokukhanya kwe-635nm ye-LED. Ukukwazi kwe-OLED ukukhupha amaza obude obuthile, kubandakanya kufutshane ne-infrared kunye nokukhanya okuluhlaza okwesibhakabhaka, kuvula amathuba amatsha kwifotomedicine. Ngokungafaniyo nemithombo yemveli ye-LED okanye yelaser, i-OLED ibonelela ngokuthambileyo, ukukhutshwa kokukhanya okufanayo ngakumbi, kuyenza ilungele izixhobo zonyango ezinxitywayo nezibhetyebhetye.

Itekhnoloji ye-Everbright iphuhlise umthombo wokukhanya obomvu oguquguqukayo we-OLED onencopho ye-wavelength ye-630nm, eyenzelwe ukunceda ukuphiliswa kwenxeba kunye nokunyanga ukuvuvukala. Emva kokugqiba uvavanyo lokuqala kunye nokuqinisekiswa, imveliso kulindeleke ukuba ingene kwimarike yezonyango ngo-2025. U-Hu wabonisa ithemba malunga nekamva le-OLED kwi-photomedicine, ecinga ngezixhobo ezinxitywayo ze-OLED zokunakekelwa kwesikhumba kwansuku zonke, ezifana nokukhula kweenwele, ukuphulukiswa kwesilonda, kunye nokunciphisa ukudumba. Ukukwazi kwe-OLED ukusebenza kumaqondo obushushu akufutshane nobushushu bomzimba womntu kwandisa ngakumbi ukufaneleka kwayo kwizicelo ezisondeleleneyo, iguqula indlela esisebenzisana ngayo nemithombo yokukhanya.

Kwindawo yetekhnoloji enxibekayo kunye nempahla, i-OLED yenza amaza. Abaphandi kwiYunivesithi yaseFudan baye baphuhlisa ilaphu eliphezulu le-elektroniki elisebenza njengomboniso. Ngokuluka imisonto yokuluka enemisonto ekhanyayo, badale iiyunithi ze-electroluminescent ze-micrometer-scale. Eli laphu liyintshayo linokubonisa ulwazi ngempahla, linikezela ngamathuba amatsha okwenziwa kweqonga, imiboniso, kunye nokubonakaliswa kobugcisa. Ukuguquguquka kwe-OLED kuyivumela ukuba idityaniswe kwiifom ezahlukeneyo, ukusuka kwiingubo ezintle kunye nobucwebe ukuya kumakhethini, amaphephadonga, kunye nefenitshala, ukudibanisa ukusebenza kunye nobuhle.

Inkqubela phambili yakutsha nje yenze ukuba iintsinga ze-OLED zombane zihlambeke kwaye zomelele, zigcine ukusebenza kakuhle okukhanyayo nakwimozulu embi. Oku kuvula amathuba ezicelo ezinkulu, ezinje ngeebhana ezinikwe amandla e-OLED okanye amakhethini kwiindawo zikawonke-wonke ezifana neevenkile ezinkulu kunye nezikhululo zeenqwelomoya. Ezi ziboniso zikhaphukhaphu, eziguquguqukayo zinokutsala umdla, zigqithise imiyalezo yebhrendi, kwaye zifakwe ngokulula okanye zisuswe, zizenze zilungele zombini ukukhushulwa kwexesha elifutshane kunye nemiboniso yexesha elide.

Njengoko itekhnoloji ye-OLED iqhubeka nokuhambela phambili kwaye iindleko ziyancipha, sinokulindela ukubona iimveliso eziqhutywa yi-OLED kunye neenkonzo ezityebisa ubomi bethu bemihla ngemihla. Ukusuka kwizibane zemoto kunye nonyango lwezonyango ukuya kwitekhnoloji enxitywayo kunye nokubonakaliswa kobugcisa, i-OLED ivula indlela yekamva elikrelekrele, elinobuchule ngakumbi, neliqhagamsheleneyo.
