Cilmi baadhayaashu waxay soo saareen oo soo bandhigeen iftiin cagaaran oo cusub oo nuugaya sawir-qaadayaal dabiici ah oo hufan kuwaas oo aad xasaasi u ah oo la jaan qaadaya hababka wax soo saarka CMOS. Ku darida sawir-qaadayaashan cusub ee dareemayaasha sawirka silikoon waxay faa'iido u yeelan karaan codsiyo badan. Codsiyadan waxaa ka mid ah la socodka garaaca wadnaha ee ku salaysan iftiinka, aqoonsiga faraha iyo aaladaha ogaanaya jiritaanka walxaha u dhow.
Haddii lagu isticmaalo talefannada casriga ah ama kamaradaha sayniska, inta badan dareemayaasha sawir-qaadista ee maanta waxay ku salaysan yihiin tignoolajiyada CMOS iyo sawir-qaadayaasha aan noolayn ee u beddela calaamadaha iftiinka calaamadaha korantada. Inkasta oo sawir-qaadayaasha ka samaysan walxaha organic ay soo jiidanayaan dareenka sababtoo ah waxay gacan ka geysan karaan hagaajinta dareenka, ilaa hadda way adagtahay in la soo saaro sawir-qaadayaasha organic-ga ah ee waxqabadka sare leh.
Sungjun Park, oo ah cilmi-baare ka tirsan jaamacadda Ajou ee Koonfurta Kuuriya, ayaa yidhi: "Ku darista sawir-qaadayaasha organic-ga ah ee wax soo saarka CMOS ee dareemayaasha sawirka waxay u baahan yihiin nuugayaasha iftiinka organic kuwaas oo ay fududahay in lagu soo saaro cabbir ballaaran oo awood u leh aqoonsiga muuqaalka muuqda si loo soo saaro sawirro fiiqan. heerar sarreeya oo mugdi ah. Waxaan sameynay muuqaal hufan, cagaar-xasaasi ah oo dabiici ah oo buuxin kara shuruudahan.”
Cilmi-baadhayaashu waxay sharraxayaan sawir-qaade cusub oo organic ah joornaalka Optica. Waxa kale oo ay abuureen dareemaha sawirka RGB-ga isku-dhafan iyaga oo kor u qaadaya sawir-qaade sawir-qaade ah oo cagaaran oo hufan oo dul-saaraya sawir-qaade silikoon leh filtarrada casaanka iyo buluugga ah.
Kyung-Bae Park, oo ah hogaamiyaha kooxda cilmi-baarista ee Samsung Advanced Institute of Technology (SAIT) ee Kuuriyada Koonfureed, ayaa yiri: "Waad ku mahadsan tahay soo bandhigida lakabka isku-dhafka ah ee dabiiciga ah, lakabka cagaarka ah ee nuugaya cagaarka ayaa la isticmaalay. Dareemayaasha sawirkan waxay si weyn u yareeyaan isdhaafsiga u dhexeeya pixels midabada kala duwan, nashqadan cusubna waxay ka dhigi kartaa photodiodes organic-ga waxqabadka sare leh qayb weyn oo ka mid ah qaybaha sawirka iyo sawir-qaadayaasha codsiyada kala duwan."
Sawir-qaadayaal dabiici ah oo waxtar leh oo dheeraad ah
Inta badan alaabta organic kuma haboona wax soo saarka ballaaran sababtoo ah dareenkooda heerkulka. Uma adkeysan karaan heerkulka sare ee loo isticmaalo daawaynta ka dib ama waxay noqdaan kuwo aan degganayn marka loo isticmaalo heerkul dhexdhexaad ah wakhti dheer. Si looga gudbo caqabadan, saynisyahannadu waxay diiradda saareen wax ka beddelka lakabka kaydinta sawir-qaadaha si loo hagaajiyo xasilloonida, waxtarka, iyo ogaanshaha. Dareen-heliddu waa cabbirka sida wanaagsan ee dareemaha u ogaan karo calaamadaha daciifka ah. "Waxaan soo saarnay khadka qubeyska ee naxaasta ah (BCP): C60 lakabka isku-dhafka ah ee lakabka gaadiidka elektaroonigga ah, kaas oo siinaya sawir-qaadayaasha organic siyaalo gaar ah, oo ay ku jiraan waxtarka sare iyo mugdi aad u hooseeya, kaas oo yareynaya buuqa," ayuu yiri Sungjun Park. Sawir-qaadaha waxaa lagu dhejin karaa photodiode silikoon leh filtarrada casaanka iyo buluugga ah si loo abuuro dareenka sawirka isku-dhafka ah.
Cilmi-baadhayaashu waxay muujinayaan in sawir-qaade cusub uu soo bandhigayo heerarka ogaanshaha marka la barbar dhigo kuwa photodiodes silicon caadiga ah. Qalabka wax baadha waxa uu u shaqaynayay si adag 2 saacadood heerkul ka sareeya 150 °C waxana uu muujiyay xasilooni hawleed oo wakhti dheer ah 30 maalmood 85 °C. Sawir-qaadayaashan ayaa sidoo kale muujinaya waxqabad midab wanaagsan.
Marka xigta, waxay qorsheynayaan inay u habeeyaan sawir-qaadayaal cusub iyo dareemayaasha sawirka isku-dhafka ah ee codsiyada kala duwan, sida dareemayaasha moobilka iyo kuwa la xidhi karo (oo ay ku jiraan dareemayaasha sawirka CMOS), dareemayaasha u dhow, iyo aaladaha faraha ee bandhigyada.
