Sauyin Nunin OLED

OLED (Organic Light-Emitting Diode) yana nufin diode masu fitar da haske na halitta, waɗanda ke wakiltar sabon samfuri a fagen nunin wayar hannu. Ba kamar fasahar LCD ta gargajiya ba, fasahar nunin OLED ba ta buƙatar hasken baya. Madadin haka, tana amfani da rufin kayan halitta masu siriri da gilashin substrates (ko substrates masu sassauƙa). Lokacin da aka yi amfani da wutar lantarki, waɗannan kayan halitta suna fitar da haske. Bugu da ƙari, ana iya sa allon OLED ya zama mai sauƙi da siriri, yana ba da kusurwoyin kallo masu faɗi, kuma yana rage yawan amfani da wutar lantarki sosai. Ana kuma yaba OLED a matsayin fasahar nuni ta ƙarni na uku. Nunin OLED ba wai kawai siriri ne, mai sauƙi ba, kuma yana da inganci mai ƙarfi, amma kuma yana da haske mafi girma, ingantaccen hasken haske, da ikon nuna baƙi. Bugu da ƙari, ana iya lanƙwasa su, kamar yadda ake gani a cikin talabijin da wayoyin komai da ruwanka na zamani masu lanƙwasa. A yau, manyan masana'antun ƙasashen duniya suna tsere don haɓaka saka hannun jari na R&D a cikin fasahar nunin OLED, wanda ke haifar da yawan amfani da shi a cikin TVs, kwamfutoci (masu saka idanu), wayoyin komai da ruwanka, allunan hannu, da sauran fannoni. A watan Yulin 2022, Apple ta sanar da shirin gabatar da allon OLED a cikin jerin iPad ɗinta a cikin shekaru masu zuwa. Samfurin iPad na 2024 masu zuwa za su ƙunshi sabbin bangarorin nuni na OLED, wani tsari da ke sa waɗannan bangarorin su zama siriri da sauƙi.

Ka'idar aiki na allon OLED ya bambanta da na LCDs. Galibi ana amfani da filin lantarki ne, OLEDs suna samun hasken da ke fitowa ta hanyar allura da haɗakar masu ɗaukar caji a cikin kayan semiconductor na halitta da haske. A taƙaice dai, allon OLED ya ƙunshi miliyoyin ƙananan "ƙwanƙolin haske."

Na'urar OLED galibi ta ƙunshi wani abu mai kama da substrate, anode, layman allurar rami (HIL), layman jigilar rami (HTL), layman toshe wutar lantarki (EBL), layman fitar da wutar lantarki (EML), layman toshe rami (HBL), layman jigilar lantarki (ETL), layman allurar lantarki (EIL), da cathode. Tsarin kera fasahar nunin OLED yana buƙatar ƙwarewa sosai a fasaha, wanda aka raba zuwa hanyoyin gaba da baya. Tsarin gaba ya ƙunshi dabarun daukar hoto da kuma fitar da iska, yayin da tsarin baya ya mayar da hankali kan fasahar rufewa da yankewa. Duk da cewa fasahar OLED mai ci gaba galibi Samsung da LG ne suka ƙware ta, masana'antun China da yawa suna ƙara zurfafa bincike kan allon OLED, suna ƙara saka hannun jari a allon OLED. An riga an haɗa samfuran nunin OLED cikin abubuwan da suke bayarwa. Duk da babban gibi idan aka kwatanta da manyan ƙasashen duniya, waɗannan samfuran sun kai matakin da za a iya amfani da su.
