OLED (Organic Light-Emitting Diode) waxaa loola jeedaa diodhyada iftiinka soo saara, kuwaas oo u taagan wax soo saarka cusub ee muuqaalka teleefannada gacanta. Si ka duwan tignoolajiyada soo jireenka ah ee LCD, tignoolajiyada bandhiga OLED uma baahna iftiin danbe. Taa baddalkeeda, waxay isticmaashaa dahaaryo walxaha dabiiciga ah ee aadka u dhuuban iyo substrates dhalo (ama substrates organic dabacsanaan leh). Marka korantada la isticmaalo, walxahan dabiiciga ahi waxay soo saaraan iftiin. Intaa waxaa dheer, muraayadaha OLED waxaa laga dhigi karaa kuwo fudud oo khafiif ah, waxay bixiyaan xaglo daawasho oo ballaaran, waxayna si weyn u yareeyaan isticmaalka tamarta. OLED sidoo kale waxaa lagu amaanaa inay tahay tignoolajiyada soo bandhigida jiilka saddexaad. Bandhigyada OLED kaliya maaha kuwa khafiifsan, fudud, oo tamar badan leh laakiin sidoo kale waxay ku faanaan dhalaal sare, hufnaanta iftiinka sare, iyo awoodda lagu muujiyo madow saafi ah. Intaa waxaa dheer, waa la qalloocin karaa, sida lagu arkay TV-yada casriga ah ee qalloocan iyo taleefannada casriga ah. Maanta, soosaarayaasha waaweyn ee caalamiga ah waxay u tartamayaan inay kor u qaadaan maalgashiga R&D ee tignoolajiyada soo bandhigida OLED, taasoo horseedaysa codsigeeda sii kordheysa ee ku baahsan TV-yada, kombiyuutarada (kormeerayaasha), taleefannada casriga ah, tablet-yada, iyo meelaha kale. Bishii Luulyo 2022, Apple waxay ku dhawaaqday qorshayaal ay ku soo bandhigayso shaashadaha OLED safkeeda iPad-ka sanadaha soo socda. Moodooyinka iPad-ka ee 2024 ee soo socda waxay ka koobnaan doonaan muraayadaha bandhiga ee OLED oo dhowaan nashqadeeyay, habraaca ka dhigaya muraayadahaas xitaa kuwo khafiif ah oo khafiif ah.
Mabda'a shaqada ee bandhigyada OLED ayaa asal ahaan ka duwan kan LCD-yada. Ugu horrayn oo ay kaxayso garoon koronto, OLEDs waxay ku gaadhaan qiiqa qiiqa duritaanka iyo dib-u-habaynta sidayaasha kharashyada ee semiconductor-ka organic iyo walxaha iftiinka. Si fudud loo dhigo, shaashadda OLED waxay ka kooban tahay malaayiin "nalalka iftiinka" oo yaryar.
Qalabka OLED wuxuu inta badan ka kooban yahay substrate, anode, lakabka duritaanka godka (HIL), lakabka gaadiidka godka (HTL), lakabka xannibaadda elektaroonigga ah (EBL), lakabka hawada sare (EML), lakabka xannibaadda (HBL), lakabka gaadiidka elektaroonigga ah (ETL), lakabka duritaanka elektarooniga (EIL), iyo cathode. Habka wax soo saarka ee tignoolajiyada soo bandhigida OLED waxay u baahan tahay aqoon farsamo oo aad u sareysa, oo si ballaaran loo qaybiyay hababka dhamaadka-hore iyo kuwa dambe. Habka-dhamaadka hore ayaa ugu horayn ku lug leh sawir-qaadista iyo farsamooyinka uumi-baxa, halka habka-dhamaadka-dhammaadka uu diiradda saarayo soo koobidda iyo jarida tignoolajiyada. In kasta oo tignoolajiyada horumarsan ee OLED ay inta badan gacanta ku hayaan Samsung iyo LG, shirkado badan oo Shiinees ah ayaa sidoo kale sii xoojinaya cilmi-baaristooda ku aaddan shaashadaha OLED, iyaga oo kordhinaya maalgashiga bandhigyada OLED. Alaabooyinka bandhiga OLED ayaa mar hore lagu daray wax-soo-saarkooda. Inkasta oo farqi weyni u jiro marka loo eego kooxaha caalamiga ah, alaabooyinkani waxay gaadheen heer la isticmaali karo.
