Sanadihii la soo dhaafay, iyadoo horumarka degdega ah ee tignoolajiyada bandhigga, bandhigga OLED wuxuu u soo baxay diiradda weyn ee jiilka cusub ee tignoolajiyada soo bandhigida, soo jiidashada dareenka weyn ee tacliinta iyo warshadaha labadaba. Tignoolajiyada soo bandhigida OLED, oo sidoo kale loo yaqaanno tignoolajiyada iftiinka-baxa organic, waxay leedahay qaab-dhismeed shaashad gaar ah waxayna leedahay faa'iidooyin badan marka loo eego tignoolajiyada LCD-ga caadiga ah (muujinta crystal-ka dareeraha ah). Waxaa si isa soo taraysa looga qaadanayaa qaybta macaamiisha elektiroonigga ah.
Qaab dhismeedka muraayadda OLED si cad ayaa loo barbar dhigi karaa "hamburger iftiin leh." Cutub kasta oo OLED ah wuxuu u eg yahay qaab-dhismeedka sandwich, oo leh walxaha iftiiminaya u dhaqma sida lakabka khudradda ee dhexda. Gaar ahaan, qaab dhismeedka bandhiga OLED wuxuu inta badan ka kooban yahay substrate (badanaa laga sameeyay caag hufan ama bir bir ah oo taageero ah), anode, lakab dabiici ah (oo ay ku jiraan lakabka korantada iyo lakabka wasakhaysan), iyo cathode. Lakabka korantada wuxuu caadi ahaan isticmaalaa polymers-ka organic sida polyaniline si uu u qaado godadka, halka lakabka sii daaya uu fududeeyo gaadiidka elektaroonigga ah iyo qiiqa qiiqa.
Iyada oo ku xidhan habka wadista, shaashadaha OLED waxaa loo kala saari karaa noocyo firfircoon-matrix (AMOLED) iyo matrix dadban (PMOLED). Active-matrix OLEDs waxay ku qalabaysan yihiin transistor-filim khafiif ah (TFTs), kuwaas oo si wax ku ool ah u yareeya isticmaalka awoodda, halka matrix-ka OLED-yadu ay ka sarreeyaan dhinacyada waxqabadka qaarkood. Si ka duwan LCD-yada, kuwaas oo u baahan moduleka iftiinka dambe, OLED screen waa walxo is-muujin ah oo aan u baahnayn iftiin dambe. Tani waxay ka dhigaysa qaab-dhismeedkeeda mid fudud oo keenaya faa'iidooyin badan, oo ay ku jiraan xaglaha daawashada ballaaran, waqtiyada jawaabta degdegga ah, wareegga wadista oo la fududeeyay, midab fudud oo hawlkar ah, iyo awoodda lagu gaaro foomamka guddiga dabacsan oo la laaban karo.
Iyada oo ku saleysan mabaadi'da naqshadeynta ee ahaanshaha fudud, dhuuban, gaaban, iyo yar yar, tignoolajiyada OLED waxay si gaar ah ugu habboon tahay muraayadaha yaryar iyo kuwa dhexdhexaadka ah. Waxaa mar hore si weyn loogu isticmaalay MP3 ciyaartoyda, telefoonnada gacanta, iyo qalabyada dhijitaalka ah ee kala duwan ee la qaadi karo. Inkasta oo qaar ka mid ah alaabooyinka OLED ay weli ku jiraan prototype ama marxaladda xayeysiinta bandhigga oo aan weli gelin codsi wax ku ool ah oo dhammaystiran, sifooyinkooda bandhig ee aan la barbar dhigi karin ayaa helay aqoonsi ballaaran oo warshadaha ah. Mustaqbalka, sida tignoolajiyadu sii wado qaan-gaadhka, bandhiga OLED ayaa la filayaa inuu beddelo shaashadaha LCD-ga caadiga ah ee meelo badan oo uu noqdo xalka bandhigga caadiga ah.
