Toban sano ka hor, telefishinnada CRT iyo kormeerayaasha waaweyn ayaa ku badnaa guryaha iyo xafiisyada. Maanta, waxaa lagu bedelay bandhigyo fidsan oo qurxoon, iyadoo TV-yada muraayadda qalloocan ay soo jiiteen dareenka sannadihii u dambeeyay. Kobcintan waxa horseed ka ah horumarka tignoolajiyada soo bandhigida-laga bilaabo CRT ilaa LCD, iyo hadda tignoolajiyada OLED ee aadka loo filayo.
OLED (Organic Light-Emitting Diode) waa aalad koronto-luminescent ah oo ku saleysan walxo dabiici ah. Qaab dhismeedkeedu waxa uu u eg yahay "sandwich", oo leh lakabyo badan oo organic ah oo la dhex galiyay laba electrodes. Marka danab la isticmaalo, walxahan waxay tamarta korontada u beddelaan iftiin muuqda. Adiga oo naqshadeynaya isku dhafka dabiiciga ah ee kala duwan, OLED waxay soo saari kartaa casaan, cagaar, iyo buluug - midabada aasaasiga ah ee isku dhafan si ay u abuuraan sawirro firfircoon. Si ka duwan bandhigyada dhaqameed, OLED uma baahna iftiin dambe, oo awood u siinaya dhuuban, dabacsanaan, iyo xitaa shaashado laalaabi karo oo khafiif ah sida qayb ka mid ah timaha bini'aadamka.
Dabacsanaanta OLED waxay beddeshay tignoolajiyada bandhigga. Shaashadaha mustaqbalka waxa laga yaabaa in aanay ku koobnaan qalab dhaqameed laakiin waxa lagu dhex dari karaa dharka, daahyada, iyo walxaha kale ee maalinlaha ah, iyada oo la ogaanayo aragtida "bandhigyada meel kasta ku yaal." Bandhigyada ka baxsan, OLED waxay sidoo kale haysaa ballanqaad weyn xagga iftiinka. Marka la barbardhigo iftiinka caadiga ah, OLED waxay bixisaa iftiin jilicsan, iftiin la'aan ah oo aan lahayn shucaac waxyeello leh, taas oo ka dhigaysa mid ku habboon nalalka indhaha ku habboon, iftiinka matxafka, iyo codsiyada caafimaadka.
Laga soo bilaabo CRT ilaa OLED, horumarka tignoolajiyada soo bandhigida kaliya ma wanaajin waayo aragnimada laakiin sidoo kale waxay ballan qaadaysaa inay beddeleyso qaab nololeedkeena. Qaadashada baahsan ee OLED waxay u gogol xaaraysaa mustaqbal ifaya oo caqli badan.
