Enye yezinto ezintle kakhulu zetekhnoloji kukuba isizisele iziboniso ze-OLED. Ukuba ukwimarike yomboniso wale mihla kwaye ufuna ukuba ube neempawu ozilindeleyo, kuya kufuneka uphonononge imiboniso ye-OLED. Kweli xesha likhawulezayo, kufanelekile ukwazi izibonelelo ze-OLED zokubonisa.
Yintoni i-OLED?
I-OLED sisishunqulelo se "organic light-emitting diode". Elinye igama yi "organic electroluminescent diode". Ikhupha ukukhanya ngokuthe ngqo ngombane, ngokungafaniyo nendlela yendabuko yokukhanyisa ukukhanya ngokufudumeza i-filament ngombane. Iziboniso ze-OLED zenziwe ngamaleko amancinci eglasi, iplastiki kunye neemolekyuli ezikhethekileyo zezinto eziphilayo ezisabela kwintlawulo yombane kwaye zivelise ubushushu obuphantsi kakhulu. Ukuchukumisa umboniso we-OLED phantse awufudumala, ogcina amandla amaninzi, ophuculo olukhulu ngaphezu kwemiboniso ye-CRT edla amandla yangaphambili.
Imbali yeOLED
Ukufunyanwa kweteknoloji ye-OLED yanamhlanje kunokulandelwa kwi-1987. Ngelo xesha, izazinzulu ezimbini ezivela kuDonman Kodak, uSteven Van Slyke kunye noChing Tang, bafumanisa ezinye izinto eziphilayo ezinokukhupha ukukhanya kumbane ophantsi. Kwangoko ngeminyaka yoo-1960, ukufunyanwa kokulibaziseka kwe-fluorescence kwavula indlela yokuzalwa kwe-OLED. Nangona imathiriyeli yangaphambili ye-organic yayifuna amandla ombane aphezulu ukuze kuphume ukukhanya, izazinzulu ze-Kodak ziphumelele ukufezekisa i-fluorescence kumbane ophantsi.
Ezi nzululwazi zaqala zavelisa ii-OLED ezinombala otyheli-oluhlaza, emva koko i-orenji-red spectrum, kwaye ekugqibeleni zoyisa umthetho we-gap wamandla ukuphumeza ngempumelelo ukukhutshwa kwe-diode ebomvu. Kamva, njengoko iteknoloji iphucula, iziboniso ezintsha ze-OLED ezifana ne-AMOLED (i-matrix esebenzayo ye-organic light-emitting diode) ibonakala.
Amacandelo angundoqo oMboniso we-OLED
Intliziyo yesiboniso se-OLED yi-OLED emitter. Yinto ephilayo ekhupha ukukhanya xa kusetyenziswa umbane. Isakhiwo esisisiseko siquka umaleko wezinto phakathi kwe-anode kunye ne-cathode. Izixhobo zanamhlanje ze-OLED zinamaleko amaninzi okuphucula ukuqina kunye nokusebenza kakuhle, kodwa umsebenzi osisiseko uhlala ufana. Iiphaneli ze-OLED zenziwe ngephaneli yangaphambili, ipaneli yangasemva, i-electrode, i-encapsulation layer, kunye ne-substrate. Le nkqubo inomdla kakhulu kumswakama kunye ne-oksijeni, ngoko ke i-encapsulation layer inzima kakhulu.
