M'zaka zaposachedwa, chifukwa cha kupita patsogolo kwa ukadaulo wowonetsera mwachangu, chiwonetsero cha OLED chakhala chofunikira kwambiri muukadaulo watsopano wowonetsera, zomwe zakopa chidwi chachikulu kuchokera ku maphunziro ndi mafakitale. Ukadaulo wowonetsera wa OLED, womwe umadziwikanso kuti ukadaulo wa organic light-emitting diode, uli ndi mawonekedwe apadera a sikirini ndipo uli ndi zabwino zambiri kuposa ukadaulo wachikhalidwe wa LCD (liquid crystal display). Ukugwiritsidwa ntchito kwambiri mu gawo la zamagetsi.
Kapangidwe ka sikirini ya OLED kangayerekezeredwe bwino ndi "hamburger yotulutsa kuwala." Chigawo chilichonse cha OLED chimafanana ndi kapangidwe ka sandwich, ndipo zinthu zotulutsa kuwala zimagwira ntchito ngati gawo la masamba pakati. Makamaka, kapangidwe ka chiwonetsero cha OLED kamakhala ndi gawo lapansi (nthawi zambiri lopangidwa ndi pulasitiki yowonekera kapena zojambula zachitsulo zothandizira), anode, gawo lachilengedwe (kuphatikiza gawo loyendetsa ndi gawo lotulutsa), ndi cathode. Gawo loyendetsa nthawi zambiri limagwiritsa ntchito ma polima achilengedwe monga polyaniline kunyamula mabowo, pomwe gawo lotulutsa kuwala limapangitsa kuti ma elekitironi ayende bwino komanso kutulutsa kuwala kukhale kosavuta.
Kutengera njira yoyendetsera, zowonetsera za OLED zitha kugawidwa m'magulu a active-matrix (AMOLED) ndi passive-matrix (PMOLED). Ma OLED a Active-matrix ali ndi ma transistors a thin-film (TFTs), omwe amachepetsa kugwiritsa ntchito mphamvu, pomwe ma OLED a passive-matrix ndi abwino kwambiri pazinthu zina. Mosiyana ndi ma LCD, omwe amafunikira gawo la backlight, chowonetsera cha OLED ndi chinthu chodzitulutsa chokha chomwe sichifuna backlight. Izi zimapangitsa kapangidwe kake kukhala kosavuta ndipo kumabweretsa zabwino zambiri, kuphatikiza ma angles owonera ambiri, nthawi yoyankha mwachangu, dera loyendetsa losavuta, magwiridwe antchito amitundu yosavuta, komanso kuthekera kopanga mawonekedwe osinthasintha komanso opindika.
Kutengera mfundo zopangira kukhala zopepuka, zopyapyala, zazifupi, komanso zazing'ono, ukadaulo wa OLED ndi woyenera kwambiri pamapanelo ang'onoang'ono mpaka apakatikati. Umagwiritsidwa ntchito kale kwambiri mu osewera a MP3, mafoni am'manja, ndi zida zosiyanasiyana zonyamulika. Ngakhale kuti zinthu zina za OLED zikadali mu gawo lotsatsira kapena chiwonetsero ndipo sizinagwiritsidwe ntchito mokwanira, mawonekedwe awo osayerekezeka awonetsedwa kwambiri mumakampani. M'tsogolomu, pamene ukadaulo ukupitirira kukula, chiwonetsero cha OLED chikuyembekezeka kulowa m'malo mwa zowonetsera zachikhalidwe za LCD m'magawo ambiri ndikukhala yankho lodziwika bwino la zowonetsera.
