M'zaka zaposachedwa, ndikupita patsogolo kofulumira kwaukadaulo wowonetsera, chiwonetsero cha OLED chawoneka ngati chofunikira kwambiri pamibadwo yatsopano yaukadaulo wowonetsera, kukopa chidwi chachikulu kuchokera kumaphunziro ndi mafakitale. Tekinoloje yowonetsera ya OLED, yomwe imadziwikanso kuti ukadaulo wa organic-emitting diode, imakhala ndi mawonekedwe apadera azithunzi ndipo ili ndi maubwino angapo kuposa ukadaulo wakale wa LCD (liquid crystal display). Ikuchulukirachulukira kutengera gawo la ogula zamagetsi.
Mawonekedwe a skrini ya OLED angayerekezedwe bwino ndi "hamburger yotulutsa kuwala." Chigawo chilichonse cha OLED chimafanana ndi kamangidwe ka masangweji, ndi zinthu zotulutsa kuwala zomwe zimakhala ngati masamba apakati. Makamaka, mawonekedwe owonetsera a OLED amakhala ndi gawo lapansi (nthawi zambiri limapangidwa ndi pulasitiki yowonekera kapena chitsulo chothandizira), anode, wosanjikiza wachilengedwe (kuphatikiza wosanjikiza wowongolera ndi wosanjikiza), ndi cathode. Ma conductive layer nthawi zambiri amagwiritsa ntchito ma polima achilengedwe monga polyaniline kunyamula mabowo, pomwe gawo lotulutsa mpweya limathandizira mayendedwe a ma elekitironi ndi kutulutsa kuwala.
Kutengera ndi njira yoyendetsera, zowonera za OLED zitha kugawidwa m'mitundu yogwira-matrix (AMOLED) ndi passive-matrix (PMOLED). Ma OLED a Active-matrix ali ndi ma transistors a film-film (TFTs), omwe amachepetsa kugwiritsa ntchito mphamvu, pomwe ma OLED a passive-matrix amapambana pazinthu zina. Mosiyana ndi ma LCD, omwe amafunikira gawo la backlight, chophimba cha OLED ndi chinthu chodzipangira chokha chomwe sichifunikira kuwala kwambuyo. Izi zimapangitsa kuti mawonekedwe ake azikhala osavuta komanso amabweretsa zabwino zambiri, kuphatikiza ma angles owoneka bwino, nthawi yoyankha mwachangu, kuyendetsa kosavuta, mawonekedwe osavuta amitundu, komanso kuthekera kopeza mawonekedwe osinthika komanso opindika.
Kutengera mfundo zopangira kukhala zopepuka, zowonda, zazifupi, ndi zazing'ono, ukadaulo wa OLED ndiwoyenera makamaka pamapanelo ang'onoang'ono mpaka apakatikati. Imagwiritsidwa ntchito kale pamasewero a MP3, mafoni am'manja, ndi zida zosiyanasiyana zama digito. Ngakhale zinthu zina za OLED zikadali pagawo lachiwonetsero kapena zotsatsira ziwonetsero ndipo sizinalowebe ntchito zonse, mawonekedwe awo osayerekezeka adziwika kwambiri pamsika. M'tsogolomu, pamene teknoloji ikupitirira kukula, chiwonetsero cha OLED chikuyembekezeka kusintha zowonetsera zachikhalidwe za LCD m'madera ambiri ndikukhala njira yowonetsera.
