OLED ifite urumuri rwayo rutanga urumuri rwinshi, inguni nini yo kureba, igisubizo cyihuse, ikoreshwa ry'ingufu nke, kandi ishobora gukorwa ibikoresho byo kwerekana byoroshye, ifatwa nk'aho isimbuye ikoranabuhanga rya crystal y'amazi rikwiriye ikoranabuhanga rigezweho ryo kwerekana. Igice cy'ingenzi cya ecran ya OLED ni buri pixel ifite ubushobozi bwo gutanga urumuri rwa OLED. Imiterere y'ibanze ya element ya OLED itanga urumuri irimo anode, cathode, na sandwiched hagati y'urwego rutanga urumuri, aho urwego rutanga urumuri Dukurikije imikorere y'ibikoresho bya OLED mu gikoresho n'imiterere y'igikoresho, bishobora gutandukanywa nka hole injection layer (HIL), hole transport layer (HTL), hole injection layer (EML) electron transport layer (ETL), electron injection layer (EIL) n'ibindi bikoresho.
Muri OLED, urwego rwo gushyiramo imyobo n'urwego rwo gutwara imyobo bikoreshwa mu kunoza imikorere y'imyobo, mu gihe urwego rwo gushyiramo electron n'urwego rwo gutwara electron bikoreshwa mu kunoza imikorere y'imyobo. Bimwe mu bikoresho bitanga urumuri ubwabyo bifite akazi ko gutwara imyobo cyangwa gutwara electron, ubusanzwe byitwa urwego rukuru rwo gutanga urumuri; urwego rw'ibikoresho bitanga urumuri mu gipimo gito cy'irangi rya fluorescent cyangwa phosphorescent rishobora kwakira mu mubiri munini w'urumuri rw'ingufu, kandi binyuze mu gufata no gutanga ibara ritandukanye ry'urumuri, ibikoresho bitanga urumuri bikunze kwitwa kandi umubiri w'urumuri w'umushyitsi cyangwa umubiri w'urumuri utanga urumuri.
2. Amahame y'ibanze yo gusohora urumuri rw'ibikoresho bya OLED
Umuvuduko w'amashanyarazi ushyirwa ku gikoresho cya OLED, hanyuma imyobo na electron bishyirwa mu cyiciro cya OLED bivuye kuri anode na cathode by'igikoresho, uko bikurikirana. Imyobo na electron biri mu bikoresho bitanga urumuri bya organic bivanze kandi birekura ingufu, hamwe n'ingufu zo kohereza izindi molekile zitanga urumuri rwa organic, ku buryo zishishikajwe n'imiterere y'ibyishimo, hanyuma exciton iva muri state y'ibyishimo igaruka muri state y'ubutaka, ingufu mu buryo bwo kurekura, kandi amaherezo zibona electroluminescence y'igikoresho cya OLED.
Muri rusange, filime iri muri OLED irimo filime ya electrode iyobora amashanyarazi hamwe na buri cyiciro cy'ibikoresho by'urwego rutanga urumuri rw'umwimerere. Muri iki gihe, anode z'ibikoresho bya OLED byageze ku musaruro mwinshi akenshi zitegurwa hakoreshejwe ikoranabuhanga ryo kurwanya amashanyarazi. Cathodes n'urwego rutanga urumuri rw'umwimerere akenshi bitegurwa hakoreshejwe amashanyarazi aturuka mu kirere.
