Abakora ibikoresho bya OLED ku isi bateza imbere udushya mu imurikagurisha

Ikoranabuhanga rya Organic Light-Emitting Diode (OLED), rizwi nk'igisubizo cy'ikiganiro gishya cya flat-panel nyuma ya CRT, PDP, na LCD, rikomeje guhindura inganda z'ibikoresho by'ikoranabuhanga bitewe n'imikorere yaryo myiza n'ubushobozi bwaryo bwo gukora ibintu bitandukanye. Rikoresheje ibikoresho bya semiconductor by'umwimerere bitanga urumuri munsi y'amashanyarazi, OLED itanga imiterere ikomeye. guhuza ibyiza bya CRT's ivuguruzanya cyane na LCD'imiterere mito, mu gihe hakurwaho imbogamizi zabayeho mu gihe cy'amateka.

Imiterere n'imikorere bya OLED

Igikoresho gisanzwe cya OLED kigizwe n'ibice byinshi bikora, birimo anode, urwego rwo gushora imyobo (HIL), urwego rwo gutwara imyobo (HTL), urwego rwo gusohora imyobo (EL), urwego rwo gutwara electron (ETL), urwego rwo gutera electron (EIL), na cathode. Ibi bice byakozwe kugira ngo bikore"ingazi"imiterere y’urwego rw’ingufu (Ishusho ya 1), yorohereza gusubirana neza imyobo na electron biri mu gice cy’ingufu zisohora urumuri kugira ngo bitange urumuri. Ubuhanga buhanitse bwo gukoresha doping burushaho kunoza urugero rw’ingufu (Imbonerahamwe ya 1-2), bukongera imikorere myiza y’ibikoresho n’igihe kirekire.

Ibikoresho by'ingenzi byo mu nganda

Ikorwa rya OLED rishingiye ku bikoresho byihariye cyane byagenewe ikoranabuhanga rya passive matrix (PM-OLED) na active matrix (AM-OLED). Sisitemu z'ingenzi zirimo:

PM-OLED: Ibikoresho byo guhumeka no gufunga ibinyabutabire mu buryo bw'umwimerere.

AM-OLED:  Sisitemu zo gusohora: Uburyo bwo gusohora amazi, plasma-enhanced chemical vapor deposition (PECVD), na vacuum thermal evaporation (VTE) yo gukoresha transistor thin-film (TFT).

Ibikoresho byo gushushanya: Ibikoresho byo gusiga irangi, imashini zikoresha ikoranabuhanga, n'ibikoresho by'imashini byumye/bitose byo gukora TFT circuit.

Sisitemu zo gufunga: Amatanura, imiyoboro ya gazi, n'ibikoresho byo gufunga hakoreshejwe laser.

Gupima no gusana: Ibipimo by'amashanyarazi bya TFT, imashini zipima OLED optique, n'imashini zisana laser.

Uruhererekane rw'ibikoresho bya OLED ku isi rwiganjemo inganda zihariye muri Koreya y'Epfo n'Ubuyapani, aho abambere mu nganda batera imbere mu guhanga udushya mu bijyanye no gushyira mu byiciro, gushushanya no gupima neza. Ibigo bikomeye byakomeje inshingano zabyo binyuze mu iterambere mu nganda zikora ibikoresho bigezweho no kunoza umusaruro.Nini ingenzi cyane ku bikoresho bya OLED bitanga umusaruro mwinshi bikoreshwa muri telefoni zigezweho, televiziyo, n'ibikoresho byambarwa.
