Mu ikoranabuhanga rigezweho muri iki gihe, ecran za LED zagiye zigaragara cyane muri ecran z’imijyi, mu mazu y’imikino yo mu rugo, mu bitaramo byo ku rubyiniro, n’ibindi byinshi, bikunzwe cyane kubera urumuri rwazo rwinshi n’amabara meza. Inyuma y’ubu bunararibonye butangaje bw’amashusho, ibintu bidasanzwe byo mu isi bigira uruhare runini rudasimburwa.
Ibintu by'isi bidasanzwe Ntibyitiriwe ubuke ahubwo byitiriwe ingorane zo kubikuramo no kubitandukanya. Bitewe n’imiterere yabyo yihariye y’umubiri n’iya chimique, ibi bintu byabaye "intwaro y’ibanga" yo kunoza imikorere ya ecran ya LED.
Gukoresha imiti igabanya ubushyuhe mu butaka birushaho kunoza imikorere y'urumuri.isi idasanzwe ibintu bigize LED z'ubururu, ntibyongera imikorere y'urumuri gusa kandi bigabanya ingufu z'amashanyarazi yo gutwara, ahubwo binatuma igihe cyo kubaho cya LED kirushaho kuba cyiza.Ibi bivuze ko ecran za LED zirushaho gukoresha ingufu nke kandi zigahendutse mu kubungabunga
Ibintu by'isi bidasanzwe Nanone kandi, birakomeye mu kunoza imiterere ya LED. Gukoresha imirasire y'ubutaka budasanzwe bituma urumuri rusohoka rwegera urumuri rusanzwe, bikongera ubuziranenge bw'amabara kandi bigatuma habaho uburyo bworoshye bwo kureba. Byaba ari ugutanga amashusho meza cyangwa amatara meza cyane, imirasire y'ubutaka budasanzwe ituma amashusho arushaho kugaragara neza kandi asa n'ay'ukuri.
Byongeye kandi, rare earths zituma ubushyuhe bw'amabara ya LED bukomera cyane. Mu gihe cy'ubushyuhe butandukanye n'ubushuhe bw'ibidukikije, rare earth-doped LEDs zigumana ubushyuhe bw'amabara buhamye, bigatuma amabara adahinduka cyangwa ngo ahinduke.
Hari ahantu hadasanzwe nk'aho cerium (Ce)na europium (Eu) byongera ubukana bw'urumuri binyuze mu kwinjiza urumuri rw'ubururu no kuruhindura urumuri rw'umuhondo, bigatuma ibimenyetso bigaragara neza ndetse no mu rumuri rwinshi rwo hanze.
Ikigaragara ni uko gukoresha imiti igabanya ubushyuhe mu bintu bidasanzwe (rare earth doping) binoza ubudahangarwa bw’imirasire ya LED z’ubururu, bigabanya ibyago byo kwangirika kw’imirasire, kandi bigabanya ubushyuhe mu mikorere, bikarinda kwangirika k’imikorere no kugabanuka k’ubuzima bitewe no gushyuha cyane.
Uko ikoranabuhanga rigenda ritera imbere,ikoreshwa ry'ubutaka budasanzwemu mashusho ya LED azarushaho kwiyongera. Mu gihe kizaza, dushobora kwitega ko amashusho ya LED azakoresha ingufu nke, asobanutse neza kandi ahamye, atanga umusaruro mwizae biteye ubwoba ibirori bigaragarira amaso. Inyuma ya byose, ibintu by'isi bidasanzwe bazakomeza kugaragaza agaciro kabo gadasanzwe nk'imbaraga zikoresha ikoranabuhanga ryo kwerekana.
