Amazi ya kirisiti yerekana (LCD) nigice cyingenzi muri tereviziyo zigezweho, telefone zigendanwa na tableti.Mu ecran ya LCD, diode itanga urumuri (LEDs) itanga urumuri rwera rwera, hanyuma rukamurikirwa kubireba binyuze murwego ruto cyane. Inzira ya kristu igabanyijemo ibice byinshi (pigiseli), kandi itumanaho ryabyo rishobora guhindurwa ukoresheje amashanyarazi. Muri ubu buryo, buri pigiseli isohora urumuri hamwe n’umucyo wihariye (hamwe n’ibara ryerekanwe binyuze muyungurura amabara).
Muri tereviziyo ya tekinike ifite ibikoresho bya LED gakondo, urumuri rukenewe rukorwa na LED amagana; kubera ko LED imwe isaba umwanya munini ugereranije, ntibishoboka kugira umwanya munini.Ibibi biragaragara: ntibishoboka kugera kumatara ya LCD ya ecran imwe rwose hamwe na matrike ya LED itoroshye.Niyo mpamvu, mugihe icyiciro cya mbere cya ecran cyemera ikoranabuhanga rishya rya mini-LED ryasohotse muri 2020, inganda zabyaye ishyaka ryinshi.Kuko mini-LED ari nto cyane (0,05 kugeza 0,2 mm) ugereranije na LED gakondo, ubu birashoboka kubyara amatara kuva ku bihumbi mirongo bya LED-LED isoko tegereza itandukaniro rinini cyane hamwe nabirabura byimbitse.Iyongeyeho, tekinoroji ya mini-LED ninziza mugutanga umusaruro mwinshi cyane (HDR) no gukoresha ingufu nke.
Gukora LED cyangwa mini-LED biragoye cyane kuruta ubworoherane bwubuso bwerekanwe nibigize - cyane cyane ko zimwe muntambwe zikenewe zo gukora zigomba gukorwa mugihe cyimyuka. Muntambwe yambere, MOCVD (Metal Organic Chemical Vapor Deposition) inzira ikoreshwa mugutwikira icyuma kama kama kuri wafer.Muri iki gikorwa, ibintu bitondekanye bifatanye na latisite isanzwe ihari muburyo bwa atomike: gusa ibice bike bya atome byimbitse, bibaho kugirango habeho imiterere ya kristu ya wafer .Kugirango umenye neza ko igifuniko kitarimo umwanda, iyi ntambwe igomba gukorwa hagamijwe gukingirwa icyuho. Aha niho hajyaho umusoro ku nyongeragaciro w’imisoro. Ahantu hanini cyane ku isi ukora sisitemu ya MOCVD-ifite icyicaro gikuru mu Budage, Ubushinwa, na Amerika - bishingiye ku nyongeragaciro ya VAT.
Kugirango habeho impinduka nziza-mbi muri LED, hagomba kubikwa urwego rwinyongera rwa ultra-thin hanyuma rugashyirwa mumwanya ukwiye.Iyi nshingano yoroshye irarangizwa neza binyuze mumikoranire ya plasma ebyiri zongerewe imbaraga za firime: plasma- byongerewe imbaraga zo guhumeka imyuka (PECVD) yo kubitsa ibice, hamwe na plasma ya chimique yumye yumye kugirango ikurweho igice.Kubera ko izi nzira zigomba no gukorwa mubihe bya vacuum, valve ya vacuum nayo ifite uruhare runini hano.
Iyo hari intambwe nyayo ibaye mugihe kizaza, byanze bikunze indangagaciro za TVA zizaba imwe murimwe.Nyuma ya byose, nkuko abahanga babivuga, mini-LEDs ni ihagarara gusa ryerekana urumuri ruto: micro-LED. Ugereranije na mini-LED, ibi ibice bya miniature nyabyo ni bito inshuro 50 kugeza 100.Bitangaje: micro-LED ntoya ifite uburebure bwuruhande rwa microne 3, ni ibihumbi bitatu bya milimetero! Ariko ntabwo itandukaniro ryubunini gusa rituma micro LED zidasanzwe.Ku kuri Ibinyuranye, tekinoroji ya micro-LED yerekana ihinduka ryukuri rya paradigm. Ugereranije na LCD ya ecran, (mini) LED ifite uruhare rwa kabiri rutagaragara nkurwego rwumucyo winyuma. Muri ecran ya micro LED, buri pigiseli irikumurika, ntigishobora kandi kuzimya burundu.Icyerekezo cyinyuma-hamwe na tekinike ijyanye na tekinike-ntigikenewe na gato!
Nubwo Micro-LED ari nto, ingaruka ni nini.Ihinduka kuva kuri micro ikajya kuri tekinoroji ya LED yazanye inyungu nini.Bimwe muribi biragaragara, nkibara ryinshi ryamabara, urumuri rwinshi, itandukaniro rikabije, nigipimo cyihuta cyo kugarura.Ibindi, nko gukoresha ingufu nke nubuzima burebure, ntibigaragara, ariko ningirakamaro kimwe.Muri urwo rwego, igisekuru gishya cya LED kirashoboka cyane ko gihinduka umukino uhinduka.
VAT Group AG yasohoye ibikubiyemo ku ya 14 Ukuboza 2021, kandi ishinzwe gusa amakuru ayirimo. Yatanzwe na rubanda saa 06:57:28 ku ya 14 Ukuboza 2021, isaha ya UTC, idahuje kandi idahinduwe.
