Ibyiciro bya LED ntoya byiyongereye, kandi batangiye guhangana na DLP na LCD kumasoko yo kwerekana imbere. Dukurikije amakuru ku gipimo cy’isoko ryerekanwa rya LED ku isi hose, kuva 2018 kugeza 2022, ibyiza byo gukora ibicuruzwa bito bito byerekana LED bizagaragara, bikagira inzira yo gusimbuza ikoranabuhanga gakondo rya LCD na DLP.
Gukwirakwiza inganda kubakiriya bato-LED
Mu myaka yashize, LED ntoya ifite iterambere ryihuse, ariko kubera ibiciro nibibazo bya tekiniki, kuri ubu bikoreshwa cyane mubice byerekana umwuga. Izi nganda ntizumva ibiciro byibicuruzwa, ariko bisaba ubuziranenge bwo hejuru bwo kwerekana, bityo zigahita zifata isoko murwego rwo kwerekana ibintu bidasanzwe.
Iterambere rya LED ntoya kuva kumasoko yabugenewe yerekanwe kumasoko yubucuruzi nabasivili. Nyuma ya 2018, uko ikoranabuhanga rigenda rikura n'ibiciro bigabanuka, LED ntoya ntoya yaturikiye ku masoko yerekana ubucuruzi nk'ibyumba by'inama, uburezi, amaduka, hamwe na za sinema. Icyifuzo cyo mu rwego rwo hejuru LED ntoya mu masoko yo hanze kirihuta. Barindwi mu umunani ba mbere ku isi bakora LED bakomoka mu Bushinwa, naho abakora umunani ba mbere bangana na 50.2% by'imigabane ku isoko mpuzamahanga. Nizera ko icyorezo gishya cy'ikamba gihamye, amasoko yo hanze azahita atangira.
Kugereranya ibintu bito bito LED, Mini LED, na Micro LED
Tekinoroji eshatu zavuzwe haruguru zose zishingiye ku tuntu duto twa LED ya kirisiti nka pigiseli ya luminous point, itandukaniro riri hagati yintera yamatara yegeranye nubunini bwa chip. Mini LED na Micro LED irusheho kugabanya itara ryamatara hamwe nubunini bwa chip hashingiwe ku mato mato mato mato, aribwo buryo rusange bwerekezo hamwe niterambere ryiterambere rya tekinoroji yerekana.
Bitewe nubunini bwubunini bwa chip, kwerekana tekinoroji ya tekinoroji ikoreshwa murwego ruzaba rutandukanye, kandi pigiseli ntoya isobanura intera yegeranye.
Isesengura rya Gitoya LED Ikoreshwa rya tekinoroji
SMDni impfunyapfunyo yubuso bwububiko. Chip yambaye ubusa yashyizwe kumurongo, kandi guhuza amashanyarazi bikozwe hagati ya electrode nziza kandi mbi binyuze mumashanyarazi. Epoxy resin ikoreshwa mukurinda amasaro ya SMD LED. Itara rya LED rikorwa no kugurisha ibintu. Amasaro amaze gusudira hamwe na PCB kugirango agire module yerekana module, module yashyizwe kumasanduku yagenwe, kandi amashanyarazi, ikarita yo kugenzura hamwe ninsinga byongeweho kugirango bikore ecran ya LED yuzuye.
Ugereranije nibindi bihe byo gupakira, ibyiza byibicuruzwa bipfunyitse SMD biruta ibibi, kandi bihuye nibiranga isoko ryimbere mu gihugu (gufata ibyemezo, gutanga amasoko, no gukoresha). Nibicuruzwa nyamukuru byinganda kandi birashobora kwakira vuba ibisubizo bya serivisi.
COBinzira ni ugukurikiza byimazeyo LED chip kuri PCB hamwe na kole itwara cyangwa idakora, kandi ugakora umugozi winsinga kugirango ugere kumashanyarazi (inzira nziza yo gushiraho) cyangwa gukoresha tekinoroji ya chip flip-chip (idafite insinga zicyuma) kugirango ikore ibyiza nibibi electrode yamasaro yamatara ihujwe neza na PCB ihuza (tekinoroji ya flip-chip), hanyuma amaherezo module yerekana module irashirwaho, hanyuma module ishyirwa kumasanduku yagenwe, hamwe namashanyarazi, ikarita yo kugenzura ninsinga, nibindi kugirango kora ecran ya LED yerekana. Ibyiza bya tekinoroji ya COB nuko yoroshya inzira yumusaruro, igabanya igiciro cyibicuruzwa, igabanya imikoreshereze y’amashanyarazi, bityo ubushyuhe bwo hejuru bugabanuka, kandi ikinyuranyo kikaba cyiza cyane. Ikibi nuko ubwizerwe buhura nibibazo bikomeye, biragoye gusana itara, kandi urumuri, ibara, na wino biracyagoye gukora Kugirango bihamye.
IMDihuza N amatsinda yamatara ya RGB mugice gito kugirango akore itara. Inzira nyamukuru ya tekiniki: Rusange Yang 4 muri 1, Yin 2 muri 1, Yin 4 muri 1, Rusange Yin 6 muri 1, nibindi byiza byayo biri mubyiza byo gupakira hamwe. Ingano yamatara nini, hejuru yubuso biroroshye, kandi akadomo gato gashobora kugerwaho, bigabanya ingorane zo kubungabunga. Ikibi cyayo nuko urwego rwinganda zubu rutuzuye, igiciro kiri hejuru, kandi kwizerwa guhura nibibazo bikomeye. Kubungabunga ntibyoroshye, kandi guhuza urumuri, ibara, na wino ntibikemutse kandi bigomba kurushaho kunozwa.
Micro LEDni ihererekanya ryinshi rya adresse kuva LED gakondo hamwe na miniaturizasiya kumuzunguruko kugirango ube ultra-fine-pitch LEDs. Uburebure bwa milimetero-urwego LED iragabanuka kugeza kuri micron kugirango igere kuri ultra-high pigiseli na ultra-high resolution. Mubyigisho, irashobora guhuzwa nubunini butandukanye bwa ecran. Kugeza ubu, ikoranabuhanga ryibanze mu gucamo Micro LED ni ugucamo tekinoroji ya miniaturizasiya hamwe n’ikoranabuhanga ryohereza abantu benshi. Icya kabiri, tekinoroji yo kohereza firime yoroheje irashobora kurenga ingano yubunini no kurangiza icyiciro, biteganijwe ko kigabanya ibiciro.
GOBni tekinoroji yo gutwikira ubuso bwose bwubuso bwububiko. Ikubiyemo urwego rwa colloid ibonerana hejuru ya gakondo ya SMD ntoya-nto kugirango ikemure ikibazo cyimiterere ikomeye no kurinda. Mubyukuri, biracyari SMD ibicuruzwa bito-bito. Ibyiza byayo ni ukugabanya amatara yapfuye. Yongera imbaraga zo kurwanya ihungabana no kurinda hejuru yamasaro yamatara. Ibibi byayo ni uko bigoye gusana itara, guhindura imikorere ya module yatewe no guhangayika kwa colloidal, gutekereza, kwangirika kwaho, guhinduranya amabara, hamwe no gusana bigoye gusudira.
