Mu myaka yashize, tekinoroji ya Micro LED yakomeje gutera intambwe, ijyanye no gukenera tekinoroji izerekanwa mu gihe kizaza itwarwa na Metaverse n’imodoka, intego yo gucuruza isa nkaho iri hafi.Muri byo, itara ritukura Micro LED chip yamye ari icyuho cya tekiniki.Nyamara, isosiyete yo mu Bwongereza Micro LED yahinduye ibibi byibikoresho mubyiza, ndetse bigabanya neza inzira kandi bigabanya ibiciro.
Kubera gusobanukirwa byimazeyo ibintu bya nitride ya gallium, Porotech yasohoye Indium Gallium Nitride ya mbere ku isi (InGaN) ishingiye ku mutuku, ubururu n'icyatsi Micro LED yerekanwe umwaka ushize, ikavunika icyuho cy'umutuku, icyatsi n'ubururu bigomba kunyura mu buryo butandukanye ibikoresho, bikemura neza ikibazo cyumucyo utukura Micro LEDs igomba kuvanga sisitemu nyinshi yibikoresho, kandi ntigikoreshwa na substrate iyariyo yose, ishobora kugabanya neza igiciro.
Tekinoroji nyamukuru ya Porotech yibanze kuri "Dynamic Pixel Adjustment," nkuko izina ribigaragaza, ihindura amabara.Zhu Tongtong yasobanuye ko igihe cyose hakoreshejwe chip na pigiseli imwe, ibara iryo ari ryo ryose rishobora kubonwa nijisho ryumuntu rishobora gusohoka, kandi amabara yose ashobora kugaragazwa na nitride ya gallium binyuze mu bucucike buriho no gutwara voltage."Gusa tanga ikimenyetso, irashobora guhindura Ibara, icyatsi iyo ukoraho buto, ubururu, umutuku." Icyakora, "dinamike ya pigiseli ihindura" ntabwo ari ikibazo cya LED gusa, ahubwo inasaba uburyo bwihariye bwo gusubira inyuma no gutwara, gushakisha uburyo bwo gutanga amasoko hamwe nabakora amakoperative kugirango baha abakiriya ibyerekanwe na Micro Display yabo, bityo bisaba igihe kirekire kugirango ushireho.
Zhu Tongtong yanagaragaje ko module nyayo igaragara kandi yerekana amabara menshi azerekanwa mu gice cya kabiri cy'uyu mwaka, bikaba biteganijwe ko hazaba icyiciro cya mbere cya prototypes mu mpera za Kanama no mu ntangiriro za Nzeri.Kubera ko iryo koranabuhanga rigena ibara ryamabara binyuze muburyo bwo gutwara, ibisobanuro byanyuma birangira bigomba gukosorwa kugirango hemezwe ibara ubucucike bwa voltage na voltage bishobora guhinduka;mubyongeyeho, nigice kinini cyane cyo guhuza amabara atatu kuri chip imwe.
Kubera ko nta sub-pigiseli gakondo ihari, iri koranabuhanga rifasha Micro LED kugira ahantu hanini hasohora urumuri, ingano nini ya chip, hamwe nubushobozi buhanitse mugihe kimwe cyo gukemura.Uruhande rwa sisitemu ntirukeneye gusuzuma itandukaniro ryibintu mugihe cyo kwishyira hamwe.Guhuza impamyabumenyi, ntabwo ari ngombwa no gukura umutuku, icyatsi, nubururu epitaxial inshuro imwe, cyangwa guhagarara neza.Byongeye kandi, nyuma yo gukuraho inzitizi zingenzi zakozwe muri Micro LED, irashobora gukemura imikorere yo gusana, kuzamura umusaruro, no kugabanya igiciro cyumusaruro nigihe cyo kwisoko.Nitride ya Gallium ifite ibi biranga, ibara ryera ryibara rimwe rizagenda, kandi ibara rizagenda hamwe nubucucike, bityo rero dushobora gukoresha ibiranga sisitemu yibikoresho kugirango ibara rimwe risukure cyane, mugihe cyose bibujijwe kubintu kandi ibintu bitera umwanda wamabara bivanwaho., mugihe ukoresheje ibara rya drift kugirango ubigereho, urashobora kugera ibara ryuzuye.
Ubushakashatsi kuri Micro LED bugomba gukoresha imitekerereze ya semiconductor
Mubihe byashize, LED gakondo hamwe na semiconductor byari bifite ibidukikije byihariye, ariko Micro LEDs zari zitandukanye.Byombi bigomba guhurizwa hamwe.Uhereye kubikoresho, gutekereza, imirongo yumusaruro, ndetse ninganda zose, bagomba gutera imbere nibitekerezo bya semiconductor.Igipimo cy'umusaruro hamwe na silikoni ishingiye ku ndege bigomba gusuzumwa, hiyongereyeho guhuza sisitemu.Mu nganda za Micro LED, ntabwo igaragara cyane nuburyo bwiza, kandi chip ikurikira, uburyo bwo gutwara hamwe nimpamyabumenyi ijyanye na SOC nayo igomba gutekerezwa.
Ikibazo gikomeye ubu nukugera kubintu bimwe, ubuziranenge, numusaruro kimwe na semiconductor kugirango duhuze kandi duhuze na base ya silicon.Ntabwo LEDs zashyizwe mubikorwa nka LED naho semiconductor zishyirwa mubice nka semiconductor.Byombi bigomba guhuzwa.Usibye imikorere ikomeye ya semiconductor, ibiranga gallium nitride LED nayo igomba gukoreshwa.
Micro LEDs ntikiri LED gakondo, ariko igomba gukorwa hamwe nibitekerezo bya semiconductor.Mugihe kizaza, Micro LED ntabwo ari "icyerekezo gisabwa" gusa.Mugihe kirekire, Micro LED igomba gushyirwa mubikorwa kuri terminal SOC kugirango itezimbere itumanaho n'imikorere.Kugeza ubu, chip nyinshi ziracyari igisubizo cyanyuma.
