Mubihe byashize, igihe twitaye kuri Micro LED, ntitwashoboraga kwirinda ingingo igoye yo "kwimura abantu benshi".Uyu munsi, nibyiza gusimbuka ingoyi ya chip hanyuma tukaganira kuri iki kibazo munzira ya miniaturizasi ya LED.Reka turebe impinduka zijyanye no kurwanya imihindagurikire y'ikirereMini LEDkuri Micro LED, ifishi yo gupakira, ibikoresho bya luminescent na shoferi IC.Ninde uzajya muburyo rusange?Ninde uzashira mubitekerezo byacu?
Kuva mukibuga gito kugeza Micro LED, ni izihe mpinduka zizabaho muburyo bwibicuruzwa bipfunyitse?
Urebye kubipakira, LED yerekanwe irashobora kugabanywamo ibihe bitatu: ikibuga gito, Mini na Micro.Ibihe bitandukanye byo gupakira bifite ibicuruzwa bitandukanyeLED yerekanaibikoresho.1. Igikoresho kimwe-pigiseli 3-muri-1 igikoresho cyo gutandukanya SMD: 1010 ni uhagarariye bisanzwe;2. Ubwoko bwa pake yo gutandukanya ibikoresho AIP: Bane murimwe ni uhagarariye bisanzwe;3. Gufata hejuru ya GOB: SMD ubushyuhe busanzwe bwamazi ni uguhagararira bisanzwe;4. Gupakira byuzuye COB: ubushyuhe busanzwe bwamazi ya glue isanzwe ihagarariye.
Mugihe cya Mini LED, hari ubwoko bubiri bwingenzi bwibicuruzwa: byose-muri-kimwe ibikoresho byihariye hamwe nububiko bwuzuye.Ubusanzwe uhagarariye SMT ni byose-muri-kimwe nibikoresho bitandukanye.Ubusanzwe uhagarariye module igaragara ni ugupakira.Tekinoroji yububiko bwuzuye iracyafite ibibazo nkibara rya wino nibara rihoraho, umusaruro, nigiciro.Igikoresho cyo gutandukanya 0505 ni imipaka ya SMD.Kugeza ubu, ihura ahanini nubwizerwe, imikorere ya SMT, itera nibindi bibazo.Mugihe cya Mini LED, irashobora kuba yatakaje inzira nyamukuru yikoranabuhanga.Mugihe cya Micro LED, ntagushidikanya ko izahuzwa no gupakira.Ariko icyibandwaho cyikibazo nukwimura chip.
Kubijyanye no guhanura ibizakorwa muri tekinoroji ya LED yerekanwe, hari ingingo enye zingenzi:1. Tekinoroji yo gupakira yagiye ihinduka kuva tekinoroji yapakiye kugeza kubipfunyika bwa tekinoroji yo hejuru, ihura na LED miniaturisation.Iyi izaba inzira yo kugabanya intambwe zo gukora no kugabanya ibiciro bya sisitemu.2. Kuva kuri Umwe muri umwe, Bane muri umwe kugeza N muri imwe.Ifishi yo gupakira iroroshye.3. Urebye ubunini bwa chip hamwe n'akadomo, nta guhagarika kuva Mini LED kugeza kuri micro LED.4. Urebye ku isoko rya terefone, icyerekezo cya LED kizaza kiva mu buhanga no gukodesha ku isoko ryerekana ibicuruzwa.Inzibacyuho kuva kwerekana "ecran" yerekanwe "igikoresho".
Mubihe bya Mini LED na Micro LED, bite kuri fosifore?
Mini LED / Micro LED yuzuye-chip yerekana muri rusange itoneshwa naYayoboye inganda, ariko ibibazo byo kwimura kwinshi mubikorwa byo gukora, kugenzura amabara menshi ya chip hamwe no kwitandukanya bitandukanye nabyo biragaragara cyane.Mbere yuko ibibazo byavuzwe haruguru bikemuka burundu, guteza imbere fosifore nshya ishimishijwe nubururu Mini LED / Micro LED kugirango wirinde kubura ikoranabuhanga risanzweho no guha amahirwe yose ibyiza bya tekiniki nuburyo bwubuhanga busuzumwa ninganda.Ariko rero, birakenewe gukemura ikibazo cyubunini buto bwa fosifore nigihombo cyiza cyatewe nubunini buke.
Kugeza ubu, Mini LED iracyakwiriye inganda za LCD nkisoko yinyuma, ariko ntabwo ifite inyungu yikiguzi.Uyu munsi, urwego rwinganda rwamazi ya kirisiti yerekana amabara gamut ashingiye kumasoko mashya ya LED yamurika yarenze 90% NTSC.Ubushakashatsi bwakozwe ku isi budasanzwe bwageze ku musaruro mwinshi no gukoresha fluoride ya bande.Mugutsindira gushya gushya-bande gusohora fosifori itukura nicyatsi hamwe n'amatara ya LED.Ibi bifasha kurushaho kongera amabara ya gamut ya flux ya kristu yerekanwe kuri 110% NTSC, igereranywa na tekinoroji ya OLED / QLED.
Mubyongeyeho, ahari kwant dot ibikoresho bitanga urumuri nabyo bishobora kugira uruhare.Ariko kwant dot luminescent ibikoresho "bisa neza" kandi byahawe ibyiringiro byinshi.Nyamara, ibibazo byumutekano, imikorere yumucyo, kurengera ibidukikije nigiciro kinini cyo gukoresha ntabwo byakemuwe neza.Byongeye kandi, fotoluminescent ya kwantu ni inzibacyuho.Porogaramu nyayo ya kwantumumwanya uri muri QLED.Kugeza ubu, isi imwe nimwe idasanzwe yashyizeho iterambere ryibikoresho bya luminescent ya QLED.
Kuki LED yumwimerere yerekana uburyo bwo gutwara idakora mugihe cya Mini na Micro LED?
Iyo LED yerekanwe yinjiye muri Micro LED na Mini LED, uburyo bwa LED bwerekana uburyo bwo gutwara ntibushobora gukoreshwa.Impamvu nyamukuru ni ahantu haboneka.Muri rusange, gakondoLED yerekanaumushoferi IC arashobora gutwara pigiseli zigera kuri 600, kandi kubera ko LED yerekanwe mubusanzwe ikoreshwa mukarere karenga santimetero 120, ubunini bwa IC ntibuzatera ibibazo.Ariko, niba pigiseli imwe ihuye nubunini bwikaye cyangwa terefone igendanwa, IC zingana kandi numubare ntizishobora guhura nigikoresho cyikaye cyangwa terefone igendanwa, bityo Micro LED na Mini LED bisaba uburyo butandukanye bwo gutwara.
Mubisanzwe, disiki yuburyo bwo kwerekana irashobora kugabanwa muburyo bubiri.Ubwoko bwa mbere ni Passive Matrix.Mubisanzwe passiyo isobanura ko gusa iyo pigiseli ya skaneri ikozwe nubu cyangwa voltage hazaba hasohotse urumuri.Igihe gisigaye kitasuzumwe ntigikora.Kubera ko ubu buryo bukora kumurongo umwe gusa mugihe cya buri cyiciro cyo guhindura, biragoye cyane kugera kubisabwa byokemuka cyane hamwe numucyo mwinshi kumurongo umwe.Kandi mugihe cyose hari uruziga rugufi muri imwe muri pigiseli, biroroshye gutera ibimenyetso byambukiranya.
Mubyongeyeho, hari nubushakashatsi bukoresha transistor yinyongera nka switch kugirango wirinde kwangiriza ibimenyetso biterwa nibibazo bigize ibice.Inzira zose, ibikorwa biracyari pasiporo.Kugeza ubu, ubu buryo bwo gutwara bukoreshwa cyane mubisubizo bito bitewe nubushakashatsi bworoshye bwumuzunguruko hamwe nigiciro gito.Nka siporo yambara ibikomo.Niba hari hakenewe panne-reaction yo hejuru, modul nyinshi-ntoya irashobora gukoreshwa muguhuza, nka ecran nini yerekana.
Ubundi bwoko bwo gutwara ni Matrix ikora.Nkuko izina ribigaragaza, Matrix ikora irashobora gukomeza kugumana imbaraga za voltage cyangwa imiterere yubu binyuze mububiko bwa pigiseli ubwayo murwego rwikadiri.Kuberako capacitor ikoreshwa mububiko, hariho kandi ibibazo byo kumeneka no kwambukiranya ibimenyetso, ariko ni bito cyane kuruta gutwara gusa.Uburyo bwo gutwara ibinyabiziga busanzwe buracyafite ikibazo cyuburinganire buterwa na tristoriste yoroheje ya tristoriste hamwe nigikoresho gisohora urumuri ubwacyo murwego rwo hejuru.Kubwibyo, haribintu byinshi bigoye byubatswe nkubu nka 7T1C cyangwa 5T2C kugirango bikemure ikibazo cyuburinganire.
Iyo ingano ya pigiseli ari nto kurwego runaka kandi ibisabwa byo gukemura biri hejuru cyane, uburyo bwa digitale ya digitale izakoreshwa ibishoboka byose kugirango ikibazo cyuburinganire kivuzwe haruguru.Mubisanzwe, ubugari bwa pulse modulasiyo (PWM) ikoreshwa muguhindura imvi.kubyara ibara ritandukanye.
Uburyo bwa PWM bukoresha cyane cyane ibice bya pulse byagabanijwe mugihe cyigihe kugirango habeho impinduka zitandukanye zumuhondo uhindura igihe cyo kuzimya no kuzimya.Ubu buhanga bushobora nanone kwitwa moderi cycle modulation.Kubera ko LED ahanini igizwe nibikoresho bigezweho, mugushushanya micro-LED yerekana micro, uburyo bwo gushushanya isoko yigenga isanzwe yigenga ikoreshwa mugutwara buri pigiseli yigenga kugirango ihuze ibisabwa nubucyo bumwe hamwe nuburebure buhamye..
