Magulu a ma LED ang'onoang'ono awonjezeka, ndipo ayamba kupikisana ndi DLP ndi LCD pamsika wowonetsera mkati. Malinga ndi kuchuluka kwa msika wapadziko lonse lapansi wowonetsa ma LED, kuyambira 2018 mpaka 2022, zabwino zamachitidwe azinthu zazing'ono zowonetsera za LED zidzakhala zodziwikiratu, ndikupanga chizolowezi cholowa m'malo mwaukadaulo wakale wa LCD ndi DLP.
Kugawa kwamakampani kwamakasitomala ang'onoang'ono a LED
M'zaka zaposachedwa, ma LED ang'onoang'ono apeza chitukuko chofulumira, koma chifukwa cha mtengo ndi zovuta zamakono, pakali pano amagwiritsidwa ntchito makamaka m'madera owonetsera akatswiri. Mafakitalewa samakhudzidwa ndi mitengo yazinthu, koma amafunikira mawonekedwe apamwamba kwambiri, motero amangotenga msika mwachangu paziwonetsero zapadera.
Kupanga ma LED ang'onoang'ono kuchokera kumsika wodzipatulira kupita kumisika yamalonda ndi anthu wamba. Pambuyo pa 2018, pamene teknoloji ikukhwima ndi kuchepa kwa mtengo, ma LED ang'onoang'ono aphulika m'misika yowonetsera malonda monga zipinda zochitira misonkhano, maphunziro, masitolo, ndi malo owonetsera mafilimu. Kufunika kwa ma LED ang'onoang'ono otsika kwambiri m'misika yakunja kukukulirakulira. Opanga asanu ndi awiri mwa asanu ndi atatu otsogola padziko lonse lapansi a LED akuchokera ku China, ndipo opanga asanu ndi atatu apamwamba amapanga 50.2% ya msika wapadziko lonse lapansi. Ndikukhulupirira kuti mliri watsopano ukakhazikika, misika yakunja iyamba posachedwapa.
Kuyerekeza kwa ma LED ang'onoang'ono, Mini LED, ndi Micro LED
Matekinoloje atatu omwe ali pamwambapa onse adatengera tinthu tating'ono tating'ono ta kristalo ta LED ngati ma pixel owala, kusiyana kuli patali pakati pa mikanda yoyandikana nayo ndi kukula kwa chip. Mini LED ndi Micro LED zimachepetsanso kusiyana kwa mikanda ya nyali ndi kukula kwa chip pamaziko a ma LED ang'onoang'ono, omwe ndi njira yayikulu komanso chitukuko chaukadaulo wamtsogolo.
Chifukwa cha kusiyana kwa kukula kwa chip, magawo osiyanasiyana aukadaulo owonetsera adzakhala osiyana, ndipo kamvekedwe kakang'ono ka pixel kumatanthauza mtunda wowonera pafupi.
Kuwunika kwaukadaulo wa Small Pitch LED Packaging Technology
Zithunzi za SMDndi chidule cha pamwamba phiri chipangizo. Chip chopanda kanthu chimayikidwa pa bulaketi, ndipo kugwirizana kwa magetsi kumapangidwa pakati pa ma electrode abwino ndi oipa kudzera mu waya wachitsulo. Epoxy resin imagwiritsidwa ntchito kuteteza mikanda ya nyali ya SMD LED. Nyali ya LED imapangidwa ndi reflow soldering. Mikandayo ikalumikizidwa ndi PCB kuti ipange gawo lowonetsera, gawoli limayikidwa pabokosi lokhazikika, ndipo mphamvu, khadi yowongolera ndi waya zimawonjezeredwa kuti apange chiwonetsero chazithunzi cha LED.
Poyerekeza ndi zochitika zina zopakira, zabwino zazinthu zopakidwa za SMD zimaposa zovuta zake, ndipo zimagwirizana ndi zomwe zimafunikira msika wapakhomo (kupanga zisankho, kugula, ndi kugwiritsa ntchito). Ndiwonso zinthu zomwe zimagwiritsidwa ntchito pamakampani ndipo zimatha kulandira mayankho a ntchito mwachangu.
COBndondomeko ndi kumamatira mwachindunji LED Chip kwa PCB ndi zomatira kapena sanali conductive guluu, ndi kuchita waya kugwirizana kukwaniritsa magetsi kugwirizana (zabwino kukwera ndondomeko) kapena kugwiritsa ntchito Chip flip-chip luso (popanda zitsulo mawaya) kuti zabwino ndi zoipa. ma elekitirodi a nyali mkanda mwachindunji olumikizidwa kwa PCB kugwirizana (flip-chip luso), ndipo potsiriza chiwonetsero chagawo gawo aumbike, ndiyeno gawo anaika pa bokosi anaika, ndi mphamvu, kulamulira khadi ndi waya, etc. pangani chiwonetsero chomaliza cha LED. Ubwino waukadaulo wa COB ndikuti umathandizira kupanga, kumachepetsa mtengo wazinthu, kumachepetsa kugwiritsa ntchito mphamvu, motero kutentha kwapamtunda kumachepetsedwa, ndipo kusiyanitsa kumakhala bwino kwambiri. Choyipa ndichakuti kudalirika kumayang'anizana ndi zovuta zazikulu, zimakhala zovuta kukonza nyali, ndipo kuwala, mtundu, ndi mtundu wa inki zimakhala zovuta kuchita Kuti zisagwirizane.
IMDamaphatikiza magulu a N a mikanda ya nyali ya RGB kukhala kagawo kakang'ono kuti apange mkanda wa nyali. Njira yayikulu yaukadaulo: Common Yang 4 mu 1, Common Yin 2 mu 1, Common Yin 4 mu 1, Common Yin 6 mu 1, ndi zina zambiri. Kukula kwa mikanda ya nyali ndikokulirapo, kukwera pamwamba kumakhala kosavuta, ndipo kadontho kakang'ono kamatha kutheka, zomwe zimachepetsa zovuta kukonza. Zoyipa zake ndikuti unyolo wamakampani omwe ulipo pano siwokwanira, mtengo wake ndi wapamwamba, ndipo kudalirika kukukumana ndi zovuta zazikulu. Kukonza n’kovuta, ndipo kusasinthasintha kwa kuwala, mtundu, ndi mtundu wa inki sikunathe kuthetsedwa ndipo kukufunika kukonzedwanso.
Micro LEDndikusamutsa kuchuluka kwa maadiresi kuchokera kumayendedwe achikhalidwe a LED ndi miniaturization kupita kugawo laling'ono kuti apange ma LED apamwamba kwambiri. Kutalika kwa millimeter-level LED kumachepetsedwanso mpaka mulingo wa micron kuti akwaniritse ma pixel apamwamba kwambiri komanso kusamvana kopitilira muyeso. M'malingaliro, imatha kusinthidwa kukhala makulidwe osiyanasiyana azithunzi. Pakadali pano, ukadaulo wofunikira mubotolo la Micro LED ndikudutsa ukadaulo wa miniaturization ndi ukadaulo wosinthira misa. Kachiwiri, ukadaulo wowonda wamakanema umatha kudutsa malire a kukula ndikumaliza kusamutsa kwa batch, zomwe zikuyembekezeka kuchepetsa mtengo.
GOBndi teknoloji yophimba pamwamba pa ma modules okwera pamwamba. Imayika gawo la colloid yowonekera pamtunda wa ma module a SMD ang'onoang'ono kuti athetse vuto la mawonekedwe amphamvu ndi chitetezo. M'malo mwake, akadali chinthu chaching'ono cha SMD. Ubwino wake ndikuchepetsa magetsi akufa. Zimawonjezera mphamvu zotsutsana ndi kugwedezeka ndi chitetezo cha pamwamba pa mikanda ya nyali. Zoyipa zake ndikuti ndizovuta kukonza nyali, kusinthika kwa gawo lomwe limayambitsidwa ndi kupsinjika kwa colloidal, kusinkhasinkha, degumming m'deralo, kusinthika kwamtundu wa colloidal, komanso kukonza zovuta zowotcherera.
