ʻO nā kiʻi LED pitch pitch liʻiliʻi me ka hoʻohana ʻana i ka ʻenehana encapsulation COB ua kapa ʻia ʻo "hanau lua" hōʻike LED pitch pitch liʻiliʻi.Mai ka makahiki i hala aku nei, ua hōʻike kēia ʻano huahana i ke ʻano o ka ulu ʻana o ka mākeke kiʻekiʻe a ua lilo ʻo ia i "koho maikaʻi loa" alanui no kekahi mau hōʻailona e kālele ana i nā kikowaena kauoha kiʻekiʻe a me nā kikowaena hoʻouna.
SMD, COB i ka MicroLED, nā ʻano o ka wā e hiki mai ana no nā pale LED Pitch Nui
ʻO COB kahi pōkole o English ChipsonBoard.ʻO ka ʻenehana mua loa i hoʻokumu ʻia i ka makahiki 1960.He "hoʻolālā uila" ka manaʻo e hoʻomaʻamaʻa i ke ʻano o ka pūʻolo o nā mea uila ultra-fine a hoʻomaikaʻi i ka paʻa o ka huahana hope.ʻO ka ʻōlelo maʻalahi, ʻo ke ʻano o ka pōʻai COB ʻo ia ka mea maoli, ʻōpala a i ʻole nā mea uila i kūʻai pololei ʻia ma ka papa kaapuni a uhi ʻia me kahi resin kūikawā.
Ma nā noi LED, hoʻohana nui ʻia ka pūʻulu COB i nā ʻōnaehana kukui mana kiʻekiʻe a me ka hōʻike LED pitch pitch liʻiliʻi.Manaʻo ka mea mua i nā pono hoʻomaha i lawe ʻia e ka ʻenehana COB, ʻoiai ʻaʻole ka mea hope e hoʻohana piha i nā pono kūpaʻa o COB i ka hoʻoilo ʻana o ka huahana, akā loaʻa pū kekahi i ke ʻano o ka "hopena hana".
ʻO nā pōmaikaʻi o COB encapsulation ma nā kiʻi LED pitch pitch liʻiliʻi: 1. Hāʻawi i kahi kahua hoʻomaha maikaʻi.No ka mea, ʻo ka ʻeke COB he aniani ʻāpana pili pono me ka papa PCB, hiki iā ia ke hoʻohana piha i ka "wahi substrate" no ka hoʻokō ʻana i ka wela a me ka wela.ʻO ka pae hoʻoheheʻe wela ke kumu nui e hoʻoholo ai i ke kūpaʻa, ka helu defect rate a me ke ola lawelawe o nā pale liʻiliʻi pixel pitch LED.ʻOi aku ka maikaʻi o ka hoʻoheheʻe ʻana i ka wela ma ke ʻano maoli.
2. ʻO ka pūʻolo COB he hale i hoʻopaʻa ʻia.Hoʻopili ʻia ka papa kaapuni PCB, nā ʻāpana aniani, nā wāwae wili a me nā alakaʻi, etc.ʻIke ʻia nā pōmaikaʻi o kahi hale i hoʻopaʻa ʻia - no ka laʻana, ka makū, ka puʻupuʻu, ka ʻinoʻino, a me ka maʻalahi o ka hoʻomaʻemaʻe ʻana i ka ʻili.
3. Hiki ke hoʻolālā ʻia ka pūʻolo COB me nā hiʻohiʻona ʻokoʻa "hōʻike optics".No ka laʻana, hiki ke uhi ʻia kona ʻano pōʻai, ka hoʻokumu ʻana o kahi wahi amorphous, me nā mea ʻeleʻele ʻeleʻele.ʻOi aku ka maikaʻi o ka huahana COB ma ke ʻano like ʻole.No kekahi laʻana, hiki i ka pōʻai COB ke hana i nā hoʻololi hou i ka hoʻolālā optical ma luna o ke aniani e ʻike ai i ka naturalization o nā ʻāpana pixel a hoʻomaikaʻi i nā hemahema o ka nui o nā ʻāpana ʻoi a me ka ʻālohilohi o nā pale liʻiliʻi pixel pitch LED maʻamau.
4. ʻAʻole hoʻohana ʻo COB encapsulation crystal soldering i ka mauna SMT reflow soldering process.Akā, hiki iā ia ke hoʻohana i ke "kaʻina hana kūʻai haʻahaʻa haʻahaʻa" me ka hoʻopili ʻana i ka puʻe wela, ka wili ultrasonic, a me ka hoʻopili uea gula.Hana kēia i nā ʻāpana aniani LED semi-conductor ʻaʻole i pili i nā wela kiʻekiʻe ma mua o 240 degere.ʻO ke kaʻina hana wela kiʻekiʻe ke kumu nui o nā wahi make LED liʻiliʻi a me nā kukui make, ʻoi aku ka nui o nā kukui make.Ke hōʻike ʻia ke kaʻina hana hoʻopili make i nā kukui make a pono e hoʻoponopono ʻia, e hana pū ʻia "ka lua kiʻekiʻe-mehana reflow soldering".Hoʻopau loa ke kaʻina hana COB i kēia.ʻO kēia hoʻi ke kī i ka helu ʻino o ke kaʻina COB he hoʻokahi hapaʻumi wale nō o nā huahana mauna i luna.
ʻOiaʻiʻo, loaʻa i ke kaʻina COB kona "nāwaliwali."ʻO ka mea mua ke kumu kūʻai.ʻOi aku ke kumukūʻai o ke kaʻina COB ma mua o ke kaʻina hana mauna.ʻO kēia no ka mea ʻo ke kaʻina COB he pae encapsulation maoli, a ʻo ka mauna ʻili ka hoʻohui terminal.Ma mua o ka hoʻokō ʻia ʻana o ke kaʻina hana mauna ʻili, ua hoʻokō ʻia nā ʻāpana aniani LED i ke kaʻina encapsulation.ʻO kēia ʻokoʻa ka mea i loaʻa i ka COB nā paepae hoʻopukapuka kiʻekiʻe, nā paepae kumukūʻai, a me nā paepae ʻenehana mai ka hiʻohiʻona ʻoihana pale LED.Eia nō naʻe, inā hoʻohālikelike ʻia ka "puke kukui a me ka hoʻohui terminal" o ke kaʻina hana i luna me ke kaʻina COB, ʻae ʻia ka hoʻololi ʻana o ke kumukūʻai, a aia ke ʻano o ka emi ʻana o ke kumukūʻai me ka paʻa o ke kaʻina hana a me ka hoʻomohala ʻana i ka pālākiō noi.
ʻO ka lua, ʻo ka ʻike like ʻana o nā huahana encapsulation COB e koi i nā hoʻoponopono ʻenehana hope loa.Hoʻopili i ka hina hina o ka encapsulating glue ponoʻī a me ka kūlike o ka pae o ka mālamalama o ka aniani e hoʻomālamalama ana i ke kukui, hoʻāʻo ia i ka mana o ka maikaʻi o ke kaulahao ʻoihana holoʻokoʻa a me ke kiʻekiʻe o ka hoʻoponopono hope.Eia naʻe, ʻoi aku ka maikaʻi o kēia hemahema i ka "ʻike palupalu."Ma o keʻano o ka holomua o kaʻenehana,ʻo ka hapa nui o nā hui o kaʻoihana iʻike i nāʻenehana koʻikoʻi no ka mālamaʻana i ka nānā pono o ka hana nui.
ʻO ke kolu, hoʻonui nui ʻo COB encapsulation i nā huahana me ka spacing pixel nui i ka "paʻakikī hana" o ka huahana.ʻO ia hoʻi, ʻaʻole ʻoi aku ka maikaʻi o ka ʻenehana COB, ʻaʻole pili i nā huahana me ka spacing P1.8.No ka mea ma kahi mamao loa, e lawe mai ʻo COB i nā piʻi koʻikoʻi nui.- Ua like kēia me ke kaʻina hana i luna ʻaʻole hiki ke hoʻololi piha i ka hōʻike LED, no ka mea ma ka p5 a i ʻole nā huahana, ʻo ka paʻakikī o ke kaʻina o ka mauna i luna e alakaʻi i nā kumukūʻai hoʻonui.E hoʻohana nui ʻia ke kaʻina hana COB i ka P1.2 a ma lalo o nā huahana pitch.
ʻO ia ma muli o nā pono a me nā hemahema o ka COB encapsulation liʻiliʻi pixel pitch LED hōʻike: 1. ʻAʻole ʻo COB ke koho ala mua loa no ka hōʻike LED pitch pitch liʻiliʻi.Ma muli o ka holomua ʻana o ka LED pitch pixel liʻiliʻi mai ka huahana nui-pitch, e loaʻa ʻole iā ia ka ʻenehana makua a me ka hiki ke hana o ke kaʻina hana hoʻouka.Hoʻokumu pū kēia i ke ʻano o nā LED pixel pitch liʻiliʻi i kau ʻia i kēia lā i ka hapa nui o ka mākeke no nā pale LED pitch pitch liʻiliʻi.
2. ʻO COB kahi "ʻano hikiʻole ke pale aku" no ka hōʻike LED pitch pitch liʻiliʻi e hoʻololi hou i nā pitch liʻiliʻi a i nā noi i loko o ka hale kiʻekiʻe.No ka mea, ma nā kiʻekiʻe pixel kiʻekiʻe, ʻo ka wikiwiki o ke kukui make o ke kaʻina o ka mauna i luna e lilo i "pilikia hemahema huahana."Hiki i ka ʻenehana COB ke hoʻomaikaʻi maikaʻi i ka hanana kukui make o ka hōʻike LED pitch pitch liʻiliʻi.I ka manawa like, ma ke kauoha kiʻekiʻe a me ka mākeke kikowaena hoʻouna, ʻo ke kumu o ka hopena hōʻike ʻaʻole ʻo ka "mālamalama" akā ʻo ka "ʻoluʻolu a me ka hilinaʻi" e lanakila ana.ʻO kēia ka pono o ka ʻenehana COB.
No laila, mai ka makahiki 2016, hiki ke noʻonoʻo ʻia ka hoʻomohala wikiwiki ʻana o COB encapsulation liʻiliʻi pixel pitch LED hōʻike e like me ka hui ʻana o ka "pitch liʻiliʻi" a me ka "mākeke kiʻekiʻe".ʻO ka hana makeke o kēia kānāwai, ʻo nā hui pale LED ʻaʻole i komo i ka mākeke o ke kauoha a me nā kikowaena hoʻouna i makemake iki i ka ʻenehana COB;ʻO nā hui pale LED e nānā nui ana i ka mākeke o nā kauoha a me nā kikowaena hoʻouna e makemake nui i ka hoʻomohala ʻana i ka ʻenehana COB.
ʻO ka ʻenehana he pau ʻole, aia ka MicroLED nui ma ke alanui
ʻO ka hoʻololi ʻenehana o nā huahana hōʻike LED ua ʻike i ʻekolu mau ʻāpana: in-line, surface-mount, COB, a me ʻelua kipi.Mai ka laina laina, mauna ʻilikai, a hiki i ka COB ʻo ia ka pitch liʻiliʻi a me ka hoʻonā kiʻekiʻe.ʻO kēia kaʻina evolutionary ka holomua o ka hōʻike LED, a ua hoʻomohala hou aʻe i nā mākeke noi kiʻekiʻe.No laila e hoʻomau ʻia kēia ʻano ʻenehana ʻenehana i ka wā e hiki mai ana?ʻAe ka pane.
ʻO ka pale LED mai ka inline a hiki i ka ʻili o nā hoʻololi, ʻo ke kaʻina hana i hoʻohui ʻia a hoʻololi i nā kikoʻī kikoʻī o nā pahu kukui.ʻO nā pōmaikaʻi o kēia hoʻololi, ʻo ia ka mea hiki ke hoʻohui i luna.LED pale ma ka liʻiliʻi pixel pitch pae, mai ka ili-mauna kaʻina kaʻina i ka COB kaʻina hoʻololi, i ka hoʻohui i ka hoʻohui kaʻina hana a me ka pūʻolo kiko'ī hoʻololi, COB hoʻohui a me ka encapsulation hoʻohui kaʻina kaʻina hana o ka holoʻokoʻa oihana kaulahao re-segmentation.I ka manawa like, ʻaʻole lawe wale ke kaʻina COB i ka hiki ke hoʻokele pitch liʻiliʻi, akā lawe pū kekahi i ka hōʻoluʻolu ʻike maikaʻi a me ka ʻike hilinaʻi.
I kēia manawa, ua lilo ka ʻenehana MicroLED i mea ʻē aʻe o ka noiʻi ʻana i ka nānā ʻana i mua.Ke hoʻohālikelike ʻia me kāna kaʻina hana COB ma mua o nā LED pixel pitch liʻiliʻi, ʻaʻole hoʻololi ka manaʻo MicroLED i ka hoʻohui ʻana a i ʻole encapsulation ʻenehana, akā hoʻoikaika i ka "miniaturization" o nā kristal bead kukui.
I loko o ka ultra-high pixel density liʻiliʻi pixel pitch LED pale huahana, aia ʻelua mau koi ʻenehana kūʻokoʻa: ʻO ka mua, kiʻekiʻe pika kiʻekiʻe, pono ia i kahi kukui liʻiliʻi.Hoʻopili pololei ka ʻenehana COB i nā ʻāpana aniani.Hoʻohālikelike ʻia me ka ʻenehana mauna o luna, ua kūʻai ʻia nā huahana bead kukui i hoʻopaʻa ʻia.Ma keʻano maoli, loaʻa iā lākou ka pōmaikaʻi o nā ana geometric.ʻO kēia kekahi o nā kumu i kūpono ai ʻo COB no nā huahana pale LED pitch liʻiliʻi.ʻO ka lua, ʻo ke kiʻekiʻe kiʻekiʻe o ka pixel density ʻo ia hoʻi e hoʻemi ʻia ka pae ʻālohilohi o kēlā me kēia pika.Ultra-liʻiliʻi pixel pitch LED pale, ka hapanui hoʻohana 'ia no ka hale a kokoke i ka nana ana mamao, i ko lakou mau koi pono no ka olinolino, i emi mai na tausani o ka lumens ma waho pale a emi ma mua o hoʻokahi tausani, a hiki i haneri o lumens.Eia kekahi, ʻo ka hoʻonui ʻana i ka helu o nā pika i kēlā me kēia ʻāpana, e hāʻule ka ʻimi ʻana i ka ʻōlinolino o kahi aniani hoʻokahi.
ʻO ka hoʻohana ʻana i ka micro-crystal structure o MicroLED, ʻo ia hoʻi e hālāwai me ka geometry liʻiliʻi (i nā noi maʻamau, ʻo ka nui o ka aniani MicroLED hiki ke hoʻokahi a hoʻokahi ʻumi-kausani o ka pae kukui liʻiliʻi liʻiliʻi pixel pitch LED i kēia manawa), e hui pū i nā ʻano o lalo. nā ʻāpana aniani ʻōlinolino me nā koi kiʻekiʻe kiʻekiʻe.I ka manawa like, ʻo ke kumukūʻai o ka hōʻike LED ka nui o nā ʻāpana ʻelua: ke kaʻina hana a me ka substrate.ʻO ka hōʻike LED microcrystalline liʻiliʻi ʻoi aku ka liʻiliʻi o ka hoʻohana waiwai substrate.A i ʻole, inā hiki ke hoʻopiha ʻia ke ʻano pixel o kahi kiʻi alakaʻi pixel pitch liʻiliʻi i ka manawa like e nā kristal LED nui a me ka liʻiliʻi liʻiliʻi, ʻo ka hoʻohana ʻana i ke kumu kūʻai haʻahaʻa.
Ma ka hōʻuluʻulu manaʻo, ʻo nā pōmaikaʻi pololei o MicroLEDs no nā kiʻi liʻiliʻi pixel pitch LED nui he haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa, hana kiʻekiʻe hina, a me ka geometry liʻiliʻi.
Ma ka manawa like, loaʻa i nā MicroLED kekahi mau pono hou no nā pale LED pitch pitch liʻiliʻi.Hiki ke hoʻohana ʻia kēlā ʻano kikoʻī pixel pitch LED i nā mea a me nā ʻenehana hoʻomaʻamaʻa māmā ma kahi ākea ākea e hoʻomaikaʻi i nā hopena ʻeleʻele a me ka ʻeleʻele hina o ka pale LED.2. ʻO nā ʻāpana aniani liʻiliʻi e waiho i kahi lumi hou no ke kino pale LED.Hiki ke hoʻonohonoho ʻia kēia mau wahi hoʻolālā me nā ʻāpana sensor ʻē aʻe, nā hale optical, nā hale hoʻoheheʻe wela, a me nā mea like.3. ʻO ka hōʻike LED pitch pitch liʻiliʻi o ka ʻenehana MicroLED e hoʻoili i ke kaʻina hana encapsulation COB ma ke ʻano holoʻokoʻa a loaʻa iā ia nā pono āpau o nā huahana ʻenehana COB.
ʻOiaʻiʻo, ʻaʻohe ʻenehana kūpono.ʻAʻole ʻokoʻa ka MicroLED.Ke hoʻohālikelike ʻia me ka hōʻike LED pitch pitch liʻiliʻi maʻamau a me ka hōʻike LED COB-encapsulation maʻamau, ʻo ka hemahema nui o MicroLED ʻo ia ka "kahi hana encapsulation hou aʻe."Kapa ka ʻoihana i kēia "he nui o ka ʻenehana hoʻoili."ʻO ia hoʻi, ʻaʻole hiki ke hoʻopau ʻia nā miliona o nā kristal LED ma kahi wafer, a me ka hana aniani hoʻokahi ma hope o ka hoʻokaʻawale ʻana, ʻaʻole hiki ke hoʻopau ʻia ma ke ʻano mechanical maʻalahi, akā makemake i nā mea hana a me nā kaʻina hana.
ʻO ka hope ka "ʻaʻohe bottleneck" i ka ʻoihana MicroLED o kēia manawa.Eia naʻe, ʻaʻole e like me ka ultra-fine, ultra-high-density MicroLED hōʻike i hoʻohana ʻia ma VR a i ʻole nā kelepona kelepona paʻa, hoʻohana mua ʻia nā MicroLED no nā hōʻike LED nui-pitch me ka ʻole o ka palena "pixel density".ʻO kahi laʻana, ʻo ka pixel space o P1.2 a i ʻole P0.5 pae he huahana i ʻoi aku ka maʻalahi o ka "hoʻokō" no ka ʻenehana "hoʻoili nui".
I ka pane ʻana i ka pilikia o ka nui o ka ʻenehana hoʻololi, ua hoʻokumu ka hui ʻoihana o Taiwan i kahi hopena kuʻikahi, ʻo ia hoʻi he 2.5 mau hanauna o nā kiʻi LED pitch pitch liʻiliʻi: MiniLED.ʻOi aku ka nui o nā ʻāpana aniani MiniLED ma mua o ka MicroLED kuʻuna, akā hoʻokahi wale nō hapaʻumi o nā pahu aniani LED maʻamau maʻamau, a i ʻole he mau ʻumi.Me kēia huahana MiNILED i hoʻemi ʻia i ka ʻenehana, manaʻo ʻo Innotec e hiki iā ia ke hoʻokō i ka "hoʻomaʻamaʻa kaʻina hana" a me ka hana nui ma 1-2 mau makahiki.
Ma ke ʻano holoʻokoʻa, hoʻohana ʻia ka ʻenehana MicroLED i ka pixel pitch LED liʻiliʻi a me ka mākeke pale nui, hiki ke hana i kahi "hana maikaʻi loa" o ka hana hōʻike, ʻokoʻa, nā kala kala, a me nā pae hoʻōla ikehu i ʻoi aku ma mua o nā huahana i loaʻa.Eia nō naʻe, mai ka piʻi ʻana i luna a hiki i COB a i MicroLED, e hoʻonui ʻia ka ʻoihana LED pitch pitch liʻiliʻi mai kēlā hanauna a i kēia hanauna, a pono nō hoʻi ia e hoʻomau i ka hana ʻenehana.

ʻO nā huahana pale LED mai ka laina, ka ʻili a hiki i ka COB, kona hoʻomaikaʻi mau ʻana i ke kiʻekiʻe o ka hoʻohui ʻana, ka wā e hiki mai ana o nā huahana MicroLED nui, ʻoi aku ka paʻakikī o ka ʻenehana "hoʻoili nui".
Inā ʻo ke kaʻina hana i loko o ka laina he ʻenehana kumu i hiki ke hoʻopau ʻia e ka lima, a laila ʻo ke kaʻina hana i luna o ka ʻili he hana pono e hana ʻia me ka mechanically, a pono e hoʻopau ʻia ka ʻenehana COB i kahi maʻemaʻe maʻemaʻe, kahi automated piha, a ʻōnaehana helu helu.ʻO ke kaʻina hana MicroLED e hiki mai ana ʻaʻole wale nā hiʻohiʻona a pau o ka COB, akā hoʻolālā pū kekahi i ka nui o nā hana hoʻoili uila "minimal".Hoʻonui hou ʻia ka paʻakikī, e pili ana i ka ʻoihana hana semiconductor paʻakikī.
I kēia manawa, ʻo ka nui o ka ʻenehana hoʻololi a MicroLED e hōʻike nei i ka nānā a me ka noiʻi a me ka hoʻomohala ʻana o nā kanaka nunui honua e like me Apple, Sony, AUO a me Samsung.Loaʻa iā Apple kahi hōʻike hōʻike o nā huahana hōʻike hiki ke hoʻohana ʻia, a ua hoʻokō ʻo Sony i ka hana nui o P1.2 pitch splicing LED nui pale.ʻO ka pahuhopu o ka hui Taiwanese ʻo ia ka hoʻolaha ʻana i ka ulu ʻana o ka nui o ka ʻenehana hoʻololi a lilo i mea hoʻokūkū o nā huahana hōʻike OLED.
I kēia holomua holomua o nā pale LED, ʻo ke ʻano o ka hoʻonui ʻana i ka paʻakikī kaʻina hana i kona mau pono: no ka laʻana, ka hoʻonui ʻana i ka paepae ʻoihana, ka pale ʻana i nā mea hoʻokūkū kumu kumu ʻole, ka hoʻonui ʻana i ka ʻoihana, a me ka hana ʻana i nā ʻoihana ʻoihana "hoʻokūkū".ʻO nā pōmaikaʻi "hoʻoikaika nui a hana i nā huahana ʻoi aku ka maikaʻi.Eia nō naʻe, ʻo kēia ʻano hoʻomaikaʻi ʻana i ka ʻoihana kekahi i kona hemahema.ʻO ia hoʻi, ʻoi aku ka kiʻekiʻe o ka paepae no nā hanauna hou o ka hoʻonui ʻana i ka ʻenehana, ka paepae no ke kālā, ʻoi aku ka kiʻekiʻe o ka paepae no ka noiʻi a me ka hoʻomohala ʻana, ʻoi aku ka lōʻihi o ka pōʻai no ka hoʻokumu ʻana i nā pono popularization, a ua hoʻonui nui ʻia ka pilikia hoʻopukapuka.ʻO nā hoʻololi hope e ʻoi aku ka maikaʻi o ka monopoli o nā pilikua honua ma mua o ka hoʻomohala ʻana i nā ʻoihana hou kūloko.
ʻO nā mea a pau e like me ka huahana LED pitch pitch liʻiliʻi hope loa, pono ke kali ʻana i nā holomua ʻenehana hou.Nui nā ʻenehana i hiki ke paʻi ʻia i nā waiwai ʻenehana o ka ʻoihana LED: ʻaʻole COB wale nō akā ʻo ka ʻenehana flip-chip;ʻAʻole hiki i nā MicroLED ke lilo i mau kristal QLED a i ʻole nā mea ʻē aʻe.
I ka pōkole, ʻo ka pixel pitch LED ʻoihana pale nui kahi ʻoihana e hoʻomau i ka hana hou a me ka holomua ʻenehana.
