I kēia mau lā, ua hoʻokuʻu ka ʻāpana B2B o kahi hui hōʻailona nui i kahi hanauna hou o ka moʻo palapala hōkū ʻo COB liʻiliʻi.ʻO 70μm wale nō ka nui o ka pahu kukui LED o ka huahana, a hoʻomaikaʻi ka ʻāpana pixel liʻiliʻi liʻiliʻi i ka ʻokoʻa.
ʻO kaʻoiaʻiʻo, ke hoʻonui nei nā mea hana nui i kā lākou R&D a me ka hana hou o ka ʻenehana COB a hopu i ka mākeke.Eia nō naʻe, ma kahi o ka ʻae ʻana ʻo "COB ke alakaʻi kiʻekiʻe kiʻekiʻe o ka ʻenehana packaging", aia nō nā ʻokoʻa nui i ka ʻenehana MiP a me COB i loko o ka ʻoihana.
ʻO ka hoʻoholo ʻana i nā ala ʻenehana lōʻihi a pōkole
Ke hoʻonui nei ʻo COB i nā pitch nui a neʻe ʻo MiP i nā pitch liʻiliʻi, e ʻike ʻole ʻia kahi pae o ka hoʻokūkū ma waena o nā ala ʻenehana ʻelua.Akā i kēia manawa, ʻaʻole ia he pilina ola a make paha.No laila, i loko o kekahi manawa a i loko o kahi mamao, COB, MiP, a me IMD e noho pū kekahi me kekahi.ʻO kēia nā kaʻina hana pono no ka hoʻomohala ʻenehana.
Mai kahi hiʻohiʻona lōʻihi, ua hoʻokumu ʻo COB i kahi pōmaikaʻi nui o ka neʻe mua, a ua komo piha nā hui a me nā hōʻailona i ka mākeke;Eia kekahi, loaʻa iā COB nā ʻano kūlohelohe o nā loulou kaʻina hana pōkole a maʻalahi;ke kaʻina hana hoʻoili lehulehu Ma hope o ka loaʻa ʻana o kahi holomua ma ke ʻano o ke kumukūʻai a me ke kumukūʻai, aia ka hiki ke lanakila i nā kūlanakauhale a me nā ʻāina.
Ma ka mākeke o kēia manawa, hoʻohana nā pale nui kiʻekiʻe i nā huahana LED me ka liʻiliʻi liʻiliʻi (ma lalo o P2.5).I ka wā e hiki mai ana, e hoʻomau ia i ka hoʻomohala ʻana i ke kiʻekiʻe o ka pixel kiʻekiʻe a me ka pitch pixel liʻiliʻi, e hāpai i ka COB i lilo i alakaʻi koʻikoʻi no ka hoʻomaikaʻi ʻana a me ka hoʻoponopono hou ʻana o ka ʻenehana hōkeo LED.
ʻO ke kūlana hoʻomohala COB a me nā hiʻohiʻona
Wahi a ka ʻikepili mai kahi hui ʻike mana, i ka hapa mua o 2023, kūʻai aku i nā hōʻike LED liʻiliʻi ma ka ʻāina nui ʻo Kina i 7.33 biliona, he piʻi iki o 0.1% makahiki-ma-makahiki;ka moku hoʻouna i hiki i 498,000 square mika, he makahiki-ma-makahiki piʻi o 20.2%.I waena o lākou, ʻoiai ʻo SMD (me ka IMD) ʻenehana ka mea nui, ke hoʻomau nei ka ʻāpana o ka ʻenehana COB.Ma ka hapaha ʻelua o 2023, ua hōʻea ka hapa o ke kūʻai aku i 10.7%.Ua hoʻonui ʻia ka māhele mākeke holoʻokoʻa i ka hapa mua o ka makahiki ma kahi o 3 mau pākēneka i hoʻohālikelike ʻia me ka manawa like.
I kēia manawa, ʻo ka mākeke huahana no ka ʻenehana LED hōʻike liʻiliʻi COB e hōʻike i kēia mau hiʻohiʻona:
Kumukūʻai: Ua emi ke kumu kūʻai o ka mīkini holoʻokoʻa ma lalo o 50,000 yuan/㎡.Ua emi nui ke kumukūʻai o ka ʻenehana hoʻopili COB, no laila ua emi nui ke kumukūʻai makeke o nā huahana COB hōʻike liʻiliʻi liʻiliʻi ma mua o ka wā ma mua.I ka hapa mua o 2023, ua hāʻule ke kumu kūʻai o ka mākeke ma 28%, a hiki i ke kumu kūʻai awelika o 45,000 yuan/㎡.
Spacing: E noʻonoʻo i ka P1.2 a ma lalo o nā huahana.Ke emi ka pitch pitch ma mua o P1.2, loaʻa i ka ʻenehana hoʻopihapiha COB kahi mea maikaʻi i ka uku hana holoʻokoʻa;Loaʻa ka COB ma mua o 60% o nā huahana me nā pitches o P1.2 a ma lalo.
Noi: ka nānā ʻana i nā hiʻohiʻona, pono nui i nā ʻoihana ʻoihana.ʻO ka hōʻike LED liʻiliʻi o ka ʻenehana COB nā hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe o ka mālamalama, a me ka wehewehe kiʻekiʻe.I ka nānā ʻana i nā hiʻohiʻona, ʻoi aku ka nui o nā hoʻouna COB ma mua o 40%;Hoʻokumu nui ʻia lākou i nā pono o nā mea kūʻai aku ma nā ʻoihana ʻoihana, me ka ikehu kikohoʻe, ka lawe ʻana, ka pūʻali koa, ke kālā a me nā ʻoihana ʻē aʻe.
Ka wānana: Ma ka 2028, e helu ʻo COB ma mua o 30% o nā LED liʻiliʻi liʻiliʻi.
Hōʻike ka hōʻike hōʻike ʻana i ka hana ʻana o ka ʻenehana hoʻopihapiha COB i kahi pilina maikaʻi i ʻekolu mau ʻano: ka holomua ʻenehana ʻenehana, ka hoʻonui ʻana i ka hiki a me ka hoʻonui ʻana i ka mākeke, e lilo ia i mea koʻikoʻi ʻenehana huahana i ka hoʻomohala ʻana i ka micro-pitch i ka LED liʻiliʻi. ʻoihana hōʻike.
Ma ka makahiki 2028, ʻoi aku ka nui o ka ʻenehana COB ma mua o 30% o ke kūʻai aku ma ka mākeke hōʻike liʻiliʻi o Kina (ma lalo o P2.5).
Mai kahi hiʻohiʻona ʻoihana, ʻo ka hapa nui o nā ʻoihana e pili ana i ka hōʻike LED ʻaʻole i kālele i hoʻokahi ala.Ke holomua nei lākou ma nā kuhikuhi COB a me MiP.Eia kekahi, ma ke ʻano he ʻoihana hoʻopukapuka waiwai a me ka ʻenehana-intensive, ʻaʻole i hahai pono ka ulu ʻana o ka ʻoihana hōʻike LED i ke kumu hana mua o "ke kālā maikaʻi i ke kālā maikaʻi ʻole".Hiki i ka manaʻo a me ka ikaika o ka pūʻulu hui ke hoʻopili i ka wā e hiki mai ana ʻelua.
