ʻOihana Mini/Micro LED i ka makahiki 2024: He moʻolelo o nā waiwai like ʻole i waena o ka hoʻopukapuka kālā nui (3)

Ke hoʻomau nei nā huahana COB i ka hoʻomalu ʻana i ka mākeke

I ka ʻoihana hōʻike hoʻokūkū kiʻekiʻe, ke holomua nei nā huahana COB. Aia ka manawa o COB i loko LED liʻiliʻi, a ua pili loa kona wā e hiki mai ana i LED liʻiliʻiEia kekahi, i ka wā waena, hiki iā COB ke lawe i ke ʻano o MIP. I ka makahiki 2024, ua puka mai ʻo COB ma ke ʻano he hopena kiʻekiʻe a puni, e hāʻawi ana i kahi "versatility theory" hou.

Ma kekahi ʻaoʻao, ua ʻike ʻia ka emi nui ʻana o ke kumukūʻai o nā pale LED COB i ka makahiki 2024, no laila e ʻimi nei i nā mākeke hou. Hōʻike ka ʻikepili ʻoihana ua hāʻule ke kumukūʻai o nā ʻāpana hoʻopili COB mai 48,000 yuan no ka mika kuea (i helu ʻia ma P1.25) i ka makahiki 2018 a i 9,000 yuan no ka mika kuea i ka makahiki 2024. I ka makahiki 2024, ua emi ke kumukūʻai hapaha he 3 - 5 mau pakeneka. Ua hoʻonui kēia emi ʻana o ke kumukūʻai i ka waihona mea kūʻai aku no nā huahana COB kiʻekiʻe, e hoʻokele pono ana i ka ulu ʻana o ka nui o kāna mākeke.

Ma ka ʻaoʻao ʻē aʻe, ua nui aʻe nā ʻano huahana COB. ʻO ka hoʻonui ʻia o ka lako o nā huahana e like me COB LED liʻiliʻikristal wai nā kukui hope, COB - MIPnā huahana, COB - LED liʻiliʻinā huahana, a me nā huahana COB ma nā kikoʻī P0.7/P1.5/P1.8 ua alakaʻi i ka hoʻonui nui ʻana i nā kūʻai aku ma ka mākeke. ʻAʻole wale kēia i hoʻonui i ka hiki ʻana o ka mākeke o ka ʻenehana COB ma ka ʻoihana hōʻikeʻike akā ua hoʻonui pū i nā ʻano a me ka nui o nā mea kūʻai aku, e wikiwiki ana i ka hoʻomohala ʻana o COB.

Me ka piʻi ʻana o ke koi no nā huahana COB, ke hoʻonui nei nā mea hana ʻoihana i ka hiki ke hana. No ka laʻana, ʻo ka hiki ke hana COB o Zhaochi Co., Ltd. ua emi ma mua o 10,000 mika kuea i ka makahiki 2022, akā i ʻOkakopa 2024, ua piʻi aʻe i 20,000 mika kuea. Ua piʻi nui pū ka hiki ke hana COB o Unilumin Technology i 4000KK/mahina i ka makahiki 2024. Ua wānana ʻo Kauka Shao Pengrui, ke hope luna nui o Asmade Zhuoxing Semiconductor, i ka makahiki 2028, e hiki aku ka wahi hiki ke hana makahiki o COB i 500,000 mika kuea, 7 - 8 mau manawa o ka pae o kēia manawa.

E pili ana i ka hoʻomohala ʻenehana o COB, manaʻoʻiʻo ka ʻoihana he nui ka hoʻoili ʻana a LED liʻiliʻiʻelua mau ʻenehana kākoʻo koʻikoʻi. ʻO ka ulu ʻana o nā mākeke micro-pitch a me ultra-micro-pitch, me ka hoʻonui ʻana o nā hōʻike LED liʻiliʻi maʻamau i nā koi kiʻekiʻe a me nā koi wehewehe ultra-kiʻekiʻe, ʻo ia nā mana hoʻokele nui ma ka ʻaoʻao o ka mea kūʻai. Ma muli o kēia kūlana, ʻaʻohe kumu e hoʻohaʻahaʻa ai i ka ʻenehana COB i ka wā MIP. Eia kekahi, nā huahana MIP ultra - micro - pitchhiki ke hoʻohana i ka hopena hoʻopili lua COB.

Ma lalo o ke kumumanaʻo "ʻo ke kiʻekiʻe - ʻoi aku ka maikaʻi, ʻoi aku ka hilinaʻi ʻana i nā LED liʻiliʻia me nā mea hana micro - kumu i ka nui o ke koi o ka mākeke, ʻo ka COB kaulana loa, e hoʻomau ʻo COB i ke kumuhana wela nui i ka ʻOihana LED liʻiliʻi/micro.
