ʻO MicroLED, i manaʻoʻia e ka poʻe he nui ka hanauna hou o ka ʻenehana hōʻike, ua alualu ʻia e nā mea pāʻani o LED, hōʻike, OEM, nā mea a me nā mea ʻē aʻe. Hoʻokaʻawale ʻia mai LCD a me OLED, ua manaʻo ʻia ʻo microLED ʻo ia wale nō ka ʻenehana hōʻikeʻike ʻaʻohe palena nui. He aha nā mea hiki ke noi? He aha nā hypes a me nā mea maoli? He mau nīnau kēia i kamaʻilio ʻia ma ka hōʻike IDTechEx hou, " Nā Hōʻike Micro-LED 2020-2030: ʻenehana, Commercialization, Opportunity, Market and Players".
Ke alakaʻi nei nā ʻano hoʻoikaika like ʻole i ka holomua o nā hōʻike MicroLED
Ua hoʻolaha ʻo Samsung Display e hoʻopau ana i ka ʻoihana LCD a e kālele ana i kāna ʻoihana QD LCD & OLED. Ua hooki ʻo LG Display i kāna hana ʻana i nā pā LCD. Kūleʻa nā mea kūʻai Korea e hōʻemi i kā lākou LCD panel hana a hoʻololi i QLED & OLED. Eia kekahi, ke hele nei ʻo Panasonic a me JDI mai ka ʻoihana LCD. ʻO AUO, Innolux a me kekahi mau hui ʻē aʻe o Taiwan e lohi nei i ka hoʻopukapuka ʻana ma LCD a i ʻole OLED. E like me ka hoʻohālikelike ʻana, ke neʻe nei ka hana LCD i ka ʻāina ʻo Kina ma muli o ka mākaukau kumu kūʻai, ka pono hana laina hou a me ke kākoʻo kaulahao ʻoihana.
Ma ka ʻāpana OLED, ua hoʻomalu ʻia ka hana ʻana o ka panel OLED e nā hui Korea e pili ana i ka hiki ke hana pono, nā mea hana a me nā mea hana, ka noi lalo, a me ka hoʻopiha piha ʻana i ke kaulahao. No ka laʻana, ua kākoʻo ʻo SDC a me LGD i nā ʻoihana waiwai a me nā lako hana, kūkulu i nā kaiaola maikaʻi. No nā noi haʻahaʻa, hāʻawi mua ʻia nā panela OLED liʻiliʻi a waena o Samsung i nā kelepona akamai Samsung, ʻoiai hāʻawi mua ʻia nā panela OLED nui o LGD i nā TV LG. Hiki i kā lākou mau hōʻailona ke hāʻawi i ke kākoʻo a me ka manaʻo. Ke hoʻomalu nei ʻo Samsung a me LG i nā panela OLED liʻiliʻi / waena a me ka nui.
E pili ana i nā mea waiwai a me nā lako o luna, ikaika loa ʻo Iapana a me Kelemania. Hiki ke hoʻohana ʻia kā lākou mau pono i ka LCD a i ʻole OLED wale nō, akā i nā ʻano hōʻike hōʻike hou ʻē aʻe kekahi.
Me kēia kāʻei kua, hiki i ke komo ʻana i kahi ʻenehana hōʻike hou ke lawe mai i nā manawa hou i nā mea pāʻani kūpono, no ka mea hiki i kahi ʻenehana hōʻikeʻike hou ke wāwahi i nā pūʻulu kūloko a me nā pono o kēia manawa, e hana ana i kahi ʻano ʻoihana hou.
ʻO kēia kekahi o nā kumu koʻikoʻi i makemake nui ai nā hōʻike microLED. Eia kekahi, hāʻawi nā hōʻike microLED i nā manaʻo waiwai e like me ka gamut kala ākea, ka luminance kiʻekiʻe, ka hoʻohana haʻahaʻa haʻahaʻa, ke kūpaʻa maikaʻi loa a me ka lōʻihi o ke ola, ke kihi ākea ākea, ka laulā kiʻekiʻe kiʻekiʻe, ka ʻokoʻa kiʻekiʻe, ka wikiwiki hoʻomaha wikiwiki, ka ʻike, ka pilina pili ʻole, a me ka hoʻohui sensor. hiki, a pēlā aku. Hiki ke hāʻawi ʻia kekahi o nā manaʻo waiwai e nā mea ʻē aʻe e like me LCD, OLED a me QD, ʻoiai aia ka microLED i kāna mau kumu waiwai kūʻokoʻa i hahai ʻia e nā mea he nui.
Nā manaʻo waiwai o nā ʻenehana hōʻike like ʻole. Puna: IDTechEx
ʻO kekahi mea hoʻokele ka piʻi nui o nā mea pāʻani e hahai ana i ka ʻoihana microLED. ʻAʻole paha ʻo MicroLED ko lākou manaʻo nui i kēia manawa, akā mālama lākou i kahi ala kokoke iā ia, inā i ka wā e hemo maoli ai ka microLED, hiki iā lākou ke hopu koke, ma kahi o ka waiho ʻana.
Hoʻonui i nā hana me nā manaʻo hoʻomohala hoʻololi
Hiki ke ʻike ʻia ka piʻi ʻana o ka nui o nā hana mai nā mea hoʻolako hōʻike mai ka hoʻopukapuka nui ʻana o ~ $5 biliona, ka piʻi nui ʻana o ka waiho ʻana i nā patent, a me nā prototypes / huahana i lawe ʻia e nā mea kūʻai aku microLED. Hiki iā mākou ke ʻike i nā inoa e like me AUO, PlayNitride, RiTdisplay, Samsung, LG, Sony, TCL, Tianma, Konka, Glo, Plessey, JBD, X-Display, VueReal, CSOT, Sharp, Kyocera, etc.
Eia nō naʻe, ʻokoʻa loa nā prototypes e hōʻoia i ka mākaukau ʻenehana/ʻepekema me ka hana lab/fab scale mai nā huahana kālepa i hana nui ʻia. Pono ka hope i nā kīnā ʻole no nā huahana mea kūʻai aku. ʻOiai ua hōʻoia ʻia ka ʻepekema ma laila, ʻoi aku ka paʻakikī o ka ʻenehana a me nā pilikia hana. No ka laʻana, hiki i nā LED maʻamau ke hiki i ka quantum efficiencies o waho (EQEs) i ~ 70%, aʻo nā microLED liʻiliʻi ma lalo o 10 µm hiki ke paʻakikī a hiki i 20%. He mea paʻakikī loa nā LED ʻulaʻula me nā EQE haʻahaʻa a me nā hiʻohiʻona brittle. ʻO nā microLED liʻiliʻi he ʻāpana ākea nui, hiki ke alakaʻi i nā hemahema hou aʻe i ka wā o ke kaʻina hana. No laila, he mea koʻikoʻi ka hoʻoponopono ʻana i nā pilikia ʻenekinia/hana, me ka hoʻonui ʻana i ka nui o ka make me ka mālama ʻana i ka hana kiʻekiʻe, ka hoʻolālā chip a me ka hoʻomaikaʻi ʻana i ka ʻenehana hana chip. ʻO nā pilikia ʻē aʻe e pili ana i ka nui o ka hoʻoili ʻana, ka hoʻoponopono defect, ka hoʻāʻo ʻana, ka like ʻole, ka hoʻololi ʻana i ka kala, etc.
No ka hana ʻana i kahi hōʻike microLED, nui nā ʻenehana a me nā kaʻina hana, e like me epitaxy, photolithography, chip fabrication, substrate removal, inspection, mass transfer, bonding and interconnection, testing, repair, backplane and drive IC, etc. Ma hope o nā makahiki o ka hoʻomohala ʻana, ua hoʻoholo ʻia kekahi mau pilikia ʻenehana, ʻoiai ke kau ʻia nei nā pilikia hou i mua o mākou. No ka laʻana, i kekahi mau makahiki i hala aku nei, ua hoʻopaʻa ʻia nā hana nui i ka die miniaturization, ka hoʻolālā chip a me ka hoʻoili nui ʻana, etc. No laila, ʻoi aku ka nui o ka poʻe e hoʻoikaika i nā ʻenehana e like me ka nānā ʻana, hoʻoponopono, hoʻokele, hoʻomaikaʻi kiʻi, hoʻokele māmā, a me nā lako hana kiʻekiʻe.
Hoʻololi hou i ka lako ma lalo o COVID-19
ʻO kekahi o nā kūkākūkā nui loa e kū nei ma ka honua i kēia manawa ʻo COVID-19. Me ka nui o nā ʻāina i loaʻa iā COVID-19 ma lalo o ka mana, ʻaʻole wale ka nīnau no ke olakino lehulehu, akā ʻo nā hopena lōʻihi hoʻi i hoʻolei ʻia mai iā mākou i ka pilikanaka, ka waiwai, a me ka politika.
Hoʻopili i nā ʻoihana he nui a me nā ʻoihana hou, hiki i nā hōʻike micoLED ke hoʻohālike i ka LED e kū nei a hōʻike i ke kaulahao lako, e hopena i kahi mea hou a paʻakikī. Hiki i nā ʻenehana hou a me nā huahana hou ke hāʻawi i nā manawa hou no ka poʻe pāʻani, e like me ka ʻoihana CMOS hiki ke kū i kahi kūlana ma ka microLED-based micro-display supply chain.
ʻIke ʻia me COVID-19, hiki ke hoʻololi ʻia ka hoʻokele waiwai honua a me ka hale kaulahao.
ʻOkoʻa loa nā manaʻo o COVID-19 i Pepeluali a ma hope. I Pepeluali, ʻo ke kūlana o COVID-19 ka mea koʻikoʻi loa ma Kina. No laila, nui nā loiloi i kālele ʻia i ka palekana kaulahao lako. Ua kūkākūkā pinepine ʻia ka pilikia e hilinaʻi hou i nā kaulahao lako ʻoihana honua ma Kina. ʻOiai mai Malaki, ua ʻike ka maʻi maʻi honua i ka poʻe mai kahi kihi ākea. ʻO ka mea mua, ua hoʻohaʻahaʻa nui ʻia ka ulu ʻana o ka hoʻokele waiwai honua a puni ka honua a ua piʻi aʻe ka helu hana ʻole, ʻoiai me ke kākoʻo aupuni mai kekahi mau ʻāina. ʻO ka lua, ua hoʻopilikia nui ʻia ka ʻoihana kūʻai. E hōʻemi ʻia ke kūʻai ʻana i nā huahana liʻiliʻi no nā mea kūʻai aku a me nā ʻoihana ʻoihana. ʻO ke kolu, ua hoʻopilikia ʻia nā mākeke kālā. ʻO ka mea aʻe, akā ʻaʻole ka mea liʻiliʻi, e mau ana ka hopena i ke kaulahao lako honua, no kēia manawa a i ka wā e hiki mai ana.
Ua ʻae ʻia e ka poʻe he nui ka maʻi maʻi honua COVID-19 e hoʻoikaika i ka pilina o US-China. Eia kekahi, ke emi nei ka honua me nā palena paʻa, nā palena huakaʻi, nā kūlana hoʻokuʻu aku a me nā kaulahao lako. Ma kekahiʻaoʻao, ua loheʻo IDTechEx mai kekahi mau hui liʻiliʻi a lākou i koho koho ai e hui pū me nā hui i emiʻole ka hopena o ke kaua kālepa. Ma ka ʻaoʻao ʻē aʻe, ʻoiai ʻo ke ao holoʻokoʻa ke ʻano maʻamau, ʻoi aku ka koʻikoʻi o nā puʻupuʻu āpana i ke kūkulu ʻana i ke kaulahao ma mua o ka pūnaewele puni honua i ka wā e hiki mai ana.

Nā Mākeke noi no nā hōʻike MicroLED
Hiki ke nānā ʻia ke koi no nā hōʻike microLED mai ʻelua ʻano:
• Hoʻololi i ka mākeke hōʻike e kū nei
• Ke hana ʻana i kahi mākeke hōʻike hou.
No nā mea mua, 8 mau noi i hōʻike ʻia ma lalo nei e kamaʻilio nui ʻia. ʻO lākou ka mea i hoʻonui ʻia/mixed reality (AR/MR), virtual reality (VR), nā hōʻike wikiō nui, nā TV a me nā mākaʻikaʻi, nā hōʻike kaʻa, nā kelepona paʻalima, nā wati akamai a me nā mea hiki ke hoʻohana ʻia, nā papa a me nā kamepiula.
Hoʻololi i nā mākeke noi e kū nei
No ka laʻana, hoʻohana ʻia nā hōʻike LCD, ka mea i hoʻomalu i ka mākeke hōʻike o kēia manawa, ma kahi kokoke i nā hōʻike āpau ma lalo o 65″. Loaʻa i nā LCD ko lākou palena koʻikoʻi e hele i ka nui nui. Ke hoʻonui nei ʻo OLED i ka māhele mākeke ma nā hōʻike kelepona akamai. Kūʻai ʻia nā QD-LCD ma ke ʻano he TV premium a ʻae ʻia e ka nui o nā mea kūʻai aku. Ua hoʻohana mua ʻia nā hōʻike LED i nā hōʻike lehulehu. No ka hoʻokūkū me lākou, pono ka microLED e hoʻomaopopo i kā lākou mau manaʻo waiwai kūʻokoʻa a i ʻole ka hui pū ʻana o ka waiwai e hāʻawi i nā pono.
Ma ka ʻaoʻao ʻē aʻe, ʻo ka mea hiki ke hāʻawi ʻia i kēia pae e hoʻonohonoho i ka palena. No ka laʻana, i mea e hoʻokūkū koʻikoʻi, pono e hana ʻia nā microLED i nā liʻiliʻi liʻiliʻi. Eia nō naʻe, ʻoi aku ka haʻahaʻa o nā microLED liʻiliʻi ma mua o nā LED kuʻuna i hoʻohana ʻia no ke kukui kūlana paʻa. ʻAʻole hiki i nā microLED haʻahaʻa haʻahaʻa ke hāʻawi i ka manaʻo waiwai "ka hoʻohana haʻahaʻa haʻahaʻa" no nā noi e koi ana i nā LED liʻiliʻi a me ka hoʻohana haʻahaʻa haʻahaʻa.
Ma ke ʻano o ke kumukūʻai, pili ke kumukūʻai o ka mokulele mua o kahi hōʻike microLED maʻamau i ka helu o nā LED, ma kahi o ka ʻāpana, ʻokoʻa ia mai OLED a me LCD. ʻO kēia ke kumu o ka hana ʻana i ke kelepona akamai me ka hoʻonā like ʻana o kahi TV hiki ke hopena i ke kumukūʻai like ʻole, ma mua o nā kauoha o ka manaʻo haʻahaʻa haʻahaʻa.
No laila, he mea koʻikoʻi ka hoʻomaopopo ʻana i nā ala ʻenehana like ʻole ma hope o kēlā me kēia noi a loaʻa i nā loiloi maopopo i ko lākou hiki a me nā manawa kūpono.
No ka hana ʻana i kahi mākeke hōʻike hou e pono ai nā hiʻohiʻona hiki ʻole ke hoʻohana ʻia e nā mea ʻē aʻe. ʻO nā hiʻohiʻona maʻamau e pili ana i nā hōʻike me ke ʻano pilikino a me nā hōʻike me ka hoʻohui ʻana i ka sensor. ʻO nā hōʻikeʻike hou e puka mai nei e hoʻonui i ko mākou noʻonoʻo ma mua o nā hōʻike i loaʻa a kōkua i ka hele ʻana i ka honua me nā hōʻike ubiquitous.
