Me ka hoʻomau mau ʻana o MicroHōʻike LED, nui nā holomua i hana ʻia ma ka ʻenehana.I kēia mau lā, ua loaʻa pinepine nā hanana hou i nā hōʻike Micro LED, a ua nui nā hanana ʻenehana hou i ka honua.
Hoʻokumu ʻo Yonsei University i ka ʻenehana hōʻike Micro LED tri-color kiʻekiʻe
Ua hōʻike ʻia ua hoʻohana ka hui o Polofesa Jong-hyun Ahn o ke Keʻena ʻenehana a me Electronic Engineering o Yonsei University i nā semiconductors MoS2 a me nā kiko quantum e hoʻokō i ka ʻenehana hōʻike kiʻekiʻe tri-color Micro LED. ʻO ka ʻenehana, i paʻi ʻia ma "Nature Nanotechnology. , "a ʻo ia ka mea mua o ka honua e hoʻomohala i kahi ʻenehana hoʻohui me ka hoʻohana ʻana i nā semiconductors ʻelua-dimensional a me nā kiko quantum, i manaʻo ʻia e hoʻohana ʻia i ka hoʻomohala ʻana i nā hōʻike hōʻike kiʻekiʻe-hana kiʻekiʻe (AR) a me ka virtual reality (VR).He nuhou maikai noʻoihana LED.
No ka hana ʻana i kahi hōʻike Micro LED, pono ke kaʻina hana paʻakikī o ka hoʻololi ʻana i nā ʻāpana Micro LED ʻekolu kala i kahi papa kaapuni backplane.ʻOiai ua kūpono kēiaʻano hana hana no ka hanaʻana i nā hōʻike nui me ka haʻahaʻa haʻahaʻa,ʻaʻole hiki iā ia ke hoʻokō i nā koi o ka hanauna hou augmented reality (AR) a me ka virtual reality (VR) hōʻike e koi ana i ka hoʻonā kiʻekiʻe a me ka hana wikiwiki.
No ka lanakila ʻana i nā palena ʻenehana o ka hoʻomohala ʻana i nā hōʻike Micro LED, ua hoʻokumu ka hui noiʻi i ʻelua-dimensional semiconductor molybdenum disulfide (MoS2) pololei ma luna o kahi gallium nitride (GaN) wafer no nā LED polū, a laila hoʻohui i nā kaapuni semiconductor e hana i nā kaapuni semiconductor pākahi. Ua ʻike maikaʻi ʻo ia i ka 500 PPI mua o ka honua (helu o nā kumu kukui LED Micro i kēlā me kēia ʻīniha), hōʻike kiʻekiʻe Micro LED me ka ʻole o ke kaʻina hoʻololi.Eia kekahi, ua hoʻomohala ka hui noiʻi i kahi ʻenehana e hoʻokō ai i ʻekolu mau kala kumu ma ka paʻi ʻana i nā kiko quantum ma nā GaN Micro LED polū, hiki ke hoʻomaikaʻi maikaʻi i ke kaʻina hana a hōʻemi i nā kumukūʻai hana.Eia kekahi, ʻaʻole hiki i ka ʻenehana i hoʻomohala ʻia e ka hui noiʻi ke maʻalahi i ke kaʻina hana paʻakikī o MicroHōʻike nā LED i ka huahana, akā e hoʻokō pū i ka hoʻonā kiʻekiʻe.
Hoʻokumu ʻo Kyung Hee University i nā ʻano optics ultra-dense no nā polokalamu AR
I kēia mau lā, ua hoʻohana kekahi hui noiʻi i alakaʻi ʻia e Professor Lee Seung-hyun o ke Keʻena ʻEnekinia Electronic o Kyung Hee University i hoʻohana i nā diodes ultra-highly integrated micro light-emitting diodes (i kapa ʻia ma hope nei ʻo Micro LEDs) no ka hana ʻana i nā mea hoʻonohonoho optical me nā nui pixel o ka lepo. nā ʻāpana a me nā kiko kiko a me ke kala maikaʻi loa.Hoʻihoʻi hou.Manaʻo ʻia e hoʻohana ʻia nā ʻāpana o nā mea optical e hana i nā kiʻi ʻoiaʻiʻo i hoʻonui ʻia ma ka maka.Paʻakikī ka Fusion ma muli o nā ʻokoʻa i nā substrates hana o nā kaʻa uila a me nā Micro LED.ʻO ka mea maʻamau, hana ʻia nā kaapuni uila ma nā substrates silika, aʻo nā Micro LED i hana ʻia ma nā substrates gallium nitride.No ka hoʻoponopono ʻana i kēia pilikia, ua hoʻomohala ka hui noiʻi o Polofesa Li i kahi ʻenehana e hiki ke hoʻololi i nā ʻāpana lahilahi o ka gallium nitride, ma kahi o hoʻokahi hapaʻumi o ka mānoanoa o ka lauoho kanaka, ma luna o kahi pani silika.
Ma muli o kēia ʻenehana, ua hoʻokumu maikaʻi ka hui noiʻi i ka nui liʻiliʻi liʻiliʻi o ka honua (5μm) LED pixel ma o ka hoʻohana ʻana i ka ʻenehana kaapuni silika wale nō a ʻaʻohe kaʻina hōʻike maʻamau."Hoʻopilikia nui ʻia ka ʻenehana hoʻololi e ka hoʻonui wela, no laila ua kālele mākou i ka hana ʻana i nā ʻāpana hao lahilahi i nā haʻahaʻa haʻahaʻa," i wehewehe ai ka haumāna ʻenekinia uila ʻo Shin Yoo-seop.I ka manawa like, ua hoʻohana ka hui noiʻi i ka ʻenehana quantum dot e hoʻomaikaʻi i ka helu hoʻohua kala, e hoʻohui i kahi manaʻo maoli i ka AR.Ua ʻike nui ʻia nā kiko kuantum e like me nā mea hoʻoheheʻe kukui e hiki mai ana ma muli o ko lākou kiʻekiʻe o ka maʻemaʻe kala a me ka photostability i hoʻohālikelike ʻia me nā mea hoʻoheheʻe kukui maʻamau no ka mea hiki ke hana ʻia ma ka hana ʻana i nā lōʻihi like ʻole o nā hawewe māmā no kēlā me kēia ʻāpana me ka hoʻololi ʻole i ke ʻano.nā mea kala like ʻole.Eia nō naʻe, hiki ke maʻalahi nā kiko quantum i nā solvents like ʻole i hoʻohana ʻia i ka hana semiconductor maʻamau.
No ka hoʻoponopono ʻana i kēia pilikia, ua hoʻomohala ka hui noiʻi i kahi "ʻano hoʻololi maloʻo maloʻo kiʻekiʻe" hiki ke koho koho e like me ka ikaika o ka ikehu.Ua lanakila lākou i ka hoʻohana ʻana i ka ʻenehana quantum dot e hoʻokō i ke kala RGB me ka ʻole o ka solvent.He liʻiliʻi loa nā pika optical i hoʻomohala ʻia ʻoiai ke nānā ʻia ma o ka microscope, e kūpono ana ia no nā mea liʻiliʻi e like me nā mea hiki ke hoʻohana.Eia hou, hiki i ka optical element pixels ke maopopopapahana alakaʻihoʻonui ʻia nā kiʻi ʻoiaʻiʻo ma ka hōʻike ʻana i kahi gamut kala kiʻekiʻe.
