Hoʻolauna
Ua lilo nā pale LED i mea nui o ko mākou ola i kēlā me kēia lā, mai nā papa hoʻolaha hoʻolaha a hiki i nā hōʻike televise a me nā pale kelepona. Ua hoʻololi ka hoʻomohala ʻana o nā pale LED i ke ʻano o kā mākou launa ʻana me ka ʻike ʻike. Ma kēia ʻatikala, e ʻimi mākou i ka mōʻaukala hoihoi o nā pale LED, mai ko lākou hoʻomaka haʻahaʻa a hiki i ko lākou kūlana i kēia manawa ma ke ʻano he ʻenehana nui i ka ʻoihana hōʻike.
Hoʻomaka mua
Hiki ke huli ʻia ka mōʻaukala o nā pale LED i ka makahiki 1960 i ka wā i hoʻomohala ʻia ai ka LED hana mua e Nick Holonyak Jr. ma General Electric. Ua hoʻohana mua ʻia kēia mau LED mua ma ke ʻano he mau kukui hōʻailona i nā mea uila ma muli o ko lākou hoʻohana haʻahaʻa haʻahaʻa a me ke ola lōʻihi. Eia nō naʻe, ʻaʻole hiki i ka makahiki 1990 ke hoʻohana ʻia ka ʻenehana LED no nā hōʻike nui.
Ka puka ʻana o nā pale LED
Ua ʻike nā 1990s i ka puka ʻana mai o nā pale LED ma ke ʻano he koho kūpono i nā ʻenehana hōʻike kuʻuna e like me CRT a me LCD. ʻO ka hoʻomohala ʻana o nā kukui kukui kiʻekiʻe a me ka hiki ke hana iā lākou i nā kala like ʻole i hoʻomākaukau i ke ala no ka hoʻohana ʻana i nā pale LED i nā hoʻolaha hoʻolaha waho a me nā hōʻike pāʻani. ʻO ka ikaika o ka ikehu a me ka lōʻihi o nā pale LED i lilo lākou i koho maikaʻi no nā ʻoihana a me nā hui e ʻimi nei i nā hopena kamaʻilio ʻike ʻike.
Nā holomua i ka ʻenehana LED
Ke hoʻomau nei ka ʻenehana LED i ka holomua, ʻoi aku ka maikaʻi a me ka hoʻonā ʻana o nā pale LED. ʻO ka hoʻokomo ʻana i nā LED i kau ʻia ma luna (SMD) i ʻae ʻia no ke kiʻekiʻe o ka pixel kiʻekiʻe a me ka hoʻopiʻi ʻana i ka kala ʻoi aku ka maikaʻi, e alakaʻi ana i ka hoʻohana ākea ʻana o nā pale LED i loko o nā noi i loko e like me nā hōʻailona kūʻai, nā hōʻike hui, a me nā pale hanana. Hoʻohui ʻia, ʻo ka hoʻomohala ʻana i nā hōʻike LED fine-pitch i hiki ke hana i nā paia wikiō seamless me ka mālamalama kiʻi kupaianaha.
Ke piʻi aʻe o LED i ka ʻoihana hōʻike
I nā makahiki i hala iho nei, ua ʻike nā pale LED i ka piʻi ʻana o ka kaulana, me kā lākou mākeke mākeke hiki i ka 5%. Hiki ke hoʻohālikelike ʻia kēia ulu ʻana i nā kumu he nui, me ka emi ʻana o ke kumukūʻai o ka ʻenehana LED, ka piʻi nui ʻana o ka noi no nā hōʻike wehewehe kiʻekiʻe, a me ka versatility o nā pale LED i nā wahi like ʻole. Hoʻohana maʻamau ʻia nā pale LED i nā ʻano hana like ʻole, me ka hōʻailona kikohoʻe, nā hale hoʻolaha hoʻolaha, nā kikowaena kauoha a me ka mana, a me nā pae hana virtual.
Nā ʻano hou a me nā mea hou
Ke nānā nei i mua, ʻike ʻia ka wā e hiki mai ana o nā pale LED, me ka hoʻomau ʻana o ka noiʻi a me ka hoʻomohala ʻana i ka hoʻonui ʻana i kā lākou hana a me nā hiki. ʻO nā mea hou e like me nā hōʻike LED māmā, nā panela LED maʻalahi, a me ka ʻenehana micro-LED e mākaukau e hoʻonui i nā noi kūpono o nā pale LED. Eia kekahi, ʻo ka hoʻoikaika ʻana e hoʻomaikaʻi i ka pono o ka ikehu a hōʻemi i ka hopena o ke kaiapuni o ka hana ʻana a me ka hoʻokuʻu ʻana o LED ke alakaʻi nei i ka hoʻomohala mau o ka ʻenehana LED.
Ka hopena
I ka hopena, he huakaʻi kupaianaha ka ulu ʻana o nā pale LED, mai ko lākou hoʻomaka haʻahaʻa ʻana ma ke ʻano he kukui hōʻailona a hiki i ko lākou kūlana i kēia manawa ma ke ʻano he mana nui i ka ʻoihana hōʻike. ʻO ka holomua mau ʻana i ka ʻenehana LED ua hoʻolalelale i nā pale LED i mua o ke kamaʻilio ʻike, hāʻawi ʻia i ka ʻōlinolino like ʻole, ka mālamalama, a me ka versatility. Ke nānā nei mākou i ka wā e hiki mai ana, ua mākaukau nā pale LED e pāʻani i kahi hana koʻikoʻi i ka hana ʻana i kā mākou ʻike ʻike, ka hoʻokele ʻana i nā mea hou, a me ka hoʻololi ʻana i ke ʻano o kā mākou launa pū ʻana me nā ʻike kikohoʻe.
