ʻO nā hōʻike aniani wai (LCD) he ʻāpana koʻikoʻi o nā TV hou, nā kelepona a me nā papa. Hoʻokaʻawale ʻia ka ʻāpana aniani i nā ʻāpana he nui (pixels), a hiki ke hoʻoponopono ʻia kā lākou transmittance kukui ma o ka hoʻohana ʻana i kahi kahua uila.
I loko o nā kīwī pālahalaha i hoʻolako ʻia me nā LED kuʻuna, hana ʻia ka backlight e pono ai e nā haneli o nā LED; no ka mea e pono ana ka LED hoʻokahi i kahi ākea nui, ʻaʻole hiki ke loaʻa i kahi ākea hou aʻe. Ua ʻike ʻia ka hemahema: ʻaʻole hiki ke hoʻokō i nā kukui ʻoniʻoni LCD maoli me kahi matrix LED koʻikoʻi. Ua puka mai ka ʻenehana mini-LED hou i ka makahiki 2020, ua hoʻāla ka ʻoihana i ka hoihoi nui. No ka mea he liʻiliʻi loa nā mini-LED (0.05 a 0.2 mm) i hoʻohālikelike ʻia me nā LED kuʻuna, hiki i kēia manawa ke hana i nā kukui hope mai nā ʻumi tausani o nā kukui mini-LED. Sources.Mini LEDs ua pūʻolo i loko o ka mea i kapa 'ia wahi kukui, kahi o kela a me keia wahi i nui loa ka liʻiliʻi ma mua o kuʻuna LED. Manaʻo i ka hoʻomaikaʻi maikaʻi ʻana i ka ʻokoʻa a me nā ʻeleʻele hohonu.
ʻOi aku ka paʻakikī o ka hana ʻana i nā LED a i ʻole nā mini-LED ma mua o ka maʻalahi o ka ʻili i hōʻike ʻia e nā ʻāpana-ʻoi loa no ka mea pono e hana ʻia kekahi o nā hana hana pono ma lalo o nā kūlana vacuum. Hoʻohana ʻia ke kaʻina hana no ka hoʻokomo ʻana i kahi papa ʻano metala ma luna o ka wafer. Ma kēia kaʻina hana, ua hoʻopili ʻia ka mea i hoʻopaʻa ʻia i ka lattice kristal e noho nei ma ke ʻano i kauoha ʻia: he liʻiliʻi wale nō nā ʻāpana atomic mānoanoa, e hoʻokō ʻia i ke ʻano aniani o ka wafer. .No ka hōʻoiaʻanaʻaʻole i loko o ka uhiʻana i nā mea haumia, pono e hanaʻia kēia kaʻina hana ma lalo o ka paleʻana i ka'ōpala.ʻO kēia kahi e hoʻokomoʻia ai ka valve auhau waiwai. ʻO Kina, a me ʻAmelika Hui Pū ʻIa—ke hilinaʻi nei i nā kīwaha VAT.
I mea e hana ai i ka hoʻololi maikaʻi ʻole i ka LED, pono e waiho ʻia kahi ʻāpana ultra-thin hou a laila etched i kahi kūpono. hoʻonui ʻia ka hoʻoheheʻe ʻana i ka mahu (PECVD) no ka waiho ʻana i nā papa, a me ka etching maloʻo kemika plasma no ka wehe ʻana iā lākou. No ka mea pono e hoʻokō ʻia kēia mau kaʻina hana ma lalo o nā kūlana ʻawaʻawa, he kuleana nui ka VAT vacuum valve ma aneʻi.
I ka wā e hiki mai ai kahi holomua maoli i ka wā e hiki mai ana, e lilo maoli nā kīwaha VAT i hoʻokahi o lākou. Ma hope o nā mea a pau, e like me ka poʻe akamai, ʻo nā mini-LED he wahi hoʻomaha wale ia i kahi kumu kukui liʻiliʻi: micro-LEDs. Hoʻohālikelike ʻia me nā mini-LED, kēia ʻO nā mea liʻiliʻi maoli he 50 a 100 mau manawa liʻiliʻi. Kahaha: ʻO ka micro-LED liʻiliʻi loa i kēia manawa he ʻaoʻao ka lōʻihi o 3 microns, ʻo ia hoʻi ʻekolu tausani o ka millimeter! ʻO ka mea ʻē aʻe, ʻo ka ʻenehana micro-LED e hōʻike ana i kahi hoʻololi paradigm maoli. Hoʻohālikelike ʻia me nā pale LCD, (mini) pāʻani nā LED i kahi kūlana lua inconspicuous ma ke ʻano he kumu kukui hope. Ma nā pale uila uila, hoʻomālamalama pono kēlā me kēia pika, hiki ke hoʻopau ʻia a hiki ke hoʻopau ʻia.
ʻOiai he liʻiliʻi ka Micro-LED, nui ka hopena. ʻO ka hoʻololi ʻana mai ka micro a micro LED ʻenehana ua lawe mai i nā pōmaikaʻi nui. ʻO kekahi o lākou e ʻike ʻia, e like me ka spectrum kala nui, ʻoi aku ka ʻōlinolino, ʻoi aku ka ʻokoʻa, a me ka wikiwiki o ka refresh rate. e like me ka haʻahaʻa mana hoʻohana a me ka lōʻihi o ke ola, he intangible, akā, like important.I loko o keia pōʻaiapili, he hou hanauna o LED mea loa paha e lilo i veritable holoholona hihiu.
Hoʻopuka ʻo VAT Group AG i kēia ʻike ma Dekemaba 14, 2021, a nona wale ke kuleana no ka ʻike i loko.
