Ma ke kahua hōʻike, ke haʻi aku mākouNā hōʻike LED, ke manaʻoʻiʻo nei mākou hiki i nā mea a pau ke papa inoa i kā lākou mau pono he nui, e like me ka "nui" a me ka "mālamalama", pixel kiʻekiʻe, ʻaʻohe splicing, a me ka gamut kala ākea.A ua hoʻokūkū ikaika nā pale hōʻike LED me LCD, projection, a me nā kahua ʻē aʻe ma ke kahua hōʻike ma muli o kēia mau mea maikaʻi.ʻO nā huaʻōlelo e like me "ka pale nui" a me ka "panihi nui" piha i ka mahalo no nā pale hōʻike LED.Me ka kānalua ʻole, ʻo ka pōmaikaʻi nui loa o nā pale hōʻike LED ʻo ia ka "nui a me ka ʻole".Paʻa mau ka hoʻokūkū ma waena o nā pale hōʻike LCD a me nā pale hōʻike LED, akā me ka ulu ʻana o ka ʻenehana, ke piʻi mālie nei nā pale hōʻike LED i nā hiʻohiʻona noiʻi pitch terminal liʻiliʻi a hopu i kekahi o ka mākeke pale hōʻike LCD.Ke komo nei i ke kahua hōʻikeʻike pāʻoihana mai ka mākeke noi ʻoihana, e hoʻonui mau ana ka laulā noi o nā hōʻike LED, a hiki ke ʻōlelo ʻia kona ala hoʻomohala mai ka "nui" a "liʻiliʻi".
Ma mua o ka hoʻomohala ʻana a me ka ulu ʻana o ka ʻenehana hōʻike LED, ʻo ka ʻenehana hōʻike nui nui i ka mākeke ʻo DLP a me LCD splicing i nā pale nui.ʻO nā pale nui mua loa i haku ʻia me nā hōʻike DLP he nui me nā hili lihi iki.Me ka puka ʻana mai o nā hōʻike LCD me nā pōmaikaʻi kumukūʻai, ua hoʻonui nui ʻia ka māhele mākeke o ka LCD splicing i nā pale nui.Hōʻike nui ʻia ka ʻike ʻana o nā huahana hōʻike hōʻike LCD splicing i ʻelua mau hōʻailona ʻenehana, hoʻokahi ke kuʻi ʻana, a ʻo ka mālamalama kekahi.Ma muli o nā hiʻohiʻona hōʻike o nā hōʻike LCD, ʻaʻole hiki ke hoʻokō i kahi kiʻekiʻe o ka mālamalama, a ke kū mālie nei ke koi no nā hiʻohiʻona noi semi waho a me waho.Ke ulu wikiwiki nei ka noi no nā paneli hōʻike ʻālohilohi kiʻekiʻe mai nā mea hana mīkini holoʻokoʻa, a i kēia manawa, paʻakikī ka nui o nā kikoʻī kikoʻī e hoʻokō i ka noi mākeke.I kēia manawa, hōʻike ʻia nā pono o nā huahana pale hōʻike LED.ʻAʻole hiki i nā pale hōʻike LED ke hoʻokumu i kahi ʻōnaehana hōʻike ākea ākea me ka ʻole o nā lihi lihi, akā kūpono nō hoʻi no nā wahi ākea ākea a me ka nānā ʻana i ka lōʻihi ma muli o ke kumu hoʻokuʻu pololei a me nā hiʻohiʻona ʻano like ʻole o nā huahana pale hōʻike LED.
Ke nānā nei i hope i ka mōʻaukala hoʻomohala ʻana o nā pale nui, ua maopopo i ka wā ma mua, ʻo ka mākeke no ka splicing pale nui he haʻahaʻa loa.Ua hoʻonui a hoʻololi wale i nā hōʻike LCD papapihi kahiko a hoʻohana iā lākou i ka mākeke splicing.He nui nā drawbacks, e like me ka lawa ʻole o ka hoʻonā, paʻakikī i ka hālāwai ʻana i ka pae i koi ʻia, a i kēia wā kiʻekiʻe-definition, ʻaʻole hiki ke hoʻokō i nā pono o ka mākeke.Loaʻa i nā hōʻike LED nā mea maikaʻi loa i nā noi waho, akā i ka manawa like, ua ulu wikiwiki nā ʻenehana hōʻike e like me LCD a me ka projection.Ke haʻalele nā hōʻike LED i nā noi waho "nui", pehea ke ʻano o ka hoʻomohala ʻana i hiki iā lākou ke loaʻa i nā noi "liʻiliʻi"?
ʻO ke kaua o ka pale nui ma waena o LED a me LCD
I ke au o ka pahū ʻike, ʻoi aku ka nui o nā noi no ka splicing pale nui, a ke hoʻonui nei hoʻi kāna mau ʻoihana noi.Mai nā ʻoihana palekana lehulehu, hoʻolaha, a me nā ʻoihana kaʻa a hiki i nā hale kūʻai kūʻai, ʻoihana, a me nā ʻoihana ʻē aʻe, hiki ke ʻike ʻia ka splicing ma nā wahi āpau.Ma muli o ka mākeke nui a me ka hoʻokūkū ikaika, ʻo ka mea maʻamau ka hoʻokūkū ma waena o LED a me LCD.I nā makahiki i hala iho nei, hōʻike nā huahana LCD splicing aNā hōʻike LEDua hoʻohana nui ʻia i ka nānā wikiō, kauoha a me ka hoʻouna ʻana, e hilinaʻi ana i ka koi nui o ka mākeke ʻoihana palekana honua.Loaʻa i nā huahana hōʻike hōʻike LCD splicing hiki ke ulu.Hoʻohālikelike ʻia me LCD, ʻoi aku ka ikaika o nā hōʻike LED.Loaʻa ka pōmaikaʻi mai nā kulekele a me ka mākeke, ke neʻe mālie nei nā hōʻike LED mai nā kahua hōʻike ʻoihana e like me ka palekana, ka lawe ʻana, a me ka ikehu i nā kahua hōʻike pāʻoihana e like me nā hale kiʻiʻoniʻoni a me nā lumi kūkā.Wahi a ka ʻikepili, ʻo ka mākeke noi waho o nā pale hōʻike LED ma Kina i kēia manawa no 59%.I kēia mau lā, hoʻolaha nui ʻia ka hoʻohana ʻana o nā pale hōʻike LED, a ke piʻi nei hoʻi ko lākou alapine o ka hakakā ʻana me LCD.No laila, he aha nā mea maikaʻi o nā pale hōʻike LED i hoʻohālikelike ʻia i nā huahana hōʻike splicing LCD？
Ke pi'i nei ka "warm current".
Me ka hoʻomohala ʻana o ka liʻiliʻi liʻiliʻi, ʻaʻole pua nā pale hōʻike LED ma waho wale nō, akā noho pū kekahi i kahi mākeke ma ke kahua o nā hōʻike pāʻoihana i loko ma muli o ko lākou mau pono.Wahi a ka ʻikepili mai ka China Academy of Commerce and Industry, ke kūʻai aku nei ka loaʻa kālā o nā hōʻike LED pitch liʻiliʻi ma Kina i 16,5 biliona yuan ma 2022, a ua manaʻo ʻia e hoʻonui i 18 biliona yuan ma 2023. E like me ka ʻikepili mai Luotu Technology, ma ʻO ka hapaha mua o 2023, ʻo ka hoʻohana ʻana i nā hōʻike LED pitch liʻiliʻi i nā hiʻohiʻona o ka hālāwai kūkā ma kahi o ka hapalua, helu no 46%.Ua kiʻekiʻe ka saturation o nā noi kauoha/nānā maʻamau, a ʻo ka māhele mākeke o nā wahi moku ma lalo o 20%.ʻO kaʻoiaʻiʻo, i kēia manawa, ua loaʻa i nā LED liʻiliʻi nā hōʻike pololei i ka hana nui o P0.4 a ma luna o nā huahana, a ua ʻoi aku ma mua o nā hōʻike LCD ma nā hōʻailona pitch pitch.Ma keʻano o ka hāʻawi hoʻonā no nā hōʻike nui-nui, hiki iā lākou ke hoʻokō i nā pono o kēlā me kēia hōʻike.
Ma ke kahua o ka hōʻike pale nui, loaʻa i nā huahana spacing liʻiliʻi nā pōmaikaʻi, a ke manaʻo ʻia nei e hoʻonui ka mākeke.ʻO kapale hōʻike LED pitch liʻiliʻihoʻohana i ka ʻenehana hoʻomalu pae kiʻekiʻe pixel e hoʻokō i ka mana aupuni o ka ʻōlinolino, hoʻihoʻi kala, a me ka like ʻole o ka ʻāpana hōʻike.Ke hoʻohālikelike ʻia me nā kumu kukui kuamoʻo kahiko, loaʻa i nā kumu kukui backlight pitch liʻiliʻi ka laulā o nā hawewe emission, ʻoi aku ka wikiwiki o ka pane ʻana, a ʻoi aku ka maikaʻi o ka hoʻohālikelike ʻana i nā mea hōʻike LED kuʻuna.I ka manawa like, ʻo ka hōʻike pāʻoihana nui a me ka hoʻohana ʻana i ka home ka kuhikuhi ʻana o ke komo ʻana no kahi mamao liʻiliʻi i ka wā e hiki mai ana, a ke hoʻomākaukau nei nā mea hana nui no ka mākeke hōʻike pāʻoihana.Eia kekahi, ʻo ka hoʻomohala wikiwiki ʻana o ka mākeke moʻomeheu a me nā mākaʻikaʻi i lawe mai i nā manawa noi hou no nā hōʻike LED ma ke kahua o nā hōʻike pāʻoihana.Ke hoʻomau nei ka hoʻonui ʻana i nā hiʻohiʻona hana ma nā ʻano he nui, me nā kiʻiʻoniʻoni, hoʻolaha, haʻuki, a me nā ʻoliʻoli, e hoʻomau i ka holomua o nā hōʻike pāʻoihana.Ma nā ʻōnaehana projection, e kū mau ana ka projection kuʻuna i " bottleneck brightness " a me " bottleneck hoʻonā " ma nā pale nui.ʻO kēia mau bottlenecks ʻenehana ʻelua ka pono nui o nā LED pitch liʻiliʻi.Eia kekahi, me ka piʻi nui ʻana o ka HDR i kēia lā, ʻaʻole hiki i nā ʻōnaehana projector projection ke hoʻokō i ka hiki ke hoʻokele i ka pololei o ka pale LED e hoʻokō i ka "sub pixel by pixel" hoʻoponopono kukui.Hiki i ka pale hōʻikeʻike pitch liʻiliʻi LED ke hoʻokō i ka hōʻike 8K, ʻoi aku ka ikaika.
I ka hōʻuluʻulu ʻana, ʻo ka hoʻomohala ʻana i nā hōʻike LED he hana ia o ka nānā ʻana i nā hōʻike kūikawā a me ka ʻimi ʻana i nā hōʻike pāʻoihana.I kēia manawa, i ka hoʻomohala ʻana i nā pale hōʻike LED mai ka "nui" a i ka "liʻiliʻi" a mai ka "liʻiliʻi" a i ka "micro", he aha ka hopena i nā pale hōʻike LED inā ʻaʻole lilo hou ka "nui" i mea pono?
ʻO ka neʻe ʻana mai "B" a i "C" e koi mau ana i nā hoʻoikaika hui mai ka ʻoihana hōʻike LED
I kēia mau makahiki i hala iho nei, me ka emi ʻana o ke kumukūʻai a me ke kumu kūʻai, ua ʻoi aku ka maikaʻi o ke kumukūʻai o nā hōʻike LED pitch liʻiliʻi, a ʻoi aku ka ikaika o kā lākou hoʻololi ʻana no LCD.Ua hoʻonui mālie ʻia nā hōʻike LED mai nā kula ʻoihana i nā kiʻiʻoniʻoni a me nā kula home.I mea e hele hou aku ai, e emi mau ana ke kiko kiko o nā pale hōʻike LED, e ulu ana i ka wehewehe kiʻekiʻe a me ka wehewehe kiʻekiʻe loa, e hoʻoikaika ana e hoʻokūkū me nā ʻenehana hōʻike ʻē aʻe a komo mau i ka mākeke o nā ʻenehana hōʻike ʻē aʻe.Eia nō naʻe, i ka manawa like, ʻaʻole i hoʻoholo wale ʻia ka kūleʻa a i ʻole ka hāʻule ʻole o nā ʻenehana hōʻike e like me LED a me LCD i nā noi kūpono e ka maikaʻi o ka ʻenehana a me nā huahana.I ke kūlana o kēia manawa, hoʻomau mau ʻia nā hiʻohiʻona ʻenehana o nā pale hōʻike LED a hoʻomaikaʻi mau ʻia nā huahana.Eia nō naʻe, i ka manawa like, ua hoʻomohala wikiwiki ka ʻenehana hōʻike hōʻike LCD, e holomua nui ana i ka hōʻike kala, ke kihi ʻike, ka manawa pane, a me nā mea ʻē aʻe.Ma ke ʻano o ka hana, ua uhi ʻia kekahi o nā pono o LED.Ma kēia kaʻina hana hoʻokūkū, ʻoiai ke kumu kūʻai o nā pale hōʻike LED i hōʻike i kahi ʻano i lalo, i hoʻohālikelike ʻia me LCD a me ka projection, aia nō lākou i ke kumu kūʻai kiʻekiʻe.No nā pale hōʻike LED, aia nō kahi pale ma mua o ka neʻe ʻana mai "B" a i "C".No ka uhaki ʻana i ke kumu kūʻai, pono e hana pū ka ʻoihana hōʻike LED holoʻokoʻa e holomua.
Ma waho aʻe o ka uhaki ʻana i nā pale kumukūʻai, kekahi kumu nui nopale hōʻike LEDʻO nā huahana e neʻe mai ka B-end a i ka C-end pehea e ʻoi aku ka maikaʻi o ka hoʻokō ʻana i ka noi huahana spillover i ka pōʻaiapili o ka hoʻonui ʻana i nā mea kūʻai.Ke nānā nei i hope i ka mōʻaukala hoʻomohala o nā pā TV, mai ka ʻenehana CRT a i ka ʻenehana LCD a me OLED, a i kēia manawa i nā ʻenehana Mini LED a me Micro LED kaulana, ma ke ʻano holoʻokoʻa, ua lohi ka hana hou o ka ʻoihana TV panel, akā lawe mai kēlā me kēia ʻenehana hou i kahi. hopena hoʻopilikia.Ke hoʻohālikelike ʻia me LCD, ʻaʻole i hoʻokō ʻo Micro LED i ka hana nui ma ka pā TV ma muli o kona kumukūʻai kiʻekiʻe.I kēia manawa, pehea e hoʻomaikaʻi ai i ka hana a me ke kumukūʻai hoʻokūkū o nā pale hōʻike LED me nā hōʻailona spacing e loaʻa nei, i mea e loaʻa ai kahi mākeke nui aʻe, ua lilo ia i hana koʻikoʻi no nā ʻoihana ʻoihana.ʻO ka hoʻomaikaʻi ʻana i nā kaʻina hana nui, ka hoʻokolohua me nā hale hoʻopihapiha hou, ka hoʻohana ʻana i nā pahu mini/micro LED, a me ka hoʻonui ʻana i ka nui a me ka naʻauao hana i lilo i mau koho.He kūpono loa kēia ʻano hoʻokūkū i ka hoʻonui ʻana o ka mākeke mea kūʻai aku i ka ʻoihana, me ka ʻenehana nui a me ka nānā ʻana i ka hoʻemi ʻana i ke kumukūʻai, hiki ke hoʻoikaika i ka ulu hou ʻana o ka nui o ka mākeke hōʻike LED.
ʻAʻole ʻike ʻia nā loli o ka wā e hiki mai ana, akā i kēia au o nā huahana hōʻike like ʻole a me ka hoʻokūkū ʻana no ka ʻike mea kūʻai aku, pono e ʻimi hou ʻia ka ʻoihana hōʻike LED holoʻokoʻa: he aha nā hiʻohiʻona ʻē aʻe e hōʻike i nā huahana e hiki ke wehe maikaʻi i ka mākeke home. loaʻa?Pehea mākou e hoʻokokoke ai i ka mākeke mea kūʻai?No nā mea hana pale hōʻike LED, ma waho aʻe o ka hopu ʻana i kā lākou mau pono ʻenehana, pono paha lākou e noʻonoʻo e hoʻonui a hoʻonui i nā kahua he nui.
