Ua hoʻololi ʻo LCD i ka CRT ma ke ʻano nui, a ua hāʻule nui ke kumukūʻai, a ua lilo ia i mea kaulana loa.
E like me nā kumu backlight like ʻole, hiki ke hoʻokaʻawale ʻia ka LCD i ʻelua ʻano: CCFL a me LED.
kuhi hewa:
Manaʻo nā mea hoʻohana he hiki ke hoʻokaʻawale ʻia nā hōʻike aniani wai i nā LED a me nā LCD.I kekahi manawa, alakaʻi hewa ʻia kēia ʻike e nā hoʻolaha.
ʻO ka hōʻike LED ma ka mākeke ʻaʻole ia he hōʻike LED maoli.I ka pololei, he LED-backlit liquid crystal display.He hōʻike LCD maʻamau ka pā aniani wai.Ma ke ano, he mea hoopunipuni keia.kūlohelohe!Ua hoʻopaʻi ʻia ʻo Samsung o South Korea e ka British Advertising Association ma muli o ka uhaki ʻana i nā kānāwai hoʻolaha o ka ʻāina no ka mea ua manaʻo ʻia kāna "LEDTV" LCD TV e alakaʻi hewa i nā mea kūʻai.No nā hōʻike aniani wai, ʻo ke kī koʻikoʻi ʻo ia ka panel LCD a me ke ʻano backlight, aʻo nā panels LCD o nā hōʻike ma ka mākeke e hoʻohana maʻamau i nā panela TFT, he ʻano like.ʻO ka ʻokoʻa ma waena o nā LED a me nā LCD he ʻokoʻa ko lākou ʻano backlight: LED ʻO ka backlight a me CCFL backlight (ʻo ia hoʻi, nā kukui fluorescent) he mau diodes a me nā kukui cathode anu, kēlā me kēia.
ʻO LCD ka acronym no Liquid Crystal Display, ʻo ia hoʻi ka "hōʻike aniani wai", ʻo ia hoʻi, ka hōʻike aniani wai.Hōʻike ka LED i kahi ʻano o ka hōʻike aniani wai (LCD), ʻo ia hoʻi, kahi hōʻike aniani wai (LCD) me ka LED (light emitting diode) ma ke kumu backlight.Hiki ke ʻike ʻia aia nā LCD me nā LED.ʻO ka counterpart o LED he CCFL maoli.
Hōʻike i kahi hōʻike aniani wai (LCD) me CCFL (ke kukui cathode fluorescent) ma ke ʻano he kumu kukui hope.
ʻO ka maikaʻi o ka CCFL he hana kala maikaʻi, akā ʻoi aku ka maikaʻi o ka hoʻohana mana.
Hōʻike i kahi hōʻike aniani wai (LCD) e hoʻohana ana i nā LED (light emitting diodes) ma ke ʻano he kumu backlight, a ʻo ka mea maʻamau e pili ana i nā WLED (nā kukui keʻokeʻo keʻokeʻo).
ʻO nā pōmaikaʻi o ka LED he liʻiliʻi liʻiliʻi a me ka hoʻohana haʻahaʻa haʻahaʻa.No laila, me ka hoʻohana ʻana i ka LED ma ke ʻano he kumu backlight hiki ke hoʻokō i ka mālamalama kiʻekiʻe me ka noʻonoʻo ʻana i ka māmā a me ka lahilahi.ʻO ka hemahema nui, ʻoi aku ka maikaʻi o ka hana kala ma mua o ka CCFL, no laila ke hoʻohana mau nei ka hapa nui o nā kiʻi kiʻi ʻoihana LCD i ka CCFL kuʻuna ma ke ʻano he kumu backlight.
Kumukuai haahaa
ʻO ka mea maʻamau, ua lilo ka hōʻemi ʻana i nā kumukūʻai i kānāwai koʻikoʻi no nā ʻoihana e ola.I loko o ka mōʻaukala hoʻomohala ʻana o TFT-LCD, ʻaʻole paʻakikī ka ʻike ʻana i ka hoʻonui ʻana i ka nui o nā substrate aniani, e hōʻemi ana i ka nui o nā masks, e hoʻonui ana i ka huahana base station a me nā hua huahana, a me ke kūʻai ʻana i nā mea maka kokoke i ka hoʻomau ʻana o nā TFT- Nā mea hana LCD..
He mea koʻikoʻi ka substrate aniani no ka hana ʻana i ka TFT-LCD, a ʻo kāna kumukūʻai e pili ana ma kahi o 15% a 18% o ka huina kālā o TFT-LCD.Ua hoʻomohala ʻia mai ka laina hanauna mua (300mm × 400mm) a i ka laina ʻumi o kēia manawa (2,850mm ×3,050).mm), ua hele wale ia ma kahi manawa pōkole o iwakālua makahiki.Eia nō naʻe, ma muli o nā koi kiʻekiʻe loa no ka haku mele mele, hana a me nā kūlana kaʻina hana o nā substrates aniani TFT-LCD, ua hoʻohana lōʻihi ʻia ka honua TFT-LCD aniani substrate hana ʻenehana a me ka mākeke e Corning i United States, Asahi Glass a Uila Uila, etc. Monopolied e kekahi mau hui.Ma lalo o ka hoʻoikaika ikaika o ka hoʻomohala ʻana i ka mākeke, ua hoʻomaka pū ka ʻāina nui o koʻu ʻāina e komo pū i ka R&D a me ka hana ʻana o nā pani aniani TFT-LCD i ka makahiki 2007. I kēia manawa, he helu o nā laina hana kīʻaha TFT-LCD aniani substrate o ka lima o ka hanauna. ua kūkulu ʻia ma Kina.Hoʻolālā ʻia e hoʻolauna i ʻelua mau hana hana laina kiʻekiʻe 8.5-hanauna wai aniani aniani substrate i ka hapa ʻelua o 2011.
Hāʻawi kēia i kahi hōʻoia koʻikoʻi no ka hoʻokaʻawale ʻana i nā mea maka i luna no nā mea hana TFT-LCD ma ka ʻāina nui o koʻu ʻāina a me kahi hōʻemi nui o nā kumukūʻai hana.
ʻO ka ʻāpana nui o ka ʻenehana hana TFT ʻo ia ke kaʻina hana photolithography, ʻaʻole ia he ʻāpana koʻikoʻi o ka hoʻoholo ʻana i ka maikaʻi o ka huahana, akā he ʻāpana koʻikoʻi hoʻi e pili ana i ke kumukūʻai huahana.I ke kaʻina hana photolithography, ʻoi aku ka nui o ka nānā ʻana i ka mask.ʻO kona maikaʻi e hoʻoholo i ka maikaʻi o TFT-LCD i kahi nui, a ʻo ka hōʻemi ʻana o kona hoʻohana ʻana hiki ke hōʻemi pono i ka hoʻopukapuka ʻana i nā mea hana a hoʻopōkole i ke kaʻina hana.Me ka hoʻololi ʻana o ka hoʻolālā TFT a me ka hoʻomaikaʻi ʻana i ke kaʻina hana, ua hoʻemi ʻia ka nui o nā masks i hoʻohana ʻia i ke kaʻina hana.Hiki ke ʻike ʻia ua ulu ke kaʻina hana TFT mai ke kaʻina hana lithography 8-mask a i ʻole 7-mask lithography a hiki i ke kaʻina hana 5-mask a i ʻole 4-mask lithography i kēia manawa, e hōʻemi nui ana i ke kaʻina hana TFT-LCD a me nā kumukūʻai hana. .
4 Ua lilo ke kaʻina hana mask lithography i mea nui i ka ʻoihana.I mea e hōʻemi mau ai i nā kumukūʻai hana, ua hoʻāʻo ka poʻe e ʻimi pehea e hōʻemi hou ai i ka nui o nā masks i hoʻohana ʻia i ke kaʻina photolithography.I nā makahiki i hala iho nei, ua hana kekahi mau hui Korea i nā holomua i ka hoʻomohala ʻana i ke kaʻina hana lithography 3-mask, a ua hoʻolaha i ka hana nui.Eia naʻe, ma muli o ka ʻenehana paʻakikī o ke kaʻina hana 3-mask a me ka haʻahaʻa haʻahaʻa haʻahaʻa, aia nō ka holomua.Ma lalo o ka hoʻomohala ʻana a me ka hoʻomaikaʻi ʻana.Mai kahi hiʻohiʻona hoʻomohala lōʻihi, inā hana ka ʻenehana paʻi Inkjet (inkjet) i kahi holomua, ʻo ka hoʻokō ʻana i ka hana maskless ka pahuhopu hope loa a nā kānaka e alualu ai.
