E hiki ke hana i nā panana LCD TV e hōʻike i nā manaʻo kūikawā, i hōʻikeʻia ma Pixels . He mea nui no hoʻi e kuhikuhi i ka nui o ka nānāʻana o ka LCD TVʻaʻoleʻo ia heʻano HDTV wale nō.
Eia ka wehewehe o keʻano o ka pilina o kaʻenehana LCD a me ka hōʻike i ka hoʻoholo hoʻohui.
SDTV a me EDTV
Inā loaʻa iāʻoe kahi LCD TV i kūkuluʻia i ka makahiki 2000 a ma mua paha, hiki paha iā ia ke hoʻokūkū SDTV (Standard Definition TV) a iʻole EDTV (ʻOhana Definition Definition) aʻaʻoleʻo HDTV.
Loaʻa i ka SDTV he hoʻonā hōʻike o 740x480 (480p). ʻO ka "p" ke kūpikipiki holomua ,ʻo ia ka mea e hōʻikeʻia e nā LCD TV i nā pixels a me nā kiʻi ma kahi pakuhi.
ʻO ka EDTVs ka loaʻaʻana o kahi hoʻonākiuki pilikino maoli no 852x480. 852x480 ke helu 852 pixels ma ((hema i ka'ākau) a me 480 pika pika (i luna a lalo) ma kaʻili. ʻO nā 480 pixels hoʻi e hōʻike ana i ka helu o nā lālani a laina paha mai ka piko a hiki i lalo o ka maka. Uaʻoi aku kēia ma mua o ka ho'ākāka maʻamau, akā,ʻaʻole i kūpono i nā koi o ka hoʻonāʻana o HDTV.
Hiki ke nānā maikaʻi nā kiʻi ma kēia mau hiʻohiʻona, akā no nā DVD a me ka pōkole maʻamau maʻamau, akā,ʻaʻoleʻo HDTV. ʻO ke DVD he hōʻali Kūlana Hōʻona e kākoʻo i 480i / ka hopena (740x480 pixels).
LCD a me HDTV
I mea eʻikeʻia ai kekahi Televise (ʻo ia hoʻi, LCD TVs) e like me HDTV, pono iā ia e hōʻike i ka pale kaulike o nā laina he 20 paha (a iʻole nā pika pika). ʻO nā hoʻoholo pale hōʻikeʻike e kūpono i kēia koi (i nā pixels) 1024x768, 1280x720 , a me 1366x768.
No ka loaʻaʻana o nā pixakaʻi LCD i ka helu hope o nā pika (i kapaʻia he hōʻike hoʻonohonoho-pixel), pono e hoʻonuiʻia nā mea hōʻailona hōʻailona iʻoi aku ka hopena kiʻekiʻe no ka hoʻokomoʻana i nā helu kuhi pixel o ka hōʻike LCD maʻamau.
Eia kekahi laʻana, pono ka hōʻano hoʻokomo HDTV o 1080i a 1080p paha i ka hōʻike'ōiwi o nā 1920x1080 pixels no kahi hōʻike hoʻokahi a hoʻokahi o ka kiʻi HDTV. Eia kekahi, no ka mea, e like me ka mea i'ōlelo muaʻia, e hōʻike wikiwikiʻia ana nā kiʻi kiʻi LCD Televisions, 1080i mau hōʻano pūnaewele i hoʻolālāʻia i 1080p a i hōʻemiʻia i 768p (1366x768 pixels), 720p, 480p paha ma muli o ka hoʻohālikelike pilikino maoli o ka pāʻani LCD maʻamau .
Ma nā'ōlelo'ē aʻe,ʻaʻohe mea e like me 1080i LCD TV. Hiki i nā LCD TV ke hōʻikeʻike i nā wikiō i ka'ōnaehana hōʻiliʻili holomua, no laila inā eʻae ka LCD TV i ka hōʻailona koho 1080i, e hoʻopau a hoʻopau hou i ka hōʻailona 1080i i 720p / 768p ma nā kelepona me kahi pika'āinana 1366x768 a 1280x720 paha. hoʻolālā a 1080p paha ma nā LCD TVs me kahi kaʻina koho pixel pixels 1920x1080.
A eia kekahi, inā i loaʻa wale kāu pālakihi LCD he 8 pika pika o 852x480 aiʻole 1024x768, pono ke hōʻailonaʻia ka hōʻailona HDTV pono e hoʻokomo i ka helu 852x480 a 1024x768 pika ma ka nānāʻana o ka LCD. E hoʻonuiʻia nā hōʻailona hōʻailona HDTV e hāpai i ka māka pikahiki o ka LCD Television.
ʻO Ultra HD TV a me Beyond
Me ka holomua i ka hōʻikeʻana i keʻenehanaʻenehana,ʻoi nui ka nui o nā LCD TVs e hāʻawi ana i ka hoʻonā hōʻike hōʻike 4K (3840x2160 pixels) (i kapaʻiaʻo Ultra HD).
Eia kekahi,ʻo nā TV e hiki ke kākoʻo i 8K resolution (7680 x 4320 pixels) ʻaʻole e loaʻa i nā mea kūʻai like o ka 2017, akā, e noho ma ka mākaʻikaʻi e like me ka mea i manaʻoʻia e hiki ke hiki iā lākou, i nā mea liʻiliʻi i nā helu liʻiliʻi, ma ka 2020.
Ka Lā Lalo
I ke kūʻaiʻana i kahi LCD TV i kēia mau lā, hiki iāʻoe ke hōʻoia i ka hui nuiʻana i nā mea kūpono loa e hoʻolakoʻia he HDTV. ʻO nā TV me ka nui o nā kiʻi he 32-'inini a iʻole ka liʻiliʻi he 720p a 1080p paha nā hopena āpau, 39 mau inikena a he nui aʻoi aku paha ka nui o 1080p (HDTV) a iʻole Ultra HD (4K) hōʻikeʻike'ōiwi maoli.
Eia nō naʻe, hiki i nā hihia ma kekahi 24 mauʻonika a me ka liʻiliʻi, ma kahi e hiki ai iāʻoe ke hālāwai i ka hoʻonā hōʻike hoʻolaha 1024x768, akā, he mea nui loa kēia mau lā.
E hoʻomanaʻo wale nō aia kekahi mau LCD TV ma mua o ka hoʻohanaʻana iā SDTV a iʻole EDTVs - ināʻaʻoleʻoe e maopopo i kāuʻano, e nānā i ka lakaʻana o ka hōʻailona, e nānā i kāu kulekele hoʻohana, ke kiʻi inā he hiki ia.
