ʻO keʻano o kāu kiʻi TV
Ke nohoʻoe e nānā i kāu polokalamu punahele a iʻole kiʻiʻoniʻoni ma kāu kiʻi wikiō a wikiō paha,ʻikeʻoe i ka mea iʻikeʻia he kiʻi o nā kiʻi piha, e like me ke kiʻi paʻi kiʻi. Eia naʻe, hoʻopunipuni nā kiʻi. Ināʻike ponoʻoe i kou mau maka i kahi o ka TV a iʻole ka nānāʻana, eʻikeʻoe ua hana ia i nā liʻiliʻi liʻiliʻi i hoʻopaʻaʻia i ka paepae ākea a me ka laina kaulike ma'ō a ma luna a ma lalo o kaʻili.
ʻO keʻano kūpono maikaʻi ka nūpepa maʻamau. Ke heluhelu mākou, ua like mākou eʻike nei i nā kiʻi a me nā leka hoʻokahi, akā ināʻoe e nānā pono, a iʻoleʻoe eʻike i ke aniani hōʻailona, eʻikeʻoe i kēia mau leka a me nā kiʻi i hanaʻia i nā kikoʻu liʻiliʻi.
Hoʻokumuʻia ka Pixel
ʻO nā kikowaena ma kahi pāʻani TV, ke nānā wikiō, ka leka PC, ka pona, a me nā papa papa a me nā'ōkuhi'ōlaiu paha, i kapaʻiaʻo Pixels .
Ho'ākākaʻia kahi pixel e like me kahi kiʻi kiʻi. ʻO kēlā me kēia pixel heʻulaʻula,'ōmaʻomaʻo, a me kaʻulaʻula (i kapaʻiaʻo subpixels). ʻO ka helu o nā pixels e hiki ke hōʻikeʻia ma ka pakuhi e hoʻoholo i ka hoʻoholo o nā kiʻi i hōʻikeʻia.
No ka hōʻikeʻana i kahi hoʻonāʻikepili kūikawā, pono e holo ka pihi mua o nā pika ma'ō a'ō o ka pākuʻi a ma luna a lalo i ka maka i ka'ōmaʻomaʻo, hoʻonohonohoʻia i nā lālani a me nā koluma.
No ka hoʻoholoʻana i ka helu helu o nā pixel e uhi ana i ka ili honua a pau, hoʻonuiʻoe i ka helu o nā pika paepae i ka lālani hoʻokahi me ka helu o nā pixels vertical ma kekahi papa. ʻO kēia paukū i kapaʻiaʻo Pixel Density .
Nā hiʻohiʻona o ka pilina Hua'ōlelo / Pixel Density Relationship
Eia kekahi mau hiʻohiʻona o Pixel Density no ka hōʻikeʻokoʻaʻana i nā manaʻo ma nā TV o kēia lā (LCD, Plasma,'OLED), a me nā mea wikiō (LCD, DLP):
- 480i / p he 740 'ākea x 480 vertical pixels = 345,600 hapa pixels.
- 720p e pili ana i 1,280 i kaulike x 720 vertical pixels = 921,600 total pixels.
- 768p he 1,366 ākea a 768 vertical pixels = 1,049,088 nā pixels.
- 1080i / 1080p he 1,920 horizon x x 1080 vertical pixels = 2,073,600 hapa pixels.
- 4K (Kelehua Kūʻai) kahi 3,840 kūmole x 2,160 vertical pixels = 8,294,400 nā pixels.
- 4K (Cinema Standard) he 4,096 paepae x 2,160 vertical pixels = 8,847,360 nui pixels.
- 8K ia 7,680 horizontal x 4,320 vertical pixels = 33,177,600 nā pixels
ʻO ka pihi pixel a me ka lahilahi o ka maka
Ma waho aʻe o ka pixel pika (hoʻololi), aia kekahi kumu e noʻonoʻo ai: ka nui o ka pakuhi e hōʻike ana i nā pika.
ʻO ka mea nui e kuhikuhi i kēia ma muli o ka nui o ka'ōkuhi maoli,ʻaʻole e loli ka helu kaulike / vertical pika a me ka pixel pika no kahi hoʻonāʻana. I kekahi'ōlelo'ē aʻe, ināʻoe he 1080p TV, aia 1,920 pika e holo holoʻokoʻa ana ma kaʻaoʻao ākea, i kēlā me kēia lā, a 1,080 pika e holo pololei ana ma lalo o ka pākū, ma kēlā me kēia kolamu. Loaʻa ka hopena pixel o kahi 2.1 miliona.
I kekahi'ōlelo'ē aʻe, ua loaʻa ka helu helu 32-inch e hōʻike ana i 1080p o ka hoʻonākiho i ka helu like o nā pika e like me 55-inch 1080p TV. Hoʻohana like ia me nā mea wikiō wikiō. Hiki i ka 1080p wikiō wikiō ke hōʻike i ka helu like o nā pika ma kahi nānā he 80 a 200 paha.
Pixels Per Inch
Eia nō naʻe, inā e mau ana ka helu o nā pixel no kahi kaulike pixel maʻamau ma o nā nui o nā kiʻi, he aha ka loli i ka helu o pixels-per-inch . Ma nā'ōlelo'ē aʻe, i ka nui o ka nui o ka hulu, e nui ka pixels iʻikeʻia e hoʻopihapiha i ka'ōkuhi me ka helu pololei o nā pixel no kahi hoʻoholo. Hiki iāʻoe ke helu i ka helu o nā pika ma ka'īnika no nā pilina hoʻohālikelike kiko'ī a me nā hiʻohiʻona.
Pixels Per Inch - TV a me Video Projectors
He mea nui hoʻi e hoʻomaopopo i kēia me nā mea wikiō wikiō, e hiki ke hoʻololiʻia nā pixels i kēlā me kēia'īnika no kekahi'ōmike kūikawā ma muli o kaʻike nui i hoʻohanaʻia. Ma nā'ōlelo'ē aʻe,ʻaʻole e like me nā TV i loaʻa ka nui o nā hiʻohiʻona (ma ka'ōlelo'ē aʻe, he 50 mau'inima ka TV ma 50 mau'eneni ka TV), hiki i nā mea hana kiʻiʻoniʻoni ke hōʻike i nā kiʻi i loko o ka nui o nā kiʻi nui, e pili ana i ka hoʻolālā leka a ka mea ka mamao o ka pakuhi mai kahi pale aiʻole ka paia.
Eia kekahi, me nā papahana 4K, aia nāʻano likeʻole i kaʻikeʻiaʻana o nā kiʻi ma kahi pakuhi e pili ana i ka nui o ka nui, ka pixel pika, a me nā pika pika ma waena o ke aniani.
Ka Lā Lalo
ʻOiaiʻo Pixels ke kumu o ka hoʻokomoʻiaʻana o kahi kiʻi TV, aia kekahi mau mea e pono eʻike i nā kiʻi kiʻi maikaʻi maikaʻi o TV a me nā kiʻi wikiō, e like me ke kala, keʻano likeʻole, a me ka'ōlohi. Ma muli o kou nui o nā pixels,ʻaʻoleʻo ia e hoʻohālikelike ana eʻikeʻoe i ke kiʻi kūpono ma kāu pāʻani TV a iʻole ke kiʻi wikiō.
