ʻO nā pale TFT LCD kekahi o nā ʻenehana hōʻike i hoʻohana nui ʻia i nā mea uila i kēia manawa.Loaʻa iā ia ka hōʻike kiʻi kiʻekiʻe ma o ka hoʻohui ʻana i kahi transistor kiʻiʻoniʻoni lahilahi (TFT) i kēlā me kēia pika.Ma ka mākeke, nui nā ʻano o nā pale TFT LCD, kēlā me kēia me kona mau hiʻohiʻona a me nā pono ponoʻī.E hōʻike ana kēia ʻatikala i ke ʻano VA, ʻano MVA, ʻano PVA, ʻano IPS a me ka pale LCD ʻano TN, a wehewehe i ko lākou mau palena.
ʻO ke ʻano VA (Vertical Alignment) kahi ʻenehana pale TFT LCD maʻamau.Hoʻohana ʻia kēia ʻano o ka pale i kahi ʻano molekula kristal wai i hoʻonohonoho pono ʻia, a mālama ʻia ke degere o ka hoʻouna ʻana i ka māmā ma o ka hoʻoponopono ʻana i ka orientation o nā molekala kristal wai.Loaʻa i nā pale VA ka ʻokoʻa kiʻekiʻe a me ka saturation kala, hiki i nā ʻeleʻele hohonu a me nā kala maoli.Eia kekahi, ʻo ka pale VA ka nui o ka nānā ʻana i nā kihi ākea, hiki ke mālama i ke kūlike o ka maikaʻi o ke kiʻi ke nānā ʻia mai nā kihi like ʻole.ʻO 16.7M kala (8bit panel) a me ka nui o ka nānā ʻana i nā kihi ʻoi loa kona mau hiʻohiʻona ʻenehana.I kēia manawa ua māhele ʻia nā panela VA-type i ʻelua ʻano: MVA a me PVA.
ʻO ke ʻano MVA (Multi-domain Vertical Alignment) kahi mana i hoʻomaikaʻi ʻia o ke ʻano VA.Loaʻa kēia ʻano pale i ka maikaʻi o ke kiʻi a me ka manawa pane wikiwiki ma ka hoʻohui ʻana i nā electrodes hou i nā pika.Hoʻohana ʻo ia i nā protrusions e hana i ke aniani wai ʻaʻole i ʻoi aku ka kuʻuna kuʻuna i ka wā e noho mālie ai, akā paʻa ia ma kekahi kihi;ke hoʻohana ʻia ka volta, hiki ke hoʻololi koke ʻia nā molekole aniani wai i kahi kūlana ākea e hiki ai i ke kukui hope ke hele maʻalahi.Hiki i ka wikiwiki wikiwiki ke hoʻopōkole i ka manawa hōʻike, a no ka hoʻololi ʻana o kēia protrusion i ka alignment o nā molekala kristal wai, i ʻoi aku ka laulā o ka ʻike maka.Hiki ke piʻi ka piʻi ʻana o ke kihi ʻike ma mua o 160 °, a hiki ke hoʻopōkole ʻia ka manawa pane i lalo o 20ms.ʻOi aku ka ʻokoʻa o ka pale MVA, ʻoi aku ka nui o ka ʻike maka a me ka wikiwiki hoʻololi pixel.Eia hou, hiki i ka pale MVA ke hoʻemi i ka hoʻololi kala a me ka motion blur, e hāʻawi ana i kahi hopena kiʻi ʻoi aku ka maopopo.
ʻO ke ʻano PVA (Patterned Vertical Alignment) kekahi ʻano hoʻomaikaʻi hou o ka ʻano VA.He ʻano panel kēia i hoʻokumu ʻia e Samsung, ʻo ia ka ʻenehana hoʻoponopono kiʻi kū i luna.Hiki i kēia ʻenehana ke hoʻololi pololei i ke ʻano o kāna ʻāpana aniani wai, i hiki ke hoʻomaikaʻi maikaʻi ʻia ka hopena hōʻike, a ʻoi aku ka maikaʻi o ka puka aniani a me ka ratio like ʻole ma mua o MVA..Eia kekahi, ma ke kumu o kēia mau ʻano ʻelua, ua hoʻonui ʻia nā ʻano i hoʻomaikaʻi ʻia: S-PVA a me P-MVA ʻelua mau ʻano paneli, ʻoi aku ka maʻamau i ka hoʻomohala ʻana i ka ʻenehana.Hiki i ka huina nānā ke hiki i 170 degere, a me ka manawa pane Ua hoʻomalu ʻia i loko o 20 milliseconds (hiki i ka overdrive acceleration ke hiki i 8ms GTG), a hiki ke maʻalahi ka ʻokoʻa ma mua o 700:1.He ʻenehana kūlana kiʻekiʻe ia e hōʻemi ana i ka leakage māmā a me ka hoʻopuehu ʻana ma o ka hoʻohui ʻana i nā ʻano hoʻohālike maikaʻi i ka papa aniani wai.Hiki i kēia ʻenehana pale ke hāʻawi i ka ratio ʻokoʻa kiʻekiʻe, ʻoi aku ka nui o ka ʻike maka a me ka hana kala ʻoi aku ka maikaʻi.He kūpono nā pale PVA no nā hiʻohiʻona e koi ana i ka ʻokoʻa kiʻekiʻe a me nā kala ʻulaʻula, e like me ka hana kiʻi a me nā hale kiʻiʻoniʻoni.
ʻO ke ʻano IPS (In-Plane Switching) kekahi ʻenehana pale TFT LCD maʻamau.ʻAʻole like me ke ʻano VA, ua hoʻohālikelike ʻia nā molekala aniani wai i ka pale IPS ma ka ʻaoʻao ākea, e maʻalahi ai ka hele ʻana o ka mālamalama i ka papa aniani wai.Hiki i kēia ʻenehana pale ke hāʻawi i kahi ākea o ka nānā ʻana i nā kihi, ʻoi aku ka pololei o ka hana kala a me ka ʻōlinolino kiʻekiʻe.Ua kūpono nā pale IPS no nā noi e koi ana i nā kihi ākea ākea a me ka hoʻolilo kala maoli, e like me nā mea hana e like me nā papa a me nā kelepona paʻalima.
ʻO ke ʻano TN (Twisted Nematic) ka ʻenehana pale TFT LCD maʻamau.He ʻano maʻalahi kēia ʻano pale a me ke kumu kūʻai haʻahaʻa, no laila ua hoʻohana nui ʻia i ka nui o nā noi.Eia naʻe, loaʻa i nā pale TN kahi ākea o ka nānā ʻana a me ka maikaʻi ʻole o ka hana kala.He kūpono ia no kekahi mau noi ʻaʻole koi i ke kiʻi kiʻekiʻe, e like me nā nānā kamepiula a me nā pāʻani wikiō.
Ma waho aʻe o ka hoʻolauna ʻana o nā ʻano pale TFT LCD ma luna, e wehewehe ʻia ko lākou mau palena.
ʻO ka mua ka hoʻohālikelike (Contrast Ratio).ʻO ka ratio like ʻole he ana o ka hiki o kahi mea hōʻike ke hoʻokaʻawale i waena o ka ʻeleʻele a me ke keʻokeʻo.ʻO ka ʻokoʻa kiʻekiʻe, hiki i ka pale ke hōʻike maopopo i ka ʻokoʻa ma waena o ka ʻeleʻele a me ke keʻokeʻo.ʻO nā ʻano VA, MVA, a me nā ʻano PVA o nā pale LCD i ʻoi aku ka nui o nā ratio like ʻole, e hāʻawi ana i nā kikoʻī kiʻi nui aʻe a me nā kala like ʻole.
Hahai ʻia e ke kihi nānā (Viewing Angle).ʻO ke kihi nānā ʻana e pili ana i ka laulā o nā kihi i hiki ke mālama ʻia ka maikaʻi o ke kiʻi i ka wā e nānā ana i kahi pale.ʻO nā ʻano IPS, VA, MVA, a me PVA o nā pale LCD maʻamau ka nui o nā kihi nānā, e ʻae i nā mea hoʻohana e hauʻoli i nā kiʻi kiʻekiʻe ke nānā ʻia mai nā kihi like ʻole.
ʻO kekahi mea ʻē aʻe ka manawa pane (Manawa pane).ʻO ka manawa pane e pili ana i ka manawa e pono ai no ka hoʻololi ʻana o nā molekala kristal wai mai kekahi mokuʻāina a i kekahi.ʻO ka manawa pane ʻoi aku ka wikiwiki, hiki i ka pale ke hōʻike pololei i nā kiʻi e holo wikiwiki ana, e hōʻemi ana i ka motion blur.ʻO nā pale LCD ʻano MVA a me PVA ʻoi aku ka wikiwiki o ka pane ʻana a kūpono i nā hiʻohiʻona e koi ana i ka hana kiʻi kiʻekiʻe.
ʻO ka hope loa ka hana kala (Color Gamut).ʻO ka hana kala e pili ana i ka laulā o nā waihoʻoluʻu e hiki ai i kahi mea hōʻike ke hana.ʻO nā ʻano IPS a me PVA o nā pale LCD he ʻoi aku ka laulā o ka hana kala a hiki ke hōʻike i nā kala ʻoi aku ka ʻoiaʻiʻo a me ka ʻike.
I ka hōʻuluʻuluʻana, nui nāʻano o nā pale TFT LCD ma ka mākeke, aʻo kēlā me kēiaʻano he mau hiʻohiʻona a me kona pono pono'ī.ʻOkoʻa ka ʻano VA, ʻano MVA, ʻano PVA, ʻano IPS, a me nā pale LCD ʻano ʻano TN i ka ʻokoʻa, ke kihi nānā, ka manawa pane, a me ka hana kala.Ke koho ʻana i kahi pale LCD, pono nā mea hoʻohana e koho i ke ʻano kūpono loa e like me kā lākou makemake a me kā lākou kālā.Inā no nā noi ʻoihana a i ʻole ka hoʻohana ʻana i kēlā me kēia lā, hiki i ka ʻenehana pale TFT LCD ke hāʻawi i ka maikaʻi o ke kiʻi a me ka ʻike ʻike.
