Ua ʻike mākou no ka manawa lōʻihi he ʻekolu ʻano mea: paʻa, wai a me ke kinoea. Hoʻonohonoho ʻia ke kikowaena o ka nui o nā molekole wai me ka ʻole o ka maʻamau, akā inā lōʻihi kēia mau molekala (a i ʻole palahalaha), hiki ke maʻamau ko lākou ʻano. Hiki iā mākou ke hoʻokaʻawale i ke kūlana wai i nā ʻano he nui. ʻO ka wai me ka ʻole kuhikuhi maʻamau i kapa ʻia ʻo ka wai pololei, ʻoiai ʻo ka wai me ke kuhikuhi kuhikuhi i kapa ʻia ʻo ka wai aniani, a i ʻole ke aniani wai no ka pōkole. kelepona, calculators he wai aniani huahana.Liquid kristal, i loaʻa i loko o 1888 e ka Austrian botanist Reinitzer, he organic pūhui i mau molecular hoʻonohonoho ma waena o solids a me ka wai. no ka pā lōʻihi, ka laulā o kahi 1 nm a 10 nm, ma lalo o nā māla uila o kēia manawa, e hoʻonohonoho nā molekala aniani wai i nā lula i hoʻololi ʻia 90 degere, hana.i ka ʻokoʻa o ka transmittance māmā, no laila ka mana ON / OFF ma lalo o ka ʻokoʻa ma waena o ka mālamalama a me ka malu, kēlā me kēia pika e like me ke kumu o ka mana, hiki ke hana i ke kiʻi.
ʻO ke kumu o ka hōʻike aniani wai he aniani wai ma lalo o ka hana o nā ʻano uila like ʻole e lilo i kukui o nā ʻano like ʻole.Ua māhele ʻia ʻo LCD ma ka physics i ʻelua mau ʻāpana, ʻo kekahi ʻo Passive Passive (ʻike ʻia ʻo Passive), a ʻo kēia ʻano LCD ponoʻī ʻaʻole ia e ʻā, pono ke kumu kukui waho, e like me ke kūlana o ke kumu kukui, a hiki ke māhele ʻia i ka noʻonoʻo a me ʻano hoʻoili ʻelua ʻano.LCD Passive me ka haʻahaʻa kumu kūʻai, akā, ʻaʻole nui ka ʻōlinolino a me ka ʻokoʻa, akā liʻiliʻi ka Angle kūpono, liʻiliʻi ka saturation kala LCD Passive o ke kala, no laila ʻaʻole lawa ke kala.ʻO kekahi ʻano he kumu mana, ʻo TFT (Thin FilmTransitor).ʻO kēlā me kēia LCD he transistor hiki ke ʻālohilohi, no laila ʻaʻole ʻo LCD.Hoʻokumu ʻia ka pale LCD me nā laina laina LCD he nui, ma ka hōʻike LCD monochrome, ʻo kahi aniani wai he pixel, akā i ke kala wai aniani hōʻike kēlā me kēia pika he ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli ʻekolu LCD pū.I ka manawa like hiki ke noʻonoʻo ʻia ma hope o kēlā me kēia LCD he 8-bit papa inoa, hoʻopaʻa inoa nā waiwai e hoʻoholo i ka mālamalama o nā ʻāpana LCD ʻekolu i kēlā me kēia, akā ʻo ka waiwai o ka papa inoa ʻaʻole e hoʻokele pololei i ka ʻōlinolino o ka ʻeleu aniani wai ʻekolu, akā. e kahi "palette" e kipa aku ai. ʻAʻole maoli ka loaʻa ʻana o kahi papa inoa kino no kēlā me kēia pika.ʻO ka ʻoiaʻiʻo, hoʻokahi lālani o nā papa inoa i hoʻolako ʻia, i hoʻopili ʻia i kēlā me kēia lālani o nā pika a hoʻouka i nā mea o kēlā lālani.
Ke nānā aku nei nā kristal wai e like me ka wai, akā ʻo kā lākou crystalline molecular structure e like me kahi paʻa. , e hiki i na molekele aniani wai ke hele i ka malamalama; Hiki ke ho'oholo 'ia ke ala o ka malamalama ma o ka wai aniani wai e ka ho'onohonoho 'ana o nā molekala i ho'okumu 'ia, kekahi 'ano o nā mea pa'a. e like me na mole. Ma ke ano, ua like loa na ko'i loloa o keia mau molekele e like me ka laau. kū pololei kekahi i kekahi (90 degere), ʻo ia hoʻi, inā pili nā molekole ma ka papa hoʻokahi i ka ʻākau-hema, ua hoʻolikelike ʻia nā molekole ma ka papa ʻē aʻe ma ka hikina-komohana, a ʻo nā molekole ma waena o kaʻelua mau mokulele i koi ʻia i loko o kahi wili 90. No ka hele ʻana o ka mālamalama i ke ala o nā molekala, ua wili pū ʻia e nā degere 90 i kona hele ʻana i loko o ke aniani wai. me ke kū pololei, e ʻae ana i ka māmā e kahe pololei me ka ʻole o ka wili.Hoʻokaʻawale ʻole ke kukui kūlohelohe ma nā ʻaoʻao āpau. Hoʻokumu kēia mau laina i ka ʻupena e ālai i nā kukui a pau ʻaʻole like me kēia mau laina.ʻO ka laina kānana polarized e pili pono ana i ka mea mua, no laila e hoʻopaʻa loa ia i ke kukui polarized. Inā wale nō nā laina o nā kānana ʻelua i kūlike loa, a inā ua wili ʻia ke kukui ponoʻī e kūlike i ka kānana polarized lua, hiki i ke kukui ke komo i loko. .LCDS i loko o 'elua mau vertically polarized kānana, no laila, maʻamau lākou e ālai i kekahi kukui e ho'āʻo ana e komo. Akā naʻe, no ka mea, ua piha nā kānana ʻelua me nā kristal wai wili, ma hope o ka hele ʻana o ke kukui i ka kānana mua, ua wili ʻia 90 degere. e nā molekele aniani wai, a ma hope loa e hele i ka kānana ʻelua. Inā, ma kekahi ʻaoʻao, ua hoʻopili ʻia kahi volta i ka aniani wai, e hoʻonohonoho hou nā molekala iā lākou iho i ʻole e wili hou ʻia ke kukui, no laila. e ālai ʻia e ka kānana ʻelua. ʻO Synaptics TDDI, no ka laʻana, hoʻohui i nā mea hoʻopili paʻi a hōʻike i nā drive i loko o kahi pahu hoʻokahi, e hōʻemi ana i ka helu o nā ʻāpana a me ka maʻalahi o ka hoʻolālā. ʻO ClearPad 4291Kākoʻo i kahi hoʻolālā inline hybrid multipoint e hoʻohana pono ana i kahi papa i loaʻa i loko o kahi hōʻike aniani wai (LCD), e hoʻopau ana i ka pono no nā mea ʻike paʻi ʻokoʻa. ʻO nā hāʻinaʻelua e hoʻomāmā i nā pale paʻi a me nā hōʻike'ālohilohi, e kōkua ana i ka hoʻomaikaʻiʻana i ka nani o ka smartphone a me ka papa papa. nā pūʻulu o nā electrodes i hoʻopaʻa ʻia a i ʻike ʻia, kino aniani wai, electrode, aniani, kānana polarized a me ka noʻonoʻo.
