ʻO ke kumukānāwai kristal wai STN
Ua ʻike ʻia ka mea nānā LCD mua loa o ka honua i nā makahiki 1970 a ua kapa ʻia ʻo ia he TN-type LCD monitor (Twisted
Nematic, twisted nematic).1980s, STN LCD (Super Twisted Nematic)
ʻIke ʻia i ka manawa like, ua noi ʻia ka ʻenehana TFT wai aniani (ThinFilmTransistor thin film transistor).
E kamaʻilio mua kākou e pili ana i ke kumu o TN LCD.ʻO ka loina hōʻike o STN LCD a me TN LCD like.
Ua wili ʻia nā molekala ma nā kihi ʻokoʻa.
Hoʻopili ʻia kahi aniani wai nematic ma waena o ʻelua ʻāpana aniani.Hoʻopili mua ʻia ka ʻili o kēia aniani me kahi kiʻi ʻoniʻoni a me ka conductive no ka uila.
Polarizers, a laila e hoʻopaʻa i kahi mea hoʻoponopono ʻili ma ke aniani me ka electrode kiʻiʻoniʻoni lahilahi e hoʻohaʻahaʻa i nā kristal wai-he kikoʻī a kūlike me ka ʻili aniani.
Kūlike ʻia nā helehelena.ʻO ke kūlana kūlohelohe o ke aniani wai he wili o 90 degere.Hiki ke hoʻohana ʻia ke kahua uila e hoʻololi i ke aniani wai, a me ka ʻōnaehana refraction o ke aniani wai
Hoʻololi ka helu me ke kuhikuhi o ke aniani wai, a ʻo ka hopena ʻo ka hoʻololi ʻana o ka polarization o ke kukui ma hope o ka hele ʻana i ka aniani wai TN.E koho wale i ka pono
Hoʻololi ka mānoanoa o ke kukui i ka polarization o ke kukui ma ka pololei 90 °, a hiki ke hoʻohana ʻia ʻelua polarizers e hana i ka mālamalama hiki ʻole ke hele.A me ka wāwae
Hiki i ka voltage lawa ke hoʻohālikelike i ke kuhikuhi o ke aniani wai me ke kuhikuhi o ke kahua uila, i ʻole e loli ka polarization o ke kukui a hiki i ke kukui ke hele.
ʻO ka lua polarizer.No laila, hiki ke hoʻomaluʻia ka'ōlinolino o ke kukui.E like me ka mea i ʻōlelo ʻia ma mua, ʻo nā mea hōʻike o ke aniani wai wai ʻano STN a me ke aniani wai ʻano TN
Ua like ka loina, koe wale no ka hoohuli ana i ka malamalama hanana ma 180 ~ 270 degere ma kahi o 90 degere.Eia kekahi, kahi hōʻike aniani wai maʻalahi TN-type.
ʻElua wale nō hoʻololi o ka mālamalama a me ka malu.ʻO ka STN LCD he ʻōmaʻomaʻo māmā a ʻalani.Akā inā ma ka LCD STN monochrome kahiko
E hoʻohui i kahi kānana kala i ka hōʻike, a e puʻunaue i kēlā me kēia pika i ka matrix hōʻike monochrome i ʻekolu sub-pixels.
Hōʻike ka kānana i nā kala kumu ʻekolu o ka ʻulaʻula, ka ʻōmaʻomaʻo, a me ka uliuli, a hiki ke hōʻike ʻia nā kala.
