Pehea e hana ai nā LCD

I kēia manawa, hoʻokumu ʻia ka hapa nui o nā ʻenehana hōʻike aniani wai i nā ʻenehana ʻekolu o TN, STN, a me TFT.No laila, e kūkākūkā mākou i kā lākou mau loina hana mai kēia mau ʻenehana ʻekolu.Hiki ke ʻōlelo ʻia ʻo ka ʻenehana hōʻike aniani wai ʻano TN ʻo ia ka mea maʻamau o nā hōʻike aniani wai, a hiki ke ʻōlelo ʻia e hoʻomaikaʻi ʻia me ke ʻano TN ke kumu.Pēlā nō, ʻoi aku ka maʻalahi o kāna kumu hana ma mua o nā ʻenehana ʻē aʻe.E ʻoluʻolu e nānā i nā kiʻi ma lalo nei.Hōʻike ʻia ma ke kiʻi he kiʻi hoʻolālā maʻalahi o kahi hōʻike aniani wai TN, me nā polarizers ma nā ʻaoʻao kū pololei a me ke alo, kahi kiʻi ʻoniʻoni me nā awāwa maikaʻi, kahi mea aniani wai, a me kahi substrate aniani conductive.ʻO ke kumu hoʻomohala ʻo ia ka waiho ʻana o ka mea aniani wai ma waena o ʻelua mau aniani conductive māmā me kahi polarizer kūpaʻa i hoʻopili ʻia i ka axis optical, a ua hoʻololi ʻia nā molekala aniani wai e like me ke kuhikuhi ʻana o nā grooves maikaʻi o ke kiʻi alignment.Inā ʻaʻole i hoʻokumu ʻia ke kahua uila, e maʻalahi ke kukui.Komo ia mai loko mai o ka pā polarizing, hoʻololi i kona ala hele e like me nā molekala aniani wai, a laila puka i waho mai kēlā ʻaoʻao.Inā hoʻoikaika ʻia nā ʻāpana ʻelua o ke aniani conductive, e hana ʻia kahi māla uila ma waena o nā ʻāpana aniani ʻelua, kahi e hoʻopili ai i ka alignment o nā molekele aniani wai ma waena o lākou, e hoʻohuli ʻia nā koʻokoʻo molekala, a ʻaʻole e lilo ka mālamalama. hiki iā ia ke komo, no laila e ālai ana i ke kumu kukui.ʻO ke ʻano o ka ʻokoʻa māmā-ʻeleʻele i loaʻa ma kēia ʻano ua kapa ʻia ʻo ka twisted nematic field effect, a i ʻole TNFE (twisted nematic field effect) no ka pōkole.ʻO nā hōʻike aniani wai i hoʻohana ʻia i nā huahana uila ʻaneʻane hana ʻia me nā hōʻike aniani wai me ka hoʻohana ʻana i ke kumu o ka hopena nematic field twisted.ʻO ka loina hōʻike o ke ʻano STN ua like.ʻO ka ʻokoʻa, ʻo nā molekole aniani wai o ka TN twisted nematic field effect e hoʻohuli i ke kukui hanana e 90 degere, aʻo ka STN super twisted nematic field effect e hoʻohuli i ka mālamalama hanana e 180 a 270 degere.Pono e wehewehe ʻia ma ʻaneʻi ʻo ka hōʻike aniani wai TN maʻalahi iā ia iho he ʻelua mau hihia o ka mālamalama a me ka ʻeleʻele (a i ʻole ʻeleʻele a keʻokeʻo), a ʻaʻohe ala e hoʻololi ai i ke kala.ʻO nā hōʻike aniani wai STN e pili ana i ka pilina ma waena o nā mea aniani wai a me ke ʻano o ka hoʻopili ʻana o ka mālamalama, no laila ʻo ka hue o ka hōʻike he ʻōmaʻomaʻo māmā a me ka ʻalani.Eia nō naʻe, inā hoʻohui ʻia kahi kānana kala i kahi LCD STN monochrome maʻamau, a ua māhele ʻia kekahi pixel (pixel) o ka matrix hōʻike monochrome i ʻekolu sub-pixels, ua hele nā ​​kānana kala ma o. ʻulaʻula, ʻōmaʻomaʻo, a me ka uliuli, a laila hiki ke hōʻike ʻia ke kala o ke ʻano kala piha ma ka hoʻoponopono ʻana i ka māhele o nā kala kumu ʻekolu.Eia kekahi, ʻoi aku ka nui o ka nui o ka pale o kahi LCD TN-type, ʻoi aku ka haʻahaʻa o ka ʻokoʻa o ka pale, akā me ka ʻenehana i hoʻomaikaʻi ʻia o STN, hiki iā ia ke hana no ka nele o ka ʻokoʻa.
