Hōʻikeʻike LCD Matrix 128×64, Hōʻikeʻike LCD Fstn, Hōʻikeʻike LCD STN 128×64,

1, He aha ka TN LCD?

ʻO TN LCD (Twisted Nematic Liquid Crystal Display) kahi ʻano ʻenehana LCD i hoʻohana pinepine ʻia i nā hōʻike kikohoʻe, nā kīwī, nā monitor kamepiula, a me nā polokalamu kelepona. Ua kaulana ia no kona manawa pane wikiwiki, ka ʻōlinolino kiʻekiʻe, a me nā kumukūʻai hana haʻahaʻa. Hoʻohana nā TN LCD i nā molekala kristal wai e wili ana i kahi hoʻonohonoho wili ke hoʻopili ʻia kahi au uila iā lākou. Hoʻohana nui ʻia kēia ʻano ʻenehana LCD ma muli o kona kumukūʻai kūpono, akā hāʻawi pinepine ia i nā kihi nānā palena a me ka pololei o ke kala haʻahaʻa i hoʻohālikelike ʻia me nā ʻenehana LCD ʻē aʻe e like me IPS (In-Plane Switching) a me VA (Vertical Alignment).

2, He aha ka STN LCD?

ʻO STN LCD (Super-Twisted Nematic Liquid Crystal Display) kahi ʻano ʻenehana LCD he holomua o TN LCD. Hoʻomaikaʻi ia i nā hiki ke kala a me ke ʻano like ʻole o nā TN LCD, me ka hāʻawi pū ʻana i ka hoʻohana ʻana i ka mana haʻahaʻa. Hoʻohana nā STN LCD i kahi ʻano nematic super-twisted e hiki ai ke kaohi maikaʻi i nā molekala kristal wai, e hopena ana i ka maikaʻi o ke kiʻi. Hoʻokumu ka ʻano nematic super-twisted i kahi hoʻonohonoho helical o nā kristal wai, e kōkua ana i ka hoʻonui ʻana i nā kihi nānā o ka hōʻike a hāʻawi i nā pae kiʻekiʻe o ke ʻano like ʻole a me ka saturation kala. Hoʻohana pinepine ʻia nā STN LCD i nā mea hana e like me nā calculators, nā uaki kikohoʻe, a me kekahi mau kelepona paʻalima hanauna mua. Eia nō naʻe, ua hoʻopau nui ʻia e nā ʻenehana LCD holomua e like me TFT (Thin Film Transistor) a me IPS (In-Plane Switching).

3, He aha ka FSTN LCD?

ʻO ka FSTN LCD (Film-compensated Super Twisted Nematic Liquid Crystal Display) kahi mana i hoʻomaikaʻi ʻia o ka ʻenehana STN LCD. Hoʻohana ia i kahi papa uku kiʻiʻoniʻoni e hoʻomaikaʻi i ka hana o ka hōʻike. Hoʻohui ʻia ka papa uku kiʻiʻoniʻoni i ka ʻōnaehana STN LCD e hōʻemi i ka pilikia hoʻohuli hina hina e kū pinepine ana i nā hōʻike STN kuʻuna. ʻO kēia pilikia hoʻohuli hina hina e alakaʻi ai i ka emi ʻana o ke ʻano like ʻole a me ka ʻike ʻana i ka wā e nānā ana mai nā kihi like ʻole.
Hāʻawi nā FSTN LCD i nā lakio ʻokoʻa i hoʻomaikaʻi ʻia, nā kihi nānā ākea, a me ka hana hōʻike ʻoi aku ka maikaʻi ma mua o nā STN LCD. Hiki iā lākou ke hōʻike i nā kiʻi maikaʻi a maikaʻi ʻole ma ka hoʻoponopono ʻana i ke ana uila i hoʻopili ʻia i nā cell kristal wai. Hoʻohana pinepine ʻia nā FSTN LCD i nā noi kahi e pono ai ke ʻano ʻokoʻa kiʻekiʻe a me nā kihi nānā maikaʻi, e like me nā uaki akamai, nā panela hoʻomalu ʻoihana, a me nā mea lapaʻau.

4, He aha ka VA LCD?

ʻO VA LCD ke kū nei no Vertical Alignment Liquid Crystal Display. He ʻano ʻenehana LCD ia e hoʻohana ana i nā molekala kristal wai i hoʻonohonoho ʻia i luna e kaohi i ka hele ʻana o ke kukui.
I loko o kahi VA LCD, hoʻonohonoho pololei nā mole kristal wai iā lākou iho ma waena o ʻelua mau substrates aniani ke ʻole ka voltage e hoʻopili ʻia. Ke hoʻopili ʻia kahi voltage, wili nā mole e hoʻonohonoho ākea, e ālai ana i ke hele ʻana o ke kukui. ʻO kēia neʻe wili e hiki ai i nā VA LCD ke kāohi i ka nui o ke kukui e hele ana a pēlā e hana ai i nā pae ʻokoʻa o ka mālamalama a i ʻole ka pouli.

ʻO kekahi o nā pono nui o ka ʻenehana VA LCD ʻo ia kona hiki ke hoʻokō i nā lakio ʻokoʻa kiʻekiʻe. ʻO nā molekala kristal wai i hoʻonohonoho pono ʻia a me ka kaohi ʻana o ka hele ʻana o ka mālamalama e hopena i nā ʻeleʻele hohonu a me nā keʻokeʻo ʻoi aku ka mālamalama, e alakaʻi ana i kahi hōʻike ʻoi aku ka ola a me ke ola maoli. Hāʻawi pū nā VA LCD i nā kihi nānā ākea i hoʻohālikelike ʻia me nā LCD TN (Twisted Nematic), ʻoiai ʻaʻole paha lākou e kūlike me nā kihi nānā o nā LCD IPS (In-Plane Switching).

Ma muli o ko lākou mau lakio ʻokoʻa maikaʻi loa, ka hana hou ʻana o ke kala maikaʻi, a me nā kihi nānā ākea, hoʻohana pinepine ʻia nā VA LCDs i nā kīwī kiʻekiʻe a me nā monitor kamepiula, a me kekahi mau polokalamu kelepona, nā consoles pāʻani, a me nā hōʻike kaʻa.
