1, He aha ka TN LCD?

ʻO TN LCD (Twisted Nematic Liquid Crystal Display) he ʻano o ka ʻenehana LCD i hoʻohana mau ʻia i nā hōʻike kikohoʻe, nā kīwī, nā nānā kamepiula, a me nā polokalamu kelepona.Ua ʻike ʻia no kona mau manawa pane wikiwiki, ʻālohilohi kiʻekiʻe, a me nā kumukūʻai hana haʻahaʻa.Hoʻohana nā LCD TN i nā molekole aniani wai e hoʻololi i kahi hoʻonohonoho wili i ka wā e hoʻopili ʻia ai kahi au uila iā lākou.Hoʻohana nui ʻia kēia ʻano ʻenehana LCD ma muli o kona hiki ke loaʻa, akā hāʻawi maʻamau ia i nā kihi nānā liʻiliʻi a me ka pololei o ka waihoʻoluʻu 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) he ʻano o ka ʻenehana LCD kahi holomua o TN LCD.Hoʻomaikaʻi ia ma luna o ke kala a me ka ʻokoʻa o nā LCD TN, ʻoiai e hāʻawi ana i ka hoʻohana haʻahaʻa haʻahaʻa.Hoʻohana ʻo STN LCD i kahi ʻano nematic super-twisted e hiki ai ke hoʻomalu maikaʻi i nā molekala aniani wai, e hopena i ka maikaʻi o ke kiʻi.Hoʻokumu ka ʻōnaehana nematic super-twisted i kahi hoʻolikelike helical o nā kristal wai, e kōkua ana i ka hoʻomaikaʻi ʻana i nā kihi nānā o ka hōʻike a hāʻawi i nā kiʻekiʻe kiʻekiʻe o ka ʻokoʻa a me ka saturation kala.Hoʻohana maʻamau ʻia nā STN LCDs i nā polokalamu e like me nā calculators, nā wati kikohoʻe, a me kekahi mau kelepona hele mua.Eia naʻe, ua hoʻopau ʻia e nā ʻenehana LCD ʻoi aʻe e like me TFT (Thin Film Transistor) a me IPS (In-Plane Switching).

3, He aha ka FSTN LCD?

ʻO FSTN LCD (Film-compensated Super Twisted Nematic Liquid Crystal Display) he mana i hoʻomaikaʻi ʻia o ka ʻenehana LCD STN.Hoʻohana ʻo ia i kahi papa uku kiʻiʻoniʻoni e hoʻomaikaʻi i ka hana o ka hōʻike.Hoʻohui ʻia ka papa uku kiʻiʻoniʻoni i ka STN LCD structure e hōʻemi i ka pilikia hoʻohuli ʻana i ka unahi hina hina e ʻike pinepine ʻia i nā hōʻike STN kuʻuna.Ke alakaʻi nei kēia pilikia hoʻohuli ʻana i ka unahi hina hina i ka hōʻemi ʻana i ka ʻokoʻa a me ka ʻike ke nānā ʻia mai nā kihi ʻokoʻa.
Hāʻawi nā LCD FSTN i nā ratio like ʻole, ʻoi aku ka nui o nā kihi nānā, a me ka hana hōʻike maikaʻi aʻe i hoʻohālikelike ʻia me nā LCD STN.Hiki iā lākou ke hōʻike i nā kiʻi maikaʻi a maikaʻi ʻole hoʻi ma ka hoʻoponopono ʻana i ka volta i hoʻopili ʻia i nā ʻāpana aniani wai.Hoʻohana maʻamau ʻia nā LCD FSTN i nā noi kahi e koi ʻia ai ka ʻokoʻa kiʻekiʻe a me nā kihi nānā maikaʻi, e like me nā wati akamai, nā paneli mana ʻoihana, a me nā mea lapaʻau.

4, He aha ka VA LCD?

Kū ka VA LCD no Vertical Alignment Liquid Crystal Display.He ʻano ia o ka ʻenehana LCD e hoʻohana ana i nā molekele aniani wai e hoʻomalu i ka hele ʻana o ka mālamalama.
I loko o kahi VA LCD, hoʻolikelike nā molekala aniani wai iā lākou iho ma waena o ʻelua mau pani aniani ke hoʻohana ʻole ʻia ka uila.Ke hoʻohana ʻia ka volta, wili nā molekala e hoʻopololei i ka ʻaoʻao, e ālai ana i ka hele ʻana o ka mālamalama.ʻO kēia neʻe wili e hiki ai iā VA LCDs ke hoʻomalu i ka nui o ka mālamalama e hele a no laila e hana i nā pae like ʻole o ka mālamalama a i ʻole ka pouli.

ʻO kekahi o nā pōmaikaʻi koʻikoʻi o ka ʻenehana VA LCD ʻo kona hiki ke hoʻokō i nā lakio hoʻohālikelike kiʻekiʻe.ʻO nā molekele wai aniani i hoʻopaʻa ʻia a me ka hoʻomalu ʻana i ka ala māmā e hopena i nā ʻeleʻele hohonu a me nā keʻokeʻo keʻokeʻo, e alakaʻi ana i kahi hōʻike ʻoi aku ka ikaika a me ke ola.Hāʻawi pū nā VA LCD i nā kihi ʻike ākea e hoʻohālikelike ʻia me TN (Twisted Nematic) LCD, ʻoiai ʻaʻole like lākou me nā kihi nānā o IPS (In-Plane Switching) LCDs.

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