STN sawv cev rau: Super Twisted Nematic (STN) zaub. Raws li lub npe qhia, "Super Twisted" txhais tau hais tias lub kaum sab xis ntawm kev hloov pauv loj heev, tshaj 90 degrees. Qhov no yog hom dot matrix npo uas tam sim no siv ntau zaus. Peb txhua tus paub tias cov lus teb electro-optical nkhaus ntawm TN hom thiab feem ntau lwm hom kua siv lead ua kua zaub tsis txaus, raws li qhia hauv daim duab hauv qab no:
Daim duab-TN-hom kua siv lead ua kua zaub teb nkhaus
Raws li tuaj yeem pom los ntawm daim duab hauv qab no, raws li kev tsav tsheb nce ntxiv, nws cov lus teb electro-optic maj mam nce, thiab cov yam ntxwv ntawm qhov pib tsis pom tseeb. Qhov no ua rau muaj teeb meem loj heev rau kev tsav tsheb ntau ntau, ua rau cov kua siv lead ua kua tso rau hauv cov ntaub ntawv loj, Cov duab yeeb yaj kiab raug txwv.
Thaum xyoo 1980s, tib neeg tau pom cov khoom siv ua kua siv lead ua kua (TN), uas tsuas yog yuav tsum tau nce lub kaum sab xis ntawm nws cov kua siv lead ua kua molecules los txhim kho nws cov yam ntxwv ntawm kev tsav tsheb. Los ntawm kev siv zog tas mus li, tib neeg tau ua tiav cov khoom siv ua kua siv lead ua kua uas muaj lub kaum ntse ntse tshaj 90 ° rau TN. Peb feem ntau hu rau hom kua siv lead ua kua zaub ntaus ntawv nrog lub kaum sab xis ntawm 180 ° ~ 360 ° raws li super twist (STN) series. Cov khoom.
Tam sim no yuav luag tag nrho cov dot matrix cov duab thiab feem ntau dot matrix cim LCD cov ntxaij vab tshaus tau txais hom STN. STN' s thev naus laus zis twb dhau los ua tiav thiab ua tiav theem hauv LCD kev lag luam. Cov khoom qauv ntawm STN hom yog qhov pib zoo ib yam li ntawm TN hom, tshwj tsis yog tias cov txheej txheem ntawm cov kua siv lead ua kua molecules nyob rau hauv lub cell tsis twisted raws 90 °, tab sis 180 ° ~ 360 °, raws li qhia hauv daim duab 2 hauv qab no.
