Zokambirana zaposachedwa zamakampani zakhudza kwambiri ukadaulo waukulu waTransistor Yopyapyala (TFT) lmawonedwe a makristalo a iquid, kuwonetsa njira yake yowongolera "yogwira ntchito" yomwe imalola kujambula zithunzi molondola kwambiri—kupambana kwasayansi komwe kumayendetsa zochitika zamakono zowonera.
TFT, mwachidule cha Thin-Film Transistor, imatanthauza matrix ya ma transistors ang'onoang'ono. Mosiyana ndi zowonetsera zachikhalidwe, pixel iliyonse muTFTChophimbacho chimayendetsedwa payekhapayekha kudzera mu dongosolo la "active matrix". Mfundo yogwirira ntchito ikufanana ndi njira ya "shutter": pogwiritsa ntchito ukadaulo wa backlight, ma transistors odzipereka kumbuyo kwa pixel iliyonse amawongolera kutumiza kwa kuwala mwa kusintha mawonekedwe a kristalo wamadzimadzi, kuti apange mtundu woyenera komanso kutulutsa kuwala.
Zamatsenga zaMa LCD Owonetsera Madzi (Ma Crystal Displays)Ili m'gulu la zinthu zapadera za makhiristo amadzimadzi. Ili m'magulu atatu akuluakulu—smectic (zigawo zonga dongo), nematic (mamolekyulu ooneka ngati ndodo), ndi cholesteric (yozungulira)—Ma TFT LCDKawirikawiri amagwiritsa ntchito makristalo a nematic. Magetsi akagwiritsidwa ntchito, makristalo awa amapotoza momwe amayendera mamolekyu kuti azitha kuyendetsa kuwala. Pixel iliyonse imaphatikiza ma subpixel ofiira, obiriwira, ndi abuluu, zomwe zimapangitsa kuti mitundu yowonjezereka isakanike kuti ipange zithunzi zowoneka bwino.
Twisted Nematic (TN) yomwe imagwiritsidwa ntchito kwambiriTFT LCDukadaulo, wodziwika chifukwa cha kuyankha mwachangu komanso kudalirika kwake, umalimbikitsa zida zazikulu kuyambira mafoni a m'manja mpaka ma TV. Pamene zatsopano zowonetsera zosinthika zikupita patsogolo, TFT yakonzeka kusintha magawo atsopano monga ukadaulo wovalidwa, ndikulonjeza zowonera zopyapyala komanso zopindika kuti zigwiritsidwe ntchito m'badwo wotsatira.
