TFT: Transistor Yopyapyala ya Filimu
LCD: Chiwonetsero cha Makristalo Amadzimadzi
TFT LCD ili ndi magalasi awiri okhala ndi galasi lokhala ndi kristalo wamadzimadzi pakati, limodzi mwa iwo lili ndi TFT ndipo lina lili ndi fyuluta yamtundu wa RGB. TFT LCD imagwira ntchito pogwiritsa ntchito ma transistors a thin-film kuti azitha kuwongolera kuwonekera kwa pixel iliyonse pazenera. Pixel iliyonse imapangidwa ndi ma subpixel ofiira, obiriwira, ndi abuluu, iliyonse ili ndi TFT yakeyake. Ma TFT awa amagwira ntchito ngati ma switch, akuwongolera kuchuluka kwa magetsi omwe amatumizidwa ku sub-pixel iliyonse.
Magalasi awiri: TFT LCD imakhala ndi magalasi awiri okhala ndi galasi lokhala ndi galasi lamadzimadzi pakati pawo. Magalasi awiriwa ndiye kapangidwe kake ka chiwonetserochi.
Matrix ya transistor yopyapyala (TFT): Ili pa galasi, pixel iliyonse ili ndi transistor yopyapyala yofanana. Ma transistor amenewa amagwira ntchito ngati ma switch omwe amayang'anira mphamvu ya pixel iliyonse mu layer yamadzimadzi a crystal.
Madzi a kristalo: Pakati pa magalasi awiri, mamolekyu a kristalo amadzimadzi amazungulira pansi pa mphamvu ya magetsi, yomwe imalamulira kuchuluka kwa kuwala komwe kumadutsa
Fyuluta yamitundu: Ili pa galasi lina, imagawidwa m'ma subpixel ofiira, obiriwira, ndi abuluu. Ma subpixel awa amafanana ndi ma transistors omwe ali mu TFT matrix ndipo pamodzi amasankha mtundu wa chiwonetserocho.
Kuwala kwakumbuyo: Popeza kristalo yamadzimadzi yokha siimatulutsa kuwala, TFT LCD imafuna gwero la kuwala kwakumbuyo kuti iunikire gawo lamadzimadzi la kristalo. Magetsi odziwika bwino ndi LED ndi Cold Cathode Fluorescent Lamps (CCFLs)
Ma Polarizer: Ali mkati ndi kunja kwa magalasi awiri, amalamulira momwe kuwala kumalowera ndi kutuluka mu galasi lamadzimadzi.
Mabodi ndi ma IC oyendetsa: Amagwiritsidwa ntchito kuwongolera ma transistors mu TFT matrix, komanso kusintha mphamvu yamagetsi ya gawo lamadzimadzi la kristalo kuti azitha kuwongolera zomwe zikuwonetsedwa pazenera.
