TFT: Thin Film Transistor
LCD: Liquid Crystal Display
TFT LCD imakhala ndi magawo awiri agalasi okhala ndi kristalo wamadzimadzi wopindika pakati, imodzi yomwe ili ndi TFT ndipo inayo ili ndi zosefera zamtundu wa RGB. TFT LCD imagwira ntchito pogwiritsa ntchito ma transistors amafilimu opyapyala kuwongolera ma pixel aliwonse pazenera. Pixel iliyonse imapangidwa ndi ma subpixel ofiira, obiriwira, ndi abuluu, iliyonse ili ndi TFT yake. Ma TFT awa amachita ngati masiwichi, kuwongolera kuchuluka kwa magetsi omwe amatumizidwa ku pixel iliyonse.
Magawo awiri agalasi: TFT LCD imakhala ndi magawo awiri agalasi okhala ndi kristalo wamadzimadzi pakati pawo. Magawo awiriwa ndi gawo lalikulu lachiwonetsero.
Thin-film transistor (TFT) matrix: Yopezeka pagawo lagalasi, pixel iliyonse imakhala ndi transistor yofananira ndi filimu yopyapyala. Ma transistors awa amakhala ngati masiwichi omwe amawongolera ma voliyumu a pixel iliyonse mumadzi amadzimadzi.
Liquid crystal layer: Ili pakati pa magawo awiri agalasi, mamolekyu amadzimadzi amadzimadzi amazungulira pansi pa gawo lamagetsi, lomwe limawongolera kuchuluka kwa kuwala komwe kumadutsa.
Zosefera zamitundu: Yopezeka pagawo lina lagalasi, imagawidwa kukhala ma subpixel ofiira, obiriwira, ndi abuluu. Ma subpixels awa amafanana ndi amodzi ndi amodzi kwa ma transistors mu TFT matrix ndipo palimodzi amazindikira mtundu wa chiwonetserocho.
Kuwala kwapambuyo: Popeza kristalo wamadzimadzi pawokha satulutsa kuwala, TFT LCD imafunikira gwero lowunikira kumbuyo kuti iwunikire wosanjikiza wa kristalo wamadzi. Nyali zakumbuyo zodziwika bwino ndi nyali za LED ndi Cold Cathode Fluorescent (CCFLs)
Zopangira polarizer: Zokhala mkati ndi kunja kwa magawo awiri agalasi, zimawongolera momwe kuwala kumalowera ndikutuluka mu kristalo wamadzimadzi.
Ma board ndi oyendetsa ma IC: Amagwiritsidwa ntchito kuwongolera ma transistors mu TFT matrix, komanso kusintha voteji yamadzimadzi a crystal wosanjikiza kuwongolera zomwe zikuwonetsedwa pazenera.
