TFT: Thin Film Transistor
LCD: Liquid Crystal Display
TFT LCD muaj ob lub iav substrates nrog cov kua siv lead ua kua txheej sandwiched nyob nruab nrab ntawm, ib qho muaj TFT rau nws thiab lwm yam muaj RGB xim lim. TFT LCD ua haujlwm los ntawm kev siv cov yeeb yaj kiab nyias nyias los tswj cov zaub ntawm txhua pixel ntawm qhov screen. Txhua pixel yog tsim los ntawm liab, ntsuab, thiab xiav subpixels, txhua tus muaj nws tus kheej TFT. Cov TFTs no ua haujlwm zoo li cov keyboards, tswj qhov hluav taws xob ntau npaum li cas xa mus rau txhua qhov sub-pixel.
Ob lub iav substrates: TFT LCD muaj ob lub iav substrates nrog cov kua siv lead ua kua txheej sandwiched ntawm lawv. Ob lub substrates no yog cov qauv tseem ceeb ntawm cov zaub.
Thin-film transistor (TFT) matrix: Nyob rau ntawm lub iav substrate, txhua pixel muaj ib tug sib xws nyias-film transistor. Cov transistors ua raws li cov keyboards uas tswj qhov voltage ntawm txhua pixel hauv cov kua siv lead ua kua txheej.
Cov kua siv lead ua kua: Nyob nruab nrab ntawm ob lub iav substrates, cov kua siv lead ua kua molecules tig nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, uas tswj cov qib ntawm lub teeb hla.
Xim lim: Nyob ntawm lwm lub iav substrate, nws muab faib ua liab, ntsuab, thiab xiav subpixels. Cov subpixels sib txuas ib-rau-ib rau cov transistors hauv TFT matrix thiab ua ke txiav txim siab xim ntawm cov zaub.
Backlight: Txij li cov kua siv lead ua kua nws tus kheej tsis tawm lub teeb, TFT LCD xav tau lub teeb pom kev zoo los teeb lub kua siv lead ua kua. Cov teeb pom kev zoo yog LED thiab Cold Cathode Fluorescent Teeb (CCFLs)
Polarizers: Nyob rau sab hauv thiab sab nraud ntawm ob lub iav substrates, lawv tswj txoj kev lub teeb nkag mus thiab tawm ntawm cov kua siv lead ua kua.
Boards thiab tsav tsheb ICs: Siv los tswj cov transistors hauv TFT matrix, nrog rau kev kho qhov voltage ntawm cov kua siv lead ua kua txheej los tswj cov ntsiab lus pom ntawm lub vijtsam.
