Txog TFT-LCD (Thin Film Transistor Liquid Crystal Display) Kev Taw Qhia Txog Qauv

Ob lub iav substrates: TFT LCD muaj ob lub iav substrates nrog ib txheej kua siv lead ua kua nyob nruab nrab ntawm lawv. Ob lub substrates no yog cov qauv tseem ceeb ntawm cov zaub.

Cov transistor nyias nyias (TFT) matrix: Nyob rau ntawm lub iav substrate, txhua pixel muaj ib lub transistor nyias nyias sib xws. Cov transistors no ua haujlwm ua cov keyboards uas tswj lub zog ntawm txhua pixel hauv cov kua siv lead ua kua.

Txheej siv lead ua kua: Nyob nruab nrab ntawm ob lub iav substrates, cov molecule siv lead ua kua tig raws li qhov kev ua ntawm lub teb hluav taws xob, uas tswj qib ntawm lub teeb hla dhau.

Lim xim: Nyob rau ntawm lwm lub iav substrate, nws yog muab faib ua liab, ntsuab, thiab xiav subpixels. Cov subpixels no sib raug ib-rau-ib rau cov transistors hauv TFT matrix thiab ua ke txiav txim siab xim ntawm qhov screen.

Teeb Pom Kev: Vim tias cov kua siv lead ua kua tsis tso tawm lub teeb, TFT LCD xav tau lub teeb pom kev los ci cov txheej siv lead ua kua. Cov teeb pom kev feem ntau yog LED thiab Cold Cathode Fluorescent Lamps (CCFLs).

Cov Polarizers: Nyob rau sab hauv thiab sab nraud ntawm ob lub iav substrates, lawv tswj txoj kev uas lub teeb nkag thiab tawm hauv cov kua siv lead ua kua.

Cov laug cam thiab cov tsav tsheb ICs: Siv los tswj cov transistors hauv TFT matrix, nrog rau kho qhov voltage ntawm cov kua siv lead ua kua los tswj cov ntsiab lus tso tawm ntawm qhov screen.
