TFT (nyias-zaj duab xis transistor) cov lus qhia yog nquag-Matrix LCDs nrog cov ntxaij vab tshaus puv RGB. Cov ntxaij vab tshaus feature ci ntsa iab, cov xim thiab muaj peev xwm los qhia cov duab animations sai, cov duab sib xyaw ua ke thiab cov ntawv sau yooj yim. TFTS yog cov lus qhia zoo meej rau kev muab tus neeg siv nplua nuj interface rau txhua hom khoom. Thaum ib txwm siv hauv cov khoom siv cov khoom siv zoo li DVD tus kheej thiab cov khoom siv xuas tes ua, TFTS kuj zoo rau kev siv khoom.
TFT yog Active-Matrix LCDs uas muaj me me hloov cov transistors thiab capacitors. Cov trantors me me no tswj txhua pixel ntawm cov zaub thiab yuav tsum muaj lub zog me me kom nquag hloov cov kev qhia ua kua crystal hauv cov zaub. Qhov no tso cai rau kev tswjhwm ceev dua ntawm txhua tus liab, ntsuab thiab xiav cell-pixel cell yog li ua kom pom tseeb nrawm-txav xim duab.
Cov transistors hauv TFT tau npaj nyob rau hauv ib tug matrix ntawm lub iav substrate. Txhua tus pixel ntawm cov zaub tseem tab tom tawm kom txog thaum muaj kev thov them tus nqi rau tus transistor. Tsis zoo li pa tawm passive passive-matrix qhia tawm, txhawm rau qhib ib kab lus meej, cov kab sib piv yog muab rau thiab ib tus nqi xa tuaj tso cov ntawv kom raug. Qhov no yog qhov twg tsuas yog tus capacitor ntawm cov kev xaiv pixel tau txais kev them nqi thiab muaj kom txog thaum lub voj voog tshiab tom ntej. Qhov tseem ceeb, txhua tus transistor ua raws li tus nquag hloov. Los ntawm kev sib xyaw ua ke hloov, cov txwv no cov kab ntawm scan kab thiab tshem tawm cov teeb meem hla kev.
Qhov teeb meem tseem ceeb nrog tn zaj yeeb yaj kiab thev naus laus zis yog qhov kev saib xyuas zoo nkauj, thiab qhov no pom tseeb los ntawm cov duab loj heev ntawm cov duab yog tias koj saib ntawm qhov screen los ntawm hauv qab no. Qhov txawv thiab xim laus xim hloov tuaj yeem pom tseeb nrog txawm tias qhov chaw me me tawm, thiab qhov no yog qhov tsis zoo hauv TN niaj hnub zaj duab xis panels. Qee cov ntawv zaj duab xis tn zoo dua li lwm tus thiab muaj kev txhim kho ntau xyoo, tab sis lawv tseem muaj ntau qhov kev pom dua lwm cov vaj huam sib luag.
