Tsis zoo li TN tshuab, lub TFT siv siv "rov qab-tob tob" txoj kev-txoj kev xav ntawm txoj kev kaj tsis yog saum toj mus rau hauv qab li TN kua siv lead ua, tab sis txij li hauv qab. Qhov kev qhia no yog los teeb lub raj tshwj xeeb lub teeb nyob sab nraum qab ntawm cov kua siv lead ua kua, lub teeb ci tuaj ntawm sab qaum ntawm lub phaj. Raws li cov electrodes ntawm cov khaubncaws sab nraud povtseg sab nrauv thiab qis dua yuav raug hloov mus rau FET electrodes thiab ib qho ohmic electrode, kev ua haujlwm ntawm cov kua qaub (crystal) yuav hloov thaum lub FET electrode yog cov khoom siv, thiab cov duab yuav ua tiav los ntawm shading thiab lub teeb kis lub sij hawm teb tau zoo heev txog li 80ms. Vim nws zoo dua qhov sib txawv dua TN-LCD thiab richer xim, screen hloov zaus zaus kuj yog sai, yog li TFT nquag hu ua "True Colors." Piv rau DSTN, qhov tseem ceeb ntawm TFT-LCD tseem ceeb yog kho ib qho kev sib txuas lus semiconductor rau txhua lub pixel. Vim tias txhua pixel tuaj yeem tswj tau ncaj qha los ntawm lub plhaub tes. Yog li txhua txoj ntawm kuj ywj siab thiab tswj tau tsis tu ncua. Txoj kev tsim qauv no tsis yog tsuas yog ua kom pom cov vijtsam ceev ceev, tabsis tseem muaj peev xwm tswj tau qhov teebmeem grey level, qhov no yog qhov TFT xim ntau dua li qhov laj thawj.
Hauv TFT-LCD, qhov kev ua haujlwm ntawm TFT yog sib npaug rau cov raj xa mus. Feem ntau siv TFT yog ib qho khoom siv davhlau ya raws peb. Ib semiconductor txheej feem ntau yog qhia ntawm ib lub iav substrate, ntawm ob hnub ntawm qhov twg thiab qhov ntws tawm nrog. Thiab lub qhov rooj ntawm lub qhov rooj thaiv tau txuas nrog lub semiconductor, thiab lub qhov rooj npaj. Qhov tam sim no ntawm lub hauv paus thiab cov pa tawm ntawm cov hluav taws xob yog tswj los ntawm cov hluav taws xob uas siv rau lub qhov rooj. Rau ib cov zaub, txhua pixel yuav ua tau structurally simplified saib lub kua siv lead ua kua ntawm tus pixel electrode thiab ib qho electrode. Nws yog qhov tseem ceeb tshaj rau koj xav txog nws ua lub capacitor ntawm lub kaum ntawm hluav taws xob. Qhov sib npaug ntawm qhov sib npaug yog muaj nyob hauv daim duab 1. Yuav tsum tau them tus nqi P (p, iv) ntawm J Tshooj I kem, hloov T (I, J) . Thaum twg lub pixel electrode yog siab them, txawm tias qhov kev hloov no tau kaw, qhov hluav taws xob nqi hauv lub capacitor yog fwm, thiab cov kua siv lead ua kua ntawm cov electrodes tseem muaj qhov nyhuv voltage field. Kev ua haujlwm ntawm cov ntaub ntawv (sab) tsav yog siv lub hom phiaj ntawm qhov kev sib tw, thaum lub qhov rooj (kab) tsav yog txoj kev xa thiab kev tshem ntawm qhov pib. Vim hais tias cov zaub voltage ntawm cov kua siv lead ua kua tau muab khaws cia rau hauv qhov ua kom muaj peev xwm ntawm txhua lub pixel, cov kua siv lead ua kua tau ua haujlwm ruaj. Qhov tso tawm qhov pom ntawm TFT kuj tuaj yeem raug rov sau dua tshiab nyob rau lub sij hawm luv luv, yog li ntawd hauv lub siab txhais, nws tsis tuaj yeem txo cov duab zoo. Qhov tseem ceeb ntawm cov duab tso duab yog qhov qhia txog molecular orientation ntawm cov kua siv lead ua kua hauv cov hluav taws xob. Feem ntau, qhov kev taw qhia ntawm sab hauv substrate yog kho kom cov txheej txheem ntawm cov kua siv lead ua kua roj ua rau lub qhov dej xav xav kom ua tau ntau hom zaub. Xaiv ib hom zaub, ua haujlwm ua hluav taws xob ua kua, ua kua dej ua kua roj ua rau lub hom phiaj ntawm kev hloov, thiab nrog rau lub Polarizer qhov kev sib tw, ua rau teeb meem lub teeb kis mus dhau lub kua siv lead ua kua zog. Thiaj li paub cov duab saib. Nyob rau hauv ib lo lus, TFT-LCD thiab passive TN-LCD, STN-LCD yooj yooj yim matrix, nws yog nyob rau hauv txhua pixel ntawm lub LCD screen muaj ib zaj duab xis nyias transistor (TFT), muaj peev xwm kov yeej lub crosstalk thaum tsis xaiv, yog li ntawd lub static cov yam ntxwv ntawm cov vijtsam zaub thiab cov naj npawb ntawm cov kab scan, Vim li no, cov duab zoo zoo heev. thiab hloov chav tsev (uas yog, TFT), nws yuav tsum ua kom tau raws li lub xeev tsis kam, lub kaw lus-xeev tsis kam tseem loj heev.
