TFT (Thin Film Transistor) yog ib zaj duab xis tshav ua nyhuv ntawm transistor. Lub npe hu ua nyias zaj duab xis transistor txhais tau hais tias txhua lub kua siv lead ua kua pixel ntawm cov kua siv lead ua kua zaub tau tsav los ntawm nyias zaj duab xis transistor sib txuas tom qab nws. Qhov no tuaj yeem tso saib cov lus qhia txog kev tshuaj ntsuam ntawm kev kub ceev, siab lub teeb ci, thiab lub siab zoo. TFT yog kev ua haujlwm ntawm matrix kua siv lead ua kua zaub.
Lub TFT-LCD kua siv lead ua cov duab yog ib zaj duab xis nyias transistor hom kua siv lead ua kua zaub, tseem hu ua" xim tseeb" (TFT). TFT kua siv lead ua muaj qhov hloov semiconductor rau txhua lub pixel, thiab txhua lub pixel tuaj yeem tswj tau ncaj qha los ntawm dot pulses, yog li txhua lub node muaj feem ywj siab thiab tuaj yeem tswj tau txuas ntxiv, uas tsis tsuas yog txhim kho qhov kev teb ceev ntawm cov zaub, tab sis kuj tuaj yeem ua ncaj qha raug tswj Cov zaub xim ntawm kev qhia, yog li cov xim ntawm TFT kua siv lead ua yog ntau tiag tiag.
Hauv kev sib tw muaj zog ntawm ntau cov vaj huam sib luag tiaj tiaj pom, vim li cas TFT-LCD tuaj yeem sawv tawm thiab dhau los ua cov khoom siv hluav taws xob tshiab txuas ntxiv yog los ntawm tsis muaj kev sib tsoo, nws yog kev tsis tuaj yeem dhau kev txhim kho ntawm tib neeg kev siv tshuab thiab kev xav hom. Cov kua siv hluav taws xob tau zam qhov teeb meem nyuaj teeb meem ua ntu zus, siv cov yam ntxwv zoo ntawm cov kua siv lead ua kua hluav taws xob ua lub teeb valve los rhuav tshem cov teeb pom kev ua kom pom lub teeb ua ob ntu, uas yog lub teeb ci thiab tswj cov khoom siv lub teeb. Raws li lub teeb pom kev zoo, cov txiaj ntsig tau ci tau tiav nyob rau hauv cov lus ntawm luminous efficiency, tag nrho xim, thiab lub neej, thiab lawv tseem tau ua tob. Txij li kev tsim tawm ntawm LCD, lub teeb nrig tau txuas ntxiv txuas ntxiv, los ntawm monochrome mus rau xim, los ntawm tuab mus rau nyias, los ntawm sab teeb fluorescent hom teeb ci rau fluorescent teeb lub teeb. Cov kev ua tiav tshiab hauv kev teeb pom kev zoo yuav muab cov teeb pom kev tshiab tshiab rau LCDs. Nrog kev nce qib ntawm cov khoom siv hluav taws xob tshiab, cov teeb pom kev tshiab tshiab thiab zoo dua yuav tshwm sim thiab siv rau LCDs. Qhov seem yog kev tswj hwm ntawm cov khoom siv hluav taws xob, cov thev naus laus zis thiab cov txheej txheem ntawm cov tshuab hluav taws xob ntau qhov sib xyaw ua ke tau hloov pauv, cov zaj duab xis transistor (TFT) cov txheej txheem ntau lawm tau tiav lawm, lub matrix hais txog kev tswj cov kua siv lead ua kua hluav taws xob lub teeb yog pom tau hais tias, thiab lub teeb ci ntawm cov kua siv lead ua zaub tau daws tau. Qhov kev koom tes ntawm lub valve thiab lub maub los tso cai qhov zoo ntawm cov kua siv lead ua kua los ua kom pom tseeb.
