TFT-LCD cov ntxaij vab tshaus yog hu ua xim LCD cov ntxaij vab tshaus, thiab cov ntxaij vab tshaus ntawm ntau cov khoom siv hluav taws xob yog ua los ntawm cov ntxaij vab tshaus LCD. Yog li koj paub ntau npaum li cas txog nws txoj haujlwm ua haujlwm? Kuv yuav muab ib qho kev qhia dav dav rau koj.
Raws li kev hais lus, cov khoom siv ua kua siv lead ua kua yog cov khoom siv vaj huam sib luag tiaj tiaj nrog lub thickness ntawm li 1 hli. Nws yog tsim los ntawm ob lub polarizers, pem hauv ntej thiab nram qab iav daim hlau, sealing ntug thiab kua siv lead ua kua.
Lub vijtsam LCD nws tus kheej tsis tawm lub teeb, yog li lub vaj huam sib luag luminous backlight tau nruab rau sab nraum qab ntawm LCD npo los muab lub teeb ci. Kev taw qhia ntawm qhov ntev axis ntawm ob txheej ntawm cov kua siv lead ua kua molecules nyob ib sab ntawm lub phaj polarizing yog zoo ib yam nrog cov kev taw qhia polarization ntawm cov phaj polarizing uas nyob ib sab. Cov kua siv lead ua kua molecules nyob ze ntawm lub interlayer sab sauv yog teem rau hauv cov kev taw qhia ntawm lub sab sauv groove, thiab cov kua siv lead ua kua molecules nyob rau hauv qis interlayer yog teem nyob rau hauv cov kev taw qhia ntawm lub qis groove. Thaum kawg, nws tau ntim rau hauv cov kua siv lead ua kua cell.
Yog tias koj zoom rau ntawm koj lub monitor, koj yuav pom ntau txhiab tus liab, ntsuab, thiab xiav dots. Peb qhov me me no ua ib lub pixel, thiab txhua pixel yog tsim los ntawm lub teeb nraub qaum, peb xim lim thiab polarizer. Lub teeb emissions los ntawm lub backlight dhau los ntawm lub parallel thiab ntsug substrates. Thawj polarizer tsuas yog tso cai rau lub teeb kab rov tav hla mus rau lub lim, thaum lwm tus polarizer tsuas yog tso cai rau lub teeb hla dhau ntawm txoj kab ntsug. Thaum ob lub polarizers Thaum ob qho tib si qhib, tsis muaj lub teeb ncav cuag lub lim. Lub sijhawm no, cov kua siv lead ua kua ua lub luag haujlwm. Muaj ob lub electrodes ua ntej thiab tom qab cov kua siv lead ua kua. Raws li ib txwm muaj, qhov kev npaj ntawm cov kua siv lead ua kua yog tsis zoo. Cov electrode tuaj yeem ua kom muaj zog los ua kom cov kev taw qhia ntawm cov kua siv lead ua kua raws li cov kev taw qhia electrode. Nyob rau hauv cov ntaub ntawv no, lub teeb dhau los ntawm cov kua siv lead ua kua yuav tsis yog biased. Thaum cov kua siv lead ua kua no tso rau hauv cov pixels, lub teeb los ntawm lub teeb rov qab yuav dhau los ntawm cov kab rov tav lim thiab ua rau cov kua siv lead ua kua, thiab tom qab ntawd ncav cuag los ntawm ntsug polarizer. Xim lim. Yog tias cov hluav taws xob tau qhib dua, lub teeb tsis ncaj ncees, thiab ntsug polarizer yuav thaiv lub teeb kom nws tsis tuaj yeem hla. Los ntawm kev kho lub zog ntawm txhua txheej ntawm electrodes, lub teeb ci ntawm lub lim tuaj yeem ncav cuag los tswj cov xim ntawm cov zaub. Yog li peb tuaj yeem pom daim duab ntawm lub monitor.
