TFT-LCD kua siv lead ua kua zaub yog ib qho nyias-zaj duab xis transistor hom kua siv lead ua kua zaub, uas yog xim tseeb (TFT), yog li muaj lub sij hawm TFT kua siv lead ua xim tseeb xim.
TFT LCD muaj tseeb xim tshuaj ntsuam yog nruab nrog ib tug semiconductor hloov rau txhua pixel, thiab txhua pixel tuaj yeem tswj tau ncaj qha los ntawm dot pulses, yog li txhua lub node yog tus kheej ywj pheej thiab tuaj yeem tswj tsis tu ncua, uas tsis tsuas yog txhim kho cov lus teb ceev ntawm cov zaub, tab sis kuj Precisely tswj cov zaub xim gradation, yog li cov xim ntawm TFT LCD muaj tseeb xim tshuaj ntsuam ntau muaj tseeb.
TFT LCD cov ntxaij vab tshaus xim muaj tseeb muaj qhov ci ci zoo, qhov sib txawv siab, muaj zog txheej, thiab cov xim ci, tab sis lawv kuj muaj qhov tsis zoo ntawm kev siv hluav taws xob thiab tus nqi siab.
TFT LCD thev naus laus zis tau nrawm rau txoj kev loj hlob ntawm cov xov tooj ntawm tes xim cov ntxaij vab tshaus. Lub cim tshiab ntawm TFT cov ntxaij vab tshaus muaj tseeb txhua qhov txhawb 65536 xim, thiab qee qhov txawm txhawb 160,000 xim. Lub sijhawm no, qhov zoo ntawm TFT qhov zoo sib xws thiab cov xim nplua nuj yog qhov tseem ceeb heev.
Lub ntsiab qauv ntawm TFT muaj tseeb xim tshuaj ntsuam yog fluorescent raj, lub teeb qhia phaj, polarizing phaj, lim phaj, iav substrate, alignment film, kua siv lead ua khoom, nyias hom transistor thiab hais txog.
TFT, los yog nyias zaj duab xis teb cov nyhuv transistor, yog ib hom active matrix kua siv lead ua zaub. Nws tuaj yeem "qhib" tswj txhua tus pixel ntawm lub vijtsam, uas tuaj yeem txhim kho lub sijhawm teb zoo heev.
Feem ntau, lub sij hawm teb ntawm TFT yog ceev ceev, txog 80 milliseconds, thiab lub kaum sab xis saib yog loj, feem ntau ncav cuag li 130 degrees, uas yog siv nyob rau hauv high-end khoom. Lub thiaj li hu ua nyias zaj duab xis teb nyhuv transistor txhais tau hais tias txhua cov kua siv lead ua pixel ntawm cov kua siv lead ua kua yog tsav los ntawm nyias zaj duab xis transistor ua ke tom qab ntawd.
Qhov no tuaj yeem tso saib cov ntaub ntawv tshuaj ntsuam ntawm kev kub ceev, siab ci, thiab qhov sib txawv siab. Lub TFT tseeb xim tshuaj ntsuam belongs rau lub active matrix kua siv lead ua zaub, uas yog technically tsav los ntawm "active matrix" txoj kev. Cov txheej txheem yog siv cov cuab yeej ua yeeb yaj kiab nyias los ua cov transistor electrode, thiab siv cov txheej txheem scanning los "kho kom nquag plias" los tswj txhua qhov taw qhia. Thaum lub teeb ci nyob rau hauv thiab tawm, lub teeb ci ua ntej nkag mus rau sab saud ntawm lub phaj polarizing qis, thiab lub teeb kis tau los ntawm cov kua siv lead ua kua molecules, thiab lub hom phiaj ntawm cov zaub yog ua tiav los ntawm shading thiab xa lub teeb.
