Muaj ntau ntau yam khoom siv rau cov ntxaij vab tshaus LCD. Ntawm ntau hom LCD panels, TN LCD panels yog siv ntau tshaj. VA LCD thiab lwm yam khoom siv kuj yuav siv tau. Yog li dab tsi yog qhov txawv ntawm TN screen thiab VA screen? Cov hauv qab no yuav raug qhia los ntawm LCD LCD npo manufacturers:
1. Ntau hom
VA screen yog hom nrov tshaj plaws ntawm high-end LCD vaj huam sib luag. Nws yog lub vaj huam sib luag pom dav. Nws yog siv ntev rau kev ua txhaum cai tso saib. Cov xim tom qab yog dub. Xim npo luam ntawv kuj tuaj yeem muab ntxiv raws li cov xim ntu code zaub.
TN npo yog Twisted Nematic (twisted nematic) vaj huam sib luag, ib hom kev tshuaj ntsuam, feem ntau siv rau cov khoom ntu.
2. Cov yam ntxwv sib txawv
Qhov sib piv ntawm VA pem hauv ntej yog qhov siab tshaj plaws, tab sis qhov sib xws ntawm qhov screen tsis zoo txaus, thiab xim drift feem ntau tshwm sim, tab sis qhov sib piv dub thiab dawb yog qhov siab heev.
TN cov ntxaij vab tshaus yog pheej yig los tsim thiab yog cov feem ntau siv nkag-qib LCD panels. Tam sim no, lawv tau siv dav hauv cov khoom siv qis kawg LCD ntawm kev ua lag luam. TN LCD npo yog tus cwj pwm los ntawm kev ceev deflection ceev ntawm cov kua siv lead ua kua molecules, yog li lub sij hawm teb yog ceev heev.
3. Sib txawv saib lub kaum sab xis
Lub VA LCD npo yog qhov theoretically ib lub vijtsam puv npo LCD, thiab nws yuav tsim lub kaum sab xis me me thiab tuag lub kaum ntse ntse raws li tus kheej lub kaum ntse ntse ntawm tus neeg soj ntsuam.
Lub kaum sab xis saib ntawm TN npo yog qhov nqaim, feem ntau tsuas yog 30 °, thiab feem ntau yog siv rau cov lus qhia yooj yim xws li khoos phis tawj lossis moos.
Los ntawm kev sib piv saum toj no, peb twb pom qhov txawv ntawm TN screen thiab VA ntawm lub LCD vaj huam sib luag. Qhov tseem ceeb tshaj plaws yog xaiv cov iav LCD tsim nyog raws li koj tus kheej xav tau, thiab xaiv hom kom raug raws li kev siv tiag tiag.
