Dab Tsi Koj Thiaj Li Paub TN Pawg Neeg

Sep 04, 2019

Feem ntau cov saib pom niaj hnub no siv lub Twisted Nematic (TN) LCD vaj huam sib luag. Qhov kom zoo dua ntawm cov thev naus laus zis LCD tshuab yog tias nws pheej yig los tsim thiab tias TN vaj huam sib luag tuaj yeem hloov pauv lub xeev sai, muab lawv lub sijhawm teb zoo tshaj plaws ntawm txhua qhov muaj LCD thev naus laus zis. Qhov no ua rau cov panels tsim nyog dua rau kev ua si uas muaj kev hloov duab nrawm. Ua tsaug rau kev sib koom ua ke ntawm tus nqi qis thiab teb sai lub sijhawm, TN cov lus yog deb tshaj plaws niaj hnub no.


TN LCD Ua Haujlwm Li Cas?

Qhov nrhiav pom ntawm TN cov txiaj ntsig yog qhov hloov kho hauv flat screen technology thiab rau txhua qhov kev nkag siab thiab lub hom phiaj yog nws yog dab tsi coj LCD technology rau hauv kev pib siv. Cov nyhuv txhais tau tias cov kua siv lead ua kua tau tswj hwm thiab rov tsim kho mus rau hauv cov txheej txheem sib txawv lwg me me hauv qab ntawm hluav taws xob teb. Nws yuav tsum tau hais tias cov kua siv ua kua tuaj yeem tig ntawm "on" thiab "off" states. Qhov no tau ua tiav los ntawm kev cia cov tam sim no dhau los ntawm txheej txheej zaj duab xis (yog li lub npe hu ua Thin Film Transistor, lossis TFT). Twisting nws 90 degrees cia tsis muaj lub teeb pom kev dhau los, hos lwm lub xeev cia txawm tias cov kev ncua xim xim liab, ntsuab lossis xiav (RGB). Yog hais tias tus liab, ntsuab thiab xiav sub-pixels yog tag nrho cov lit, lub pixel hloov dawb.
