Vim li cas peb thiaj nyiam VA cov khoom lag luam rau cov khoom tsis zoo hauv kev txhim kho ntawm ntu ntu cov ntxaij vab tshaus?

Feem ntau, nyob rau theem pib ntawm txoj kev loj hlob, engineers xaiv LCD cov ntxaij vab tshaus rau cov ntaub ntawv pom. Ntawm lawv, rau cov khoom siv hauv tsev me thiab lwm yam khoom siv nrog cov duab digital, 7 ntu lcd cov ntxaij vab tshaus feem ntau yog thawj qhov kev xaiv. Txhawm rau kom ntseeg tau tias tag nrho kev sib haum xeeb ntawm cov khoom, peb feem ntau txiav txim siab cov nyhuv lcd ua ntej.
Cov zaub zoo lcd txhais tau hais tias lub pixel yog pob tshab thaum tsis muaj qhov hluav taws xob thiab opaque thaum lub teeb, ua rau lub lcd cov nyhuv ntawm cov cim dub ntawm keeb kwm dawb.
Tsis zoo lcd zaub txhais tau hais tias lub pixel yog opaque thaum tsis muaj qhov hluav taws xob thiab pob tshab thaum teeb, ua rau muaj cov nyhuv ntawm cov cim dawb ntawm keeb kwm dub (feem ntau nrog backlight).
Txawm li cas los xij, lub lcd zaub nyhuv ntawm cov khoom sib txawv txawv. TN / HTN lcd muaj qhov sib piv qis dua, nrog cov xim dub tsis sib sib zog nqus txaus thiab ua rau grey. Feem ntau, tsuas yog cov duab tshwm sim ntawm 6 teev kev taw qhia yog qhov zoo, thaum lwm cov ces kaum yuav pom cov xim tsis zoo lossis dawb - tawm. Cov lus teb ceev ceev, ua rau nws haum rau cov lus yooj yim digital thiab cim lcd.
VA LCD 7 ntu lcd muaj qhov sib piv siab, nrog cov xim dub tob dua, ua rau pom pom tseeb ntawm cov cim dawb ntawm keeb kwm yav dhau los (VA feem ntau tsuas yog siv rau qhov tsis zoo lcd zaub).
The viewing angle is much better than TN lcd , approaching full viewing angle (>160 degree). Cov lus teb ceev yog me ntsis qeeb dua TN, tab sis nws txaus rau cov cwj pwm zoo tib yam thiab cov duab LCDs. Lub LCD zaub nyhuv ntawm cov cim dawb ntawm cov keeb kwm yav dhau dub yog qhov ntse thiab muaj qhov sib txawv. Nws feem ntau yog siv rau hauv cov lus qhia uas xav tau qhov sib txawv siab thiab pom dav, xws li cov cuab yeej siv tsheb, khoom siv kho mob, thiab kev tswj hwm kev lag luam.
Cov no yog cov laj thawj vim li cas peb nyiam VA cov khoom lag luam rau cov zaub tsis zoo lcd. Yog tias qhov muag pom ntawm cov khoom tsis siab thiab tus nqi tswj yog xav tau, TN 7 ntu lcd yog qhov kev xaiv zoo tshaj.
