Yuav ua li cas txheeb xyuas LED zaub screen, yuav ua li cas paub qhov txawv LCD thiab LED kom raug? 1. Lub kaum sab xis saib ntawm LED LCD npo yog qhov loj
Cov duab yuav tsis dim heev thaum saib los ntawm sab, thiab txawm yuav zoo ib yam li zaj duab xis tsis zoo, thaum lub dav LCD npo yuav hloov xim. 2. Cov lus teb ceev ceev heev
Thaum daim duab txav mus, yuav tsis muaj smear. Thaum lub vijtsam LCD dav dav ua cov duab dynamic, qhov ntau dua qhov smear yuav yog, qhov pom tseeb dua qhov smear yuav, thiab ntau qhov muag plooj.
3. siab dua brightness
LED LCD npo yog qhov ci heev, ci ntsa iab ntau dua li cov ntxaij vab tshaus LCD zoo tib yam, thiab nws tuaj yeem pom meej txawm nyob hauv lub hnub. 4. Screen nyias
Lub vijtsam LED dav dav yog thinner dua li lub vijtsam LCD dav dav. Qhov twg zoo dua, coj lossis lcc

Qhov twg yog qhov zoo dua, coj lossis lcd? Los ntawm qhov sib txawv ntawm lcd thiab coj, peb tuaj yeem xaus:
1. Ob lub LCD thiab LED muaj qhov zoo ntawm txhua lub nroog
LCD muaj qhov zoo ntawm qhov ci ntsa iab thiab haum rau xim; thaum LED muaj qhov zoo ntawm kev siv hluav taws xob tsawg, lub neej ntev, thiab qhov me me. 2. LCD thiab LED kuj muaj qhov tsis zoo
LCD tsav voltage kuj siab, lub thickness kuj loj, thiab lub zog noj kuj siab; LED dimming yog qhov nyuaj. 3. Led tau hloov coj (CCFL backlight)
CCFL backlit LCD yog ib yam khoom nrov dua ua ntej. Nyob rau theem no, feem ntau LCDs yog backlit los ntawm LEDs.
