Cov qauv ntawm LED Backlight
Oct 02, 2022| LED backlight qauv feem ntau yog muab faib ua ob hom, ib pawg ntawm cov khoom siv hluav taws xob los yog ntau pawg ntawm cov khoom siv hluav taws xob / sib txuas. Txawm hais tias ib pawg ntawm cov khoom siv hluav taws xob siv hluav taws xob siv hluav taws xob tsis tu ncua, lub zog hluav taws xob yuav tsum tau txhawb nqa mus rau ib theem raws li tag nrho rau pem hauv ntej voltage ntawm cov khoom siv hluav taws xob ua ntej LEDs tuaj yeem tsav tau. Conversely, ntau pawg ntawm series / parallel LED cov khoom siv hluav taws xob xav tau ntau dua tam sim no los tsav, tab sis txo qhov xav tau ntawm qhov hluav taws xob siab. Boost converter yuav tsum tau sib txawv nyob ntawm tus nqi, complexity, thiab lub zog conversion efficiency (uas, rau cov neeg siv, sib npaug rau roj teeb lub neej ntawm cov nqi cycles). Thaum kawg, qhov kev daws teeb meem zoo tshaj plaws yuav raug txiav txim siab raws li cov yam ntxwv ntawm cov khoom, qhov loj me thiab kev ua tau zoo ntawm cov cuab yeej nws tus kheej.
