Dab tsi yog qhov pom kev ntawm LED backlight? Hauv kev npaj ntawm qhov kev teeb tsa, qhov kev xaiv ntawm qhov pom kev siv yog qhov tseem ceeb heev. Lub teeb pom kev zoo siv los txiav txim siab tsis pub muaj qhov teebmeem xws li kev siv fais fab, ci ntsa iab, xim, thiab lwm yam. Cov nram qab no qhia tau hais tias lub teeb ci uas siv tau rau LCD backlights thiab lawv cov nta:
Lub teeb ci teeb lub teeb Lub teeb hom xim Xaiv lub zog (W) (Lub neej) Lub neej (h) (teev) Nta
Taw tes teeb ci Qhov teeb (teeb) 2800K los yog li 1.0 los yog ntau dua 2,000 Yooj yim, me me, tsis tshua muaj nqi Loj loj, kub thiab loj
LED (Lub teeb Emitting Diode) xiav ~ liab 430 ~ 700nm 0.038 los yog ntau dua 100,000 Lub neej ntev, tsawg cua sov, tsis tshua pom kev
Teeb duab qhov teeb meem CCFL (txias cathode fluorescent tube) Liab, xim ntsuab, xiav thiab lawv cov xim sib xyaw xim 1.0 ~ 10.0 25,000 High brightness thiab ntev lub neej Qhov hluav taws xob inverter tsav yog siab
HCFL (kub cathode fluorescent tube) 4.0 ~ 220 5 ~ 7,000
Qhov teeb ci ntsa iab VFD (lub teeb plhaub fais fab) 200mW / cm2 los yog tsawg dua 5,000 High brightness thiab uniformity Dual power supply
EL (electroluminescent sheet) 20mW / cm2 los yog luv dua 5,000 Nyias, khaub ncaws, lub neej luv luv, tsis tshua muaj siab
OELD (Organic Electroluminescent Sheet) 1,000 los sis ntau tshaj Nyias, hnav, siab ua kom pom, luv luv
FED (puav lawm cov pa emission) 10,000 lossis ntau tshaj Cov Ntsuas Hauv txoj kev loj hlob
