Dab tsi yog cov teeb pom kev zoo ntawm LED backlight? Hauv kev npaj lub teeb pom kev zoo, kev xaiv cov teeb pom kev zoo siv yog qhov tseem ceeb heev. Lub teeb ci siv los txiav txim siab lub zog noj, ci ntsa iab, xim thiab lwm yam photoelectric tsis muaj teeb meem ntawm lub teeb, nrog rau nws cov kev ua haujlwm thiab kev ua haujlwm ntawm lub neej. Cov lus hauv qab no yog qhov sib piv luv luv ntawm cov teeb pom kev zoo thiab lawv cov yam ntxwv uas tuaj yeem siv rau LCD backlights:
Lub teeb pom kev zoo Lub teeb ci hom xim Lub zog noj (W) (Watts) Lub Neej (h) (teev) Nta
Point light source Teeb (bulb) txog 2800K 1.0 lossis ntau dua 2,000 Yooj yim, me me, tsis tshua muaj nqi Loj loj, tsim hluav taws xob hnyav
LED (Lub Teeb Emitting Diode) Xiav ~ Liab 430 ~ 700nm 0.038 lossis ntau dua 100,000 Lub neej ntev, tsis tshua muaj cua sov, qis qis dua
Linear light source CCFL (txias cathode fluorescent tube) Liab, ntsuab, xiav thiab lawv cov xim sib xyaw 1.
HCFL (Kub Cathode Fluorescent Tube) 4.0~220 5~7,000 Kev kub ntxhov
Planar light source VFD (flat fluorescent teeb) 200mW/cm2 los yog tsawg dua 5,000 High brightness thiab zoo uniformity Dual power supply drive
EL (Electroluminescence Sheet) 20mW/cm2 los yog tsawg dua 5, 000 Nyias, zoo uniformity, luv lub neej, tsis tshua muaj brightness
OELD (Organic Electroluminescence Sheet) 1, 000 lossis ntau dua Nyias, zoo sib xws, siab ci, lub neej luv
FED (Flat Field Emission) Saum toj no 10,000 Siab ci ntsa iab Nyob rau hauv txoj kev loj hlob
