Ultra nyias
Lub thickness ntawm tsoos LCD TVs feem ntau yog hais txog 10cm. LED backlighting yog ntau dua nyob rau hauv phau computers. Thaum siv hauv TV, lub thickness ntawm lub cev tau dhau los ua nyias.
Kev txuag hluav taws xob
CCLF txias cathode fluorescent teeb, lub backlight siv nyob rau hauv ib txwm LCD TVs, muaj mercury uas muaj teeb meem rau tib neeg lub cev. Txawm hais tias cov tuam txhab lag luam tab tom sim txo cov ntsiab lus mercury hauv cov raj fluorescent, cov raj tsis muaj mercury tsis muaj fluorescent yuav ua rau muaj teeb meem tshiab. LED backlight muaj kiag li tsis muaj mercury thiab yog nyob rau hauv txoj kab nrog ntsuab thiab ib puag ncig tus phooj ywg zam. LED backlights kuj muaj zog heev. Lub zog tsav sab hauv ntawm LED yog qis dua CCFL, thiab kev siv hluav taws xob thiab kev nyab xeeb zoo dua li CCFL.
Lub neej ntev
Cov kev pabcuam lub neej (ib nrab-ci) ntawm CCFLs sib txawv ntawm 8, 000 txog 100,000 teev. Kev pabcuam lub neej ntawm CCFL backlights nrog kev tsim kho kom zoo dua qub yuav ua rau qis dua. LED backlight tuaj yeem ncav cuag li ob npaug ntawm CCFL. Yog li ntawd, lub neej kev pab cuam ntawm LED backlights feem ntau yog ntev dua li ntawm CCFLs.
Dav xim gamut
Qhov tseeb, nws yog qhov zoo ntawm daim duab. Raws li cov xim sib txawv, LED tuaj yeem muab faib ua dawb LED backlight thiab RGB-LED backlight. Lub ntsiab kom zoo dua ntawm cov tshuab LED dawb yog qis zog noj, thaum qhov zoo ntawm RGB-LED backlight yog cov xim zoo heev. RGB-LED backlight siv cov khoom siv LED uas tuaj yeem tso tawm cov teeb pom kev zoo xim liab, ntsuab, thiab xiav kom ua tiav cov xim dav dav uas tsis tuaj yeem ua tiav los ntawm cov khoom siv hluav taws xob CCFL. Tam sim no lub ntsiab RGB-LED backlight tuaj yeem ncav cuag 105% ntawm NTSC xim gamut, thiab LED cov khoom siv nrog kev ua tau zoo dua tuaj yeem ua tiav ntau dua 120% ntawm NTSC xim gamut.
Rau LCD TVs, nws cov qauv duab tshwj xeeb uas siv cov kev hloov pauv ntawm cov kua siv lead ua kua molecules los tswj lub teeb sab nraud txiav txim siab tias lub LCD vaj huam sib luag yog tus yuam sij rau cov nyhuv. Yog li ntawd, thaum yuav lub TV, qhov taw qhia tseem ceeb yog seb cov khoom puas siv lub vaj huam sib luag zoo. LED tsis ua lub luag haujlwm kiag li!
