Backlight lifespan ntawm kev lag luam qhia siv txias cathode fluorescence

Lub teeb yog lub teeb pom kev zoo tshaj plaws hauv LCDs. Nyob rau hauv daim ntawv thov kev lag luam, lub neej ntev ntawm CCF backlight feem ntau yog tsawg kawg yog 50000 teev, lossis lub sijhawm thaum lub teeb ci poob los ntawm ib nrab piv rau cov tshiab. Hauv ntau cov neeg siv khoom siv, nws tsuas yog siv sijhawm 10000 teev rau qhov ci ntawm lub teeb nraub qaum kom poob mus rau ib nrab ntawm nws qhov pib ci ntsa iab.
Vim qhov tseeb tias cov neeg siv khoom siv tsis tas yuav tsum tau ua haujlwm txuas ntxiv ntawm tus saib, lub neej ntev ntawm 10000 teev rau CCF backlight yog txaus, tab sis qhov no tsis yog nyob rau hauv feem ntau kev lag luam thiab kev siv kho mob. Lub lifespan ntawm backlight yog tsawg heev piv rau cov LCD. Tib neeg siv zog ua ob npaug ntawm lub neej ntawm lub teeb, tab sis nyob rau hauv feem ntau cov ntawv thov kev lag luam, qhov tsawg kawg nkaus lifespan ntawm 50000 teev yog suav tias yog tus qauv lifespan rau CCF backlights.
