Yog li ntawd, LED backlights yuav inevitably ua raws li lub tswv yim tsim thiab txhim kho qhov zoo ntawm tus tsim. Cia lub teeb ci LED no tiag tiag nthuav tawm lub zog qis dua, thiab tseem qhia tau tias muaj txiaj ntsig zoo dua hauv cov ntawv thov tom ntej, txhawm rau txhim kho cov duab zoo ntawm tus qauv tsim nrog cov ncauj lus kom ntxaws ntxiv.
2. Tsom ntsoov rau siab saturation thiab sib piv
Raws li peb txhua tus paub, thaum lub sijhawm ua haujlwm tiag tiag ntawm cov ntxaij vab tshaus tam sim no thiab lwm yam khoom siv, qhov zoo ntawm LED backlight ncaj qha cuam tshuam rau cov xim saturation thiab qhov sib txawv ntawm lub vijtsam, thiab cov tub lag luam uas muaj cov kev pabcuam zoo LED backlight qhia tias thaum tsim. xws li cov khoom Ib tug zoo muaj nuj nqi thiab siab dua ncej hloov. Nyob rau hauv lub neej yav tom ntej txoj kev loj hlob, lub ilv daim duab zoo nkauj thiab cov duab tshwj xeeb tso saib nyhuv tau dhau los ua qhov tseem ceeb ntawm cov neeg siv khoom' saib xyuas. Yog li ntawd, LED backlight yuav inevitably txhim kho daim duab zoo nrog cov duab zoo thiab siab sib txawv nyob rau hauv lub neej yav tom ntej tsim.
Txhua yam nyob rau hauv tag nrho, qhov tsim ntawm LED backlight ncaj qha cuam tshuam rau kev siv cov khoom siv LCD hauv kuv lub teb chaws. Cov neeg siv khoom uas nkag siab txog tus nqi tam sim no ntawm LED backlight cov kev pabcuam thiab cov khoom lag luam sib xws tuaj yeem pom tau tias kev txhim kho ntawm lawv cov khoom siv hluav taws xob yuav ua rau muaj kev xav tau zoo. Kev vam meej tsis tu ncua thiab kev sublimation. Thiab peb cov neeg siv khoom tsuas tuaj yeem ua raws li cov qauv ntawm lub sijhawm thiab xaiv cov khoom siv zoo thiab txhim khu kev qha LED backlight tsuas yog tias lawv nkag siab txog cov xwm txheej tshwj xeeb thiab daim ntawv thov ib puag ncig ntawm LED backlights tam sim no.
