Kuwala kwa LED kumatanthauza kugwiritsa ntchito LED (light-emitting diode) ngati gwero lakumbuyo la zowonetsera za LCD.Poyerekeza ndi chikhalidwe cha CCFL (cold cathode chubu) backlight source, LED ili ndi makhalidwe ogwiritsira ntchito mphamvu zochepa, mtengo wotsika wa calorific, kuwala kwakukulu ndi moyo wautali, zomwe zikuyembekezeka kuti zilowe m'malo mwa chikhalidwe cha backlight m'zaka zaposachedwa.

Kuwala kwa LED backlight ndipamwamba, ndipo kuwala kwa LED backlight sikudzachepa kwa nthawi yaitali.Komanso, thupi la LED backlight ndi lochepa kwambiri ndipo maonekedwe ake ndi okongola.
Kuwala kwa LED, mtundu wofewa, wokhala ndi mtundu wolimba wa skrini ungapangitse maso kukhala omasuka.
Ubwino wina ndikupulumutsa mphamvu ndi ma radiation otsika.
