Quick Summary

Backlight refers to illumination from behind or the source of that illumination. In electronics, this is commonly associated with Liquid Crystal Displays (LCDs). LCDs use liquid crystals, materials with properties between liquids and solids, to create images. An electric voltage applied to the liquid crystal layer alters its optical properties, controlling how light passes through. Many electronic devices, from mobile phones to computer monitors and televisions, utilize LCD technology, often with a backlight to enhance brightness.12
