Backlight

Backlight refers to the light source behind a display screen, such as a computer monitor, smartphone, or TV, that makes the images visible. Without backlight, screens would appear dark or unreadable because they rely on this light to illuminate the pixels that produce images. In devices with LCD screens, the backlight shines through the liquid crystal layer and color filters to create the visible picture. The quality, brightness, and uniformity of the backlight directly impact the clarity, color accuracy, and overall viewing experience of the display.
