Backlight bleed is a defect found in LCD and LED displays. It is a defect caused by the leaking of light from the backlight panel on the screen. The Backlight bleed can diminish your visual experience.

The LCDs are designed in a multi-layered fashion because they do not have any light of their own. So, a backlight panel is integrated which provides the LCD with the light it needs to create visuals for you on the screen.

The empty space, cracks, and other defects in the construction of the display can allow the backlight to leak from the surface and appear on the edges or corners of your screen. It is called backlight bleeding.
