backlight bleed

Light leaking unevenly from an LCD backlight around the edges, visible as bright patches on dark screens.

Full Definition & Technical Explanation

Backlight bleed is uneven light leakage from an LCD's backlight, most visible along the edges of a dark or black screen as glowing patches. It is a manufacturing and assembly tolerance issue rather than a pixel fault, and it varies between individual units.

It is distinct from blooming, which comes from local dimming.
