Light leakage or light bleed refers to light leak from the backlight to the edges or corners of lcd screens Light leakage (also known as backlight bleeding) is an aspect of lcd panel technology in which light can appear brighter along the edges or corners of an lcd display It is common on all lcds, not only wacom displays

It is due to the nature of lcd panel structure, and is generally unavoidable based on current production technologies
It's usually more visible on darker environments but barely visible in regular lighting conditions
Backlight bleed is characterized as light leaking around the edges or corners of an lcd It is fixable in some cases How to fix backlight bleed on monitors and tvs troubleshooting light leaking from the edges of your display How to identify lcd screen light leakage please check for light leakage in a brightly lit environment, ensuring the ambient light meets industry standards of at least 150 lux per unit area (e.g., typical office lighting).
