What Is Backlight Bleed?
Backlight bleed is a common effect in LCD displays.
LCD panels work by projecting light from behind the panel, which illuminates the pixels. The pixels filter the light colours that aren’t necessary for displaying a particular image.
Sometimes, some of the light from the rear of the panel escapes from the edges of the screen which causes some areas to be brighter than others. This can be more noticeable when the TV or monitor is displaying a dark picture or a static image.
A small degree of backlight bleed is completely normal and does not indicate a fault with the display.
How Can I Reduce The Effect Of Backlight Bleed On My LCD Screen?
While backlight bleed cannot be completely removed in most cases, the effect can be improved by lowering the brightness settings on your TV or monitor.
Backlight bleed can develop due to the presence of foreign objects such as dust. Unplug the TV or monitor, then use a dry microfiber cloth to clear this away from the affected area. Ensure that you don’t apply too much pressure to the screen while wiping it, and never use liquids such as water to clean your LCD screen.
What If The Backlight Bleed Is Abnormally High?
While a small degree of backlight bleed is normal, widespread areas of extreme brightness may indicate an issue with your LCD screen. The following photos demonstrate severe backlight bleed issues:
