About Backlight Bleed Test
Check LCD and IPS screens for backlight bleed, IPS glow and clouding with a true black full screen test.
Backlight bleed is light that leaks around the edges of an LCD panel, showing up as bright patches in the corners when the screen should be black. It is common on IPS phones, laptops, monitors and budget TVs, and it is much easier to see in a dark room. A backlight bleed test shows a pure black screen so every leak becomes visible.
How To Run A Backlight Bleed Test
- Turn the room lights off or close the curtains.
- Set brightness to about 50 to 100 percent.
- Open the black test color in full screen and look straight at the panel.
- Note any light patches along the edges and corners.
Backlight Bleed Or IPS Glow
Bleed stays in the same place no matter where you look from. IPS glow changes or fades when you move your head, and it is normal for IPS panels. Clouding looks like uneven grey blotches in the middle of the screen. OLED screens have no backlight, so they cannot bleed at all, but they can suffer from screen burn-in instead.
Which App The Install Button Opens
The button opens Screen Check: Dead Pixels Test by OnTheBean on Google Play. Its fullscreen color mode, including pure black, is ideal for spotting bleed, glow and clouding, and it also flags dead pixels and burn-in at the same time.
