Have you ever seen strange bright spots on your screen in dark areas? Now’s the time to take a closer look with a Backlight Bleed test. This simple yet effective check reveals if your display is up to par, ensuring you get the best viewing experience.
How To Test Your Monitor For Light Bleed
Total Time: 5 minutes
Prepare Your Monitor
First, ensure your room is as dark as possible. Clean the screen with microfiber cloth. Turn off any lights and close the curtains. The darker the environment, the better you’ll be able to spot any backlight bleeding.
Adjust the brightness
Set screen brightness to an optimal range and turn off any ambient lighting.
Start the test
Click Blacklight bleed test button bellow to start the test.
Inspect the Edges and Corners
Pay attention to any spots where the black appears lighter, usually in the corners or along the edges of the monitor. These are likely areas where backlight bleed is occurring.
Compare your findings
Scroll down to screen bleeding examples and compare if it’s something you’ve seen on your device.
Instructions:
- Press any key close the test anytime
- Inspect Edges and Corners for lighter black spots
- Use the Close button, to hide this instructions modal
Testing Phone for backlight bleeding
Detecting backlight bleed on a phone is slightly different than on a monitor. Since phones often don’t support full-screen mode in browsers as easily, we’ll use a different method involving a video.
- Move to a Dark room: Similar to testing a monitor, ensure you are in a dark environment. Turn off the lights and close curtains to remove external light.
- Play the Video in Full-Screen Mode: Open the black background video on your phone and switch it to full-screen mode. Make sure the video covers the entire screen with no distractions.
- Inspect the Screen: Carefully look at the edges and corners of your phone’s screen. Look for any areas where the black appears lighter or where light seems to seep through.
What is Backlight Bleed?
LCD bleed is an issue commonly found in screens, where light from the backlight escapes from the edges or corners of the display. It results in uneven lighting and can disrupt your viewing experience, especially in darker scenes.
Examples of Monitor Backlight Bleeding
Backlight bleed appear as bright spots or patches along the edges and corners of a screen, especially visible in darker scenes. When you’re watching a dark scene in a movie, you might see light leaking around the screen’s edges. Bellow are some examples of how monitor bleeding looks like.
Lcd Screen Bleed Or IPS Glow
Backlight bleed and IPS(In-Plane Switching) glow are often confused, but they are distinct issues:
- Backlight Bleed: This is a hardware issue where light leaks around the edges of a screen due to improper construction or design. It’s a structural flaw of the monitor or TV, resulting in uneven brightness across the display.
- IPS Glow: This occurs only in IPS panels and is due to the way light is dispersed by the screen. It’s seen as a glow around the corners when viewed from an angle, often appearing as a whitish or colored haze. IPS glow differs based on your viewing angle. To rule out backlight bleed, change your position in relation to the screen. If the glow lessens or shifts as you move, it’s likely IPS glow.
FAQ
Can OLED Screens Suffer From Backlight Bleed?
OLED technology operates differently from LCDs, as each pixel emits its own light. Therefore, OLED screens don’t typically experience backlight bleeding, but they may have other uniformity issues like burn-in or varying brightness levels.
Is Backlight Bleed Common in Laptop Screens?
Yes, laptop screen bleeding is a common phenomenon, particularly in LCD displays. Due to their compact design, inconsistencies in the backlighting can become more noticeable, especially around the screen’s edges and corners.
Are There Any Fixes for Backlight Bleed?
While a definitive backlight bleed fix doesn’t exist, reducing the monitor’s brightness can sometimes minimize the effect. For severe backlight bleed, the best course of action is to contact the manufacturer, especially if the device is still under warranty. Remember, gentle pressure on the screen’s bezel can sometimes reposition the light diffusers and lessen bleeding, but this should be done cautiously to avoid damage.
