Understanding Screen Bleeding

What is Screen Bleeding?

Screen bleeding occurs when light from the backlight of an LCD or LED screen leaks through the edges of the display panel. This leakage is usually due to imperfections in the manufacturing process, where the layers of the screen are not perfectly aligned or sealed. The result is an uneven distribution of light, which can be distracting and affect the overall viewing experience.

Causes of Screen Bleeding in Android Devices

Several factors can contribute to screen bleeding in Android devices:

• Manufacturing Defects: Imperfect sealing or alignment of the screen layers during manufacturing.
• Pressure on the Screen: External pressure, such as from a tight case or accidental bending, can exacerbate the issue.
• Temperature Fluctuations: Extreme temperature changes can cause the screen materials to expand or contract, leading to gaps and light leakage.
• Age of the Device: Over time, the adhesive holding the screen layers together can degrade, increasing the likelihood of screen bleeding.

Identifying Screen Bleeding vs. Other Display Issues

It’s important to differentiate screen bleeding from other common display problems:

• Dead Pixels: Small, permanently black or brightly colored spots on the screen.
• Image Retention (Burn-in): Faint ghost images that remain visible even after the original image has disappeared.
• Color Distortion: Inaccurate or inconsistent color reproduction across the screen.

Screen bleeding is characterized by irregular patches of light, usually along the edges, while the other issues have distinct visual signatures.

Performing a Screen Bleeding Test on Your Android Device

Preparing for the Test

Before conducting the test, ensure the following:

• Dim the Lights: Perform the test in a dark room to make the screen bleeding more visible.
