Common Display Issues on OLED Screens: Green Lines and Screen Burn-In

[Sathir]

Many users have reported encountering green lines or other display issues on OLED screens, especially on certain models. Let’s break down what could be happening, what screen burn-in is, and how such issues occur on OLED displays.

Note : Avoid Static Images
Use features like Always-On Display carefully. Lower brightness settings and enable screen savers when the screen is idle.

Why Is This Happening?

1. Hardware Defects:
   Green lines or other anomalies may arise from physical damage to the display's thin-film transistor (TFT) layer or the electrical pathways connecting the pixels. This often happens over time or after minor drops or pressure on the screen.

2. Software Glitches:
   Sometimes, software bugs related to graphics rendering can cause display irregularities. These can be tested and, in some cases, resolved through software adjustments.

3. Aging OLED Panels:
   OLED panels rely on organic compounds that naturally degrade over time. Prolonged exposure to static images can cause certain pixels to wear out faster, leading to artifacts like lines.

What is Screen Burn-In?

Screen burn-in refers to the permanent discoloration of areas on an OLED screen caused by uneven pixel wear. For example:

1. Frequently displayed static elements (e.g., navigation bars or app icons) may leave a "ghost" image even when they're not displayed.
2. This occurs because those pixels have been used more than others, creating uneven brightness or color reproduction.

How Do Green Lines Appear in OLED Displays?

Green lines often result from:

1. Pixel Driver Issues: Each pixel in an OLED screen has its driver. If one driver malfunctions, it can cause entire rows or columns of pixels to appear green.
2. Electrical Disruption: A damaged circuit connection in the OLED matrix may activate pixels in a straight line incorrectly.
3. Pressure or Drop Damage: Physical stress on the display can disrupt the alignment of subpixels, leading to visible lines.

Is There a Way to Fix It?

Here are some possible solutions, depending on whether the issue is software or hardware-related:

1. Check for Software Updates:

   • Ensure your device’s software is up to date.
   • Updates often include bug fixes for display rendering issues.

2. Disable Hardware Overlays:

   • Go to Settings > Developer Options.
   • Enable Disable HW Overlays to force GPU rendering.

3. Run a Pixel Refresh Cycle:

   • Some devices come with built-in tools to refresh or recalibrate the pixels.
   • Check Settings > Display > Screen Care or Screen Refresh (if available).

4. Third-Party Apps for Burn-In Repair:

   • Try apps like OLED Saver or Burn-In Fixer, which cycle colors across the screen to recalibrate stuck pixels or reduce visible burn-in.

5. Professional Diagnosis:

   • If the green line persists, visit a certified Samsung service center to diagnose whether it's a hardware issue. If your device is under warranty or TRCSL-approved, repairs may be free or subsidized.

In my years of being on this app, not one single person has ever complained of burn ins. I think now the software and hardware optimization is so good that burn ins don't occur in the frequency it used to.

Green lines are still an issue, and so far, we don't have easy fixes.

In some cases, I’ve noticed within my circle that a pinkish hue on the screen can actually be a red color burn-in, which is more noticeable on AMOLED displays. Just thought to cover this as well in my post.
