What Are Black Spots on the Screen?

Black spots are just surface blemishes that occur for several reasons, and they can occur at any part of the screen. They can either be just small dots or appear as a dark shadow in the corner of a screen. These dots don’t indicate broken glass, and they won’t cause the display to die out on you.

Although these black dots are easy to fix, it’s essential to understand what’s causing them so that you can take the proper steps without damaging the LCD. Apart from overheating and manufacturing defects, black dots on your screen can be because of the following reasons.

Reason #1: Debris or Dirt

The black spots on your screen can be due to a superficial amount of dust, dirt, or smudges stuck to the surface (and not inside the screen). 

If left untreated, they can grow and eventually block more of the screen and make the rest of it seem dull. While these spots won’t damage the LCD, they are super annoying. Luckily, they’re quick to deal with.

Reason #2: Stuck or Dead Pixels

Pixels change colors to display the image on your screen. But in some cases, a pixel can get stuck on one color. If that color is black, you will see a black spot on your screen.

Black spots on your laptop and phone screen can also be because of dead pixels. An LCD comprises millions of pixels that come together to render the image to your screen. But to produce pictures, pixels must be illuminated by light. And when they don’t illuminate at all, they are known as dead pixels. As a result, you see a frustrating black spot on the screen.

Reason #3: Pressure

External pressure on the screen can also cause black spots. Pressure on the screen distorts colors and causes it to darken. The touchscreen used in phones today is so thick that touching it doesn’t apply too much pressure to it. But a swelling or bent part inside the phone can lead to internal pressure, resulting in a dark spot. 

Reason #4: Physical Damage

Black spots on your laptop and phone screen usually occur because of physical damage. If you accidentally drop or hit your device against something hard, you can expect to see irreversible black spots that will only spread with time.

Reason #5: Damaged LCD Components

Damaged LCD components can also result in dark spots. LCDs consist of tubes of liquid crystals. If these tubes break, the liquid starts to leak out, resulting in dark spots on the screen. You’ll be able to see them even with the screen turned off.

Fixing the Black Spot on the Screen

Black spots can appear for many reasons, and to fix them without causing further damage, you must determine the cause first. Different kinds of issues call for distinct methods, and there’s no one sure-fire way that can fix the spots. For instance, you can wipe the screen to get rid of dirt, but you can’t do the same to fix a dead pixel. 

If this sounds scary, don’t worry. Here are some easy ways to fix those annoying black spots.

Method #1: Clean the Screen

If the black spots are due to dirt and debris, you need to use a soft eraser or a slightly dampened microfiber cloth and clean the screen. Avoid putting pressure on the screen. Instead, use gentle strokes to avoid leftover marks and scratches.

Method #2: Pressure Clean

Here are some options to fix a dead or stuck pixel.

  • Clean the screen.
  • Spray some cleaning solution on your laptop’s or phone’s screen. Then, use a stylus and apply a little pressure on the dead pixel to move it from its place. Once it starts to move, drag it off the screen.
  • Mild pressure can also activate stuck pixels. Just make sure to avoid excessive force since it can lead to dead pixels or screen punctures.

Tip

You can put a soft microfiber cloth between the tip of the stylus and the screen while dragging off the dead pixel to reduce the chances of damaging the screen.

Method #3: Using Tools for Dead/Stuck Pixels

Another way to fix stuck or dead pixels on your laptop screen is with the help of JScreenFix. The website is 100% free and doesn’t require expensive software or equipment; you only need an internet connection and a laptop. Here’s what you need to do.

  1. Leave your computer off for two hours before starting. 
  2. Turn on your laptop and go to jscreenfix.com.
  3. At the bottom of the page, you will see a “Launch JScreenFix” button. Click on that. 
  4. The LCD will turn dark, and you will see a colored pixelated box. You can quickly move this box around the screen with your mouse. 
  5. Drag the box around to the problem area for 10 minutes to 1 hour. 

All the pixels in the problem area are forced to change colors quickly, which helps restore stuck or dead pixels.

Alternative Fix for Windows: PixelHealer

If JScreenFix doesn’t work for you, you can try using PixelHealer for your Windows laptop. This free application works pretty much in the same way and is a great way to get rid of stuck pixels.

Warning

Ensure you don’t stare at the screen while the app works since the flashing lights might trigger a seizure.

Alternative for Android: Dead Pixels Test & Fix (DPTF)

DPTF is a free app with an easy and self-explanatory interface. It also uses the same process and takes 10 minutes to 1 hour to fix the dead pixels. When running the app, make sure your phone is fully charged and connected to a power source. 

Method #4: Replace the LCD

If all else fails, the best thing you can do is get the LCD replaced, especially if your device is still under warranty. In most cases, pixel damage is considered a manufacturing defect, and the manufacturer will replace the LCD.

Summary

You now know what’s behind the black spots you’re seeing on your screen and how you can fix them. While these spots seem scary and worrisome, it’s easy to take care of them.
