Have you noticed a dark area on your LCD? & you’re curious in How to Fix Black Spots on Laptop Screen? If it is located on the top or bottom of the foot, it will most likely stick out like a sore thumb.
When you power on the LCD, the first thing you’re likely to see is the black spot. However, by understanding what causes black spots on LCDs, you can take the necessary precautions to avoid them.
Dirt or Debris on the Surface
Additionally, black patches are caused solely by surface dirt or debris. Over time, debris and dirt accumulate on the surface of LCDs.
If left untreated, this dirt or debris can emerge as one or more black spots. The black spots will have no effect on the LCD’s output or on the LCD’s internal circuitry.
Nonetheless, cleaning the LCD screen is a smart idea when superficial dirt or debris causes a black spot.
You can clean your LCD panel using a damp, but not saturated, macro-free cloth. When the LCD is switched off, gently rub the microfiber cloth across the panel until the black spot is no longer visible.
Pixel That Is Stuck
Another typical source of black spots on LCDs is a trapped pixel. As the name implies, a stuck pixel is any pixel in an LCD — or any other display device — that cannot change its colour.
Pixels have been programmed to change colour in response to the image displayed on the screen. If the colour of a pixel does not change, it is referred to as a trapped pixel.
Pixel that is no longer alive
A dead pixel can also result in black areas on an LCD, which is not the same as a stuck pixel. What is the distinction between a stuck pixel and a dead pixel?
When the LCD is turned on, a stuck pixel is illuminated; its colour does not change. On the other hand, a dead pixel would remain.
In other words, the three dead pixels — red, green, and blue – are permanently turned off. Furthermore, because they are not illuminated, dead pixels on the projector look as black dots.
How to Identify a Dark Spot on a Laptop Display

- The laptop will restart once the test is complete.
How to Fix Black Spots on Laptop Screen?
Often, pixels on your laptop screen become caught, resulting in the appearance of a red, blue, green, white, or dark area. If you have an LCD mirror, you can remove the shattered pixel by gently rubbing it.
If not, get the assistance of a software programme to assist you in eradicating it. Jscreen Fix, Dead Pixel Buddy, and Pixel Fixer are all software applications that are intended to locate and repair damaged pixels on your laptop screen.
Clean your LCD screen with a soft, lint-free cloth. Utilize a stylus pen with a circular tip and place a little cloth directly over the pixel. Gently rub the pixel with the stylus pen until it vanishes.
Avoid applying excessive pressure to your LCD panel, since this may cause it to puncture. Proceed to the next level if the broken pixel cannot be removed.
On your computer, download and install a pixel fixer programme from the Internet. Launch the application and allow it to operate on your device.
If you prefer a web-based online service such as “JScreen Fix,” simply visit the website (jscreenfix.com) and click on the ‘Launch’ button.
Ascertain that your PC is running the latest Java version. The application is available for download at java.com. The service rapidly activates and deactivates all pixels on your laptop screen, cycling the colour around 60 times per second.
After the dialogue box “JScreen Fix” displays, click the “Locate” button. Your monitor’s display screen will be black. To locate the pixel on the panel, you must rotate the window.
To find and repair damaged pixels on your LCD screen, click the “Fix” button and allow a Web-based diagnostic service to conduct the test.
Tips: If you are unable to remove a broken pixel from your LCD panel, the pixel may be faulty or dead. For several hours, rerun the pixel fixer app to check whether this resolves your dead pixel issue.
If four or more pixels on your Laptop Display are missing and cannot be recovered, contact the manufacturer of your LCD. If you already have a warranty and meet the repair criteria, the LCD manufacturer may replace the laptop screen in specific cases.
Take note that LCD manufacturers will sell a certain percentage of laptop displays that have damaged pixels. Thus, selecting an LCD display with strong user feedback is a wise choice.
