Here’s how to remove a black spot from your phone’s screen that is spreading:
A black patch that spreads across a cell phone’s screen might happen in 4 different situations.
If there are stuck pixels, software can remove them.
You might need to replace the battery if the problem is pressure.
You might need to replace the screen if the problem is dead pixels.
The best course of action may be to replace the screen if it is broken.
Thus this post is for you if you want to learn everything there is to know about how to repair the expanding black spot on your smartphone screen.
Let’s get going!
Why Is There Spreading Black Spot on Your Phone Screen? (4 Reasons)
We all use our phones so frequently that it can be a major problem when something goes wrong.
A dark spot on your screen is one of the worst things you may see.
It indicates that there may be a problem with your phone that is difficult to fix.
The situation will get worse if that area begins to expand.
Let’s first examine what’s causing it in your situation before moving on to what you can do to fix it.
The black area that frequently shows on phone screens is not the only issue.
The truth is that screens are still made in distinctly different ways and are subject to particular issues today.
You can have dark patches that seem the same but are caused by very distinct problems on two phones that are otherwise similar.
We’ll go over the most frequent causes of the black spots so you can understand what is actually going on.
#1 Dead Pixels
The most frequent cause of a black spot (or spots) on your screen is probably dead pixels.
The tiny light sources known as pixels are what your screen uses to create images.
LEDs light almost all pixels today.
They are semiconductors that emit light and are available in a variety of sizes and forms.
The LEDs will provide either red, blue, or green light for your phone’s display.
The numerous light sources in the screen are then transformed into the image you see by other screen components.
As dying pixels don’t emit any light, the dead region will seem dark while images are being displayed on the screen.
There are several potential causes of dead pixels. They sometimes become exhausted.
They are more frequently harmed by impact or exposure to potentially harmful elements (like water).
Dead pixels typically don’t spread. When a pixel perishes, no other pixels are affected.
Hence, if you have spreading dead pixels, there is likely a second issue as well, which we will cover in more detail later.
#2 Stuck Pixels
Knowing a little bit more about how pixels operate, it might not come as a surprise to hear that they can become trapped.
The instructions sent to the pixels by other components to produce an image can be incorrect.
In that case, a pixel might stick. When it ought to be doing anything else, it will be the incorrect colour or off.
Liquid crystal screens are the most typical source of this (LCDs).
The pixels are actually instructed by the liquid crystals, and there may be communication issues that result in dark patches on the screen.
Once more, this often doesn’t spread over time, but it occasionally does.
The good news is that the answer will be detailed in a moment and that this is one of the simpler issues to fix.
Speaking of LCD displays, they are susceptible to outside pressure.
If you’ve ever touched an LCD screen with your fingertips, you’ve probably seen how the colours distorted and darkened.
Modern phones don’t have this issue because the touchscreen is thick and rigid enough to prevent much pressure from being applied to the LCD portion of the screen when it is touched.
Pressure issues typically originate from the opposing side.
Internal pressure might be produced if something swells or bends inside the phone.
A dark spot may result from such, and those dark patches are unquestionably prone to expanding.
#4 LCD Components
Outside of pressure, LCD parts are susceptible to harm and can develop black spots.
In particular, liquid crystals are housed in a large number of tubes in LCDs.
The liquid may seep out if these tubes break.
You’ll see a dark patch on the screen when this occurs.
However, even when the screen is off, the dark spot will still be visible.
The colouring on your phone screen is a result of leaking tubes, and it indicates that the screen has to be replaced.
Also, when the liquid spills and expands over time, there is a risk that the dark spot will spread throughout the screen.
How Do You Fix a Spreading Black Spot on Your Phone? (4 Ways)
We can look at solutions now that you are aware of what triggers the black spot on your phone and how it spreads.
The treatments must be appropriate for the various causes of the spot’s appearance.
In order to help you find the most dependable methods for restoring your phone screen to like-new condition, we’ll break it down by cause.
There are both DIY and expert treatments for each situation.
#1 Repairing Stuck Pixels
The simplest item on this list to fix is stuck pixels.
The digital control methods are the problem.
It implies that pixels can be unsticked using software.
You can hunt for a stuck pixel repair tool online or in your local app store.
It can run for a few seconds or for ten minutes.
In order to reset the mechanism, it cycles through the pixel controllers.
The pixels unstick after everything has been reset, and the screen functions normally once more.
#2 Relieving Pressure
You must open up the phone to locate the source of internal pressure when the Display pressure is the issue.
This entails taking down the screen.
There are DIY kits and instructions to follow, but if you feel uncomfortable, phone repair companies and professionals can handle it.
The pressure is probably the result of a bulging battery.
You’ve located the issue if taking out the battery stops the swelling.
You should be okay if you change the battery.
If the battery is working properly, you should check for any symptoms of bent or damaged parts that might be rubbing against the screen.
The pressure will decrease if those parts are straightened or replaced.
Sometimes the issue continues even after you release the pressure.
This indicates that additional repairs are required since the pressure was sufficient to harm the LCD tubes.
#3 Dead Pixels
Software can’t fix an issue when the pixels are dead.
The broken pixels will require replacement or repair.
That almost always indicates that the screen needs to be replaced.
Although it is technically possible to change a single pixel, doing so is not practical due to the minuscule size of pixels on contemporary screens.
It costs a lot of money and is difficult to find the equipment and knowledge required to do that.
Screen replacements, however, are reasonably priced.
You can either visit a repair shop with your phone or purchase a DIY screen replacement kit.
In either case, changing the screen will typically be less expensive than changing the entire phone.
Your phone may be an excellent candidate for an upgrade if it is sufficiently aged.
The issue is resolved since dead pixels are removed when the screen is replaced.
#4 Screen Damage
Spreading black patches are typically caused by cracked or broken Display tubes.
Significant screen damage is nearly always present in even less frequent problems.
You are once more considering a screen replacement for each of these circumstances.
Check all of your warranties to determine if they fully or partially cover the repair service to make your life easier.
Accidental damage plans are created specifically for situations like this.
Several screen protectors offer a screen warranty and will pay for some or all of the necessary repairs.
Examine all of your available warranties to see if you can make any savings.
Why Does the Black Spot Spread on Your Phone Screen?
As a result, some causes of dark spots are more prone to spread than others.
What is causing the darkness to flow across the screen in the first place?
There are a few main reasons behind that.
If the number of dead pixels on the screen is growing, this indicates that something is slowly but steadily damaging more and more pixels.
In essence, it indicates that your screen has a fracture that is growing larger.
Glass cracks have the same potential to propagate throughout the glass as a windscreen.
This may result in an increasing number of dead pixels on a phone.
If the pixels are merely frozen, it indicates that the control problem is escalating.
With LCD back pressure, the blackness is spread out over time as the pressure builds.
The battery is usually always swollen and getting worse when this happens (which is much less common with new lithium-ion batteries).
In the last scenario, when LCD tubes break, the liquid that is ejected may result in pressure building inside the screen structure.
This could lead to further tubes breaking, creating a domino effect where the dark spot on the screen keeps expanding.
