See Dead Pixels on Your Phone Screen? Here’s How They Happened
Screens are the gateway to the digital space. But they’re nothing without the pixels. These may be puny things, but when put together, they can project your favorite shows, display pictures of friends on your Facebook wall, and present the news articles you read in the morning while sipping your coffee.
Pixels are vital for the user experience because they change color in response to images or content being displayed. These little guys are on all screens, from your computer to your phone.
But sometimes, pixels “die.” They usually look like a group or groups of black spots. These spots don’t illuminate and are annoying to look at. Sadly, they cannot usually be repaired (by yourself, at least).
To be better-equipped toto deal with this problem, you must know some stuff first. So, what causes dead pixels? How do we prevent this? Read on to find out.
What Is a Dead Pixel?
A dead pixel occurs when sub-pixels are permanently turned off, and sometimes, transistors malfunction, causing zero voltage to get to the pixel units. Each pixel contains RBG (red, blue, green) that changes to make up the picture. You’ll know when they stop working because they usually look like a cluster or black spots around your screen.
Are Dead Pixels Different from Stuck Pixels?
If there’s one thing both types have in common, it’s that they both affect user experience. But to know if your screen has dead or stuck pixels, you must see the difference between them.
Stuck pixels are what they are — stuck. They’ve lost their ability to change their colors, making them stuck to one color for a prolonged time. Whether big or small, they are noticeable and annoying. However, unlike dead pixels, they are less permanent. To stop stubborn pixels, run a changing screensaver to exercise the pixels. You can also use mobile apps to help with this. When not in use, be sure to turn off your display. But you can also wait for it to disappear. However, there’s no telling how long it’ll take.
Common Causes of Dead Pixels
Everybody’s automatic response is to do a quick online search on how-tos and DIYs to fix dead pixels. But in truth, there’s only so much you can do. So, while you still can, do your part to prevent dead pixels in your device. When it comes to dead pixels, you have two suspects. It only comes down to whether it was made that way or caused it yourself.
Manufacturing Defect
You might have been extra careful with your new phone, which you’ve never dropped. Yet, you find dead pixels sitting on your screen. This could be a manufacturing defect. These pixel defects are, more often than not, undetectable during assembly.
If this is the case for you, contact the manufacturer. But, first, have it replaced by a defect-free and functional one. Then, be properly compensated for the damage that you never caused in the first place.
Frequent Falling, Bumping and Knocking Over
Dropping your phone constantly can cause more than just cosmetic wear. Dropping is one of the most common reasons cell phone screen repairs are needed.
When you drop your phone, the fall damages the connection to one or more pixels on your screen, causing them to “die.” The transistor that relays the power fails to do so, which results in a black (and very annoying) spot that never lights up.
This is very avoidable, which is good news. But if you are way past that point and dealing with the consequences, focus on how to prevent further damage. For example, avoid placing your phone where it’s at risk of falling or unnecessary pressure.
Although there are DIY fixes you can do with the help of mobile apps, a sure and long-term solution is always to consult a professional. You can look up solutions all you want, but your safest bet is always to see a technician. The best and most reliable option to prevent it from reoccurring in the future is to have the LCD replaced by a professional.
If your phone is newly purchased, you should check with the manufacturer; they usually offer a warranty. They typically require a minimum number of dead pixels before they repair or replace the screen. This way, you can ensure that your phone gets the necessary repair.
