Dead pixel on iPhone 7 plus. Detecting and eliminating dots on the iPhone screen
Sometimes you may get unlucky and after a couple of months or more, ("dead") dead pixels may appear on your display.
An excursion into history. What is a dead pixel?
The image on the monitor with an LCD display is the same as with cathode ray tube, consists of points, in a narrow circle called pixels. They are the ones that form the various pictures that we see through changing colors. The pixel also has its own permanent hierarchy - three subpixels, black, red and green. The final color is achieved by changing the position of individual subpixels and directing the light beam at it different power. IN modern monitors, using the so-called active matrix, each pixel is controlled by its own thin film transistor (TFT, Thin Film Transistor), the failure of which forms on the screen black inactive dot – dead pixel . It does not change its color when changing the image precisely because technical malfunction control transistor. Such dead pixels can only be restored by replacing the corresponding transistor, which can only be done in special laboratory conditions, which is clearly not available to ordinary users.
If you are so “lucky” and you have just such a black dot on the display of an iPhone, touchscreen or even a monitor, then good luck... But if you have a dead pixel glowing, let’s say brightly green, as was the case in my case with the iPhone 3GS, then you can “revive” it!
Stuck dead pixels
There is another type of dead pixels - stuck . A sign of their appearance will be a light dot on a dark background. This happens when an individual subpixel gets stuck in one position. Respectively it does not respond to changes in the image on the display, but glows a certain light color. Such defects, unlike blackheads, can be restored at home through some software and physical manipulations.
Unfortunately, I didn’t take a photo of this pixel when it wasn’t working, but there are many “lucky” people on the Internet with similar symptoms.
Treating a dead (stuck) pixel
The essence of the method is simple, suitable for both iPhone display and LCD monitor. For monitor owners, go to the website http://www.jscreenfix.com and click on Launch the JScreenFix. A window appears with small colored dots that quickly change color.
For iPhone or touch owners, download a short (518kb) video jscreenfix_qvga_ipod.m4v. Run it for 10-15 minutes and your dead pixel will miraculously come back to life.
The trick to this method is that it performs high-speed color changes on individual pixels, allowing you to programmatically realign a stuck pixel.
There are times when iPhone, iPad or iPod users encounter one of the problems with their device screens - dead pixels. It's worth remembering that there are differences between dead, hot and stuck pixels. There is also such a thing in the world as a group of defective pixels - this is the number of defective pixels in a square, the size of which is 5x5 pixels.
Dead pixels are pixels that do not glow in active mode. On a white background they resemble a black dot. And hot pixels are those that, when actively standing, look like white dots on a black background. Stuck pixels may glow different colors: red, yellow, blue, green. The reason for this is the on or off state of the subpixels.
Most users might think that if such a problem arose, it could be solved by sending the device for repair or exchanging the device under warranty. However, panel manufacturing technology is very complex, making it nearly impossible to produce large production runs of LCD panels without dead pixels. Even if only “clean” panels were used in production, the price of TVs would be high.
To solve this problem on Apple devices, there is a program that solves it - Bad Pixel Fixer. This program can be free and easily installed from Cydia.
You need to do the following:
- First, you need to make sure you have an Internet connection and then go to Cydia.
- Type - Bad Pixel Fixer in the search.
- Then make sure that this program from the repository is BigBoss.
- Next you need to install Bad Pixel Fixer.
- After the installation of the program is completed, you will see the “Bad Pixel” icon of this program in the menu of your device.
- Then run the program.
- Here you need to select a background - black or white. You can identify a dead pixel in the background and find out which group it belongs to.
- Point the square at the place where you found the dead pixel.
- Set the maximum interval, and select the color of the square in accordance with the color dead pixel, then all the colors of this square and click Start.
The work will take about 40 minutes. First you need to set the square with the dead pixel color. If this doesn't work for you, set all the colors of the square. Good luck!

We calculate dead pixels.
Do you have a dead or stuck pixel on your iPhone screen? Or are you afraid that such pixels may be on a display, for example, purchased from iPhone hands? This instruction tells you how to detect dead pixels on iPhone screen, and then get rid of them.
How to detect dead pixels on iPhone screen
Step 1. Download free application Dead Pixel 2 from the App Store.
Step 2. Launch the application and click on the button Mono Color. The entire screen of your iPhone will begin to display one solid color. Take a close look at the display to check for dead pixels.
Step 3: Click the button Next to change the color on the iPhone screen. Take a close look at your smartphone screen again.
Step 4: Keep Clicking Next to change colors and take a closer look at your iPhone screen. The application allows you to examine the display for dead pixels in eight different colors. It is recommended to check each of them.
It is not difficult to notice a dead pixel. A broken (or “dead”) pixel does not light up at all. It is easiest to detect it on a white background, since a dead pixel will be black.
Not everyone knows, but there is a concept of “stuck” pixels. Such pixels are frozen in the red, blue, or green state indicated by the subpixel. These pixels work but cannot change until required colors. Dead and stuck pixels are fixed in different ways.
How to fix a stuck pixel
Step 1: From iPhone, go to the website http://www.jscreenfix.com/ and press Launch JscreenFix.
Step 2: Move the square area to the stuck pixel.
Step 3. Leave the iPhone in this state for 10 minutes. The smartphone screen must be active all this time. Make sure your iPhone is not locked.
After 10 minutes of waiting, the “stuck” pixel will work again. If this does not happen, then the operation described above must be repeated.
How to fix a dead pixel
With “dead” pixels everything is much more complicated, that’s why they are called “dead”. Most often, the only way to get rid of them is to service centers. However, there are two ways to bring the pixel back to life at home.
The first method is to lightly press the iPhone screen in the place where the dead pixel is located. To do this, take a piece of lint-free fabric (or clothing) and press your finger through it onto the area of the “dead” pixel. Important! The display should be pressed lightly to avoid damaging it.
The second method involves heating the area of the dead pixel. To do this, boil water, soak a piece of lint-free cloth in it generously and place the cloth in a plastic bag, creating a kind of heating pad. Place a heating pad on the iPhone screen in the area of the problematic pixel and wait about a minute. An improvised heating pad can be rotated around a “dead” pixel to achieve a greater effect.
