Have you noticed that your screen has a defective pixel? You can't help but stare at him for days, wondering if he has a solution, right?
In this tutorial, we will see together how to identify the problematic pixel, and even how resuscitate him.
What is a defective pixel?
Your computer screen is made up of millions of tiny, carefully programmed lights called pixels. All of these pixels form the screen image. A pixel is so small that you can hardly see it with the naked eye. The more a screen has, the sharper the image!
Within the pixels are sub-pixels that emit RGB colors (red, green and blue), which when lit together emit pure white light, while other colors are emitted by changing the levels of each of the three colors.
Un stuck pixel occurs whenever one of these subpixels stay stuck on one color – red, green or blue, and appears as a persistent, bright dot on your screen.
On the other hand in the case of a dead pixel, things are much more complicated. This one no longer displays any color. It remains off permanently causing a black spot to appear on the screen.
Causes of dead or stuck pixels
Dead or stuck pixels have plagued monitors since LCD screens first entered the scene.
The stuck pixels are stubborn little squares that keep one color all the time, but they are not always permanent.
They are caused by hardware problems, usually due to:
- Manufacturing defects such as assembly errors,
- A constantly on transistor, which could affect the pixel,
- Extreme temperature.
