How to repair a dead pixel on your screen

The appearance of dead pixels is a problem that occurs quite frequently in all types of devices that include a screen. Monitors, televisions, smartphones, even SmartWatches are the devices most likely to suffer from this type of problem, due to all the works that are running throughout the day. In this article we explain what a dead pixel is, and some simple tricks to try to fix it without spending money.

First of all, we have to differentiate between what is a dead pixel and a stuck pixel. Today's screens are made up of a matrix of tiny dots, which are what we know as pixels. The pixels are those that are illuminated individually , and in different colors and intensities, to generate the final image that we see represented on the screen.

A stuck pixel is one of these points that make up the screen, which has been blocked in a certain color, for example, red. This means that said pixel is always illuminated in red, and never changes color. On the other hand, we have dead pixels , which are those that do not light up for some kind of reason.

dead vs stuck pixel

Stuck pixels are usually quite easier to repair than dead pixels, although this is not always the case.

Test with the pressure method

The easiest way to try to recover a dead or stuck pixel is to exert slight pressure on the area of ​​the screen where said pixel is at the moment the device is turned on. To do this you can help yourself with a soft cloth, for example microfiber or velvet.

With the device turned off, apply slight pressure with the cloth and a finger of your hand on the area where the stuck or dead pixel is located. Without stopping pressing, turn on the device and release the pressure that you were exerting on the screen, possibly you have managed to wake up the dead or stuck pixel.
