What Is A Dead Pixel and How Does It Occur?
A dead pixel is when the RGB (Red, green and blue) picture element of the screen is used to display a picture on the screen that is permanently shut down or malfunctioned. This causes it to turn into a black spot known as a dead pixel.
To spot a dead pixel on your screen just look for a black spot on your screen or lookout for a dead pixel test software. Dead pixels will always show up on the same spot no matter what because a particular spot is dead so it cannot change its position.
This phenomenon occurs when the transistor fails to supply power to the display causing it to stop illuminating light. This results in turning black on the display. It is mostly a manufacturing defect but can be caused due to physical damage later in the use.
Bumping the display or knocking the display may damage the connection of the pixel which may result in the occurrence of a dead pixel.
What Is A Stuck Pixel?
Stuck pixels are usually red, green, blue, or yellow in color. These pixels are fixed and don’t change their color. They always receive power and keeps illuminating which results in a colored pixel that shows up in the same spot on the picture. Stuck pixels are very common and unlike dead pixels, they can disappear over time.
To spot a stuck pixel open up your camera app and set on live view, after that look for a pixel that never moves and has the same color. If you spot this, it likely that you have a stuck pixel on your screen. You can also use software to detect if there are any stuck pixels on your monitor. There are software programs that let you change colors rapidly cycling through varieties of colors on the affected part of your monitor.
This program constantly forces the stuck pixel to change colors. This is also a method that you can apply in order to fix stuck pixels.
