Did you discover a black spot on your LCD? & you want to know about How to Fix Black Spots on Laptop Screen? If it’s on the top, the bottom of the foot, it’ll probably stick out like a sour thumb.
If you fire up the LCD, the first thing you see will probably be the black spot. But you can take the requisite steps to avoid black spots on LCDs by knowing what causes them.
Superficial Dirt or Debris
Black spots are also only caused by superficial Dirt or debris. Debris & Dirt collect on the surface of LCDs over time.
This Dirt or debris can be manifested as one or more black spots if left unchecked. The black spots will not affect the output of an LCD or harm the inner circuit of the LCD.
Nevertheless, clean the LCD screen when superficial Dirt or debris creates a black spot is a good idea.
You can clean the screen of your LCD using a wet, not saturated, macro-free cloth. Rub the microfiber cloth softly on the panel when the LCD is switched off until the black spot is no longer apparent.
A stuck pixel is another common cause of black spots on LCDs. As its name suggests, any pixel in an LCD — or any other display system — that cannot change its color is a stuck pixel.
Pixels have been designed to change color following the image shown on the screen. If the color of a pixel does not shift, it is a pixel trapped.
A dead pixel can also trigger black spots on an LCD, which should not be confused with a stuck pixel. What exactly is the difference between a pixel trapped and a dead pixel?
When the LCD is switched on, a stuck pixel will be lit; it will not change color. On the other side, a dead pixel would not be discarded.
In other words, all three of the dead pixels – red, green, and blue – are switched off forever. And since they’re not lit, dead pixels on the projector appear like black spots.
