Our laptop and PC screens comprise of millions of miniature lights, which create astounding image and videos. These building blocks are called pixels. These pixels have sub pixels with RBG colors, which together emit a white light. However, if any pixel gets out of function, its sub pixels go off accordingly. Then the pixel appears completely black and these are called dead pixels. There are a plethora of reasons, why a pixel may become dead. If a transistor is damaged, then no power is supplied, leaving the pixel black. Sometimes, a pixel might get stuck with a particular color pixel. That is all the colors are changing, but one or two pixels are stuck with the same color. This is called stuck pixel. Stuck pixel, unlike dead pixel, can be fixed and brought back to action.
