Stuck (Fixable) vs. Dead Pixels ( Not Fixable)

A stuck pixel is a bright dot of colour that fails to update when neighbouring pixels change. Stuck pixels are most noticeable when the rest of the screen is black. Stuck pixels are different from dead pixels. A stuck pixel is a single color – red, green, or blue – all of the time. A dead pixel is black instead. While it’s often possible to “unstick” a stuck pixel, it’s much less likely that a dead pixel will be fixed. While a dead pixel may simply be stuck at black, it’s possible that the pixel isn’t receiving power at all. A faulty pixel displaying the color white all of the time is known as a “hot pixel.”

Pixel combines two words, ‘ pix’ (picture) and ‘el’ (elements). Pixels can be referred to as ‘dots’ or squares, and these are the basic building blocks of a digital image. When lots of these tiny dots/squares are put together, they form a digital image. Every single pixel has three sub-pixels in red, green, and blue color. Transistors carry electric current to the sub-pixels; this current is why the change of color changes in pixels.

Pixels compose the images displayed on the computer screen, television, laptop, video games, smartphones, and the list goes on. A pixel is the smallest controllable element of an image or display that a computer can print or display.
