Introduction to Dead Pixels
A dead pixel is a pixel on a phone’s screen that does not display the correct color or remains black, affecting the overall visual quality of the display. Pixels are the tiny units that make up the images on your screen, and when one or more of these pixels malfunction, it can be quite noticeable, especially on high-resolution displays. Dead pixels can appear as small black dots or white spots, depending on the type of defect.
Types of Dead Pixels
There are primarily two types of dead pixels: hot pixels and dead pixels. Hot pixels are pixels that are always on, displaying a bright, usually white, color.
