What are dead pixels?

Dead pixels, also known as stuck pixels, are tiny dots on a display screen that do not properly function. These pixels appear as tiny colored dots that remain either stuck in one color or completely black, regardless of the image being displayed. Dead pixels can occur on various devices, including LED TVs, computer monitors, smartphones, and tablets.

There are different types of dead pixels:

1. Stuck Pixels: Stuck pixels are pixels that remain fixed on a specific color, which is typically different from the surrounding pixels. For example, a stuck pixel might appear as a red, green, or blue dot.
2. Dead Pixels: Dead pixels are pixels that do not emit any light or display any color. They are typically black or dark in appearance and do not change regardless of the image being displayed.
3. Hot Pixels: Hot pixels are pixels that continuously emit light, even when they are not supposed to. These pixels often appear as bright spots on the screen.

Dead pixels can be quite noticeable, especially when they are located in a prominent area of the screen. They can detract from the overall visual quality of your TV and disrupt your viewing experience. While not all dead pixels are easily fixable, there are several methods you can try to revive stuck or dead pixels and restore your TV’s display to its normal functionality.
