Dead pixels are tiny points on a screen that are permanently stuck on or off, resulting in a noticeable defect. While it's a common concern, dead pixels generally don't increase over time.
Here's why:
- Physical Defect: Dead pixels are caused by a physical defect in the screen's circuitry, often occurring during the manufacturing process. These defects are permanent and don't worsen with time.
- Pixel Burn-in: Pixel burn-in is a different issue where a static image remains visible on the screen even after the image is removed. This is caused by prolonged exposure to bright, static elements and is not the same as dead pixels.
- Screen Degradation: Over time, screens can experience general degradation like color fading or brightness loss. These issues are related to the screen's aging and not the formation of new dead pixels.
However, there are exceptions:
- External Damage: Physical damage to the screen, such as a drop or impact, can cause new dead pixels to appear.
- Manufacturing Defects: Some screens might have latent manufacturing defects that manifest as dead pixels over time, but this is less common.
In conclusion, while dead pixels themselves don't typically increase over time, they can appear due to external damage or latent manufacturing defects.
