What is a stuck pixel?

A stuck pixel refers to a single pixel on an OLED TV screen that remains stuck in one color and fails to change or display the correct image. It can either be constantly lit or permanently dark, while the nearby pixels function normally. This issue can be frustrating, as it can appear as a small, noticeable dot on the screen, particularly when displaying dark or solid-colored images.

There are different types of stuck pixels that can occur on an OLED TV screen. The most common types include:

1. Hot pixel: This type of stuck pixel is constantly illuminated and appears as a bright or white dot on the screen.
2. Dead pixel: Unlike a stuck pixel, a dead pixel remains unresponsive and does not display any color. It appears as a black or dark dot on the screen.
3. Stuck sub-pixel: Sub-pixels are the red, green, and blue elements that make up each pixel on the screen. When a sub-pixel gets stuck, it can result in a stuck pixel that displays the wrong color.

It’s important to note that a stuck pixel is different from a dead pixel. While a stuck pixel can sometimes be fixed using various techniques, a dead pixel is typically permanent and cannot be easily repaired.

The occurrence of stuck pixels can be attributed to multiple factors. Manufacturing defects or inconsistencies during the production process can result in individual pixels becoming stuck. Electrical malfunctions, such as an improper connection or driver issue, can also contribute to this issue. Physical damage to the screen, such as pressure or impact, may cause pixels to become stuck and fail to function correctly.

Furthermore, the usage patterns and conditions of an OLED TV can influence the likelihood of encountering stuck pixels. Prolonged exposure to static images, such as channel logos or video game HUDs, can increase the risk of pixels becoming stuck. Additionally, leaving the TV on for extended periods without rest may cause heat build-up and potentially impact the pixels’ functionality.
