In this article, we will delve into the world of burn-in, exploring what it is, how it occurs, and whether you should be worried about it.
What is Burn-In?
Burn-in, also known as image retention, refers to the permanent ghostly impression of a static image that remains on a display even after the image has changed. This phenomenon is not new and has been observed in various types of displays, including plasma TVs, OLED (Organic Light-Emitting Diode) panels, and even some LCD (Liquid Crystal Display) screens. Burn-in occurs when a static image is displayed for an extended period, causing the pixels to degrade unevenly. As a result, the affected pixels can become permanently damaged, leading to a ghostly impression of the original image.
Causes of Burn-In
Several factors contribute to the occurrence of burn-in. Static images are the primary cause, as they can cause uneven pixel degradation. This is particularly true for images with bright, static elements, such as channel logos, menus, or video game HUDs (Heads-Up Displays). Display technology also plays a significant role, with OLED panels being more susceptible to burn-in due to their organic material. Additionally, usage patterns can increase the risk of burn-in, such as leaving a static image on the screen for extended periods or using the display in a way that causes excessive wear and tear.
Types of Displays Affected by Burn-In
While burn-in can occur on various types of displays, some are more prone to this phenomenon than others. OLED panels are particularly susceptible due to their organic material, which can degrade over time. Plasma TVs were also known to suffer from burn-in, although this technology has largely been replaced by newer display types. LED/LCD screens are generally less prone to burn-in, but can still be affected under certain conditions.

What is burn-in and how does it affect displays?
Burn-in, also known as image retention, is a phenomenon where a static image is permanently etched into a display, causing a ghostly impression to remain even after the image has changed. This occurs when a display is showing the same image for an extended period, causing the organic compounds in the display’s pixels to degrade and retain the shape of the image. Burn-in can be particularly noticeable on OLED and plasma displays, which are more prone to this issue due to their technology.
The effects of burn-in can be subtle at first, but over time, they can become more pronounced and distracting. In severe cases, burn-in can render a display unusable, as the retained image can be visible even when the display is showing a different image. However, it’s worth noting that most modern displays, including OLED TVs and smartphones, have features and technologies in place to mitigate burn-in, such as image retention compensation and pixel shifting. These features can help reduce the risk of burn-in, but they may not completely eliminate it.
What causes burn-in on displays?
Burn-in is caused by the degradation of the organic compounds in a display’s pixels, which occurs when a static image is displayed for an extended period. This degradation can be accelerated by various factors, including the brightness and contrast of the image, the temperature of the display, and the age of the display. Additionally, certain types of content, such as static logos, menus, and graphics, can increase the risk of burn-in due to their static nature. Displays that are used for gaming, video streaming, or other applications that involve static images can also be more prone to burn-in.
To minimize the risk of burn-in, it’s essential to take steps to reduce the degradation of the organic compounds in the display’s pixels. This can be achieved by adjusting the display’s settings, such as reducing the brightness and contrast, and using features like screen savers or pixel shifting. Additionally, using a display with a high-quality panel and proper calibration can also help reduce the risk of burn-in. By taking these precautions, users can enjoy their displays without worrying about the negative effects of burn-in.
