What is screen burn and how does it occur?
Screen burn, also known as image retention or ghosting, refers to the permanent or temporary discoloration of a screen due to the prolonged display of a static image. This phenomenon occurs when a particular image is displayed on a screen for an extended period, causing the pixels to become fatigued and retain a ghostly impression of the image. The likelihood of screen burn increases when the same image is displayed at high brightness and contrast levels, as this puts additional stress on the pixels.
The risk of screen burn is higher in certain types of displays, such as organic light-emitting diode (OLED) panels, which are commonly used in modern smartphones, TVs, and monitors. This is because OLED panels use an emissive technology, where each pixel emits its own light, making them more prone to image retention. In contrast, LCD panels, which use a backlight to illuminate the pixels, are less susceptible to screen burn. However, it’s essential to note that screen burn can still occur on LCD panels if they are subjected to extreme usage conditions, such as displaying a static image at high brightness for an extended period.
