5. Burn-in Mitigation
The potential inclusion of an always-on display feature in iOS 18 presents a notable concern regarding screen burn-in, particularly for devices equipped with OLED (Organic Light Emitting Diode) displays. Burn-in, also known as image retention, occurs when static elements displayed for extended periods cause uneven degradation of the organic material in the OLED pixels. This results in a ghost image of the persistent elements, which can be permanently visible even when the display is showing other content. The longer a static image is displayed and the brighter it is, the greater the risk of burn-in. Given the nature of an always-on display, which continuously presents information such as the time, date, and notification icons, burn-in mitigation becomes a critical component of its implementation.
Several strategies can be employed to mitigate the risk of burn-in. Pixel shifting involves subtly moving the static elements on the screen periodically. This distributes the wear and tear across a wider area, preventing any single pixel from being constantly illuminated at the same intensity. A second approach is to dynamically adjust the brightness of the always-on display based on ambient light conditions, reducing the overall intensity and minimizing the stress on the OLED material. Another tactic involves subtly altering the color of the static elements to vary the usage of different subpixels within the OLED panel. Software algorithms could also be used to intelligently manage the content displayed, limiting the duration of specific static elements and prioritizing dynamic information to reduce burn-in. A real-life example of a mitigation strategy is seen in current implementations of always-on displays that subtly shift the clock or notification elements every minute or so. This invisible change prevents any one pixel from being constantly lit.
Effective burn-in mitigation is essential for ensuring the longevity and user satisfaction with the always-on display feature on iOS 18. Without adequate safeguards, users may experience permanent image retention, which degrades the visual quality of the display and diminishes the value of the device.
