Aiming for longevity as much as possible.
This October Nintendo will be launching a new model of the Nintendo Switch, which will feature a new OLED screen.
While a rare occurence OLED screens can experience a burn-in. A burn-in is when a part of an image remains permanently on screen, something that doesn’t happen with normal use, and is caused if a static image remains on screen for several hours, which leads to a permanent degradation of pixels.
To prevent this from occurring Nintendo had the following to say:
“We’ve designed the OLED screen to aim for longevity as much as possible, but OLED displays can experience image retention if subjected to static visuals over a long period of time. However, users can take preventative measures to preserve the screen [by] utilizing features included in the Nintendo Switch systems by default, such as auto-brightness function to prevent the screen from getting too bright, and the auto-sleep function to go into ‘auto sleep’ mode after short periods of time.”
