Apple Works to Avoid Screen Burn-in On Apple Watches

Share:
Published on July 10,2020

New proposals from Apple may see always-on Apple Watch faces alter their images to avoid old-style screen burn-in.

The Apple Watch is about as far away as you can get from devices like the Macintosh SE/2 and Macintosh IIfx of the last century, but it seems it could be prone to a problem that dogged those and all computers with CRT screens. Apple wants to make sure that an image which stays on screen for a long time, doesn't damage the display and appear to stay there forever.


It's likely that at least some of these are already present in the Apple Watch Series 5, if not earlier models, but this is the first time solutions have been presented.In theory, this could affect iPhones or iPads which display the same app icons in the same place. However, those devices go to sleep when not used and the Apple Watch is now able to show at least some elements all the time, and so greatly increase the risk of burn-in.

The whole application is about how Apple can electronically mitigate the problem by balancing what it calls "dwell time," the time a user spends actually looking at a screen, and reducing the intensity of that display.

So Apple's proposal is to have the Apple Watch adjust the position on screen of key elements. It may be so subtle that it isn't immediately obvious, but Apple plans "repeated radial inward and outward movement" to spread "out the pixel wear."

Regrettably, nowhere in the patent application does it suggest giving us After Dark-style screensavers for our Apple Watches.
