It is linked to mobile devices however, with the application stating the feature relates to "computer application software for smartphones, mobile phones, and tablet computers, namely, software for personal information management, and for monitoring, synchronizing and viewing updated information regarding time, date, weather, news, messages, schedules, health, and fitness program."
Side screen action?
The information to be displayed on the always-on display listed in the filing certainly makes sense. It's data we've already seen appear on lock screens, and more recently along the edge screen of the Galaxy Note Edge, Galaxy S6 Edge and S6 Edge+.
This could be our first sign of a more integrated edge screen for future curved Samsung phones and tablets (Samsung Galaxy S8 Edge, anyone?), where the slender strip of screen never turns off completely, keeping you constantly updated with notifications.
Alternatively, Samsung may be working on a full screen standby mode which sees information displayed as part of a low power theme - or perhaps we'll even see a second screen like the Yotaphone 2's additional E-Ink display.
We hope this means Samsung has also found a way to decrease the power consumption by the display, otherwise this feature could well be very short-lived. Either way, we're excited to see this feature come to fruition, if it ever does.
