Apple Watch 4 with always-on display?

For a long time it was just a hotly debated rumor that the display of the Apple Watch 4 will be around 15 percent larger than its predecessors. A few days ago surfaced (official) marketing material , on which a correspondingly larger display can be seen. Whether this will be 12 percent, 15 percent or 18 percent greater, remains to be seen. It gets bigger in every case. Apple has the right patent in any case ever.

Patent describes improved display for the Apple Watch

The Apple Watch 4 will most likely get a bigger display. Patently Apple draws attention to two patents to cater for just such a display. It is about the better representation of pixels in the edge area as well as a burn-in protection with OLED displays. This burn-in protection is certainly also suitable for an always-on display, so that users can permanently read the time without having to activate the display.

Apple makes the frame thinner around the display, so a larger screen can be accommodated with the same case size. In order to better draw the display in the corners and to ensure good image quality in the frame area, Apple relies on anti-aliasing. Strictly speaking, the whole thing is called Pixel Array Antialiasing. This should ensure that the representation in the border area does not seem too pixelated. In addition to pixels of normal strength, a pixel band with selectively reduced light intensity is intended to visually smooth the content along the edges.

Burn-in effect should be avoided

OLED displays are generally prone to a so-called burn-in effect. Just like the iPhone X. Apple is also concerned with the Apple Watch thoughts on how a branding of the display can be avoided.

Apple uses the patent for a software solution that recognizes how long each individual pixel has already been run on the display. This allows the “consumption” of each individual pixel to be calculated. This results in the expected luminosity at a given time. This information is used by Apple in turn to customize the displayed images individually for the corresponding listening times. At the same time Apple describes a compression method as the data collected to the display consume less memory on the device. Such a technology Apple could use the Apple Watch, at least to display the time permanently on the device.

Although the new patents are only now known, Apple has been working on these technologies for a long time. Although patent 20180246363 entitled “Pixel Array Antialiasing to Accommodate Curved Display Edges” was not submitted until Q2 / 2018, at least bi 2016 is enough. Incidentally, in April this year, another patent was announced, with which Apple also rewrote a bent glass on the Apple Watch.

On September 12, Apple invites to the keynote to Cupertino. Among other things, the presentation of the Apple Watch 4 is expected. How much of the patents mentioned here is already in the upcoming Apple Watch, remains to be seen.
