Samsung unveiled a VR-ready display this week that could end up in future flagship phones. The company showed off its new 5.5-inch 4K panel during Display Week in California.

The display packs a whopping 3840 x 2160 pixels, which comes to just over 800 pixels per inch. UploadVR caught the presentation in person and says the 4K panel is “gorgeous.” The report notes that colors and contrast looked great, but the framerate seemed a little low for virtual reality. This is just a prototype, though, so the final version should solve those issues.

It’s tempting to think this 4K display could show up in the Galaxy Note 6 (possibly called the Galaxy Note 7), but that seems unlikely for a few reasons. Multiple reports already suggest Samsung will stick with a Quad HD resolution for at least one more product cycle. The Galaxy Note 7 is also expected to pack a 5.8-inch display while this panel comes in at just 5.5 inches across.

The Galaxy S8 or Galaxy S8 Edge seems like the more likely candidate for this display. The Galaxy S7 Edge already packs a 5.5-inch display so there’s no issue when it comes to size. Samsung will likely also need a big spec upgrade next year after coasting a bit with this year’s Galaxy S7 refresh.

It could also be years before we see Samsung release a 4K smartphone but, as virtual reality continues to gain momentum, the company will need to keep pushing the boundaries. Packing the Galaxy S8 with a super high definition VR-ready display could help the company stay ahead of the pack.
