As this story breaks, Samsung isin the midst of unveiling its latest flagship phones, theGalaxy S10 and S10+. (Plus thatfoldable phone you may have heard about.) Since we saw the phone ahead of the event, we havehands-on impressions already on the site, but given that we are Engadget, we thought it was worth taking a minute to talk about the screen tech specifically.

This is the company's first phone with a dynamic OLED panel -- technology that Samsung's marketing department is referring to as "Infinity O AMOLED." We're looking at an HDR10+ screen that uses "dynamic tone mapping" to improve the contrast, keep details visible even in dark spots and optimize colors when you're say, watching a movie. Unrelated to that, the screen also reduces blue light by 42 percent in an effort to minimize eye strain. That's not a special night mode, mind you, but the default experience.

And, though it's not obvious to the naked eye, there's also an in-display fingerprint scanner -- a first, Samsung says. In particular, the scanner claims to sense the "3D contours" of your finger, and not just a 2D image. The result, the company claims, is a spoof-proof system.

That's about as much as Samsung was willing to dwell on screen tech during its keynote presentation, but check out our hands-on for a first look, and know that we're taking home a review unit soon and will be giving it the usual in-depth review treatment. In the meantime, let us know in the comments if you have any geeky, super specific questions you'd like us to answer in our upcoming deep dive.
