I Saw a Creaseless Foldable Screen at CES That Could End Up in the iPhone Fold

Samsung Display flexes its latest OLED concepts, and one in particular appeared to be the most promising.

Foldable phones have become thinner, more powerful, and sturdier over the years, but one attribute has remained constant: the crease on the inside display. At CES 2026, I saw a concept that eliminates that center line for a more seamless look.

Samsung Display, which is known for showing off futuristic concepts that may or may not make it out into the real world, showed off a prototype of an OLED foldable display that paints a picture of what may be on the horizon.

Admittedly, all I could think about was whether I’d be seeing something like this in the rumored iPhone Fold, if and when it makes its long-awaited debut.

The company placed two phone models side by side: one that was simply dubbed a «current» device (Samsung Display wouldn’t confirm if it’s the Galaxy Z Fold 7), and another that’s a concept. Looking at the two phones, the difference was striking. When viewing the concept screen directly and at an angle, I couldn’t really see the line down the center that characterizes present-day foldables. The current phone instantly looked outdated.

This is particularly meaningful amid reports that Apple is working with Samsung Display to make a creaseless foldable iPhone. The foldable has been rumored for years, and it appears Apple is taking its time to nail the design, with an emphasis on nixing that pesky crease. Perhaps what I saw at Samsung Display’s booth is a concept that will morph into what Apple equips its iPhone Fold with. But we’ll have to wait until the end of this year at the earliest to find out.

Samsung Display’s creaseless screen is also designed to be more durable. To demonstrate this, the company had a robotic arm fling a basketball at a «backboard» made of several foldable concept phones, and none of them got cracked or dented. I still flinched every time.

The creaseless foldable screen was one of several concepts Samsung Display showed off at CES. The company also had a vehicle mock-up equipped with OLED displays, including a curved, 18.1-inch L-shaped center screen for controlling climate, navigation and more. A 13.8-inch passenger display can move into and out of the dashboard for storage, and there’s an option that prevents the driver from seeing what’s on the passenger’s screen to avoid being distracted.

Samsung Display also had robots that are designed to be teaching assistants. They can guide students to classrooms, share information about professors and display assignments on a circular screen that serves as the «face.» We didn’t really see it carry out commands at the demo, but I was nonetheless enamored by the cute little robotic arms.

Despite all the futuristic notions, the one that stuck with me most was the creaseless display because of its practicality. It’s not clear how many of Samsung Display’s concepts will ever leave the lab, but if any of them do, I hope it’s that one.

Yes, This Swimming RoboTurtle Is Adorable. It Also Has an Important Environmental Mission

Beatbot is best known for making pool-cleaning robots, but it was its swimming robot turtle that won our hearts at CES 2026.

Few things in life have made me feel more privileged and awestruck than the opportunity to swim with sea turtles in their natural environment. The way in which these gentle creatures navigate through their underwater world with their deliberate and careful fin strokes is utterly mesmerizing to watch.

It’s a distinctive style of movement — so much so that when I saw Beatbot’s RoboTurtle swim across a water tank on the show floor at CES 2026, I knew that this wasn’t simply just a pool cleaner robot with turtle features tacked on. This was a studied example of biomimicry in action.

The reason for this is that the company’s engineers went on a two-month expedition to study sea turtles in their natural environment, Beatbot’s Eduardo Campo told me as we watched Turtini (the team’s affectionate nickname for RoboTurtle) splash around in its pool. «We did a lot of motion capture, like the things they use in movies, because we need to develop those joints that it has,» he said.

This isn’t RoboTurtle’s first time at CES — it also appeared in 2025 as a static concept. This is the year, however, it’s found its fins, so to speak. Not only can it swim, but it can also respond to hand gestures: I throw it an OK gesture, and it dances in response. But as cute and limber as it is, RoboTurtle is a robot with an important mission.

RoboTurtle is an environmental research tool, built with input from researchers and NGOs, which can go where humans or other machines cannot for fear of disturbing complex and delicate underwater ecosystems, particularly coral reefs. It can move silently and naturally in a way that won’t scare wildlife, monitoring water quality and fish numbers with its built-in camera.

«One of the groups that we’re working with, they want to study the coral reefs in near Indonesia,» said Campo. «There was a very big incident over there with a boat that came up onto a coral reef and it disrupted the environment, [so] they want the least intrusive robot possible.»

The group wants to deploy RoboTurtle for certain periods every year to monitor the recovery of the coral and monitor the fish population, he added. Beatbot is currently training the built-in AI to give RoboTurtle monitoring and recognition skills.

At CES, I watched RoboTurtle paddle about only on the surface of the pool, but it can also dive down up to five meters. However, it needs to resurface to send data and its GPS signal back to base, much like a real turtle that needs to come to the surface to breathe. This also gives it a chance to recharge via the solar panel on its back.

Even though I was impressed with RoboTurtle’s swimming ability, Campo estimates that the Beatbot team is still a year and a half away from perfecting its technique, with the robot ready for full deployment in between three to five years.

CES 2026 is a show where tech with a real purpose feels scarce, so it sure is refreshing to see a company use its expertise to build something designed with a sustainable future in mind. It might be a while until we see RoboTurtle take to the seas, but I’m glad that I got to witness it at this stage of its journey.

These Tiny Robots Are Smaller Than Grains of Salt and Can Think, Move and Swim

Despite their size, the robots can navigate liquids, respond to their environment and operate without external control.

Robots smaller than a grain of salt? It sounds like science fiction, but researchers have developed autonomous microrobots that can move through liquids, sense their environment and operate independently using only light as a power source.

The microrobots, developed by researchers at the University of Pennsylvania and the University of Michigan, measure roughly 200 by 300 by 50 micrometers. Yet they can detect temperature changes, follow programmed paths and function independently for months at a time.

Their work was reported this week in two scientific journals, Science Robotics and Proceedings of the National Academy of Sciences.

«We’ve made autonomous robots 10,000 times smaller,» senior author Marc Miskin, assistant professor in electrical and systems engineering at Penn Engineering, said in a statement. «That opens up an entirely new scale for programmable robots.»

Powered entirely by light, the robots don’t move using mechanical limbs. Instead, they generate tiny electrical fields that push ions (electrically charged particles) in fluid to create motion, an approach better suited to the unique physics of the microscopic world, where traditional motors don’t work.

Unlike earlier microrobots, these devices combine sensing, computing, decision-making and movement in a single, self-contained system at an extremely small scale.

Previous efforts in microrobotics have often relied on external controls, such as magnetic fields or physical tethers, to guide movement. These new microrobots, however, incorporate their own miniature solar cell-powered processors, allowing them to respond to their environment, communicate through patterned movements visible under a microscope and carry out tasks without outside direction.

Potential applications include monitoring biological processes at the cellular level, supporting medical diagnostics or helping assemble tiny devices. Because each robot can be mass-produced at very low cost, the technology opens new avenues for research and engineering at scales that were previously unreachable.
