Samsung has generated substantial buzz at the 2024 Consumer Electronics Show (CES) in Las Vegas by unveiling several groundbreaking new foldable smartphone concepts. These innovative prototypes point to a future of bendable, rollable, and stretchable mobile devices offering unprecedented versatility and utility.
Foldable Flip Phone Bends Both Ways
The most eye-catching concept shown by Samsung is a flip phone design that can fold both inward and outward. Most current foldable phones like the Galaxy Z Flip bend inward, with the display on the inside. But Samsung’s new prototype allows the flexible screen to flip a full 360 degrees.
This gives users the option to have the display facing outwards even when closed. The exterior screen could show notifications, widgets,caller ID and more. Then with a quick flip, the large internal screen unfurls for full smartphone utility.
Flexible Glass Substrate Enables Two-Way Folding
What makes the bi-folding design possible is Samsung’s new ultra thin glass (UTG) substrate and advanced hinge mechanism. The UTG is bendable enough to allow outward and inward bends to a very tight radius without damage.
Samsung Foldable Display Specifications
UTG Thickness: 30 microns
Minimum Folding Radius: 1 mm
Display Size Folded: 4 inches
Display Size Unfolded: 6.8 inches
Resolution: 22:18 aspect ratio equivalent to unfolded display
This builds on existing UTG technology found in current folding phones like the Z Fold 4. But enhancements allow a folding radius of just 1 mm while maintaining resilience of over 200,000 folds.
Enhanced Durability, Visuals
The new twice-bending displays also showcase Samsung’s latest foldable cover window material. This offers enhanced scratch resistance and durability compared to the polymer substrates used currently.
Samsung says the dual-bend technology will come in at parity cost wise with standard flexible displays. Resolution is maintained whether the screen faces inward our outward. And the unique form factor lends itself to innovative UX, especially for multitasking.
AI Optimizes App Usage Across Configs
To take advantage of the dynamic configurations, Samsung has developed predictive AI that customizes app layouts. This allows seamless transitioning between folded and unfolded modes.
So apps intelligently rearrange themselves, continuing video playback even as the phone flips around. The AI also suggests optimal app splits for video calling, social feeds, browsing and more.
Rollable Display Extends Sideways
Along with the flip prototype, Samsung demoed an extendable display variant. This concept uses a slidable mechanism to unfurl the flexible OLED panel horizontally.
Fully retracted, it operates as a normal candy bar style phone. But the sides can unroll additional display real estate up to a tablet sized 10+ inches diagonally. This creates a huge canvas for immersive gaming, video watching or multitasking.
The rollable concept leverages Samsung’s sliding Under Panel Camera. So despite the variable width, the camera stays centered underneath the display. Samsung says its etching process also allows uniform visuals across the sliding portion.
Cinematic 22:18 Aspect Ratio
Many of Samsung’s new bendy prototypes feature an extra wide 22:18 aspect ratio designed specifically for movies. This cinematic format is much wider than current smartphone displays.
So letterbox bars are minimized for a more immersive experience watching films shot natively in 21:9. Samsung is also working with leading content creators to adapt media for the ultra-wide dimensions.
Breakthrough Foldable Tablet Also Unveiled
Beyond phones, Samsung provided the first glimpse of its trailblazing tri-fold tablet. Using an advanced multi-hinge system, the device folds down to typical smartphone size.
But unfurled it reveals a full 12.4″ tablet display, rivaling an iPad for real estate. The revolutionary concept leverages Samsung’s most advanced flexible display innovations to create an entirely new mobile form factor.
Next Generation Flexible Materials
Samsung confirmed the foldable tablet incorporates next-gen materials like sliding glass and harder ultra thin glass. It also debuts a new aluminum-based alloy Samsungdeveloped specifically for intricate folding mechanisms.
Called Barium, the material is lightweight yet over 50% stronger than standard alloys. This allows complex multi-fold movement while retaining rigidity in flat configuration.
2025 Launch Targeted
While still early stage prototypes, Samsung’s foldable chief says commercialization is steadily progressing. The goal is to bring select models outlined above to market by 2025.
Industry sources indicate the unique expanding display concepts face the biggest hurdles. But the technology is rapidly maturing, with fold resistance and seamlessness improving monthly.
If Samsung meets its launch targets, the smartphone landscape may look radically different just two years from now.
Foldables Moving to Mid Range
Samsung also revealed plans to bring foldable technology to cheaper price points by 2025. Interface improvements allow eliminating the mechanical side bezels on budget models. This helps slash production costs significantly.
Entry level foldables would grow the niche category’s market share exponentially. And Samsung’s vertical integration makes it best positioned to own this foldable future as prices eventually dip below $1000.
With rivals like Apple yet to unveil foldables, Samsung’s first mover advantage gives it multi-year expertise lead. The new concepts revealed look to push boundaries even farther over coming years.
Conclusion: Folding Goes Mainstream
In showing its latest innovations, Samsung asserts that foldables are nearing the tipping point of mass adoption after years of steady progress. As materials improve and costs decline, unique form factors like outward folding flip phones will profoundly expand mobile utility.
Within the next 2-3 years, folding devices are primed to go from niche to normal. And Samsung has clearly telegraphed its plans to remain years ahead of competitors. With the stunning designs previewed here, the future promises ever more productive, versatile and sleek mobile devices.
What Comes After Folding?
With foldables becoming almost commonplace by 2025, eyes are already turning to what’s next. Early stage research shown by Samsung suggests expanding beyond folds to stretchable and slidable designs. These dynamically shape-shift depending on use context and content type.
Samsung calls this adaptive concept “Mutable” – displays that physically morph in users’ hands. Engineers are already actively prototyping tablet sized panels that dynamically expand or curve themselves around objects.
This hints that while revolutionary, foldables may simply be the beginning of a more profound mobile transformation. One where devices break free of static slabs and transition towards almost living adjustability.
Samsung Pursues Next Generation Display Materials
In powering its bleeding edge prototypes, Samsung indicates significant resources dedicated towards breakthroughs in material engineering and nanoscale manufacturing.
Beyond obvious advances in bendable substrates, Samsung discussed progress on several next-gen display technologies it sees critical for future devices.
Self-Healing Polymers Automatically Repair
One futuristic concept highlighted is self-healing displays under development by Samsung Display. This incorporates custom polymers that can automatically repair microscopic scratches and defects within flexible OLED panels.
The polymers reconnect and reseal gashes up to several millimeters through capillary action along optimized microscopic channels. Resulting repairs approach 90-95% restitution with full strength restoration over 12 hours.
AI Pixel Shifting Combats Burn In
Samsung also revealed new AI-powered anti burn in tech coming to 2025 foldable models. Dynamic software shifting imperceptibly modulates pixels to evenly distribute wear. User tendencies like keeping certain UI elements static are analyzed to target shift balancing.
This build on existing pixel refresh methods by tailoring to actual usage profiles. Early testing shows substantial reduction in differential degradation among OLEDs.
New Ultra-Efficient Emitting Materials
But much research remains cloaked until commercialization nears. Samsung Display CEO JS Choi teased “very promising developments” in new metal complex emitters and organometallic compounds being synthesized. These could revolutionize manufacturing throughput and substantially lower display power budgets.
Engineers are also actively prototyping backplane architectures incorporating novel 2D semiconductors like WSe2 or MoS2. Large area processability remains challenging. But transistor densities could multiply exponentially enabling uptimes of weeks on smart devices.
Industry rumors even suggest experiments with quantum dot integration into blue OLED films at Samsung Advanced Institute of Technology. This could enable over 150% BT.2020 gamut while requiring one third the power.
The Future: Nano-Engineered Displays
All indications point to Samsung aggressively pioneering display innovation into realms approaching science fiction. Expect nanoscale manufacturing breakthroughs enabling unforeseen functionalities as screen sizes expand.
By last half of this decade, mobile displays could boast unimaginable brightness, efficiency and interactivity approaching biological capability through discovered material phenomena. Samsung’s dominance seems certain to continue absent a fundamental shift across the entire electronics supply chain.
