### The Spark of Inspiration

Ledger Stax, featuring the world’s first curved E Ink® touchscreen, was born from a bold ambition to redefine both security and user experience in hardware wallets. Early Ledger products like the Nano series, while secure, felt akin to clunky USB drives—marred by cumbersome operations and rudimentary displays. After their 2018 launch, CEO Pascal Gauthier resolved to pivot: he brought on Ian Rogers, a former Apple executive, as Chief Experience Officer. Together, they envisioned merging E Ink’s strengths—crystal-clear, persistent visibility and ultra-low power consumption—with a naturally contoured curved touch design. The result? An intuitive, fluid user experience that transcended the "functional tool" label, transforming hardware wallets into user-centric devices.

### Breaking New Ground with Curved OTFT Displays

Ledger Stax stands out for its pioneering curved OTFT (Organic Thin-Film Transistor) display. By depositing E Ink layers onto a flexible plastic substrate instead of traditional glass, the team created a bendable, shatter-resistant screen with built-in touch capabilities. Compared to glass-based displays, OTFT manufacturing slashes process temperatures from 350°C to under 100°C, drastically reducing energy use. This breakthrough enables the screen to stay perpetually lit with minimal power—users can check their crypto balances directly on the device without connecting to another gadget.

### Three Core Design Principles

- **Form Innovation**: Credit-card sized (85mm x 54mm) with a magnetic "stackable" design (hence "Stax," from "stack"). It doubles as a personalized display for NFTs or photos.

- **Simplified Interaction**: Setup takes ≤3 minutes. The E Ink screen supports touch and constant visibility, letting users check balances offline.

- **Seamless Transactions, All on One Screen**:

- Verify details (recipient address, transfer amount)

- Biometric confirmation (via Bluetooth-linked mobile app for one-tap signing)

- Magnetic stacking: Multiple devices snap together magnetically, enabling unified management of multi-chain assets (supports 5,500+ tokens including BTC/ETH).

- **Emotional Connection**: The curved side, resembling a book’s spine, accepts custom labels, infusing the device with personality.

These features strip away the "tool-like" feel, turning Stax into a secure vault for crypto assets—one that’s energy-efficient, merges touch functionality with secure elements, and balances utility with aesthetics, making it a true consumer electronics standout.

### Redefining Hardware Wallets on Three Fronts

Ledger Stax isn’t just a response to user frustrations; it’s a bold push at the edges of technology. It reconstructs hardware wallets across dimensions:

- **Design**: Infusing consumer electronics logic into security hardware, giving cold private key management a human touch.

- **Technology**: The OTFT flexible screen marks a turning point—E Ink is no longer confined to flat displays but free to take diverse forms.

- **Philosophy**: Post-FTX collapse, market demand surged, underscoring a truth: as digital asset risks grow, physical-level security paired with user-friendly design becomes non-negotiable.

Stax’s journey—from "geek tool" to mass-market product—weaves together a revolution in design philosophy, breakthroughs in materials science, and the crypto world’s dual hunger for safety and simplicity. Its innovation isn’t just in hardware; it redefines what self-custody of digital assets *feels* like.

- DKE developed the world’s first 180° bending lamination process, solving the problem of circuit integrity under extreme bending and ensuring uniform display quality.

- Structurally, it adopts an "all-plastic architecture" (PEN flexible substrate + FPL ePaper film), replacing traditional etched TFT hard boards and integrating "flexible bending + touch functionality" into one.

#### Performance Leap: Redefining ePaper Boundaries

Ultra-low power consumption: Equipped with Eink’s ePaper display film, the screen features bistable properties (users can customize personalized images in shutdown or standby mode), consuming only 1/1000th of the power of traditional solutions.

### Challenges from Lab to Million-Scale Production

#### The Battle for Yield in 180° Bending Lamination

Extreme bending significantly increases the risk of circuit breakage. DKE addressed this by developing precision multi-layer film lamination technology and flexible circuit compensation designs, dispersing stress in the bending area and raising mass production yields to a commercially viable level.

#### Vertical Supply Chain Integration

Since establishing its flexible ePaper R&D team in 2022, DKE has collaborated with material suppliers and equipment manufacturers to build a closed-loop supply chain, shortening the cycle for technology commercialization.

(First Publish: 2025)An ePaper full-color variable "decorative wall" that transforms our

Tue, 22 Jul 2025 08:46:10 +0800

In today's world swept by the digital wave, Seekink Technology has achieved a groundbreaking new application scenario after three years of dedicated efforts - the Prism Mosaic Decorative Wall Technology. This is more than just a color-changing wall; it's a revolution in spatial aesthetics and a leap forward in ePaper display technology.

In June 2022, when the R&D team of Seekink first put forward the concept of "color-changing tiles", it sounded like a fantasy. At that time, the ePaper technology on the market was still in the stage of small-size and black-and-white display. To realize large-size, color, and spliceable wall display, it faced multiple technical bottlenecks in materials, processes, driving, and software. After three years of technological iteration, from the first - generation Prism1 spliced color-changing tiles to the current third - generation Prism high-resolution splicing screen, which uses PVI's most advanced prism3s color ePaper film, the module thickness is less than 1mm, the weight is no more than 200g, and it can achieve full-color display while maintaining ultra-low power consumption. This material remains clearly visible even in strong light and does not cause any blue light damage. In terms of craftsmanship, through an innovative narrow - edge design, the splicing gap is controlled to less than 5mm. Coupled with the intelligent pixel compensation algorithm, the display effect of the entire wall is integrated. This process makes large - size art walls possible. The drive system R&D team has created a distributed drive architecture, where each module works independently and collaboratively. Most amazingly, a 10 - square - meter ePaper splicing wall can be powered by just one power bank. In terms of software intelligent interaction, the supporting Prism App supports iOS and Android systems. Users can upload pictures at any time, set playlists, and adjust dynamic effects through their mobile phones. The system also supports multi - person collaborative editing, making creation much easier.

The new - generation Prism spliced decorative wall technology redefines spatial aesthetics. In home application scenarios, in the past, changing decorative paintings required climbing up and down, but now customers can change wall patterns through their mobile phones at any time. In the morning, it can be a fresh landscape painting, in the afternoon it can be changed to abstract art, and in the evening it can become a starry night scene. One wall can create the atmosphere of the whole home. In commercial office application scenarios, it can be switched to a project schedule, a brainstorming whiteboard, or a relaxing landscape painting at any time, maximizing work efficiency and creative atmosphere. In retail advertising application scenarios, using Prism walls instead of traditional windows to display different products every day according to changes in customer flow can increase customer traffic.

The new - generation Prism spliced decorative wall technology redefines low - carbon display. ePaper display technology, which represents the future direction of green display, is receiving more and more attention. Compared with traditional LED displays, the energy consumption of Prism walls is only 1/1000 of the former. Calculated based on a 10 - square - meter wall, it can save about 3000 kWh of electricity per month. What's more valuable is that ePaper only consumes power when switching images and has zero power consumption during static display.

The future of Prism spliced decorative wall technology will witness more innovations. For example, with the prism flexible ePaper film module, curved wall designs can be realized in the future. With the support of an AI intelligent recommendation system, wall patterns can be automatically generated according to users' preferences. And by combining touch interaction functions, the wall can directly become a giant touch screen. Seekink's prism spliced decorative wall technology is redefining the concept of 'wall'. The future wall will be intelligent, interactive, and environmentally friendly, and it will become an intelligent interface connecting people and space.

From the first - generation black - and - white color-changing tiles to the third - generation full - color intelligent art walls, Prism technology has completed a perfect evolution in three years. This is not just a technological breakthrough, but also opens a new era of space design. When the wall can change at will, our living space will also have unlimited possibilities. In front of this thinking wall, we see not only the progress of technology but also the unremitting pursuit of a better life by Seekink people. Prism spliced decorative walls are using technology to re - describe the way people talk with space.

Acquaintance: A Corridor Encounter in the Science Park

In early 2023, E Ink was searching for the next-gen "wireless brain" for ePaper, while Realtek was testing a Bluetooth LE SoC (System-on-Chip) supporting BLE/15.4 ultra-low power. That spring, during a break at the Touch Taiwan "Wireless Display Technology Forum," an E Ink engineer posed a question to Realtek's BLE product director: "How about embedding RFIC directly into glass?"

"Integrating RF functionality into glass panels could let 'Panle ePaper shelf labels' break free from rigid boards, shrink in size, simplify assembly, and cut costs—interested?" This question kicked off their collaboration. Two years later, in spring 2025 at Touch Taiwan, the first technical flower of their "Blue Ink Duet" bloomed, heralding a vibrant future for ePaper product design.

Alchemy: The Deep Dance of ePaper and RF Technology

The challenge wasn't just "attaching" the SoC to glass but overcoming mechanical and antenna constraints. Starting from packaging design, they used E Ink's thin-film technology as part of the antenna matching network, 重构从焊线到内层微带结构 (rebuilding from wire bonding to inner microstrip structures) to achieve deep integration of RF and display.

Thermal Stress: Circuit packaging temperature difference controlled within ±5°C.

RF Noise: Solved 2.4GHz band noise spikes from ePaper's high-voltage driving scans.

Thickness Threshold: Total stacking thickness <220 microns to pass 100,000 bend cycles.

Forging: Birth of System-on-Panel (SoP) Technology

In March 2025, the duo unveiled the "2nd-Gen SoP ePaper Tag," grabbing industry attention. With wireless signals and pixels merged into a single carrier, every display becomes a communicative smart ePaper terminal. This collaboration—rooted in technical complementarity, geographic proximity, and shared market vision—isn't just a product upgrade but a cross-disciplinary innovation model:

30% reduction in TFT area, 50% smaller FPC; world’s first RFIC directly embedded in glass.

2.66-inch ESL (Electronic Shelf Label) standby current <1.56 microamps.

Spark: Accelerating Market Adoption

ePaper shelf labels have already replaced traditional paper labels for efficiency and low power, but E Ink-Realtek collaboration pushes further:

Technical Leap: SoP on ePaper panels optimizes circuit layout and transmission lines, matching traditional labels' signal range for commercial use. FPC stacking on the panel back reduces size and material consumption, aligning with ESG sustainability.

Sun, 06 Jul 2025 11:42:13 +0800

The park's sunset gilds the grass in gold, and cookie crumbs still scatter on the picnic mat. A young mother hurries away, pulling her child's hand, as laughter fades into the distance. It's not until they get home that the child's tearful cry pierces the air: "Mom, where's my little backpack?"—inside lie the favorite stuffed animal and a vibrant "family portrait" just painted. The mother's heart tightens as she frantically scrolls through her phone album, trying to locate that patch of grass, anxiety swelling like a tide. Meanwhile, on a park bench, a kind tourist picks up the colorful bag. He looks around for the owner, but finds no contact info inside or out. "Such an important thing—how worried the child must be? But who should I call?" He holds the backpack, equally helpless.

In a street-corner bubble tea shop in the city, sweet aromas linger. A traveler rests and then blends into the bustling crowd. Moments later, she realizes with a jolt: her carry-on bag with passport, ID, and itinerary lies forgotten on a corner seat! In a foreign land, the tedious process of replacing documents could derail her meticulously planned trip. She anxiously searches online for the shop's number, fingers icy. At the same time, a staff member finds the lonely bag. He dutifully checks every compartment for a business card or clue, but finds nothing. The documents are within reach, yet the path to return them seems endless.

Late at night, city neon flickers. A weary businessperson steps out of a taxi, rubbing his aching temples, and heads home. It's not until the next morning, when preparing documents, that he's struck with horror—the briefcase containing vital business contracts is still in the taxi's back seat! He dials one taxi company after another, describing the vehicle, but it's like searching for a needle in a haystack. On the other end of the city, the night-shift driver finds the case while cleaning. He knows the documents are crucial, but looking at the flowing traffic, "No name, no phone—how can I find you?" Goodwill is mercilessly blocked by an information divide.

These scenarios aren't dramatic fictions but real-life predicaments repeatedly observed by the Moxiao Jia team during their in-depth study of modern life. Traditional positioning technologies solve "where is the item," but fail to answer the simpler question in the finder's mind: "Whose is this? How to return it?" Between tech's one-way tracking and humanized return lies a cold barrier.

The birth of the color display locator Reink Tag aims to dismantle this barrier entirely. Its core lies in the unique 1.54-inch four-color ePaper screen—rare among locators. The value of this screen extends far beyond display; its physical feature of "always-on zero power consumption" is key—once information is shown, it stays stable without consuming a single watt. This means no matter how long the item is lost or who finds it, the owner's contact info (or preset key details) remains clearly visible, like a silent and loyal messenger. Park visitors, bubble tea shop staff, or night-shift drivers need no charging ports, network connections, or specific apps—just a glance to get the key to return the lost item.

Static display, however, is insufficiently flexible. Users may need to update phone numbers or set more eye-catching prompts for specific items (like the child's painted backpack). This is where another core technology of the color display locator—NFC near-field communication image transmission—shines. Its ingenious design perfectly resolves the contradiction between "updating information" and "ultra-long battery life." When users need to change the screen content, they simply open the phone app and bring the phone close to the locator. At the moment of NFC contact, the phone doesn't just transmit data—it "feeds" the screen a bit of power, providing the微量电力 (minimal power) needed to refresh the ePaper display. This process doesn't consume the locator's built-in button battery at all. This patented mechanism of "borrowing power to update images" ensures a 700-day ultra-long battery life, allowing information flexibility without sacrificing core functions.

The color display locator understands that losses often happen unexpectedly and in challenging environments. Thus, extreme protection is the cornerstone of its reliability:

- **IP68+ True Waterproof & Dustproof**: Using a hermetic sealing process comparable to bank cards, it ensures the locator can withstand immersion in 1.5 meters of water for 1 hour—whether a picnic backpack is soaked by spilled drinks, a briefcase falls into a puddle, or a bubble tea cup tips over inside a bag—continuously safeguarding key info.

- **2.5m Drop & Impact Resistance**: The high-strength PVC shell, rigorously tested, withstands drops from heights (e.g., a child's backpack) or bumps during luggage handling, protecting internal components.

- **Smooth Matte Finish**: The surface treatment resists daily scratches from keys or coins while offering a comfortable touch, ensuring durability.

Integration with Apple's Find My network (MFi certified) provides precise positioning, loss alerts, route navigation, and ring finding—basic functions of a modern locator. But its true value extends further. In park, bubble tea shop, or taxi scenarios where the Find My network might fail (due to no Apple devices or Android users), the ePaper screen of the color display locator silently persists—serving as the "ultimate insurance" across the information divide. It enables the tourist to call the mother immediately, allows the staff to contact the anxious traveler without guesswork, and helps the driver return the vital contract swiftly.

Through the color display locator, Moxiao Jia aims to convey not just a product but a solution philosophy: Technology should not only serve one-way searching but also pave a clear path for goodwill-driven returns. That always-on ePaper screen is a warm bridge connecting the owner's anxiety with the finder's kindness. It turns loss from a powerless wait into a scenario where every act of honesty can easily become a reassuring call and a heartwarming conclusion.

When an item strays, the color display locator makes return traceable and goodwill unblocked. This, perhaps, is technology in its warmest form.
