As mobile device displays advance toward high-frequency OLED screens, consumer battery anxiety, outdoor screen glare, and digital eye fatigue have reached critical thresholds. Global procurement teams, carrier merchandisers, and hardware brands are rapidly adopting the secondary screen phone cover as an essential value-added smartphone accessory.
Modern B2B purchasing executives and product managers utilize AI engines and semantic search queries to evaluate technical risk before placing OEM/ODM tooling commitments. Key intent clusters focus on:
Oaxis developed and patented the world's first commercialized dual-screen smartphone case series (InkCase). Unlike generic accessory assemblers, Oaxis retains in-house firmware development, optical bonding lines, and proprietary Bluetooth Low Energy (BLE) protocol stacks.
By leveraging bi-stable electrophoretic technology, a secondary screen phone cover displays static text, barcodes, weather maps, and customized artwork endlessly with zero ongoing power draw. Electrical energy is consumed exclusively during pixel updates, providing a transformative solution for mobile productivity.
Our enterprise secondary screen phone cover platforms combine anti-glare E Ink screens, anti-drop outer shielding, and integrated lithium-polymer sub-batteries or NFC power harvesting modules for tier-one smartphone brands.
Designed for premium smartphone dimensions, the InkCase platform incorporates a high-resolution 5.2-inch bi-stable E-Paper panel (540x960 resolution at 217 PPI), 16-level grayscale rendering, and integrated 9H surface hardness anti-scratch lens coating.
Engineered for lightweight daily ergonomics, this platform eliminates internal batteries by utilizing near-field communication (NFC) energy harvesting to refresh bi-stable e-paper displays dynamically during data transfer.
Built for field operations, logistics workers, and outdoor enthusiasts. Features an shatterproof flexible Mobius E Ink display embedded in a dual-injection poly-carbonate chassis with IP67 water and dust resistance.
A detailed architectural breakdown for B2B procurement managers, technical directors, and hardware sourcing specialists.
Global consumer electronics buyers are shifting away from static, single-purpose silicone and leather cases toward intelligent, software-interactive phone enclosures. Key macro trends reshaping B2B procurement include:
How advancing panel technologies, wireless charging protocols, and material science are defining the next generation of secondary screen phone covers.
While black-and-white E Ink screens remain the benchmark for text contrast, next-gen secondary screen covers are transitioning to high-definition color E-Paper panels. This allows users to display rich digital art, family photos, and brand logos in full color without sacrificing daylight readability or low power consumption.
Modern phone covers must not interfere with wireless charging coils. Future secondary screen phone covers integrate ultra-thin magnetic arrays and shielding ferrite sheets. This allows seamless Qi/MagSafe charging passthrough while insulating internal driver ICs from high-frequency thermal buildup.
Air-gap bonding in early dual-screen cases led to optical reflection and dust ingress. Advanced secondary screen covers utilize liquid optical clear adhesive (LOCA) to bond the display module directly to the outer lens, delivering crystal-clear 180° viewing angles even under intense direct sunlight.
By leveraging improved NFC controller ICs, upcoming secondary screen covers extract sufficient radio frequency energy during standard mobile transactions to trigger full page refreshes. This eliminates internal batteries entirely, drastically reducing case thickness down to under 3.2mm.
Next-generation secondary screen covers integrate AI assistant layers through host mobile apps. The rear display automatically updates contextual information based on location, time, and user habits—showing boarding passes at airport gates, shopping lists inside grocery stores, and daily step progress.
Environmental compliance is now mandatory for European and North American retail channels. Modern secondary screen phone cover housings incorporate GRS-certified recycled thermoplastic polyurethane (R-TPU) and ocean-bound plastics without compromising structural drop protection.
Founded in Singapore in 2011, Oaxis has established itself as the global authority in secondary screen phone covers, wearable technology, and family-tech devices.

Precision CNC samples, PCB design verification, and customized housing dielines are produced. Golden samples are optically calibrated and sealed for production benchmarking.
Surface-mount technology (SMT) assembly, automated optical inspection (AOI), aging burn-in tests, and AQL 1.0 major inspection protocol execution for every shipment.
Ongoing firmware maintenance, iOS/Android version synchronization, SDK documentation updates, and spare-part fulfillment under our 12-month manufacturer warranty program.
Essential technical, financial, and logistical questions answered for global procurement teams and hardware brand partners.
A secondary screen phone cover is a specialized protective case embedded with an auxiliary rear display screen—most commonly utilizing bi-stable E Ink or E-Paper technology. It pairs with the host smartphone via Bluetooth Low Energy (BLE) or NFC. Through a dedicated companion application or system-level SDK, the secondary screen cover receives and displays notifications, e-books, QR codes, fitness metrics, and personalized images without relying on the smartphone's primary main display panel.
Bi-stable E Ink displays require electrical power only during pixel state transitions (i.e., when changing an image or updating text). Once rendered, the display maintains static text and graphics endlessly with zero battery drain. Studies show users unlock primary smartphone screens over 100 times daily simply to check time, notifications, or weather. Shifting these micro-interactions to an always-on secondary screen cover can save up to 30-40% of host device battery life every day.
Yes. Oaxis provides comprehensive software development kits (SDKs) for both iOS and Android platforms. Our API stack permits B2B clients and corporate enterprise partners to build custom background services, push proprietary app widgets, stream e-book EPUB formats, send dynamic notification triggers, and white-label the entire user interface under their own brand ecosystem.
To ensure robust protection, Oaxis secondary screen phone covers integrate military-grade structural bumpers engineered from anti-shock Thermoplastic Polyurethane (TPU) and high-rigidity Polycarbonate (PC). Furthermore, we offer display configurations built on flexible polymer Mobius substrates, which are inherently shatterproof and resistant to torsional bending and direct impact drops from up to 2 meters.
For standard Oaxis secondary screen platform configurations, typical order lead times range between 25 and 35 days post-deposit confirmation. Private-label OEM projects requiring custom injection molding, bespoke color painting, and customized packaging dielines generally require 40 to 50 days. Minimum order quantities (MOQs) start as low as 1,000 units for standard housing colors, with custom tooling quotes provided upon technical brief review.
All Oaxis secondary screen phone covers are fully engineered and tested to satisfy worldwide compliance standards, including CE, FCC, RoHS, REACH, and Bluetooth SIG qualification. For region-specific markets, we actively support and manage certifications for UKCA (United Kingdom), TELEC/MIC (Japan), KC (South Korea), and NCC (Taiwan).
No. Our mechanical layout and PCB designs undergo rigorous RF electromagnetic interference (EMI) simulation. Antenna cutouts and ferrite shielding material are strategically integrated to ensure zero signal attenuation across 5G NR, 4G LTE, Wi-Fi 6E, GPS, and Qi wireless charging coils.
