InkJoy Partner Platform
If you do not have hardware yet, start with InkJoy-proven devices and the full platform, then build your own branded app.
If you already have hardware, license only the parts you need: Device RTOS, cloud / IoT, Merchant API, or ISFR.
From product to platform
All of our capabilities — Device RTOS, cloud services, ISFR rendering, and Merchant API — have already run for the long term inside InkJoy complete products, with real users, real networks, and real content.
What partners receive is an end-to-end delivery stack with industry-leading image quality, stable cloud distribution, and low-power operation. You can focus on product form, brand experience, and what content to show, instead of rebuilding the hard parts of ePaper from scratch.
The stack
These layers cover the device, the cloud, image rendering, and business integration. Use the full stack, or license only the layer your product is missing today.
Device-side software based on FreeRTOS, handling standby, connectivity, refresh, health checks, and OTA. Built for ePaper devices that need long standby, stable Wi-Fi, and reliable content delivery.
Device management, content delivery, offline cache, OTA, monitoring, SSO, and merchant roles. Proven in InkJoy products and ready to connect with partner hardware.
ISFR is not a simple filter. It is a rendering workflow for color ePaper that adjusts enhancement, color, and dithering based on the content, so images look more natural on Spectra 6.
Merchant API covers accounts, devices, albums, push, and slideshows, with SDKs, samples, and Skill / MCP hooks. Partners keep their own app and brand experience; InkJoy runs the platform underneath.
Modular licensing
Need devices and the full platform? Choose Level 1. Have hardware but need device software and cloud? Choose Level 2. Have hardware and firmware but need cloud content services? Choose Level 3. Only need better image quality? Choose Level 4.
Cloud Platform
IoT Communication Protocol
Fastest launch: InkJoy provides hardware, Device RTOS, cloud / IoT, ISFR, and Merchant API; the partner owns the branded app and business service.

ISFR
Spectra 6 has a limited set of colors. Basic dithering can make shadows too dark or skin tones flat. ISFR first reads the image, then handles enhancement, color, and dithering together.
New models can be deployed in the cloud without upgrading devices, keeping output consistent as quality improves.
Optimize for small displays, ink-wash art, gift still life, or other visuals that matter to your brand.
Image understanding, enhancement, color management, and Spectra-aware dithering work together in one pipeline.
Partner cases
One case uses the full platform to launch quickly. The other adds only ISFR for image quality. Client names omitted under NDA.
Level 1 · Full Platform
The partner already had AIGC content capabilities. By connecting through Merchant API and our SDK, they built a test version in just two weeks and quickly launched a vertical ePaper frame, avoiding an estimated multi-million investment in app, cloud, and device R&D.
Level 4 · ISFR Service
A professional imaging company (under NDA) spent months tuning in-house but still could not meet its production quality bar. After adopting ISFR, the product entered mass production. ISFR now runs on more than 200K devices worldwide.
