Why this product
A clear nameplate that is easier to reuse
Low-power E-Ink
A paper-like display keeps names, roles and meeting information visible between updates.
Indoor PV integration
A photovoltaic module can help harvest available room light. Actual contribution depends on lighting, update activity and the chosen system.
Reusable presentation
Change the displayed information for different people or events instead of printing a new paper card each time.
Use cases
Applications
Boardroom Meetings
Display directors' names and roles at each seat, then update the information when the meeting roster changes.
Conferences & Summits
Identify speakers, panelists and delegates across sessions without printing a new name card for every change.
Council & Committee Meetings
Show member names, titles or represented organizations at assigned seats for formal discussions.
Training Rooms & Workshops
Help instructors and participants learn names quickly, with displays that can be reused for new groups.
Panel Discussions
Present each panelist's name and affiliation to audiences and update the display between sessions.
Reception & Service Desks
Identify the person or service at a desk and keep information current as staff rotate.
Indoor PV in practice
From ambient light to a useful product
A nameplate is a concrete example of indoor solar product design. The photovoltaic module, power management, energy storage and e-paper display have to be matched to the light available where the device will be used.
Battery-free use or a specific charging interval cannot be assumed. For a reliable design, test the complete device under representative lighting and update patterns.

E-Ink display
Content and refresh needs.
From nameplate design to a display update
A successful desk nameplate brings together the display, indoor PV module, power system and content workflow.
Designed around the complete product
Form, screen viewing angle, PV placement and internal space are reviewed together. The enclosure and interfaces can then be assessed against the intended workplace and installation conditions.
- Display size and viewing arrangement
- Indoor light and PV placement
- Charging, storage and update interfaces
How content can reach the display
The diagram illustrates a template being prepared, transferred through a mobile workflow and shown on the E-Ink nameplate. Indoor PV and energy storage support the low-power device between updates.
Available software, cloud connectivity, BLE/NFC functions and the exact update method should be confirmed for the chosen model and project.

Please share your intended market, required configuration and estimated quantity. We can review the available options and provide a project-specific quotation.
Will it work without external charging?
That depends on lighting conditions, power consumption, energy storage and the selected configuration. We would need to assess the intended use case before estimating charging needs or operating time.
Can the product be customized?
You can discuss the display format, enclosure, branding, update workflow and solar integration with us. Customization options depend on technical feasibility and the scope of the project.
What is the minimum order quantity?
Minimum order quantities vary with the configuration, components and level of customization. Tell us your expected volume and project stage so we can discuss suitable options.
How long do samples and production take?
Lead times depend on design work, component availability, testing requirements and order volume. We can provide an estimated schedule after reviewing your specifications and confirming the project scope.
Is export to my market possible?
Please let us know the destination country and any documentation or compliance requirements. We can review the applicable product, shipping and regulatory considerations before confirming an export arrangement.
Can you support an OEM or ODM project?
Share your application, target specifications and any existing drawings or prototypes. We can discuss the engineering work, solar integration and manufacturing requirements involved; the development approach will depend on the project review.
