FAQs
Q1: What is an E-paper display tag?
A: An E-paper display tag is an electronic label using e-ink (electronic paper) technology — the same display type used in e-readers. It consumes power only when the image changes and holds the displayed content with zero power draw afterward, giving it a paper-like, ultra-low-power display.
Q2: Does an E-paper display tag need a battery?
A: The NFC version does not — it is fully battery-free. A Bluetooth-powered version is also available for applications requiring remote, contact-free updates, which uses an internal battery.
Q3: How does a battery-free NFC E-paper display work?
A: The tag has no battery. It draws power from an NFC-enabled smartphone or reader during a tap, using that energy to refresh the e-paper display. Once the new image is set, the screen retains it with no power required — even after the phone is removed.
Q4: Which version should we choose — NFC or Bluetooth?
A:
Q5: Is the screen only available in black and white?
A: The standard model uses a high-contrast black and white (monochrome) display. Three-color versions (such as black/white/red) are available as custom options.
Q6: How many times can the screen be refreshed?
A: Under normal usage, the e-paper screen supports over 1 million refresh cycles.
Q7: Are your E-paper display tags waterproof?
A: Standard units have an IP rating suitable for everyday indoor and light outdoor use. For higher protection or fully sealed environments, we offer custom enclosure options. Please contact us with your specific requirements.
Q8: What industries use E-ink display tags?
A: Common applications include:
Q9: What sizes are available?
A: Standard sizes: 1.54 inch, 2.13 inch, 2.9 inch, 3.7 inch, 4.2 inch, and 7.5 inch. Custom sizes are available for larger orders.
Q10: Can you develop custom hardware for our application?
A: Yes. For B2B and system integrator projects with specific requirements, we offer full custom hardware development, including PCB design, enclosure, and firmware.
Q11: Do you provide SDK or API for system integration?
A: Yes, we provide SDK and API support for seamless system integration.
Q12: Can I customize what's shown on the display?
A: Absolutely. You can display QR codes, logos, barcodes, product names, flight information, employee details, and other data fields tailored to your application.
