Under-Display NFC Payment Technology: How Touch Displays Enable Direct Card Payment on the Screen
Under-Display NFC Payment Technology: How Touch Displays Enable Direct Card Payment on the Screen
From Side Swiping to Screen Swiping — The Next Generation of Payment Experience
In traditional payment scenarios, users usually need to place their bank card, NFC card, or mobile device near a designated sensing area beside the terminal to complete the payment.
With the development of smart devices, a new interaction method is emerging — Under-Display NFC Technology.
With an under-display NFC solution, the NFC sensing area is hidden beneath the display. When making a payment, the screen can automatically display a payment interface, allowing users to simply place the card or NFC device directly on the screen area to complete the transaction.
This design not only improves the overall appearance and integration of the device but also creates a more intuitive and convenient payment experience.
What Requirements Does Under-Display NFC Place on Display Modules?
Although under-display NFC appears to be simply adding an NFC module behind the screen, it actually creates higher requirements for display design.
One of the most critical factors is the backlight structure of the display module.
Because the NFC antenna needs to be installed behind the display, the NFC sensing area requires:
- No obvious backlight sagging in the NFC window area
- Minimal impact on NFC signal transmission
- Proper window opening design in the display structure
- Evaluation of internal materials and electromagnetic interference
In other words, not every display can support under-display NFC applications.
The backlight design, metal frame, FPC routing, shielding materials, and internal structure may all affect NFC signal strength and card recognition distance.
Why Does Under-Display NFC Require Custom Validation?
During actual product development, different customers have different requirements for NFC sensing distance and application environments.
For example:
- Some customers require an NFC recognition distance of around 4 cm
- Some applications only require stable recognition within 2 cm
- Different sensing distances require different levels of electromagnetic interference control and display structure optimization
Therefore, an under-display NFC solution cannot simply use a standard display module.
A complete evaluation needs to consider:
✅ LCD size and mechanical structure
✅ Backlight design
✅ Metal frame influence
✅ NFC antenna position
✅ EMI/EMC interference performance
✅ Real-world payment solution testing
Only after system-level verification can the most suitable display solution be selected.
