The Future of Smart Payment Starts Behind the Display

Traditional NFC payment systems usually require users to tap their cards or mobile devices on a dedicated reader area located beside or below the display.

However, as smart terminals become thinner, more integrated, and more user-friendly, a new payment interaction technology is gaining popularity — Under-Display NFC Technology.

With an under-display NFC touch display solution, the NFC antenna is placed behind the display module. The user can simply tap a card, smartphone, or NFC device directly on the screen area to complete payment.

This creates a cleaner industrial design, improves user experience, and enables seamless integration for:

• Smart POS terminals
• Self-service kiosks
• Ticketing machines
• Access control systems
• Medical terminals
• Industrial HMI devices

For manufacturers developing next-generation smart devices, the challenge is not only integrating NFC — but selecting and customizing a display module that allows stable NFC performance.

What Is an Under-Display NFC Touch Display?

An under-display NFC touch display combines three key technologies:

1. Display Module

The TFT LCD provides visual information and user interaction.

2. Capacitive Touch Panel

The PCAP touch screen enables multi-touch operation and smooth user interaction.

3. NFC Antenna Integration

The NFC antenna is installed behind the display, allowing the screen surface to become the payment interaction area.

Typical structure:Unlike traditional NFC readers, the entire front surface becomes part of the interactive payment experience.

Why Is Display Selection Critical for Under-Display NFC?

Many customers assume that any LCD touch screen can support NFC behind the display.

However, this is not true.

The display structure directly affects NFC signal transmission.

The key factors include:

1. Backlight Structure Optimization

The biggest challenge is the backlight design.

The NFC antenna requires a specific transmission area behind the display.

If the backlight has:

• Uneven thickness
• Metal shielding interference
• Structural sagging
• Improper window design

the NFC signal strength may decrease significantly.

Therefore, the NFC window area must maintain:

✔ Flat backlight structure
✔ Stable optical performance
✔ Low electromagnetic interference

2. Metal Frame and EMI Interference Control

Industrial displays often include:

• Metal bezels
• Shielding layers
• FPC cables
• Conductive materials

These components may affect NFC performance.

During customization, engineers need to evaluate:

• Antenna position
• Metal distance
• EMI shielding design
• Grounding structure

3. NFC Recognition Distance Requirements

Different applications have different NFC requirements.

For example:

Standard Payment Application

NFC recognition distance:
Around 2 cm

High Performance Requirement

NFC recognition distance:
Around 4 cm or more

The longer the sensing distance, the higher the requirements for:

• Display material selection
• Backlight structure
• NFC antenna design
• EMC optimization

Why Standard Displays Usually Cannot Meet NFC Requirements?

A standard LCD module is designed mainly for:

• Display quality
• Brightness
• Viewing angle
• Power consumption

But an NFC integrated display requires additional consideration:

Therefore, professional engineering verification is necessary before mass production.
