What Is In-Display Fingerprint Technology?

In-Display Fingerprint technology integrates a biometric sensor beneath the smartphone screen, allowing users to unlock their device or verify identity by simply touching the display. Unlike physical sensors located on the back or side of devices, In-Display Fingerprint sensors work invisibly, enhancing both design aesthetics and user experience.

The system reads the user’s fingerprint pattern through the OLED or AMOLED screen, analyzing ridge patterns, pressure, and light reflections to authenticate identity within milliseconds.

This innovation merges optical sensing, machine learning algorithms, and AI-driven pattern recognition, making fingerprint scanning more efficient and secure than ever before.

Core Features of In-Display Fingerprint 2.1.01

  1. Seamless Display Integration The fingerprint sensor is embedded directly into the display, eliminating the need for a separate physical button.

  2. Enhanced Security Algorithms Using advanced pattern recognition and encryption, it ensures data remains secure and tamper-proof.

  3. High-Speed Recognition With optimization in version 2.1.01, the authentication process is faster than traditional capacitive sensors.

  4. Power Efficiency The software intelligently activates the scanning area only when needed, conserving battery life.

  5. Customizable Experience Users can set personalized unlocking animations and adjust sensitivity settings.

How In-Display Fingerprint Works

In-Display Fingerprint technology uses a combination of optical and ultrasonic sensors to read fingerprint details through the screen. When a user places their finger on the designated area, the sensor captures a high-resolution image of the fingerprint.

  • Optical Systems: Illuminate the finger using the display’s light, capturing an image for analysis.
  • Ultrasonic Systems: Emit sound waves to map the ridges and valleys of a fingerprint with 3D precision.

The captured data is then processed by Goodix’s fingerprint recognition engine, verifying the identity against stored encrypted templates within the device’s secure enclave.

This process takes place almost instantaneously — typically within 0.2 seconds — ensuring both speed and accuracy without compromising security.

Advantages of In-Display Fingerprint Technology

| Feature | Advantage | | -------------------- | -------------------------------------------------------------------------- | | Aesthetic Design | Eliminates the need for physical buttons, allowing for bezel-less displays | | High Security | Protects biometric data using local encryption and on-device processing | | Ease of Use | Enables quick, one-touch authentication | | Durability | Reduces mechanical wear compared to traditional fingerprint sensors | | Compatibility | Works seamlessly with Android’s security frameworks and applications |

In-Display Fingerprint 2.1.01: What’s New

The 2.1.01 version introduces several performance and compatibility enhancements, particularly for newer Xiaomi and Android devices. Key improvements include:

  • Faster fingerprint registration process
  • Improved sensor calibration accuracy
  • Enhanced AI recognition to minimize false rejections
  • Better support for multi-language interfaces (46 total languages)
  • Optimized integration with Android 15 security frameworks

These updates make In-Display Fingerprint smoother, more secure, and more accessible across global device markets.

The Role of Goodix and Xiaomi

The In-Display Fingerprint technology in Xiaomi devices is powered by Goodix, a leading biometrics solutions provider. Xiaomi integrates Goodix’s cutting-edge fingerprint modules into its Android firmware, combining hardware and software for a frictionless user experience.

Goodix provides the underlying biometric SDK (Software Development Kit), while Xiaomi ensures seamless compatibility within its MIUI system. Together, they form a robust ecosystem that prioritizes privacy, speed, and security.

Security Aspects of In-Display Fingerprint

Security lies at the heart of In-Display Fingerprint technology. The system operates entirely within Android’s Trusted Execution Environment (TEE), meaning all fingerprint data is processed and stored locally on the device.

  • No Cloud Transmission: Fingerprint data never leaves the phone.
  • Encrypted Storage: Each fingerprint image is transformed into an encrypted digital template.
  • Anti-Spoofing Mechanisms: Detects fake fingerprints, photos, or silicone molds using pattern and depth analysis.

These measures ensure that In-Display Fingerprint remains one of the most secure authentication methods available in modern Android smartphones.

How In-Display Fingerprint Improves User Experience

The In-Display Fingerprint system elevates user experience through design and functionality:

  1. Faster Access: Unlocks devices instantly without pressing buttons.
  2. Enhanced Aesthetics: Maintains sleek, uninterrupted display designs.
  3. Multi-App Integration: Works with payment systems, password managers, and app locks.
  4. Accessibility: Functions effectively even with partial fingerprints or minor screen smudges.

These innovations make In-Display Fingerprint a perfect blend of usability, style, and reliability.
