What is the difference between capacitive, optical and ultrasonic fingerprints: understand in one article

Nowadays, fingerprint recognition technology has become an indispensable security feature of mobile phones. From the initial password input to sliding pattern unlocking to today's fingerprint recognition, the evolution of unlocking methods not only improves security, but also optimizes user experience. Currently, there are various fingerprint recognition technologies on the market, including ultra-thin under-screen fingerprint recognition, screen ultrasonic fingerprint, ultrasonic fingerprint unlocking, etc. These technologies sound high-end, but what’s the difference between them? Which one is the most practical? Let's talk together. Capacitive fingerprint recognition Capacitive fingerprint recognition technology collects fingerprints through two methods: scratching and pressing. Scratching technology is gradually being eliminated by the market due to its high operational requirements and low recognition speed and accuracy. The push-type capacitive fingerprint recognition technology allows users to complete the identification by simply pressing it. It is easy to operate and has become rapidly popular since it was first installed on iPhone 5s. Optical fingerprint recognition Optical fingerprint recognition technology uses the principle of light reflection to embed the sensor under the screen to achieve under-screen unlocking. This technology not only provides a sense of technology, but also improves the security and aesthetics of the phone. It is worth mentioning that optical fingerprint recognition can be divided into several different types, among which "short focus" and "ultra-thin" are the two main design concepts.

1. Ultra-thin fingerprint:

• The module is slim and placed in an ergonomic position, making unlocking natural and convenient.
• The placement of the short-focus fingerprint module is limited, which affects the convenience of one-handed operation.

2. Ultrasonic fingerprint recognition:

   • detects the finger surface through ultrasonic waves and constructs a 3D image for comparison.
   • Collect fingerprint three-dimensional information with high security.
   • Maintains high recognition rate in various environments and supports wet hand unlocking.
   • The unlocking position is reasonably designed, easy to operate with one hand, and there is no strong light stimulation in dark light environments.
   • Only installed on high-end flagship models.

3. iQOO Neo9S Pro+:

   • equipped with the only ultra-flagship ultrasonic 3D fingerprint technology in its class.
   • The sensor is located at the top and there is no light during recognition.
   • The advantages such as wet hand recognition are retained, and the user experience is far superior to products of the same level.

     

     Summary

1. Technological innovation:
iQOO Neo9S Pro+’s ultrasonic fingerprint recognition technology is an innovation of existing technology and breaks through the limitations of traditional fingerprint recognition.

2. User Insights:
This technology has a profound insight into users’ needs for security, privacy and convenient unlocking experience.

3. Improved security:
Ultrasonic fingerprint recognition technology enhances the security and privacy protection of mobile phones, ensuring the reliability of users’ personal information.

4. Convenient unlocking:
It brings a faster and more convenient unlocking experience to users in the mid-range market, improving the convenience of mobile phone use.
