Synaptics Announces World's First Downscreen Fingerprint Sensor fs9500
Since the beginning of this year, it has been reported that Samsung Note8 or Apple iPhone X will be equipped with on-screen fingerprint recognition technology. However, when the two new machines were released to the public, the fingerprints on the screen were missing. And, due to the dedicated full-screen design, Samsung Note8 fingerprint recognition is placed on the back of the phone, iPhone X is directly deprecated Touch ID. The lack of fingerprints under the screen has become a big regret for these two mobile phones. Recently, Synaptics announced the launch of the world's first off-screen fingerprint sensor, model Clear ID FS9500. According to reports, FS9500 is directly packaged in the AMOLED display module, using the same optical materials and processes as the standard OLED, the final thickness can be less than 1.5mm. In addition, the sensor uses optical technology to support localized TLC/AES/ECC encryption. Moreover, Synopsys International stressed that the FS9500 has been provided to a TOP5 mobile phone manufacturer and is in mass production. The related models will be displayed at CES in January 2018. According to reports, the Clear ID FS9500 fingerprint sensor family can achieve the same biometric authentication convenience without the need to press the circular identification button of the circular opening. With the help of this sensor embedded in the bottom of the screen, people can enjoy the "full screen". The Clear ID design is quite new and will initially be used with OLED displays. When activated, an FS9500 sensor uses the upper OLED panel backlight to illuminate the area of ​​the finger and then delivers the reflected fiber to the rear sensor. According to Synaptics, it acts as a “tired thing†that occupies at most 1.5 mm thickness; or it uses standard optical production materials and processes; it is integrated into the OLED panel. Of course, the perception of the presence of a finger is only one of the concerns of biometrics. Synaptics is committed to providing users with biometric information that is protected by the company's SentryPoint Security and Anti-Spoofing Suite technology. The FD9500 can adaptively improve the ability to identify user fingerprints, keep all replicas out of the box, and ensure the security and authenticity of information transfer from sensor to host with TLS, AES encryption, and ECC. Synaptics also pointed out that because the sensor is embedded under the screen, it is lower than moisture, abuse and dirt than open external buttons. Finally, although the company has not announced any design proposals today, it said it will have an in-house production demonstration process that is expected to appear on the first mobile phone released on CES 2018. What is the difficulty of fingerprint recognition technology under the screen? From the technical principle of fingerprint recognition, optical, capacitive, thermal and ultrasonic are four common methods of fingerprint recognition. On electronic devices such as mobile phones and tablets, compact and low-cost capacitive modules are the first choice of most consumer electronics manufacturers. Optical, capacitive, thermal and ultrasonic, four common fingerprint recognition technologies A capacitive sensor placed under the Home button or under the back of the fuselage captures the rich texture data on the finger surface and is encrypted and stored in a separate security zone. To enter a fingerprint completely, you usually need to paste it 8-12 times on the button. Today's capacitive fingerprint sensor recognition + unlock speed is very ideal, from the finger to the main screen only takes 0.15-0.2 seconds, almost no waiting time for daily use. In terms of safety, many capacitive fingerprint modules have integrated the in vivo detection function, which can sense the temperature change of the finger surface through a thermal sensor. The artificial fake finger or the cold broken finger is difficult to recognize. However, capacitive sensors also have disadvantages. It has no way to identify the fingerprints pressed on the screen through the screen of the mobile phone, mainly because the thickness of the screen module itself causes the sensor to collect insufficient useful signals. In this way, the fingerprint recognition under the screen can only be achieved by two optical and ultrasonic solutions with stronger penetrating power. 4Lan Software Router,4Lan Mini Pc,4Lan Firewall Router,4 Ethernet Mini Pc Shenzhen Wanheyun Computer Co.,Ltd. , https://www.xcypc.com
