Pattern recognition is not a new technology. As early as 2011, MOTO Atrix 4G already has fingerprint recognition and unlock function. However, due to the limitations of technology at the time, the success rate of fingerprint recognition is not satisfactory. In 2013, Apple added on iPhone 5S. Touch ID fingerprint recognition function, with the addition of technology and fingerprint recognition functions, other manufacturers also added fingerprint recognition function to mobile phones. Are these fingerprint recognition functions really useful? What is the difference between positive recognition and behind recognition? Let's talk about these issues.
Common fingerprint identification solutions in the mobile phone industry
My colleague used to be "fingerprint recognition comparable to Apple?" The Meizu MX4 Pro in-depth evaluation article has compiled a common question and answer identification solution for the mobile phone industry at this stage. The author has perfected it on the basis of it.
From the table, we can find that the most important unlocking methods are front pressing, back pressing, front sliding, back sliding and back pressing. These methods will be tested in detail later. First of all, I will talk to you about these fingerprint identification providers.
First, AuthenTec (United States)
Introduction: AuthenTec is the world's leading provider of fingerprint authentication sensors and solutions for the PC, wireless devices and access control markets. On July 27, 2012, Apple acquired the company for $356 million. Since then AuthenTec belongs to Apple.
The fingerprint recognition sensor developed by the company is based on a capacitor and a radio frequency semiconductor. The sensor is combined with the Home button of the iPhone and iPad, and the uppermost layer is a sapphire cover. The sensor is completed by TSMC, and Taiwan Fine Materials and Crystal Technology complete wafer-level packaging. ASE is responsible for subsequent packaging and testing and SiP module production.
Object-Oriented: Apple's mobile phones and tablet products do not provide any products and technologies to the same industry vendors, but can provide for bank security and management services (I feel like paving the way for Apple Pay).
Second, Synaptic SynapTIcs Validity (United States)
Introduction: SynapTIcs is the world's leading designer and manufacturer of interactive interfaces for human-machine interface development in mobile computing, communications and entertainment devices. It was founded in 1986 and is headquartered in the United States. On October 17, 2013, it acquired the bio ID company Validity for $255 million and officially entered the field of fingerprint identification.
Object-Oriented: The Samsung Galaxy S5 and the HTC One Max released last year are all designed with SynapTIcs, but the difference is that the S5 is combined with the front and the Home button, while the HTC One Max is placed on the back cover. The solution, although the location of the fingerprint recognition is different, but the solution is the same.
Third, Fingerprint Cards AB (FPC)
Introduction: FPC develops, manufactures and markets biometric components and technologies to help identify users by analyzing and comparing their unique fingerprints. Headquartered in Gothenburg, Sweden, and listed on NASDAQ. It launched the world's first capacitive touch fingerprint sensor, the FPC1020, which uses an Android smartphone and tablet.
Object-Oriented: There are many objects for it. Everyone is familiar with vivo Xplay 3S, Huawei Mate7 and OPPO N3. Both of them put the sensor on the back, but the unlocking method is slightly different.
Fourth, Goodix Huiding Technology (China)
Introduction: Huiding Technology was established in 2002 and began to enter the touch industry in 2006. Based on the world's leading human-computer interaction technology research and chip design, Huiding Technology is now the sole strategic partner of MTK, with rich experience in mass production of capacitive touch chips and complete touch test system and test standards. Has more than 30 patents for capacitive touch technology.
Object-oriented: At present, only the Meizu MX4 Pro in the mobile phone market is the first mobile fingerprinting solution for domestic mobile phone manufacturers. I am proud of this. It is really hard for domestic technology companies to do this.

The Piezoelectric Ceramic sound-generating element, especially a lead-free piezoelectric ceramic sound-generating element, is mainly composed of metal flakes and piezoelectric ceramic flakes. The sound pressure generated by this new structure piezoelectric sounder is proportional to the number of piezoelectric ceramic sheets. By increasing the number of piezoelectric ceramic sheets, the required large sound pressure is easily achieved.
