Fingerprint identification and sapphire shades of fate

The 2013 launch of the Apple generation flagship product iPhone5S, to bring people in addition to the topic of unprecedented champagne (Tyrant gold) color, and its trend-setting mobile fingerprint recognition. 2014 follow-up Samsung Glaxay S5, Huawei Mate7, vivo Xplay3S, OPPO N3, Meizu MX4 Pro, Jin Tian Kam T1 and the next generation of Apple's flagship iPhone6, iPhone6 plus, all you can think of, the recent launch of the high-end machines, the flagship machine possess fingerprint recognition. Fingerprint recognition mobile phone is no longer with or without a problem, "China cool together" relevant person in charge of all publicly stated that in the near future, in 2015 one of the development of mobile phones undoubtedly determine the fingerprint.

Fingerprint sapphire so why manufacturers developed a taste, in addition to its luxurious atmosphere, whether there are other Sentimentality?

A typical fingerprint identification systems include: Fingerprint Sensor + feature extraction / matching module + feature template library + applications. And a matching fingerprint can be divided into two steps, first to be authenticated extracted fingerprint features, then the fingerprint and the template fingerprint template library similarity compared to determine whether the two fingerprint images from the same finger. You can say that the core of the fingerprint identification is accurate and efficient fingerprint analysis.

Application of fingerprint recognition sensor cover materials are: ceramics, sapphire and resins. The relatively soft resin material; ceramic dielectric and sapphire pretty, and relatively low cost, but its color is not controllable, if the color disposable meet the requirements, then the ceramic material can only be set aside.

Fingerprint recognition mobile phone since launch, on the relationship between the sapphire deal, which is due as a cover on the fingerprint sensor, sapphire has its unique advantages.

Sapphire advantages as fingerprinting cover

Sapphire as fingerprint recognition sensor on the cover, there are three major advantages:

First, read the fingerprint data, requiring very fast induction, sapphire relatively high dielectric constant, good thermal conductivity, can quickly react;

Secondly, since the fingerprint identification system is very sensitive fingerprint recognition sensor cover only a thin one, if the recognition area is scratched, it may cause not recognize, so the requirements cover material strength is very high. Sapphire hardness of 9H, scratch resistance, physical sector in few other substances can damage it.

Again, fingerprint recognition using a sapphire on the front panel to do the cover style, identification zone with the same mobile phone cover glass is clear and transparent mirror, making the phone look more beautiful and harmonious whole.

Indeed, the current cost of the use of sapphire is 4-5 times that of ordinary glass, large-scale use and supply chain maturity is the key to reducing costs.

"Sapphire large number of applications in the smart phone panel is only a matter of time," a new source of optical Industrial (Shenzhen) Co., Ltd. (hereinafter referred to as "new source of optics"), Chairman Liang said in an interview marked the current fingerprint identification area is just a round or elliptical thumb-sized area, the future may lower end of the entire panel is fingerprint recognition sensor area; new source of optics in terms of capacity utilization there is a huge room for improvement, ready to attack the mobile phone market.

Providing 70% of the Meizu MX4 Pro Sapphire

As the world's first fingerprint recognition front push Android phones, Meizu MX4 Pro around fingerprinting create "mTouch" system, fingers just gently press the Home key, the sensor will respond quickly under the sapphire, the whole process is only 0.5 seconds . Liang Standard in an interview that the sapphire cover Meizu MX4 Pro fingerprint recognition sensor, 70% come from a new source optics.

The new optical source was founded in 1994, has focused on sapphire lens, sapphire crystal, sapphire phone mirror, LED sapphire substrate and POS equipment protection lens production and processing. Currently, a new source of high-end watches optics provide domestic market 80% of the glass panel, FIYTA, according to Bo, Rossini and other domestic well-known watch brands are a new source of buyers; in foreign markets, new sources of optical main competitors are Japanese and Swiss firms, but also occupy a certain market.

A new source of long-term work in the optical field of watch components, but also has been closely observing the situation using a sapphire in the mobile space. The new optical source from 2012 to intervene phones, Nokia's luxury VERTU series sapphire cover indirect supply, now with the Department of the top technology cooperation, there Meizu mobile terminal client, Jin and other domestic terminal brand manufacturers.
