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 so-called mini projector is also called pico projector, TRT-Lcos Portable Projector. Mainly through the 3M LCOS RGB three-color projector and 720P film decoding technology, the traditional huge projector is refined, portable, miniaturized, entertaining and practical, making the projection technology closer to life and entertainment.
Usually the projector has certain regulations on 2 aspects:
a). Size: Usually the size is the size of a mobile phone.
b). Battery life: It is required to have at least 1-2 hours or more of battery life when it is not connected to power.
In addition, its general weight will not exceed 0.2Kg, and some do not even need fan cooling or ultra-small silent fan cooling. It can be carried with you (it can be put into your pocket), and the screen can be projected to 40-50 inches or more.
Advantage:
1. Completely replace the MP5 player, video, listening to songs, playing games, e-books, picture browsing, etc. MP5 video is affected by physical performance, the screen can not be bigger, and the screen of this thing is at least 20 inches.
2. Instead of the TV function, the machine can have a built-in CMMB function, or it can be directly connected to the set-top box to play the TV, and it can be used as a 21-inch TV during the day.
Look, it can be used as a 60-100-inch TV at night to achieve the effect of home theater; it is convenient to move and break through the traditional film and television space. Even if you are on the mountain, you can also share today's TV series, movies, and MTV with your lover.
3. Business office: instead of large projectors, it is used for company meetings; the price of large projectors is 4,000 to 14,000, and the lamp life is more than 1,000 hours, which is not convenient to carry. 30,000 hours, no need to change the bulb for 3 years, easy to carry, the salesman only needs to bring a micro projector to demonstrate the new product, which can achieve the demonstration effect.
4. Teaching: training meetings, classroom teaching; traditional projectors are not easy to carry. In school classrooms, due to the naughty students, projectors are not safe to place in the classroom and are easily damaged by students. The portability of micro projectors makes up for the teaching vacancies. In the future, teachers only need to store the materials in the projector and show them to students for teaching, saving the trouble of textbooks and handwriting with pens and chalks.
In addition, the micro-projection has no radiation, which can fully protect pregnant women and people with myopia. Its low power consumption function is 1/1,000,000 of the power consumption of color TVs. One day of electricity has completely impacted the indicators of safety, environmental protection, health, etc., and has made amazing contributions to future social development, standing at the peak of the green world as a leader.
