Fingerprint recognition is no longer a new technology. Look at the current thousand yuan level has been standard fingerprint identification, even a few hundred dollars of low-end mobile phones are also configured, you know the popularity of this technology. This rapid development momentum has been more robust in 2016, but it also faces the problem that the placement of fingerprint recognition is more in line with user needs and accuracy. At the same time, under the influence of the upcoming Under-glass new technology solution, how will the mainstream technology of fingerprint identification schemes appear? To this end, "Huaqiang Electronics" recently invited representatives of enterprises and experts in the field of fingerprint identification to conduct in-depth discussions.
A variety of installation methods compete for market positive recognition
From the perspective of current smart phones, fingerprint recognition mainly has three installation methods: front, back and side. With the development of smart phones, what is the mainstream installation method? In order to reduce its cost and promote its application, how can the identification scheme further improve its performance while taking into account the cost advantage?
As we all know, the fingerprint recognition module is installed on the front side more in line with people's usage habits, and the operation is more convenient, but the design difficulty of the whole machine will be increased, the factors that need to be considered and taken into consideration will be more, and the appearance requirements are higher; The identification module is the easiest to implement on the back, the cost is the lowest, and the appearance requirements are relatively low. Therefore, it is adopted by mobile phone manufacturers such as Huawei, but the user's operating experience is worse than the front-end solution.
As for the side buttons, Huiding Technology told reporters in an interview with this magazine that the side program is not good because of poor technical performance, user experience is not good, and design difficulty is not small, so it will not become mainstream. Further from the development of smart phones, back fingerprint recognition has more difficulties in adapting to mobile phone plus jackets and compatible wireless charging solutions.
Guo Xiaochuan, general manager of Mindray Microsystems, also agreed. He said that based on the current state of technology development and user experience, side fingerprint identification will only exist as a differentiated solution in the future. It can be seen that the positive identification scheme and the back recognition scheme first allow more market space, and over time, the positive identification scheme will gain the largest market share in the smart phone field due to its good user experience, becoming the mainstream of fingerprint identification. Program. Not only that, but from the development of fingerprint recognition on smartphones, it can be seen that the trend of positive recognition schemes is becoming more and more obvious.
According to Guo Xiaochuan, the reporter said: "Maily Micro started mass production of TSV packaged fingerprint chips with front ceramic cover at the end of 2014. However, due to the hot sale and leading of Huawei MATE7, the leading manufacturer of smart phones in the domestic market, the market forces turned to the market. COATING fingerprint recognition on the back."
However, it is precisely because of this market shift that the terminal market has put forward a strong demand for the back-molded COATING product line for fingerprint module manufacturers. Therefore, the companies that are the first to push the fingerprint chip for the cover module have increased the number of companies that are the first to use the fingerprint module. The COATING product line is molded on the back.
However, the launch of OPPOR9 in 2016 began to lead the market again from the back COATING to the front cover. From this historical point of view, market demand has its own internal driving force, which is the result of industrial design needs, technology development, supply chain improvement and cost accounting. Faced with the complicated and volatile market situation, Guo Xiaochuan puts forward: "As an upstream chip supplier, it is necessary to do a good job in both hands, and both hands must be strong in order to meet the needs of mobile phone manufacturers to meet new demands."
At this point, Huiding Technology concluded that the mainstream direction of the future development of the fingerprint identification module will be based on the positive solution, while the low-end solution will adopt the back solution. He further puts forward: "From a longer-term perspective, the user experience is always the first, and there are more and more ways to reduce costs, so the application of positive solutions will become more and more extensive."
In summary, it can be seen that whether it is driven by the market or under various process conditions, the positive fingerprint identification scheme can quickly enter the market, meet market demand and bring good benefits to fingerprint module manufacturers, so the positive fingerprint identification scheme Will become the mainstream form of the market. However, since the market demand is not static, the back fingerprint identification will still occupy a certain market share in the future low-end smartphone market. Therefore, the fingerprint identification manufacturers only have two hands to grasp, and the two different process lines on the front and the back can be perfected in the competition situation. The field of white-hot smartphones has jumped out of the way to meet market demand and gain benefits.
