With the imminent arrival of CES 2018, many electronic technology enthusiasts have begun to look forward to new products at this year's show. Among them, the high hopes of consumers last year, but failed to achieve mass production of screen fingerprint phone, or will usher in the outbreak .
After the birth of a full screen mobile phone, manufacturers in order to narrow the chin as much as possible, have canceled the fingerprint recognition function, in turn using face recognition technology, such as the Apple iPhone X, Samsung S8, Samsung Note 8, vivo X20 / X20Plus , Plus a 5T, glory V10, Huawei nova 2, Nuts Pro, although face recognition looks both trendy and cool, but it is not the perfect solution, but there are also many problems.
Face ID Face Recognition Technology for iPhone X
Face recognition problems and more
Face recognition, on the other hand, also takes up the area of the front screen, like the front fingerprint, on the one hand, and the front bangs on the iPhone X. Also for face recognition, the technology is less mature, twins or longer can unlock, and security Not only that, when unlocking through face recognition, the user also needs to be facing the phone, and there is far no fingerprint on the posture.
In particular, iPhone X outside of the Android phone, equipped with face recognition are generally used to obtain facial recognition to achieve the realization of the face to unlock information, many users ridiculed as toys, and even take some photos of the owner can To unlock.
In fact, the full screen is not the precursor of the forerunner, face recognition is not a full screen lover, there is a technology that can perfectly solve the problem of chin size and forefinger, that is, under the fingerprint unlock.
Fingerprint recognition under the screen
But why many manufacturers this year, only facial recognition instead of using a full screen, instead of using the screen to unlock the fingerprint it? The reason, or because the screen is a very difficult fingerprint technology.
What is the fingerprint technology?
First of all, let's understand what exactly is the fingerprint technology under the screen.
As the name implies, the fingerprint on the screen is to place the fingerprint recognition module below the screen, and use the more penetrating optical and ultrasonic solutions to collect the rich pattern data on the surface of the finger and encrypt and store it in an independent safe area.
Although a high technology content, but there are already many fingerprint manufacturers developed this solution.For example, last year's World Mobile Congress held in Barcelona, Spain, the exchange of science and technology to demonstrate the screen fingerprinting technology, which is based on the The optical solution, which uses an optical fingerprint sensor placed under the screen, emits invisible structured light to be fingerprinted on the screen, but it is not yet commercially available.
Qualcomm, which specializes in the design of communications baseband and processors, is more interested in ultrasound solutions. In the middle of last year, Vivo demonstrated the prototype of a screen-based fingerprint recognition prototype based on Qualcomm's ultrasonic solution, the Xplay 6 model, but with one The problem is the recognition rate is low, a slight change in the finger under the pressure point of view there will be a case of unsuccessful unlock, this product is certainly not be used commercially.
Prototype display screen fingerprint technology
In addition to the top and Qualcomm, fingerprint recognition of the big brother of Sweden FPC company and the United States Synaptics Synopsys (now renamed the Chinese name of the new sudden thinking, quite a mouthful) of course, not idle.
The direction of the FPC is both optical and ultrasonic, but at present it is only in an unofficial commercial state, which may be that the yield is too low, the cost is high, and the recognition accuracy is also less than expected.
Synaptics had previously been a Samsung fingerprint sensor supplier, but later this company is not back down, in the domestic market share has not yet made domestically high technology.
On December 14, Synaptics released the ClearIDFS9500 fingerprint sensor family, which is known as a fingerprint recognition device that uses optical technology to illuminate the screen and reflect it on the screen Fingerprint identification, according to reliable sources at present this sensor has achieved mass production, new thinking of old friends Samsung S9 is likely to use this program.
Overall, this year's full-screen mobile phones are unable to use the fingerprint technology on the screen, in the final analysis, the technical level was not reached at that time, not low yield, high cost, that is, the recognition rate is not satisfactory, the user experience is not good.
Under the fingerprints are about to burst the future a variety of biometric identification or into the mainstream
From the current situation, under the screen fingerprints not far from full commercial.According to the author of the old iron supply chain revealed that this year (that is, in 2018, just switched over is not quite used) is likely to be fingerprinting under the screen year.
According to the latest news, the next to the debut of Samsung Galaxy S9, millet 7, LG G7, vivo Xplay 7 and many other new machines are expected to carry screen fingerprint recognition technology, and from the current news, these have underscreen fingerprint recognition Technology new machine, including a number of models will be held January 9 CES release.
However, after the fingerprint does not mean that face recognition will be abandoned, in fact, whether it is fingerprint recognition or facial recognition, iris recognition, they each have their own advantages and disadvantages.
Such as fingerprints with gloves can not be used, there is oil on your fingers or used for a long time will not be easy to identify the situation, the face recognition when wearing a mask unrecognized iris recognition If your eyes are sick or with sunglasses Only stare ...
Therefore, I believe that fingerprint identification, iris recognition, face recognition and other biometric identification of a combination of mobile phone unlocking program is the best strategy, and from the current development trend, a variety of mixed identification is very promising Become the mainstream in the future, let's wait and see!
