Starting from the second half of last year, smartphones have basically entered the era of full screen, followed by a wide range of full screen mobile phones. Of course, the product has a contrast, there are naturally high and low points.
For domestic full screen mobile phones, I believe most mobile phone users have such experience, more or earlier 16: 9 screen 'elongated', and then there is now the promotion of 18: 9 size ratio. This is Second, the most important thing is the screen has not really reached the so-called full screen, after all, there is room for foreigners, relatively speaking, on the iPhone X came out, this embarrassing situation has been slightly eased, but there is such a change because of the iPhone X uses 3D facial recognition technology to completely 'discard' the traditional Home key and Touch ID ... not only for its tenth anniversary has a very memorable (even if the sales are now cold, it is also based on overpriced , And its design and appreciation can be discussed in isolation), it is now the direction of the development of the entire smart phone to play a guiding role.
In the face of the phone ring wind vane Apple this action, the domestic mobile phone is not far behind .Personal hold screen full screen visual effects but also have a breakthrough, it is indeed difficult.It is necessary to know almost all of the current domestic full screen mobile phone Have up and down the chin or chin, and then compromise the fingerprinting transfer to the backplane or side of the border above.However, in this piece to say a breakthrough, the biggest change is January 25 officially released vivo X20Plus screen fingerprint version of the full screen mobile phone Perhaps there is still room for up and down the amount of money (in fact the entire screen effect has been very good), but at least took the lead in the application of the fingerprint under the screen unlock.
Technically, vivo X20Plus using photoelectric emission technology, and specifically adapted OLED screen RGB Pixel emit light through the 0.68 mm thickness of the glass cover reaches the fingers, finger lines due to the different reflected light reflection, these reflected light and then Penetrate the screen, reach the fingerprint Sensor, in order to achieve fingerprint recognition.On the current use of view, it can be comparable to the traditional fingerprint scheme, support for unlocking, also supports mobile payment.You know, the traditional fingerprint recognition technology is generally capacitive touch sensing Recognition, such as FPC and HTC touch technology that recognition, so there is a huge leap between the two, of course, the product costs will naturally change accordingly also increased.
In the experience, vivo X20Plus compared to the traditional fingerprint solution in recognition speed can be a little slower, time is about a few tenths of a second gap, it can be understood as the need to light fingerprint recognition of all the circuit board texture; full screen state Under the screen is unable to support the unlock; part of the interest-screen state, that is, below the screen there is a bright fingerprint texture appears, you can screen unlock; wet hand state, the same support unlock; beyond the fingerprint texture half a finger above Unable to unlock screen, you can within.
This time we see the Apple iPhone X price more than eight thousand started, and only supports the facial recognition technology flagship phone.In Apple iPhone X, the reason is bangs shaped cutting full screen, in the final analysis bangs buried ' Multiple sensor elements, such as infrared lenses, pan-sensing elements, distance sensors, ambient light sensors, dot matrix projectors, etc., have so-called unique face ID generation.
So, what is the technology of the Apple iPhone X. In fact, it is through the dot-matrix projector, will be more than 30,000 naked invisible spot projection on the face, and then through the infrared lens to read the unique point Face array pattern, then the captured infrared image data back to the chip, so as to achieve the matching verification. Of course, if the dark environment, with the pan-infrared sensor invisible infrared light, the same facial recognition can be done.
So in this contest contend the market, under the screen fingerprint recognition and facial recognition which will get the maximum range of applications and promotion? If only just the phone circle, Xiao Bian personally think this year's new cell phone products or traditional fingerprint recognition and facial Recognition technology-based, domestic mobile phone bias will be biased in favor of the traditional 2D + 2D facial recognition, Apple mobile phone is the 3D face ID, as the so-called screen fingerprinting if the mass production shipments, then actually not possible X20Plus on sale situation, mainly to buy limited edition, that shows a substantial increase in costs while capacity is greatly affected), in the process of adaptation to accept the user have to consider the consequent price increases, so this piece The market growth to be accumulated · In addition, the field of facial recognition applications in real life examples will be more.
Currently, like the previous unmanned supermarkets, or the second half of last year formally entered the public life of the high-speed rail station automatic identification of facial recognition, the actual state of the new sprout is a start, showing that to some extent allow the public to quickly accept, And more widely used, the audience is more diffused facial recognition will be more and more popular.So, although the rise of facial recognition compared to mature traditional fingerprint recognition is slightly disadvantaged, there is always a process of growth, but I believe this process can be greatly reduced the transition time can be greatly reduced, then believe that facial recognition brings mass life (and work) more efficient feedback, which is the facial recognition charm.
In addition, from this year's Apple iPhone X is expected to release new news (exposure), it should not be unlocked with the fingerprint on the screen, and 3D facial recognition will be more optimized.It is understood that the Apple iPhone X will have three major this year Update, respectively, are regular updates, using LCD screen program updates and Plus version updates, of which the second update is obviously lower prices, after all, spend on the LCD screen, rather than OLED, estimated price will be six thousand Yuan or so.
