Three new changes of iPhone 8: cancel home key screen identification fingerprint

according to Taiwan media, TSMC revealed its close cooperation with apple for the first time in the Technology Forum on the 25th, announcing major functional changes of Apple's iPhone 8 new machine this year, including the cancellation of the home key, direct identification of fingerprints on the screen, the change of screen size from 16 to 9 to 18.5 to 9, and the improvement of high-pixel camera performance with invisible light, infrared and other image sensors, which will make the market amazing.

TSMC, which has never commented on the dynamics of Apple's customers, revealed the new trend of Apple's I8 mobile phone in public for the first time yesterday TSMC's supply chain said that in addition to announcing the exclusive application of TSMC in the new generation a11 processor of I8 for apple, TSMC's superior process technology, and its own OEM orders, TSMC also announced the close cooperation between the two to the world, which can create a win-win situation in the new machine sales.

Secondly, TSMC also takes advantage of the annual technical forum to give a heavy blow back to Samsung Electronics, which is going to accelerate the promotion of the independent establishment of a new company for wafer foundry in the near future. In addition to demonstrating that the global chip manufacturers support TSMC's four major technology platforms, it emphasizes that apple is unlikely to cooperate closely with its competitor, three star group.

TSMC said that after Samsung changed the screen size of the new mobile phone to 18.5-9, it would let the Android camp change the design in full, so that the new products that were to be launched in the second quarter would not be launched until July of the third quarter.

In addition, apple removed the home key and changed it to an optical fingerprint identification chip, which can directly complete fingerprint identification on the screen. At present, Samsung and other manufacturers are still unable to keep up.

Apple has also introduced invisible infrared image sensors into the new phones to improve the function of high-pixel cameras, which can be extended to more practical applications and enhance the attention of Apple's new phones.

TSMC emphasizes that in the future, artificial intelligence, AR, VR, etc. will drive the sustainable growth of semiconductor industry In addition to the R & D expenditure of up to $2.2 billion this year, TSMC has also invested up to $10 billion in capital expenditure, established advanced technology and abundant production capacity, and will assist customers to achieve the goal of "TTM" in the shortest time, including "time to maket" and "time to money".

However, according to other media reports:

There are different opinions about the location of the fingerprint unlocking of the legendary iPhone 8. Whether it is designed on the back or embedded in the display screen, various message channels give different opinions. Now, some netizens revealed on Weibo that the iPhone 8 will cancel the fingerprint unlocking function and use more powerful structured light 3D scanning technology to unlock the face with the help of two front cameras, but the authenticity of the message has yet to be confirmed.

Support 3D scanning technology

Previously, there was a rumor that the location of fingerprint identification of iPhone 8 would be embedded under the display screen, but later it came out that because the technical problems had not been solved, the post fingerprint unlocking design had to be used, and a group of spy photos of real machine models were also exposed on the network, which showed that there was indeed a circular fingerprint unlocking module under the back Apple logo, compared with the previously leaked SIP (standard inspection The chart is identical.

However, some sources said that the leaked model was actually a domestic copy, based on the early prototype of the iPhone 8. The real iPhone 8 will use 3D scanning technology, no iris recognition, and full screen fingerprint recognition, but also said that it is not completely sure of its authenticity.

To cancel fingerprint identification

It is worth mentioning that now another netizen has released a partial spy photo of the front panel of the iPhone 8 on Weibo, saying that the iPhone 8 is not a post fingerprint, nor a screen unlocking, but the fingerprint unlocking function has been cancelled. Instead, it's a 3D scanning technology, but it's not related to iris recognition. For this reason, many netizens speculated that Apple might use structured light 3D scanning technology to realize face recognition this time, combining the two holes in the spy photos on the front panel and the 3D scanning technology described.

From the current characteristics of structured light 3D scanning technology, two cameras will be used to provide stereoscopic vision technology, but the calculation requirements are very strict, and the environment lighting conditions are very sensitive, so special sensors are needed to assist. From the perspective of the previously exposed structure diagram of iPhone 8, it seems that such conditions are fully met. Specifically, the iPhone 8 has a 3D camera on the left side of the earpiece and infrared creatures on the right side

All black one second unlock

Although the authenticity of the above information remains to be confirmed, especially whether the iPhone 8 really cancels the fingerprint unlocking function is still full of suspense. But according to the source, the iPhone 8 with 3D scanning technology can unlock in one second in full black space, which may be related to the infrared biometric sensor.

In addition, there are rumors in the past that the iPhone 8 will be postponed to November, one of which is that there is still a problem with the new 3D component fitting the screen, so there are various signs that the future iPhone 8 may bring new technology in face recognition or unlocking. As for whether the delay is caused by the technical problems, it may not be more clear until this summer Statement.
