Apple still pick 3D to measure the beam? VCSEL production is not easy

In smart phones, 3D sensing is playing the role of "eye" in the professional field, and playing another role of opening a new mode of human-machine interaction.
In 2018, will the smart phone market trigger the upsurge of 3D sensing? From the new machine news that the relevant brand manufacturers are about to release, the wind of 3D has been opened, and "Liu Hai" has become a new word for many brand manufacturers to publicize.
"This year apple is still picking up the 3D beam."
Industry insiders say, Iphone X brings a wave of 3D sensing upsurge, and the key zero component VCSEL has become a new favorite in the market. However, because of the high technical threshold, the suppliers with the capacity of mass production are still quite limited, resulting in the problem of tight supply of VCSEL, which will affect the speed of follow-up of the Android camp.
Research institutions believe that in 2018, the penetration of global smart phone 3D will grow from 2.1% in 2017 to 13.1% in 2018, and Apple will still be the main adopter.
As for Apple's 3D speech, the agency has made relevant analysis. It has indicated that there are three technical thresholds for the production of 3D sensing module.
First, the high efficiency VCSEL component is not easy to produce, and the average current average photoelectric conversion efficiency is only about 30%. Secondly, the necessary component DOE of the structural light technology and the CIS of the infrared lens need very high technical details.
Thirdly, the production process of 3D sensor module should consider the problem of thermal expansion and cold contraction, and improve the difficulty of module assembly. These factors lead to the low production rate of 3D sensing module at this stage.
In addition, in order to cope with the market demand, although some manufacturers are actively expanding production, the overall yield of VCSEL is low and the market supply is insufficient. At present, the production of VCSEL is 6 inch wafer in accordance with economic benefits, but the production capacity of most manufacturers still stays at 3 inch or 4 inch, making the market overall supply and demand situation more tight.
At this stage, the market is most concerned about the Android camp, who will now follow the unusually hot cheers that carry the 3D sensing module, and probably the highest cheers will be the HUAWEI P20 released in late March of this year.
However, according to the relevant news, HUAWEI P20 will only carry the post 3D sensing module, the main function is to strengthen the AR function, not iPhone X face identification, based on this, the Android camp will first take a lower technical threshold of the ToF scheme.
In addition, according to the analysis of the industry, there is a patent agreement between Lumentum and apple, the main supplier of VCSEL, so that the Android camp will only take VCSEL and choose EEL (side fire laser) in the short term. However, the photoelectric conversion efficiency of EEL is poor and the cost is high, which will make the Android camp's 3D sensing scheme in efficiency and cost It's still hard to match the apple.
In fact, earlier, I learned from the supply chain that in all the zero components of the 3D camera launch module, the mainland manufacturers basically need to import, the most obvious in the VCSEL chip, the DOE diffraction element and the lens division. At present, the domestic manufacturers have the layout in these three major fields, but the fastest can be produced by the VCSEL core. The other two products are basically not manufactured by domestic manufacturers. So fundamentally speaking, the weak supply chain of 3D sensing is the main reason that affects the speed of Android camp's follow up.
Related personnel said, from the terminal market, the conservative estimate in 2018 can only be followed by only two Android manufacturers, including HUAWEI and millet with high voice, only the production number will not be too much. There was a message that the OPPO R15 dream version was also carried by the 3D test, but from the production experience and market, supply chain. Apple will still be the biggest adopter of mobile 3D sensing.
IPhone will change face in 2019
Since the iPhone X 3D sensing, the outside of the voice of the voice of the 3D sense of growing, earlier frequent news has burst, this year, iPhone three new machines will carry 3D sense of the news, even the new Apple iPad will use the front 3D sensing, for a moment, 3D sensing such as the upsurge to the entire mobile industry.
As we rush to the mobile phone industry, what is the trend of apple in 2019?
Recently, according to a new report from South Korea, according to a new report from South Korea, Apple will cancel the current iPhone X screen in the current iPhone X screen in the new OLED screen of the new iPhone screen. It is reported that apple is developing a brand new design that enables the front of iPhone to be completely covered by the display screen.
However, according to the news, the report did not reveal the details of how Apple handles the internal components of the groove. Then what components are inside the apple, the author inquires that in the groove of the iPhone X, it includes the front camera, the Face ID and the True Depth sensor, the dot matrix projector, the ambient light sensor, the speaker, the receiver and the distance sensor.
The media said Apple is currently in contact with several suppliers, and has discussed this idea technically.
An industry supply chain representative said Apple decided to abandon the grooves screen design from iPhone in 2019 and was in contact with related companies, and apple seemed to plan to achieve a truly comprehensive screen design on the iPhone.

One thing is for sure, Apple will retain Face ID face recognition technology, and speculate on the way of embedding components into the screen.
Some display technology insiders believe that apple can either punch holes on the OLED screen or use black background area technology on some screen areas.
So if the above is mentioned above, will the camera hide under the screen, will it affect the camera? Li Xing, an industry renowned analyst, has also given his opinion that, if only the Face ID module is hidden below the screen, this difficulty is similar to the difficulty of the current optical screen, and the function of face modeling can be realized.
But if you want to hide the self timer after hiding, this design will bring a great challenge to the whole camera light, because there is no light transmission over 50% of the display. If the camera is hidden only for face modeling, it can be realized, but if hidden, it can be hidden. After the formation of self timer technology, the final result may be a loss.
Although the accuracy of the foreign media is still to be measured, at least one point can be determined that the final purpose of the apple is to give up the design of the Qi Liu's groove. Can Apple achieve the overall screen target in 2019 after two generations of products? Maybe we'll have a question mark, too.
