On the smart phone, 3D sensing plays the role of “human eye†in the professional field and plays another role in opening another new model of human-computer interaction. Let's take a look at the related content with the mobile phone portable Xiaobian.
Then, in 2018, will the smartphone market set off a wave of 3D sensing? From the news of the new brand that the relevant brand manufacturers are about to release, the wind of 3D sensing has already started, and “Liu Hai†has become a publicity of many brand manufacturers. New words.
"This year, Apple still picks 3D sensing beams."According to industry insiders, Iphone X has brought a wave of 3D sensing, and the key component VCSEL has become a new favorite in the market. However, due to the high technical threshold, the suppliers with mass production capacity are still quite limited, which leads to the problem of tight supply of VCSEL. In turn, it affects the follow-up speed of the Android camp.
Some research institutions believe that looking forward to 2018, the global smart phone 3D sensing penetration rate will grow from 2.1% in 2017 to 13.1% in 2018, and Apple will still be the main adopter.
For the remark that Apple still picks the 3D girders, the agency said that the current production of 3D sensing modules has three technical thresholds.
First, the production of high-efficiency VCSEL components is not easy. At present, the average current photoelectric conversion efficiency is only about 30%. Secondly, the DOE of the structural light technology and the CIS of the infrared lens require a very high technical foundation.
Third, the production process of the 3D sensing module needs to consider the problem of heat expansion and contraction, and improve the difficulty of module assembly. These factors have led to a low production yield of the current 3D sensing module.
In addition, in response to market demand, although some manufacturers actively expand production, VCSEL's overall yield is low, resulting in insufficient market supply. Currently, VCSEL mass production is more economical with 6-inch wafers, but most manufacturers still have a production capacity of 3 Inch or 4 inches, the overall supply and demand situation in the market is more tight.
At this stage, the market is most concerned about the Android camp. At present, the cheers of those who will follow up with the 3D sensing module are extremely hot. The highest cheering will be the Huawei P20 released at the end of March this year.
However, according to relevant news, the Huawei P20 will only be equipped with a rear 3D sensing module. The main application function is to enhance the AR function. It is not the face recognition of the iPhone X. Based on this, the Android camp will adopt the ToF solution with lower technical threshold.
In addition, according to industry analysts, VCSEL's main supplier Lumentum and Apple have a patent agreement, so that the Android camp wants to follow up in the short term can only choose VCEL and EEL (edge ​​laser), but EEL photoelectric conversion Poor efficiency and high cost will make the Android camp's 3D sensing solution still difficult to match Apple's efficiency and cost.
In fact, earlier I learned from the supply chain that among all the components of the 3D camera transmitter module, mainland manufacturers basically need to import, which is the most obvious in the field of VCSEL chip, DOE diffraction element and lens splitting. Currently in these three major Domestic manufacturers in the field have layouts, but the fastest mass production should be VCSEL chips. The other two products are basically not manufactured by manufacturers. So fundamentally, the weak foundation of the 3D sensing supply chain has become the main reason for the speed of the Android camp.
Relevant personnel said that from the perspective of the terminal market, it is conservatively estimated that in 2018, only two Android manufacturers may follow up, including Huawei and Xiaomi, which are also high-sounding, but the production volume will not be too much. The OPPO R15 Dream Edition is also equipped with 3D sensing, but from the mass production experience and market, supply chain, Apple will still be the biggest adopter of mobile 3D sensing.
Passing 2019, iphone will change faceSince the iphone X is equipped with 3D sensing, the voice of 3D sensing has grown stronger. Recently, there have been frequent news explosions. This year, three new iPhones will be equipped with 3D sensing information, even Apple’s new ipad will be adopted. Front 3D sensing, for a time, 3D sensing, such as the boom, flooded the entire mobile phone industry.
While flocking to the mobile phone industry, the outside world is also very concerned about Apple's every move. Then, what will happen to Apple in 2019?
A few days ago, according to foreign media reports, according to a new report from South Korea, Apple will cancel the current iphone X screen bangs groove design in the 2019 OLED screen new iphone. It is reported that Apple is developing a new design that allows the front of the iPhone to be completely covered by the display.
However, according to sources, the report did not reveal the details of how Apple handled the internal components of the groove. So what components are inside Apple, the author found that in the iphone X groove, including the front camera, Face ID and True Depth sensor, dot matrix projector, ambient light sensor, speaker, earpiece and distance sensor, etc. Component.
The media said that Apple is currently in contact with a number of suppliers to conduct technical discussions on this idea.
An industry supply chain representative said that Apple decided to abandon the groove screen design from the iPhone in 2019 and is in contact with related companies. Apple seems to plan to achieve a true full screen design on the iPhone.
One thing to be sure is that Apple will retain Face ID facial recognition technology and speculate on the way to centrally embed components inside the screen.
Some display technology industry insiders believe that Apple either punctured the OLED screen or used black background area technology on some screen intervals.
So if you really say the above, hiding the camera under the screen will affect the camera? Li Xing, a well-known analyst in the industry, also gave his opinion. He said that if you just hide the Face ID module below the screen, This difficulty is similar to the difficulty of fingerprinting under the current optical screen, and the face modeling function is achievable.
However, if you want to form a self-timer mode after hiding, this design method will bring great challenges to the entire camera light, because there is no display product with a light transmittance of more than 50%, if you hide the camera only In order to realize the face modeling function, it is achievable, but if the self-timer technology is formed after hiding, the final result may not be worth the candle.
Although the accuracy of foreign media's news still needs to be considered, at least one can be sure that giving up Qi Liu's groove design is Apple's ultimate goal. Can Apple achieve the goal of full screen in 2019 after two generations of products? Maybe we have to put a question mark.
The above is about mobile phone portable - Apple still picks 3D sensing girders? VCSEL production is not easy to introduce, if you want to know more information, please pay attention to eeworld, eeworld electronic engineering will provide you with more complete, more detailed and updated information.
