From infrared face recognition to 3D face recognition, face recognition has become a standard for smartphones, and Apple has already begun to deploy in this area. According to foreign media reports, as early as February 2017, Seven months before Apple introduced the iPhone X, analyst Guo Mingxi said that the front camera that was exposed to the iPhone 8 would be a 'revolutionary' thing.

In fact, this technology does help Promoting the development of Face ID. Apple believes that the TrueDepth camera is quite successful, so the Face ID is used on the three flagship iPhones released in 2018 instead of Touch ID.
According to industry estimates, the success of Apple's use of VCSEL (Vertical Cavity Surface Emitting Laser) 3D scanning technology will greatly increase the demand for components used to manufacture these modules. This is the first company to produce such components from next year. It is a good sign, because suppliers of these components expect the Android phone manufacturers in 2019 and 2020 to use Face ID technology.
