According to DIGITIMES Research analyst Huang Yazhi, although Qualcomm, Qijing, and Truly cooperated in the launch of the 3D sensing module is currently the most mature 3D sensing solution, it is limited to the use of the Xiaolong 845 chip, the top five mobile phones in the Android camp. In the factory, only Xiaomi planned to deploy in high-end models. Samsung and Huawei are reluctant to use only high-end chips for high-end models, and they want to develop their own 3D algorithms. Therefore, they will not be the first to launch 3D in the Android camp. Face recognition mobile phone manufacturers. In order to match their own artificial intelligence chips or computing acceleration unit and self-control algorithms, it is not expected that Samsung will launch mobile phones equipped with 3D sensing modules until 2019; Huawei has requested internal laboratories, SI and the third-party industry developed algorithms and related hardware and software separately. However, at the end of last year, only external sensor modules that were not sold to the general consumer were introduced, which highlighted the dilemma that the sensor module could not be integrated into mobile phones at the time. The P20 launched at the end of March is also not equipped with a 3D sensing module. Xiaomi originally planned to launch the first half of this year to launch a Xiaolong 845 equipped with a 3D face recognition function. Terminal models are generally considered to be Xiaomi 7, but due to the backwardness of Qualcomm's software adaptation process, the success rate of facial recognition is low. It is expected that millet models with 3D face recognition will be delayed until the third quarter.
