The trend of automobile intelligence is becoming increasingly fierce, and functions such as Automatic Speech Recognition (ASR), gesture interaction, network connection, driver monitor system (DMS), etc. Greatly improve the requirements of chips’ quality and performance in automobiles. Regarding automotive applications, VCSEL and IR product projects can achieve infrared rectangular light to form a wide angle of vision and reduce loss by providing driver and passenger behavior monitoring, gesture interaction,and multiple . However,those projects can be used in Mini LED screens, ultraviolet lamp disinfection, outside car short-range radar,3D, etc.
