The white paper points out that the current car screen industry is facing user pain points such as limited size, small frame size, eye injury when viewed at close range, and motion sickness when driving, as well as insufficient layout of cutting-edge innovative technologies. As a new solution for in car display, the in car light field screen adopts unique spatial optical technology, breaking through the limitations of physical space inside the car, and achieving the effect of displaying a super large frame of 35 inches or more at a distance of about 3 meters from the human eye.

From the perspective of automakers, in car screen products have become the focus of differentiated competition among car companies. In terms of entertainment software, in car light field screens have a high degree of integration and good experience, and have the opportunity to become a new traffic entry point for intelligent cabins in the future. Finally, the white paper provides development suggestions from three levels: policy planning, standard regulations, and industry applications.
