3 Summary

The ultimate success of a DGP application depends on being clearly visible to the driver or pedestrian. Many different factors affect the apparent brightness of a dynamic ground projection display including projector brightness, ambient lighting conditions, and projection surface. Different requirements for image size and placement may cause different requirements for projector brightness, contrast, and overall form factor. Understanding the desired viewing conditions and display content is the first step to determining the remainder of the DGP brightness design.
