Abstract
A heads-up display for a vehicle is in contrast to the windshield behind the display or the environment outside of the vehicle windshield. In this way, the heads-up display is more visible than prior art heads-up displays. In one embodiment, the windshield is tinted to be in contrast with the color of the heads-up display, at least over a small area. In other embodiments, the image forward of the vehicle is captured and sent to a control for the heads-up display. The heads-up display is then modified to be in contrast with the environment approaching the vehicle. In another embodiment, the window is modified to have a back glow over a small area. The heads-up display is directed onto this small area.
