The Head-up Display (HUD) reduces dangerous distractions by displaying key information, such as the car’s speed, navigation directions and other alerts, directly in the driver’s line of sight. First adopted for military purposes on fighter jets, HUD is now playing a crucial role inside automotive HMI (Human Machine Interface).

An HUD shows the information in the driver’s field of view, there is no need to look down to the instrument cluster or the secondary display and therefore take the eyes off the road. In the case of a windshield head-up display, drivers are able to see a virtual image as “floating” over the hood at a distance of about 1.5-2 meters.

ST enables your HUD designs with its programmable automotive-grade stepper motor driver, for image adjustment, monitored by a 32-bit control unit, providing a versatile and cost-effective solution. The EVAL-L99SM81V board is available and can drive one bipolar stepper motor in micro-stepping mode.
