Abstract
A head-up-display (HUD) device is disclosed and includes a plurality of light-emitting diodes (LEDs) configured to emit light beams in response to a control module of a vehicle generating a safety warning. The control module includes a processor that is configured to execute instructions stored in a nontransitory computer-readable memory. The HUD device also includes a first mirror that includes a transparent portion on a first side of the first mirror and a diffusive portion on a second side of the first mirror, and the light beams are configured to pass through the first mirror. The HUD device also comprises a second mirror that is configured to reflect the light beams toward a first reflective surface, and the second mirror is configured to reflect the light beams subsequent to the light beams passing through the first mirror.
