Abstract A head-up display system of a vehicle visually transmits information to eyes of an occupant. The head-up display system comprises an illumination device configured to emit a display light and a windshield spaced from the illumination device and extending transverse to the display light. The head-up display system comprises a holographic panel coupled to and extending with the windshield and arranged to diffract the display light toward the eyes of the occupant. The display light emits toward the holographic panel in an entrance direction at an entrance angle relative to an axis normal to the holographic panel and diffracts away from the holographic panel in an exit direction at an exit angle relative to the axis, which is different than the entrance angle.
