Abstract
Anomalous images generated by a picture generation unit of a heads up display are suppressed by a light-suppressing horn placed inside the picture generated unit. The horn is sized, shaped and arranged to receive scattered light that is reflected from mirrors of a digital micromirror device, which are in their 'off' position but which nevertheless reflect light toward surfaces of the picture generation unit and which are subsequently emitted from the picture generation unit lens.
