ABSTRACT:
A dual use heads-up display panel for a vehicle may be orientated in a first orientation wherein it displays information onto the window of a vehicle. The display panel may be selectively moved to a facing-forward position wherein it directs information towards the operator of the vehicle. The control for the display panel determines which of the two positions the display panel is in, and modifies the information displayed on the panel accordingly. The information should be reversed in a mirror image between the two orientations such that it is properly orientated when read off of the windshield, and is also properly orientated when read from the facing-forward position. In a further feature, a convergent optical system, which may be a lens, is placed in the path of the light from the display panel when in the heads-up position. The lens causes the size of the information displayed on the windshield to be reduced such that its intensity is increased.
