An instrument display method and system for use in a passenger vehicle has a number of advantageous features including particularly novel, compact, inexpensive and inherently stable electric motors. A first motor includes a rotor assembly having a shaft and a cylindrical magnet which is positioned about a stator assembly to rotate thereabout. The shaft extends through a stator of the stator assembly, a vacuum fluorescent display (VFD), and an indicia bearing layer. A mask such as a needle pointer is secured to the shaft of the rotor assembly at the indicia bearing layer to convey the value of instrument data to the passenger. A light emitting panel receives light from the VFD and transmits the light to other positions along the display system where other substantially identical electric motors move their needle pointers to likewise convey additional data to the passenger. The first motor is surface mounted directly on the back of the VFD which has electrical conductors formed therein. The other motors are mounted so that their shafts extend through the optical sheet and the indicia bearing layer. In one embodiment, a light beam projecting mechanism projects light beams modified by the various needle pointers to a reflective surface which, in turn, reflects the modified light beams toward the passenger. In another embodiment, the projecting mechanism includes a combiner which projects the modified light beams into the passenger's field of view.

[ What is claimed is:] [1.] In combination with an instrument display system for use in a passenger vehicle to provide a visual representation of instrument data to the passenger, the system being of the type having a mask, an electric motor for moving the mask and control means for controlling movement of the mask, the electric motor being responsive to said control means and having a stator assembly and a rotor assembly for rotating relative to the stator assembly, the improvement wherein:the rotor assembly includes a cylindrical magnet coupled to the mask to move the mask and positioned about the stator assembly for rotating without the stator assembly to enable the mask to convey the instrument data to the passenger; said combination further comprisinga vacuum fluorescent display oriented behind the mask and provided with a plurality of illuminated indicia for projecting an analog gauge image therefrom, the vacuum fluorescent display, mask and motor forming a heads-up projector;a combiner positioned a spaced apart distance from the heads-up projector to form a projected image in the passenger's field of vision;means for affixing the projector to a vehicle windshield; andmeans for adjustably affixing the combiner relative to the vehicle windshield a spaced apart distance from the heads-up projector.
