ABSTRACT:
A transreflective instrument display has a generally planar reverse image light emitting display panel, a transflector surface positioned at a predetermined angle with respect to the display panel. The transflector has a P-plane reflectance and S-plane reflectance. A illuminated pointer is positioned behind the transflector. The display is formed of light transmitted from the pointer and reflecting light from said display panel simultaneously to form an image. The transflector is preferably coated with a coating that increases the reflectivity of the P-plane polarization of the transflector.
