Abstract

A display unit for mounting in a vehicle may include an image generator, a display member, and a light source. The display member may be configured to move from a non-operational position to an operational position such that the display member is positioned to reflect light from the image generator in the operational position. The display member also includes an edge configured to refract light and/or otherwise be illuminated. The light source may be configured to emit light to illuminate at least a portion of the edge of the display member. In some implementations, the light source may move when the display member is moved from the non-operational position to the operational position. In other implementations, the light source may be stationary. The display unit may also include a light guide to guide the light emitted by the light source to illuminate the edge.
