ABSTRACT:
Structures are disclosed that can improve the visibility of instrument displays. With some implementations, an instrument is provided with an illumination system having a light source and a light diffusion device proximal to the light source. The light diffusion device has at least one surface parallel to a primary plane of the display of the instrument. When the light source is activated, light propagates through the light diffusion device toward the display of the instrument.
