Abstract:
An indicating instrument for a vehicle may employ an analog type lighted pointer arranged on a rotatable, circular shaped pointer disk, a liquid crystal display arranged over the pointer disk, and a first dial with indicia located outboard of or adjacent to and/or inboard of the LCD. A second or inboard dial may be located over the liquid crystal display. The pointer disk may be a translucent light collector for the pointer yet also transmit light to provide backlighting for the LCD. Depending upon the analog gauge arrangement, the pointer may point outboard of the pointer disk or toward the LCD center. The dials, especially the second dial, may be in the shape of rings to permit viewing of the LCD from the perspective of a viewer, such as a vehicle driver.
