Abstract

An instrument cluster assembly includes a dial face having a plurality of first indicia disposed thereon. A pointer is configured to selectively point to the plurality of first indicia disposed on the dial face. A selectable light blocker is disposed over the dial face and the pointer. The selectable light blocker is configured to be reconfigured between a see-through mode and a blocking mode. In the see-through mode, a user can see the dial face and the pointer through the selectable light blocker. In the blocking mode, the user is substantially blocked from seeing the dial face and the pointer. A see-through digital electronic display is disposed over the dial face. The selectable light blocker is disposed between the pointer and the see-through digital electronic display. The see-through digital electronic display is configured to electronically generate a plurality of second indicia.

First claim

What is claimed is:

1 . An instrument cluster assembly comprising:
a dial face including a plurality of first indicia disposed thereon; a pointer rotatable about a central axis, the pointer configured to selectively point to the plurality of first indicia disposed on the dial face; a selectable light blocker disposed over the dial face and the pointer, wherein the pointer is disposed between the dial face and the selectable light blocker, the selectable light blocker configured to be changed between a see-through mode and a blocking mode, wherein in the see-through mode, a user can see the dial face and the pointer through the selectable light blocker, and wherein in the blocking mode, the user is substantially blocked from seeing the dial face and the pointer; and a see-through digital electronic display disposed over the dial face, the pointer, and the selectable light blocker, the selectable light blocker being disposed between the dial face and the see-through digital electronic display, the see-through digital electronic display configured to electronically generate a plurality of second indicia.

2 . The instrument cluster assembly of claim 1 , wherein the selectable light blocker is electronically activatable to change the selectable light blocker between the see-through mode and the blocking mode by causing the light blocker to appear substantially opaque in the blocking mode.

3 . The instrument cluster assembly of claim 2 , wherein the selectable light blocker comprises electro-chromatic material.

4 . The instrument cluster assembly of claim 3 , the selectable light blocker being electronically activatable to change the selectable light blocker between the see-through mode and the blocking mode by applying at least one of a current and a voltage to the selectable light blocker.

5 . The instrument cluster assembly of claim 4 , wherein the instrument cluster assembly is selectively reconfigurable to operate in first mode wherein the selectable light blocker is in the see-through mode and the dial face and the pointer are viewable by a user; the instrument cluster assembly being selectively reconfigurable to operate in a second mode wherein the selectable light blocker is in the blocking mode and the see-through digital electronic display generates a plurality of second indicia that are visible to the user in front of the light blocker in a direction as viewed by the user.

6 . The instrument cluster assembly of claim 5 , further comprising a plurality of light sources configured to provide back-lighting for the see-through digital electronic display.

7 . The instrument cluster assembly of claim 6 , the plurality of light sources comprising a plurality of light-emitting diodes.

8 . The instrument cluster assembly of claim 7 , the plurality of light sources being a plurality of first light sources, the instrument cluster assembly further comprising a plurality of second light sources configured to illuminate at least one of the pointer and the dial face.

9 . The instrument cluster assembly of claim 8 , the plurality of first light sources being located between the selectable light blocker and the see-through digital electronic display.

10 . The instrument cluster assembly of claim 9 , the dial face being disposed between the pointer and the plurality of second light sources.

11 . The instrument cluster assembly of claim 10 , wherein the see-through digital electronic display is a substantially transparent liquid crystal display (LCD).

12 . The instrument cluster assembly of claim 10 , wherein the see-through digital electronic display is one of a substantially transparent organic light-emitting diode (OLED) display, a picture generation unit (PGU) having a projector and a lens, and a thin film transistor (TFT) display.

13 . An instrument cluster assembly comprising:
a dial face including a plurality of first indicia disposed thereon; a pointer configured to selectively point to the plurality of first indicia disposed on the dial face; a selectable light blocker disposed over the dial face and the pointer, the selectable light blocker configured to appear substantially see-through in a see-through mode and to appear substantially opaque in a blocking mode, wherein in the see-through mode, a user can see the dial face and the pointer through the selectable light blocker, and wherein in the blocking mode, the user is substantially blocked from seeing the dial face and the pointer; and a see-through digital electronic display disposed over the dial face, the selectable light blocker being disposed between the pointer and the see-through digital electronic display, the see-through digital electronic display configured to electronically generate a plurality of second indicia, the see-through digital electronic display being one of a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, a thin film transistor (TFT) display, and a picture generation unit (PGU) having a projector and a lens.

14 . The instrument cluster assembly of claim 13 , the selectable light blocker comprising electro-chromatic material, wherein the selectable light blocker is electronically activatable to change the selectable light blocker between the see-through mode and the blocking mode by applying a current to the selectable light blocker.

15 . The instrument cluster assembly of claim 14 , wherein the instrument cluster assembly is selectively reconfigurable to operate in first mode wherein the selectable light blocker is in the see-through mode and the dial face and pointer are viewable by a user; the instrument cluster assembly being selectively reconfigurable to operate in a second mode wherein the selectable light blocker is in the blocking mode and the see-through digital electronic display generates a plurality of second indicia that are visible to the user in front of the light blocker.

16 . The instrument cluster assembly of claim 15 , wherein the dial face comprises a dead-front lens material, the dial face being disposed between the pointer and the selectable light blocker, the instrument cluster assembly further comprising a plurality of light sources configured to provide back-lighting for the see-through digital electronic display, the plurality of light sources being disposed between the selectable light blocker and the see-through digital electronic display.

17 . The instrument cluster assembly of claim 16 , the plurality of light sources being a plurality of first light sources, the instrument cluster assembly further comprising a plurality of second light sources configured to illuminate at least one of the pointer and the dial face, the pointer being disposed between the dial face and the plurality of second light sources.

18 . A selectable instrument cluster system for a motor vehicle, the system comprising:
a dial face including a plurality of first indicia disposed thereon; a pointer configured to selectively point to the plurality of first indicia disposed on the dial face; a selectable light blocker disposed over the dial face and the pointer; and a see-through digital electronic display disposed over the dial face, the pointer, and the selectable light blocker, the selectable light blocker being disposed between the dial face and the see-through digital electronic display, the see-through digital electronic display configured to selectively electronically generate a plurality of second indicia, wherein the system is configured to operate in an analog mode and a digital mode, wherein the user may select betw
