Abstract

A substantially transparent windscreen head up display includes one of light emitting particles or microstructures over a predefined region of the windscreen permitting luminescent display while permitting vision through the windscreen. A method to display a graphic head up instrument display upon a substantially transparent windscreen head up display of a vehicle includes monitoring operation of the vehicle, monitoring an operator-defined configuration of the graphic head up instrument display, determining the graphic head up instrument display based upon the operation of the vehicle and the operator-defined configuration of the graphic head up instrument display, and displaying the graphic head up instrument display upon the substantially transparent windscreen head up display.

5. The method of claim 1, wherein the operator-defined configuration comprises a location of the always-displayed and potentially-displayed elements of the graphic head up instrument display upon the substantially transparent windscreen head up display.

6. The method of claim 5, wherein the operator-defined configuration further comprises a style of the elements of the graphic head up instrument display.

7. The method of claim 6, wherein the style of the elements of the graphic head up instrument display comprises a display method selected from the group consisting of a numeric representation, a color coded numeric representation, a dial representation, a linear meter representation, and a historical plot representation.

8. The method of claim 5, wherein the operator-defined configuration further comprises a size of the elements of the graphic head up instrument display.

9. The method of claim 5, wherein the operator-defined configuration further comprises a color of the elements of the graphic head up instrument display.

10. The method of claim 5, wherein the operator-defined configuration further comprises an image intensity of the elements of the graphic head up instrument display.

11. The method of claim 10, wherein the human machine interface device comprises a movement input and a button selector configured to operate a configuration setting upon the substantially transparent windscreen head up display.

12. The method of claim 1, wherein the operator-defined configuration comprises locations of a plurality of always-displayed and potentially-displayed elements of the graphic head up instrument display upon the substantially transparent windscreen head up display.

13. The method of claim 1, wherein monitoring an operator-defined configuration of the graphic head up instrument display comprises monitoring a human machine interface device within the vehicle configured to receive operator changes to the operator-defined configuration.

14. The method of claim 13, wherein the human machine interface device comprises a touch screen device.

15. The method of claim 1, wherein monitoring an operator-defined configuration of the graphic head up instrument display comprises:
