Integrated heads-up display and cluster projection panel assembly for motor vehicles
First Claim
1. An integrated heads-up display (HUD) and cluster projection panel assembly for a motor vehicle, the assembly comprising:
- a housing;
a common display unit contained within the housing, the display unit having first and second pixel arrays which are joined together side-by-side and turn on and off for forming different first and second image light beams in response to receiving light, the first and second image light beams being different from one another with the first image light beam forming HUD information and the second image light beam forming cluster projection panel information in which the cluster projection panel information is different than the HUD information;
a HUD unit and a cluster projection panel contained within the housing, the HUD unit and the cluster projection panel sharing the display unit;
the HUD unit having a first converter for transmitting light to the first pixel array of the display unit, the HUD unit further having a first projection optic for projecting the first image light beam from the first pixel array of the display unit onto a windscreen of the motor vehicle in order to project the HUD information onto the windscreen; and
the cluster projection panel having a second converter for transmitting light to the second pixel array of the display unit, the cluster projection panel unit further having a second projection optic for projecting the second image light beam from the second pixel array of the display unit onto a cluster projection screen of the motor vehicle in order to project the cluster projection panel information onto the cluster projection screen.

Abstract
An integrated heads-up display (HUD) and cluster projection panel assembly for a motor vehicle includes a housing and a display unit contained within the housing. The display unit has first and second pixel arrays which turn on and off for forming first and second image light beams in response to receiving light. A HUD unit is contained within the housing. The HUD unit has a first converter for transmitting light to the first pixel array of the display unit. The HUD unit further has a first projection optic for projecting the first image light beam from the first pixel array of the display unit onto a windscreen of the motor vehicle. A cluster projection panel unit is contained within the housing. The cluster projection panel has a second converter for transmitting light to the second pixel array of the display unit. The cluster projection panel unit further has a second projection optic for projecting the second image light beam from the second pixel array of the display unit onto a cluster projection screen of the motor vehicle.

-
3. The assembly of claim 1 wherein:
the cluster projection panel unit includes a second set of light emitting diodes (LEDs) for generating light for second converter to transmit to the second pixel array of the display unit.
-
4. The assembly of claim 1 wherein:
the first converter of the HUD unit is an angle to area converter having a large end for receiving light from an external source and a small end for increasing flux at a higher angle for the light transmitted to the first pixel array of the display unit.
-
5. The assembly of claim 1 wherein:
the HUD unit includes two sets of light emitting diodes (LEDs) for generating light for the first converter to transmit to the first pixel array of the display unit, wherein the first set of LEDs generates light having one color and the second set of LEDs generates light having multiple colors.
-
6. The assembly of claim 5 wherein:
the first pixel array of the display unit forms a first image light beam having one color in response to receiving light from the first set of LEDs.
-
7. The assembly of claim 5 wherein:
the second pixel array of the display unit forms a second image light beam having multiple colors in response to receiving light from the second set of LEDs.
-
8. The assembly of claim 5 wherein:
the first set of LEDs generates the light having one color continuously.
-
9. The assembly of claim 5 wherein:
the second set of LEDs generates the light having multiple colors sequentially to be in synchronicity with the turning on and off of the pixels of the second pixel array of the display unit.
