1. A personal display device for displaying virtual images to a wearer, comprising:
a frame having one or more temple sections;
a battery arranged within the one or more temple sections;
a projection display device connected to the frame operable to project image-bearing light beams;
a processor connected to the projection display device and arranged within the one or more temple sections;
a circuit board arranged within the one or more temple sections;
at least one waveguide stack module connected to the frame, the at least one waveguide stack module configured to receive the image-bearing light beams from the projection display device, the at least one waveguide stack module including:
an in-coupling diffractive optic formed along the at least one waveguide stack module operable to diffract at least a portion of the image-bearing light beams from the projection display device into the at least one waveguide stack module in an angularly encoded form; and
an out-coupling diffractive optic formed along the at least one waveguide stack module operable to diffract at least a portion of the image-bearing light beams from the at least one waveguide stack module in an angularly decoded form;
a heat spreader system arranged within the one or more temple sections, comprising a heat conductive sheet arranged between at least a portion of the processor and at least a portion of the battery.
