Abstract

Aspects of the present invention relate to context based power management of a head-worn computer.

Claims

1. A display system with reduced power usage that displays an image over a see-through display area comprising:

a. a light source with multiple portions that can be operated independently;

b. a light distribution system that provides light from each portion of the light source to illuminate a corresponding area of the display; and

c. a control system to turn OFF portions of the light source that are associated with portions of the display area where there is no image content in a corresponding section of the see-through display.

2. The display system of claim 1 wherein the light source includes multiple LEDs.

3. The display system of claim 1 wherein the light source includes multiple backlights.

4. The display system of claim 1 wherein the light source includes diffusers with elliptical lighting patterns.

5. The display system of claim 1 wherein the displayed image is compressed to provide portions of the display area where there is no image content.
