摘要： An apparatus includes a light-emitting diode (LED) driver circuit, one or more LEDs of an LED array, and an electronic switching circuit. The LED driver circuit is configured to generate an electric current. The one or more LEDs are electrically connected to the LED driver circuit. The electronic switching circuit is electrically connected to the one or more LEDs and configured to be placed in one of multiple switching configurations. The electronic switching circuit is further configured to direct a portion of the electric current away from the one or more LEDs, such that a remaining portion of the electric current drives the one or more LEDs. The portion of the electric current corresponds to the one of the multiple switching configurations.

摘要： An augmented reality display system can include a partially transparent eyepiece, an ambient light sensor, and an image input device. The image input device can include a light source and a spatial light modulator. The system can also include a controller that determines that no virtual content is being displayed to the user and compares the ambient light to display light to determine if a light source shutoff criterion is satisfied. If the light source shutoff criterion is satisfied, the controller can turn off the light source.

摘要： An augmented reality display system is disclosed. The system can include a partially transparent eyepiece, an ambient light sensor, and an image input device. The image input device can include a light source and a spatial light modulator. The system can also include a controller that determines that no virtual content is being displayed to the user and compares the ambient light to display light to determine if a light source shutoff criterion is satisfied. The light source shutoff criterion can be indicative of whether shutting off the light source that illuminates the spatial light modulator will result in a change in the display light that will be user-perceptible. If the light source shutoff criterion is satisfied, the controller can turn off the light source.
