  • TECHNIQUES FOR DYNAMIC VOLTAGE CONTROL FOR LASER DIODES IN HEAD-WEARABLE DISPLAY DEVICES
    Publication number: 20230327401
    Abstract: The present disclosure relates generally to a device, such as a wearable display device configured with a laser diode driver implementing dynamic voltage control for laser diodes. The laser diodes may include one or more of a red laser diode, a blue laser diode, and a green laser diode. The device may determine a load condition based on a frame to be displayed at the device, and determine a target voltage level for a laser diode operably coupled to the laser diode driver of the device based on the load condition (e.g., an image signal processor (ISP) frame buffer load). The device may generate the target voltage level for the laser diode based on a base voltage level. For example, the device may be configured with a voltage booster operably coupled to the laser diode driver to provide the target voltage level in addition to the base voltage level.

  • Combiner lens fault detection system
    Patent number: 11662579
    Abstract: A combiner lens system includes a lens and a lightguide in stack with the lens. The lightguide carries one or more electrically conductive traces. A detector circuit is electrically coupled to the one or more electrically conductive traces to form an electrical circuit. The detector circuit monitors the electrical circuit for an open circuit or a short circuit and generates an output signal that is indicative of a state of the electrical circuit.
