Simplified Explanation

The abstract describes a device, specifically a wearable display device, that uses a laser diode driver with dynamic voltage control for laser diodes. The device can have different colored laser diodes, such as red, blue, and green. It determines the load condition based on the frame to be displayed and calculates a target voltage level for the laser diode driver based on this load condition. The device generates the target voltage level by adding it to a base voltage level using a voltage booster.


Original Abstract Submitted

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.
