Abstract: The techniques disclosed herein provide methods and systems that adaptively adjust control system update rates to optimize power consumption for laser beam scanning display devices. A display device can adjust an update rate based on changes within the system and/or changes of a surrounding environment, e.g., vibration level, a humidity level, a temperature, a resonant frequency, and/or an age of a device. As variations of the environmental properties change, the device can increase or decrease the control system update rates. Additionally, or alternatively, the system can perform a resonance calibration process to determine a resonant frequency. Based on a change in a determined resonant frequency, the system may increase or decrease the control system update rates. By dynamically controlling the system update rates based on environmental and/or physical properties of a device, the device can optimize power consumption while maintaining a desirable image quality.

Abstract: A laser beam display device that can dynamically control the resonant frequency of a mirror is provided. The increase the reliability of a device by controlling the resonant frequency of a mirror instead of requiring components of a display device to react to changes in the resonant frequency of a mirror.

In some embodiments, the controller can also receive a feedback signal from a mirror indicating a current resonant frequency. The controller can also bias the input signal to increase or decrease the current resonant frequency. By dynamically controlling the resonant frequency of a mirror, a device can minimize any difference between the current resonant frequency detected in a feedback signal and the target resonant frequency.
