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.
