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 scanning (“LBS”) display device is configured with an optical system that includes a laser beam emitter configured to emit a laser beam. The optical system also includes a driver configured to generate a driving signal for controlling a mirror, such as a microelectromechanical systems (“MEMS”) mirror. The optical system also includes an output limiter configured to limit an amplitude of the driving signal provided to the mirror to a bounded range. The output limiter might be implemented as hardware, software, or a combination of hardware and software.

Abstract: A display device, including a display surface, a laser beam emitter, and a processor. The display device may further include a slow-scan MEMS driver configured to drive a slow-scan mirror and a fast-scan MEMS driver configured to drive a fast-scan mirror. The slow-scan mirror and the fast-scan mirror may reflect the laser beam onto an active region of the display surface. The slow-scan period may include a scanning interval in which the slow-scan mirror is configured to move to a final scanning position at one or more scanning ramp rates and a flyback interval in which the slow-scan mirror is configured to return to the initial scanning position. The processor may generate a modified slow-scan drive signal by modifying one or more of the initial scanning position, the final scanning position, and the scanning ramp rate in a blank region of the display surface.

Abstract: A display device is provided, including a laser beam emitter, a fast-scan driver system including a nonlinear driver and a fast-scan MEMS sensor, and a slow-scan MEMS driver. The nonlinear driver and the slow-scan MEMS driver may respectively drive a fast-scan mirror and a slow-scan mirror. The display device may further include a signal generator configured to generate a periodic electrical signal. The nonlinear driver may receive, amplify, and drive the fast-scan mirror with the amplified electrical signal. The fast-scan MEMS sensor may detect a motion of the fast-scan mirror. The display device may further include a signal detector configured to receive and detect an amplitude difference between a periodic electrical signal and a fast-scan MEMS sensor output signal. The display device may further include a processor configured to receive the amplitude difference and determine a driver system resonant frequency of the fast-scan driver system.
