    Abstract: Techniques are described herein that are capable of adjusting a center frequency of an adaptive voltage controlled oscillator (VCO) that is included in an adaptive phase lock loop (PLL) and/or a phase difference target of the adaptive PLL. An adaptive PLL is a PLL that includes an adaptive VCO. An adaptive VCO is a VCO that is capable of adjusting its center frequency and/or a phase difference target of the adaptive PLL that includes the adaptive VCO. The adaptive PLL may be configured to drive (e.g., control) a device. A drive signal that is used to drive the device and a resulting output signal that is proportional to movement of the device may be fed back to respective inputs of the adaptive PLL so that the phases of those signals may be processed to facilitate adjustment of the center frequency and/or the phase difference target.

  • Patent number: 11614615
    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. A controller can drive a mirror with an input signal, receive a signal or data indicating a target resonant frequency, and bias the input signal to control the resonant frequency of the 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.

    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.
