PIEZOELECTRICALLY-ACTUATED RESONANT SCANNING MIRROR - A simplified explanation of the abstract

This abstract first appeared for US patent application 17804296 titled 'PIEZOELECTRICALLY-ACTUATED RESONANT SCANNING MIRROR

Simplified Explanation

The abstract describes a scanning mirror system for display devices.

  • The system includes a mirror portion, a flexure arm, and a piezoelectric actuator support portion.
  • The piezoelectric actuator is made of a piezoelectric film.
  • A transmission arm is used to transmit motion from the piezoelectric film to the flexure arm.
  • The transmission arm is separated from the piezoelectric actuator support portion by a first gap.
  • An anchor portion is included to anchor the scanning mirror system to another structure.
  • The anchor portion is separated from the piezoelectric actuator support portion by a second gap.


Original Abstract Submitted

Examples are disclosed that relate to scanning mirror systems for display devices. One example provides a scanning mirror system comprising a mirror portion, a flexure arm extending from the mirror portion, and a piezoelectric actuator support portion supporting a piezoelectric actuator comprising a piezoelectric film. The scanning mirror system further comprises a transmission arm extending between the flexure arm and the piezoelectric actuator support portion to transmit motion of the piezoelectric film to the flexure arm, the transmission arm separated at least partially from the piezoelectric actuator support portion by a first gap. The scanning mirror system further comprises an anchor portion separated at least partially from the piezoelectric actuator support portion by a second gap, the anchor portion configured to anchor the scanning mirror system to another structure.
