ABSTRACT:
A method of activating a micro-mirror includes applying a first electrode voltage to one or more electrodes associated with the micro-mirror. The micro-mirror is positioned at a first positive deflection angle during a portion of the application of the first electrode voltage. The method also includes maintaining the first electrode voltage for a first predetermined time and applying a second electrode voltage to the one or more electrodes. The micro-mirror rotates to a first negative deflection angle during a portion of the application of the second electrode voltage. The method further includes maintaining the second electrode voltage for a second predetermined time and applying a third electrode voltage to the one or more electrodes. The micro-mirror is positioned at a second positive deflection angle greater than the first positive deflection angle during a portion of the application of the third electrode voltage.
