Patent ID: 8723846

Claim:
A method of increasing a perceived resolution of a display comprising: directing light at an optical dithering element; and repeatedly transitioning the optical dithering element from a first position to a second position and then back to the first position such that the optical dithering element alternately directs light to a first position on the display and then to a second position on the display; wherein each transition of the optical dithering element comprises controlling any overshoot or ringing in the position of the optical dithering element by providing a predetermined control signal to the optical dithering element; wherein a resonant response period is defined as a time period between the beginning of a transition from the first position to the second position and the beginning of the next subsequent transition from the second position to the first position; and wherein the predetermined control signal comprises: a step pulse having a first magnitude and having a width of approximately twenty percent of the resonant response period; and a quench pulse immediately following the step pulse, the quench pulse having a magnitude equal to the first magnitude but opposite in direction and having a width of approximately fourteen percent of the resonant response period.
