Claim 8:
9. A display device, comprising:
a resonant scanning minor system comprising a scanning minor, a first mirror drive element, and a second minor drive element; and
a drive circuit configured to drive the scanning minor at a resonant frequency, the drive circuit comprising
one or more signal sources configured to create a first source signal and a second source signal, the first source signal being 180 degrees out of phase with the second source signal;
a buffer stage configured to receive the first source signal and the second source signal and to output a first drive signal and a second drive signal respectively based upon the first source signal and the second source signal;
a first resonant LC stage configured to amplify the first drive signal for provision to the first mirror drive element, the first resonant LC stage comprising a first winding of a coupled inductor; and
a second resonant LC stage configured to amplify the second drive signal for provision to the second mirror drive element, the second resonant LC stage comprising a second winding of a coupled inductor.
