Drive circuit for resonant mirror scanning system

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.

A method of operating a scanning minor system of a display device, comprising:

• generating a first source signal and a second source signal, the first source signal and the second source signal being 180 degrees out of phase;
• inputting the first source signal and the second source signal into a buffer stage and outputting a first drive signal and a second drive signal from the buffer stage;
• amplifying the first drive signal at a resonant frequency of a resonant minor via a first resonant LC stage;
• amplifying the second drive signal at the resonant frequency of the resonant mirror via a second resonant LC stage;
• providing the first drive signal to a first minor drive element;
• and
• providing the second drive signal to a second mirror drive element.
