Abstract
Briefly, in accordance with one or more embodiments, a scanner for a scanned beam display may comprise a scanning platform having a mirror disposed thereon to reflect a beam of light impinging on the mirror, a drive coil disposed on the scanning platform to scan the reflected beam of light in response to a drive current applied to the drive coil. The drive coil has coil winding segments having a narrower width in one or more regions of the drive coil, and has coil winding segments having a greater width in one or more other regions of the drive coil to provide a the drive coil with a reduced electrical resistance.
