Method for driving light deflector, light deflector, light deflection array, image forming device, and image projection display apparatus

摘要

A method for driving a light deflector the method includes turning over a direction of an electric field acting on the plate shape member, in an optional period. In the method, the light deflector deflects a beam incident on a light reflection area by displacing a plate shape member having the light reflection area with an electrostatic force. The light deflector includes a substrate, a plurality of control members, a fulcrum member, the plate shape member, and a plurality of electrodes.
