摘要： In a method for driving a micro mirror such as MEMS mirror and a display apparatus using the method, there are provided a mirror driving unit for driving the micro mirror which operates in a resonant mode and a nonresonant mode, a driving-condition setting unit for setting a mirror driving condition, a switching unit for switching on/off a mirror driving signal in the nonresonant mode, and a look-up table for indicating the relationship of a mirror response with respect to the driving condition already known in advance. The switching unit controls the transmission of the nonresonant-mode mirror driving signal while grasping the mirror response state with respect to the mirror driving signal, thereby finely increasing and decreasing a driving torque for the micro mirror. This fine increase and decrease allows the micro mirror to be fluctuated stably, and a further enhancement in the fluctuation rate.
