Zusammenfassung:	A micro-projector, a control signal for a micro-projector and a method for generating the same are disclosed. The micro-projector includes a scanning module and a control module. The scanning module includes a micro reflection mirror and at least one scan axis connected to the micro reflection mirror. The control module connected to the scanning module outputs at least one scan axis control signal to the scanning module. The scan axis control signal is a periodic signal and has a waveform which includes a substantially linear portion and a non-linear portion. The proportion of the substantially linear portion to the waveform is larger than that of the non-linear portion to the waveform. In this manner, the unwanted vibration occurring in the micro reflection mirror of the micro-projector can be prevented.
