Abstract: A flicker reduction device of a display apparatus can include a frame memory configured to store image data of an input frame synchronized with an input frame frequency, a first circuit configured to output a first control signal when a plurality of fixed active periods based on a reference frame frequency are allocated within each input frame time corresponding to the input frame frequency and output a second control signal when only one fixed active period is allocated within each input frame time, and a second circuit configured to copy the image data of the input frame according to the first control signal and output image data of a plurality of input frames according to the reference frame frequency. The second circuit outputs the image data of the input frame according to the reference frame frequency without copying according to the second control signal.
