Abstract: The present invention provides a method for driving an Organic Light Emitting Diode (OLED) display apparatus. The method is for displaying a grayscale of one frame with N (N is a natural number equal to or larger than two) number of sub-frames including a writing period and a light-emitting period. Here, M (M is a natural number equal to or smaller than N) number of the sub-frames among the N number of sub-frames include a non-light-emitting period, and a length of the light-emitting period in a specific sub-frame of which a length of the light-emitting period is the shortest is proportional to a difference between a frame time and a time obtained by multiplying a length of the writing period and M.
