An organic light emitting diode (OLED) display device includes: a display panel including a first through (2M)-th row pixel blocks; a data driver including a first data driving unit to provide N odd row data signals to (2K−1)-th row pixel blocks and a second data driving unit to provide N even row data signals to (2K)-th row pixel blocks; a scan driver including a first scan driving unit configured to provide (2K−1)-th scan signals to (2K−1)-th row pixel blocks and a second scan driving unit configured to provide (2K)-th scan signals to (2K)-th row pixel blocks. The first frame period includes an activation period and a vertical blank period. The first scan driving unit is configured to activate the (2K−1)-th scan signals sequentially in pulse form in an activation period.
