Abstract: The present invention provides an organic light emitting diode (OLED) display apparatus displaying a grayscale of one frame with N number of subfields. The OLED display apparatus includes a display panel where pixels are defined by an intersection of data lines and gate lines, a gate driving unit that provides a scan signal to the gate line, and a data driving unit that controls a data voltage in an analog manner. Here, the data voltage is provided to the data line in at least one subfield.
