Abstract: An organic light emitting display and a method of driving the display are disclosed. The display uses an automatic current limit driving method. The method includes comparing current and previous frames of data to select a peak brightness ratio for displaying the current frame. If the difference between the frames is greater than a threshold, the peak brightness ratio of the previous frame is used for the current frame.
