<p>PURPOSE: The present invention is to provide a method for setting a position of afterimage removal object. The method enables a user to manually or automatically select points where an afterimage is continuously generated in an organic light emitting display device by using an afterimage removal algorithm. CONSTITUTION: A method for driving an organic light emitting device comprises the steps of selecting points where an afterimage is continuously generated by analyzing images displayed in each of frames (S310), storing the sum of image data corresponding to each of selected points in a memory unit (S330), setting a data change threshold value (S350), comparing a change amount of data sum with the data change threshold value (S370), and continuously reducing a light emitting cycle if the change amount of data sum is smaller than the data change threshold value (S390). [Reference numerals] (AA) Start; (BB) End; (S310) Organic light emitting display device selects certain points where afterimages appear by analyzing images displayed in each frame; (S330) Organic light emitting display device sums up image data corresponding to the selected points and stores it as a data sum in a memory unit; (S350) Organic light emitting display device sets a data change critical value; (S370) Organic light emitting display device compares changes in the data sum with the data change critical value; (S390) Organic light emitting display device reduces continuously the light emitting period with the changes in the data sum smaller than the data change critical value, while resetting the light emitting period and storing new image data in the next frame as the data sum in the memory unit with the changes in the data sum larger than the data change critical value</p> |
