ORGAINIC LIGHT EMITTING DISPLAY AND DRIVING METHOD FOR THE SAME

摘要

Provided is an organic light emitting display device. The organic light emitting display device may include a data driving part which generates a data signal according to image data provided by a timing control part, and provides the generated data signal to a plurality of data lines; a display panel which includes a pixel part which controls a current amount flowing from a first power terminal to a second power terminal in response to the data signal provided through the data lines, and a dummy pixel part which has a plurality of dummy pixel circuits which receive the data signal through the data lines; and a compensation signal generation part which compares and calculates a current flowing along the pixel part and a current flowing along the dummy pixel part, and generates a compensation signal. So, the deterioration and an afterimage phenomenon can be prevented.
