摘要： The present invention relates to an organic electroluminescent display device and a method for driving the same, capable of displaying an image having uniform luminance. The organic electroluminescent display device according to an embodiment of the present invention comprises: a pixel unit including pixels which are arranged in a matrix with multiple columns and rows; a data driving unit providing the pixel unit with first data signals corresponding to first data or second data signals corresponding to second data which is made by converting the first data in response to a data control signal; and a compensation unit converting, to output voltages, output currents outputted from the pixels in correspondence to the first data signals, and providing the data driving unit with the data control signal to convert the first data to the second data in correspondence to the output voltages and the first data.
