Abstract
A method for controlling an organic electro luminescence display device, the device including a display panel including a plurality of data lines that cross a plurality of scan lines, and including electro luminescence elements arranged at intersections of the plurality of data lines and the plurality of scan lines; a pre-charge driver configured to select one of a plurality of pre-charge current levels in accordance with a gray level of incoming data, and supply a pre-charge current, corresponding to the selected one of the plurality of pre-charge current levels, to the electro luminescence elements via the plurality of data lines prior to supplying a data current, corresponding to the incoming data, to the electro luminescence elements, so as to pre-charge the electro luminescence elements; and a data driver configured to subsequently supply the data current to the pre-charged electro luminescence elements via the plurality of data lines.
