Abstract:
1. An organic electro-luminescence display device comprising: a display panel in which a plurality of data lines and a plurality of scan lines cross each other and electro-luminescence elements are arranged at the crosses; a pre-charge driver, which detects a gray level of digital video data to be realized at a Nth display period when a data current corresponding to a gray level of digital video data to be realized at a (N−1)th display period and calculates a pre-charge current corresponding to the detected gray level of digital video data to supply the calculated pre-charge current to the electro-luminescence elements; a data driver for supplying data to the electro-luminescence elements charged with the pre-charge current; and a scan driver for supplying a scan pulse, synchronized with the data, to the scan lines, wherein the pre-charge current is a value as a result from multiplying a current of data to be realized by a maximum value of the pre-charge current and then dividing it by a maximum value of the data current.
