ABSTRACT:
The present invention provides an organic electroluminescence panel, an organic electroluminescence display provided therewith, and driving apparatus and method thereof. The organic electroluminescence display according to the present invention includes a plurality of display groups obtained by grouping organic electroluminescence display cells associated with predetermined numbers of scanning lines. Each display cell includes a driving transistor having a first terminal connected to a second terminal of an organic electroluminescence element and a second terminal connected to a second polarity terminal and controlling current flow from a first polarity terminal to the second polarity terminal or vice versa in response to the output data signal from a third terminal of a switching transistor to control light-emission of the organic electroluminescence element. The light emission of a current display group area among the display groups and the scanning of a next display group area are simultaneously performed. As a result, the present invention improves the brightness without adding a switching transistor in each organic EL display cell, a signal selecting line for each scanning line, and a row driving IC. In addition, the present invention is capable of manufacturing an organic EL display device at low cost and increasing its yield.
