Pixel and organic light emitting display using the same

摘要

An organic light emitting display capable of improving display quality. The organic light emitting display includes a data driver for supplying bias power supply to data lines in a first period of one frame, for supplying reference power supply in a second period, and for supplying data signals in a fourth period, a scan driver for sequentially supplying scan signals to scan lines in the fourth period, pixels positioned at intersections of the scan lines and the data lines, and a first control line, a second control line, a third control line, and a fourth control line commonly coupled to the pixels. Each of the pixels includes a first capacitor for previously charging voltages corresponding to the data signals and a second capacitor charged by a voltage of the first capacitor in a third period between the second period and the fourth period.
