Abstract:
1. An organic light emitting display comprising: a display unit comprising data lines, scan lines, emission control lines, and a plurality of pixels coupled to the data lines, the scan lines, and the emission control lines; a data driver coupled to the data lines for transmitting data signals; a scan driver coupled to the scan lines for transmitting scan signals; an emission control driver coupled to the emission control lines for transmitting emission control signals; and a controller for transmitting a plurality of control signals for controlling the data driver, the scan driver, and the emission control driver, and outputting a first control signal to prevent currents from flowing to organic light emitting diodes of the pixels, wherein the emission control driver further comprises a switch for outputting a voltage of a first power source to an output end of the emission control driver for outputting the emission control signals in response to the first control signal, wherein, after the first control signal is transmitted, voltages of a pixel power source and a base power source are transmitted to the pixels, and the data driver is configured to generate and transmit a black data signal to the pixels from a point in time in which the voltages of the pixel power source and the base power source begin to be transmitted to the pixels to a point in time after the emission control driver generates the emission control signals, wherein, after at least one frame elapses after the voltages of the pixel power source and the base power source are transmitted, the scan driver operates starts to be driven.
