Abstract:
1. A display device, comprising: a display unit including a plurality of pixels, a plurality of scan lines, and a plurality of data lines; a data driver transmitting a plurality of data signals to the plurality of data lines; a scan driver transmitting a plurality of scan signals to the plurality of scan lines; a compensation controller supplying a predetermined test current to each organic light emitting diode in each of the plurality of pixels during a sensing period for measuring a driving voltage of the organic light emitting diode for each of the plurality of pixels, receiving the driving voltage of the organic light emitting diode supplied with the first current, and outputting measuring data for the transmitted driving voltage; a signal controller compensating an input video signal according to the measuring data to generate image data, wherein the compensation controller is separate from and external to the data driver, wherein the compensation controller is connected to one data line of the plurality of data lines during the sensing period, and detects the driving voltage of at least one organic light emitting diode among the plurality of organic light emitting diodes connected to one data line; and a selection unit including:
