Abstract
A display device includes a data driver and a pixel current measuring unit. The data driver applies data signals to a plurality of data lines connected to a plurality of pixels. The pixel current measuring unit measures current flowing to the data lines in order to sense a state of degradation of the pixels. The data driver and pixel current measuring unit are integrally formed in one-body-type connected to the data lines.
Claims20
