Data driving circuit and driving method of light emitting display using the same

Abstract

A data driving circuit capable of displaying images having uniform brightness. The present invention provides a data driving circuit of a display device having: at least one current sinking unit for controlling a predetermined current to flow in a data line; at least one voltage generating unit for resetting voltage values of enhancement voltages using a compensation voltage generated when the predetermined current flows; at least one digital-analog converter for selecting as a data signal one of the enhancement voltages to correspond to a digital value of externally supplied data; at least one boosting unit for boosting a voltage value of the data signal; and at least one switching unit for providing the data line with the boosted data signal.
