Abstract
A data driving circuit for driving pixels of a light emitting display to display images with uniform brightness may include a gamma voltage unit that generates a plurality of gray scale voltages, a digital-analog converter that selects, as a data signal, one of the plurality of gray scale voltages using first data, a decoder that generates second data using the first data, a current sink, a voltage controller that controls a voltage value of the data signal using the second data and a compensation voltage generated based on the predetermined current, and a switching unit that supplies the data signal to the pixel during any partial period of the complete period elapsing after the first partial period. The current sink receives a predetermined current from the pixel during a first partial period of a complete period for driving the pixel based on the selected gray scale voltage.
