发明名称 Data driving circuits and organic light emitting diode display using the same
摘要 <p>A data driving circuit for driving pixels of a display to display images with uniform brightness may include a gamma voltage unit that generates gray scale voltages, a digital-analog converter that selects, as a data signal, one of the gray scale voltages using first data, a decoder that generates second data using the first data, a latch for storing the first data and the second data, a current sink that 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, 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.</p>
