Abstract:
1. An organic light emitting diode display device, comprising: a display panel including a plurality of data lines, a plurality of gate line pairs crossing the data lines, and a plurality of light emitting cells which include an organic light emitting diode device, first and second cell driving circuits for alternately driving the organic light emitting diode device; a data voltage generator supplying a data voltage of a first polarity to the data lines; a compensation voltage generator supplying a compensation voltage of a second polarity to the data lines; and a scan driver for sequentially supplying scan pulses to the gate line pairs, wherein first electrodes of the first and second cell driving circuits are commonly connected to one electrode of the organic light emitting diode device, wherein the first and second cell driving circuits are alternately supplied with the data voltage and the compensation voltage in response to the scan pulses to alternately driven the organic light emitting diode, wherein the first cell driving circuit is supplied with the data voltage during a first emission period, and supplied with the compensation voltage during a first non-emission period; and the second cell driving circuit is supplied with the data voltage during a second emission period overlapping with the first non-emission period of the first cell driving circuit, and supplied with the compensation voltage during a second non-emission period overlapping with the first emission period of the first cell driving circuit, and wherein the scan driver supplies a first scan pulse synchronized with the data voltage to the first gate lines included in the gate line pairs within a first period and then supplies the first scan pulse synchronized with the compensation voltage to the first gate lines within a second period; and supplies a second scan pulse synchronized with the compensation voltage to the second gate lines included in the gate line pairs within the first period and then supplies the second scan pulse synchronized with the data voltage to the second gate lines within the second period.
