Organic light emitting diode display device in which adjacent sub pixels share a single data line and driving method thereof wherein same-colored sub pixels continue to emit light based on a unit of horizontal periods

An organic light emitting diode display device, comprising:

• an organic light emitting diode display panel where sub pixels adjacent to each other along a direction of a gate line among gate lines are paired and arranged to share a single data line among data lines in pixel areas defined by the gate lines and the data lines;
• a timing controller configured to align and output image data so that same-colored sub pixels continue to emit light based on a unit of a plurality of predetermined horizontal periods, and to generate gate and data control signals so that a predetermined driving period of sub pixels is changed;
• a gate driver configured to change an output period of gate-on signals according to the gate control signal, and to consecutively supply the gate-on signals with changed output period to the gate lines;
• and
• a data driver configured to generate a data voltage corresponding to the image data aligned by the timing controller, and to output the data voltage to each of the data lines so that the data voltage is synchronized with a timing of supply of the gate-on signal according to the data control signal.
