Patent ID: 8462087

Claim:
An organic light emitting diode display device comprising: a display panel where pixels having an organic light emitting diode device is arranged in a matrix; a data driver that supplies any one of a data voltage and an inverted voltage of the data voltage to any one pixel of two pixels adjacent in a vertical and horizontal directions and supplies another one of the data voltage and the inverted voltage to another pixel of the two pixels for a first half frame period of one frame period, and supplies the another one of the data voltage and the inverted voltage to the another one pixel of the two pixels and supplies the any one of the data voltage and the inverted voltage to the any one pixel of two pixels for a second half frame period of the one frame period, wherein the inverted voltage is symmetric to the data voltage relative to a reference voltage; a scan driver that sequentially supplies scan signals to scan lines for the first half frame period of the one frame period, and sequentially supplies the scan signals to the scan lines for the second half frame period of the one frame period, wherein a same scan signal is supplied to each of the scan lines twice during the first and second half frame periods of the one frame period; a drive device that drives the organic light emitting diode device using the data voltage and the inverted voltage; a high level voltage source that supplies a high level power supply voltage to the drive device; a low level voltage source that supplies a low level power supply voltage to a cathode electrode of the organic light emitting diode; a switch device that alternately supplies the data voltage and the inverted voltage from data lines to a gate electrode of the drive device in response to the scan signal from the scan line; a p-decoder configured to convert digital video data into voltages of a first polarity; an n-decoder configured to convert the digital video data into voltages of a second polarity; multiplexers configured to alternately output the voltages of the first polarity and the voltages of the second polarity by a ½ frame period unit of the one frame period in response to a polarity control signal; and an inverter connected to an input terminal of even numbered multiplexer of the multiplexers, wherein the reference voltage comprises a positive voltage larger than 0V.
