Patent ID: 7616178

Claim:
A driving device for controlling a current applied to a light emitting diode, comprising: a first driving part connected to the light emitting diode, the first driving part including a first driving transistor; a second driving part connected to the light emitting diode, the second driving part including a second driving transistor; a first switching part including first and second switching transistors, the first switching transistor for being activated by a scan signal from a first scan line during a first frame to apply a first data voltage inputted from a first data line to the first driving transistor and the second switching transistor for being activated by the scan signal from the first scan line during the first frame to apply a second data voltage inputted from a second data line to the second driving transistor; and a second switching part including third and fourth switching transistors, the third switching transistor for being activated by a scan signal from a second scan line during a second frame to apply the first data voltage inputted from the first data line to the second driving transistor and the fourth switching transistor for being activated by the scan signal from the second scan line during the second frame to apply the second data voltage inputted from the second data line to the first driving transistor, wherein the first data voltage has a positive magnitude and the second data voltage has a negative magnitude during each of the first and second frames.
