Patent ID: 8723853

Claim:
A driving device comprising: a first voltage generator which receives a power voltage from an exterior power source and outputs a first driving voltage; a second voltage generator which receives the power voltage and outputs a second driving voltage; an output timing controller which receives the first and second driving voltages from the first and second voltage generators, respectively, and outputs a third driving voltage and a fourth driving voltage in response to the first and second driving voltages; a gamma voltage generator which receives the third driving voltage from the output timing controller and outputs a plurality of gamma voltages; a first data driver which operates in response to the third driving voltage from the output timing controller to change a first image signal to a first data signal based on the gamma voltages provided from the gamma voltage generator; and a second data driver which operates in response to one of the third driving voltage and the fourth driving voltage from the output timing controller to change a second image data to a second data signal based on the gamma voltages provided from the gamma voltage generator, wherein the output timing controller simultaneously outputs the third driving voltage and the fourth driving voltage to the first and second data drivers.
