Abstract: A driving device includes an output timing controller which controls an output timing of a first driving voltage and a second driving voltage respectively generated from a first voltage generator and a second voltage generator. A third driving voltage output from the output timing controller is provided to a first data driver and a second data driver, and also provided to a gamma voltage generator to generate a plurality of gamma voltages. Accordingly, a reverse electric potential between the third driving voltage and the gamma voltages is prevented from being generated in the first and second data drivers, therefore, preventing the first and second data drivers from being damaged.

Abstract: Provided are a driver that corrects a distorted image signal and a display device including the driver. The driver includes a control voltage signal generator which converts the voltage level of a control voltage signal according to an external signal, a clock signal generator which generates a clock signal whose duty ratio changes according to the voltage level of the control voltage signal, and a DC-DC converter which converts the level of an input voltage according to the duty ratio of the clock signal supplied from the clock signal generator and outputs the input voltage whose level is converted as a driving voltage.
