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: A liquid crystal display includes; a liquid crystal panel, and a DC-DC converter which receives an input voltage to generate an analog drive voltage and a gate-on voltage used to operate the liquid crystal panel, wherein the DC-DC converter includes a pulse width modulation circuit which modulates a pulse width of the analog drive voltage and the gate-on voltage, a boost converter which boosts the input voltage to output the analog drive voltage, and a charge pump which boosts one of the input voltage and the analog drive voltage to output the gate-on voltage, wherein when a high voltage stress test is performed, the DC-DC converter outputs the analog drive voltage boosted to a voltage level higher than a voltage level of the analog drive voltage during a normal operation, and outputs the gate-on voltage having a voltage level substantially equal to a voltage level of the gate-on voltage during the normal operation.
