Abstract
A driving apparatus for a display device includes: a signal controller that generates a pre-clock signal, a charge sharing control signal and a scanning start signal; a clock signal generator that generates a clock signal swinging between a first voltage and a second voltage based on the pre-clock signal and the charge sharing control signal; and a gate driver that generates gate signals based on the scanning start signal and the clock signal, where the clock signal generator includes: a voltage generator that generates a third voltage; and a clock generator that receives one of the first to third voltages in response to the pre-clock signal and the charge sharing control signal, and outputs an output signal based on the one of the first to third voltages as the clock signal, where the third voltage is lower than the first voltage and higher than the second voltage.
