Abstract:
1. A driving apparatus for a display device comprising: 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 having a value 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 a plurality of gate signals to be applied to a plurality of pixels of a display panel of the display device based on the scanning start signal and the clock signal, wherein the clock signal generator comprises: wherein the third voltage is higher than the first voltage and lower than the second voltage, wherein each of the pre-clock signal and the charge sharing control signal has a first value and a second value, the first value is larger than the second value, wherein the value of the clock signal is changed from the first voltage to the third voltage and then from the third voltage to the second voltage, and wherein the value of the clock signal is changed from the second voltage to the third voltage when the pre-clock signal has the first value and the charge sharing control signal changes from the second value to the first value, and then from the third voltage to the first voltage when the charge sharing control signal has the first value and the pre-clock signal changes from first value to the second value.
