  • Patent number: 7764257
    Abstract: Gate voltage controlling apparatus and method wherein a gate voltage may be applied to a gate driver sequentially from a lower voltage toward a higher voltage to stably drive and protect the gate driver, thereby minimizing any defects in the gate driver. In the gate controlling apparatus, a power supply generates at least two gate voltages having a different voltage level. A gate driver generates a scanning pulse that selects a display line using the at least two gate voltages having a different voltage level. A gate voltage controller supplies the gate voltages to the gate driver in sequence from a lower voltage toward a higher voltage.
