Abstract: A power voltage generator includes a voltage sensor and a power controller. The voltage sensor is configured to sense a first voltage in a first charge sharing period of a gate clock signal and a second voltage in a second charge sharing period of the gate clock signal. The power breaker is configured to disconnect a power based on the first voltage and the second voltage.

Abstract: A display device includes a timing controller which transmits a vertical clock signal having rising edges and falling edges to a gate driver and a gate driver which receives the vertical clock signal, to generate a first gate clock signal and a first inverted gate clock signal in accordance with one of the rising edges and the falling edges of the vertical clock signal, and to generate a second gate clock signal and a second inverted gate clock signal in accordance with a remaining one of the rising edges and the falling edges of the vertical clock signal.
