Abstract: A driving apparatus includes a timing controller, a gate driver, and a pulse width controller. The timing controller generates a gate output enable signal having a width which is used for defining on-voltage widths of gate driving signals. The gate driver sequentially outputs the gate driving signals corresponds to a plurality of gate lines. The gate driver is controlled to prevent overlapping of the gate driving signals. The pulse width controller includes a signal generator and a converter. The signal generator receives two of the gate driving signals from two adjacent gate lines, compares the two gate driving signals, and generates a detection signal that detects an overlapping area of the two gate driving signals. The converter converts the detection signal to a pulse width control signal and feeds the pulse width control signal back to the timing controller. The timing controller receives the pulse width control signal and adjusts the width of the gate output enable signal.
