    Abstract: An exemplary control method of an output signal (e.g., from a timing controller in a flat panel display device) is adapted to be operative with a first signal with multiple pulses. In the control method, during a first time segment including part of the pulses of the first signal, a first enable signal is provided passing through a transmission path after a first time length from a rising edge of each of the part of the pulses. During a second time segment including another part of the pulses of the first signal, a second enable signal is provided passing through a part of the transmission path after a second time length from a rising edge of each of the another part of the pulses. The first time length is shorter than the second time length.
