摘要： A signal driver includes a first driver, a second driver, an on-timing control circuit, and an off-timing control circuit. The first driver is configured to generate a first driving pulse signal by inverting and driving an input pulse signal. The second driver is configured to generate a second driving pulse signal by inverting and driving the first driving pulse signal. The on-timing control circuit is configured to pull-up drive or pull-down drive the first driving pulse signal based on a first on-timing control signal, a second on-timing control signal, and the input pulse signal. The off-timing control circuit is configured to pull-up drive or pull-down drive the second driving pulse signal based on a first off-timing control signal, a second off-timing control signal, and the first driving pulse signal.
