Abstract:
Provided are a display panel and a display device. The display panel includes multiple cascaded gate drive units. Each gate drive unit includes a shift register unit and an inverted unit. The inverted unit is electrically connected to the shift register unit. A scan output terminal of the shift register unit is electrically connected to one scan line. An inverted scan output terminal of the inverted unit is electrically connected to one inverted scan line. The scan output terminal of the shift register unit outputs a first effective pulse signal. The inverted scan output terminal of the inverted unit outputs a second effective pulse signal. A time period corresponding to the first effective pulse signal at least partially overlaps a time period corresponding to the second effective pulse signal, and the type of the first effective pulse signal is opposite to the type of the second effective pulse signal.
