1. A display device, comprising:
a display panel, having a plurality of first pixel rows and a plurality of second pixel rows, wherein the first pixel rows are arranged alternately with the second pixel rows, respectively;
a first gate driver, sequentially driving the first pixel rows using a first driving method according to a plurality of first control signals that are sequentially enabled in a first time interval;
a second gate driver, sequentially driving the second pixel rows using the first driving method according to a plurality of second control signals that are sequentially enabled in a second time interval following the first time interval;
a third gate driver, sequentially driving the first pixel rows using a second driving method according to a plurality of third control signals that are sequentially enabled in a third time interval following the second time interval; and
a fourth gate driver, sequentially driving the second pixel rows using the second driving method according to a plurality of fourth control signals that are sequentially enabled in a fourth time interval following the third time interval,
wherein one of the first driving method and the second driving method is a pulse amplitude modulation (PAM) driving method, and the other of the first driving method and the second driving method is a pulse-width modulation (PWM) driving method,
wherein in a pixel period of the display device, enabling states of the plurality of third control signals and the plurality of fourth control signals occur after enabling states of the plurality of first control signals and the plurality of second control signals.
