1. A display device, comprising:
a display panel configured to display an image frame; and
a driving circuit coupled to the display panel and configured to output a gate signal to drive the display panel to display the image frame during a driving period,
wherein the driving period comprises a first period, a second period, and a third period, the gate signal has a first voltage level during the first period and a second voltage level during the second period, and the second voltage level is greater than the first voltage level,
wherein during the driving period, the driving circuit is further configured to output a source signal to drive the display panel to display the image frame,
wherein the source signal has a voltage level during the third period, the voltage level is within a second voltage range, and the second voltage range comprises the first voltage range,
wherein a lower limit value of the second voltage range is smaller than a lower limit value of the first voltage range, and an upper limit value of the second voltage range is greater than or equal to an upper limit value of the first voltage range.
