1. A control device, comprising:
a controller, configured to control a gate driver of a display panel, wherein the gate driver is configured to drive a plurality of scan lines of the display panel, the controller selects at least one first selected frame and at least one second selected frame in each frame group, an adjacent position between a first partition and a second partition of the display panel corresponds to a corresponding time point in each frame of the at least one first selected frame and a corresponding time point in each frame of the at least one second selected frame, the controller transmits a reset pulse to the gate driver at the corresponding time point in each frame of the at least one second selected frame to clear a scanning pulse in the gate driver, and the controller cancels the reset pulse at the corresponding time point in each frame of the at least one first selected frame,
wherein the controller transmits a single reset pulse to the gate driver in each frame of the at least one first selected frame to clear the scanning pulse in the gate driver, and the controller transmits a plurality of reset pulses to the gate driver in each frame of the at least one second selected frame to clear the scanning pulse in the gate driver at different time points.
