Abstract
The method includes, in a low-frequency driving mode where a keeping phase is arranged between two active phases, providing a light-emitting control signal with a duty cycle of a % to a pixel circuit during the active phase; and performing first and second switches on the light-emitting control signal during the keeping phase. The first switch is performed before the second switch. Panel brightness at the first switch is higher than panel brightness at the second switch. The duty cycle of the light-emitting control signal is b % after the second switch. b>a. A total duration of active levels of the light-emitting control signal within one frame after the first switch is between a total duration of active levels of the light-emitting control signal with the duty cycle of a % and a total duration of active levels of the light-emitting control signal with the duty cycle of b % within one frame.
