The present invention provides an electronic device, including a storage module, a sensing module, a processing module, a driving module, and a display module. The storage module stores a plurality of frames. The sensing module outputs a sensing signal according to an action by the electronic device. The processing module outputs a transmitting signal according to the sensing signal. The transmitting signal corresponds to a first screen-refresh rate. The driving module determines the subsequent frame according to either the transmitting signal or a driving signal before the current frame ends. The driving signal corresponds to a second screen-refresh rate. The display module displays a display picture corresponding to the subsequent frame according to the subsequent frame and either the first screen-refresh rate or the second screen-refresh rate.
