In one embodiment, for one sub-pixel 20 of the plurality of sub-pixels 20, an interval between the first time when the light from the sub-pixel 20 may not be shifted by the pixel shift unit 30 to form the first display pixel 401 and the second time when the light from the sub-pixel 20 may be shifted by the pixel shift unit 30 to form the second display pixel 402 may be smaller than or equal to about 100 ms. An important characteristic of eyes is visual inertia. That is, once an optical image is formed on a retina, vision will maintain a sense of the optical image for a limited period of time. This physiological phenomenon is called visual persistence. For a light stimulation with medium intensity, visual persistence is about 100 ms. In one embodiment, the interval between the first time and the second time may be smaller than or equal to about 100 ms. Correspondingly, when the first display pixels 401 and the second display pixels 402 formed at different time are viewed by human eyes, they may be considered as a video or an animation effect. The visual resolution of the display module 000 and the resolution of the display panel may be improved.
