The present disclosure provides a display panel including a plurality of pixels, each of which includes at least one sub-pixel. Each sub-pixel includes a color reflection box and a control unit configured to control a color to be displayed by the color reflection box. The control unit is configured to, in the presence of ambient light, control a position of a light-entering surface of a shielding member in the corresponding color reflection box relative to a light-entering surface of a case in accordance with a display image at a corresponding position, so as to enable the color reflection box to display a color of the light-entering surface of the shielding member or a color of a colored material.
