Abstract: The present disclosure provides an energy storage power supply. The energy storage power supply includes a shell and a lighting device. The shell is provided with a lighting chamber. The lighting chamber is provided with a first light outlet. The lighting device includes a light-emitting component and a condensing lens. The lighting device is arranged in the lighting chamber. A light-emitting surface of the light-emitting component is arranged in a manner of facing the condensing lens and the first light outlet. The condensing lens is configured to condense light emitted by the light-emitting component to form a small light beam with a long illumination distance. Through the above structure, when a user uses the energy storage power supply in the open air or other occasions, purposes of a longer illumination distance and a clearer viewing field, which greatly improves the practicality and user experience of the energy storage power supply.

Abstract: A rollable display device is provided. The rollable display device includes a flexible display panel, a storage mechanism, and an actuating mechanism. The storage mechanism includes a rotary component. The rotary component includes a rotary member and a rotating shaft member rotatably connected to the rotary member. The aforesaid rollable display device allows the flexible display panel to realize bidirectional stretching under movement of the actuating mechanism, thereby increasing a rolled-up radius of the flexible display panel.
