An information management method, a device, a system and a medium. The information management method applied to a first terminal, including: sending an information acquisition request to a server, so that the server responds to the information acquisition request and sends visitor information to the first terminal; receiving the visitor information sent by the server; generating card information according to the visitor information; and sending the card information to an electronic card, so that the electronic card displays the card information.

Information management method, device, system and medium

Disclosed are an electronic signboard and a wall hanging device. The electronic signboard includes a display device and a wall hanging device. The display device is provided with a first fitting portion, and the wall hanging device is provided with a second fitting portion detachably connected to the first fitting portion. The wall hanging device is further provided a fixing surface via which the wall hanging device is fixed to a mounting base.

Electronic signboard and wall hanging device

Embodiments of the present disclosure provide an electronic paper, a display device, and a driving method. A plurality of first half-cup structures each includes charged dye particles with a single electric property are provided on the first driving backplane, a plurality of second half-cup structures each includes charged dye particles with a single electric property are provided on the second driving backplane; one first half-cup structure and the opposite second half-cup structures constitute a micro-cup structure, a electric property of the charged dye particles in the first half-cup structure is opposite to that in the second half-cup structure in the same micro-cup structure; a cross-sectional area of the respective second half-cup structures gradually decreases in a direction pointing from the second driving backplane to the first driving backplane; and a cross-sectional area of the respective first half-cup structures gradually decreases in an opposite direction.

Electronic paper, display device, and driving method

A method of driving an electronic paper display apparatus includes: providing a preprocessing signal in the first pulse signal to the first electrode in the display stage of the first image display stage, so that the first particles and the third particles are mixed, and the first particles and the third particles are closer to a display side of the display apparatus than the second particles; and providing a first sub-pulse signal in the first pulse signal to the first electrode in the display stage of the first image display stage after providing the preprocessing signal, so that the third particles are closer to the display side of the display apparatus than the first particles and the second particles and the microcup displays the third color.
