Abstract: 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.

Abstract: In a specific embodiment, the present invention provides an LCOS device. The device has a semiconductor substrate, e.g., silicon substrate. The device has a transistor formed within the semiconductor substrate. The transistor has a first node, a second node, and a row node. A first capacitor structure is coupled to the transistor. The first capacitor structure includes a first polysilicon layer coupled to the second node of the transistor. The first capacitor structure also has a first capacitor insulating layer overlying the first polysilicon layer and a second polysilicon layer overlying the insulating layer. The second polysilicon layer is coupled to a reference potential, e.g., ground. The device has a second capacitor structure coupled to the transistor. The second capacitor structure has a first metal layer coupled to the reference potential, a second capacitor insulating layer, and a second metal layer coupled to the second node of the transistor. A pixel electrode comprises the first metal layer.
