Abstract: A display panel includes an array substrate and a color filter substrate, where the color filter substrate includes a first substrate, spacer pillars, and color filter layers, each spacer pillar is in the spacing region, and each pixel region is provided with a color filter layer. Each spacer pillar includes at least one spacer layer each made of the same material as the color filter layer in one of the pixel regions. The array substrate includes a second substrate and a support layer, where the support layer is on a side of the second substrate facing the color filter substrate, and includes a body layer and a plurality of protrusions on a side of the body layer away from the second substrate, where each protrusion is each opposite to at least one of the spacer pillars. At least one of the spacer pillars is each supported on the corresponding protrusion.

Abstract: An information management method, a device, 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: A display panel has a plurality of sub-pixel regions arranged in an array of a plurality of rows and a plurality of columns, and a light-shielding region that separates the sub-pixel regions and surrounds all the sub-pixel regions as a whole. The display panel includes: a first substrate; a light-shielding pattern layer located on the first substrate, the light-shielding pattern layer being located in the light-shielding region and covering part of the light-shielding region; a second substrate disposed opposite to the first substrate; and a light-shielding structure layer located on the second substrate, the light-shielding structure layer covering at least a region of the light-shielding region that is not covered by the light-shielding pattern layer.

Abstract: Disclosed in the present disclosure is a double-deck multi-span bridge construction method. According to the double-deck bridge construction method of the present disclosure, construction is carried out by using a method of disassembling a support jig frame in a graded and span-separated mode, an upper chord jig frame and a lower chord jig frame can be used in a recycle manner, and construction costs are reduced. In addition, a construction period of building the support jig frame is shortened, and other construction operations can be synchronously carried out on a span in which the jig frame is disassembled, for example, fire retardant coating construction can be carried out on a mounted bridge deck after the jig frame is disassembled, and the construction period of a double-deck multi-span bridge is effectively shortened.

Abstract: Disclosed is a method for Application Specific Packet Filter (ASPF) of a File Transfer Protocol (FTP), including the following steps: when a Transmission Control Protocol (TCP) connection of an FTP control channel is established, a first TCP Synchronous (TCP SYN) packet sent by a client is obtained and forwarded to an FTP server; it is detected whether a response packet from the FTP server is a TCP Synchronize-Acknowledgment (SYN+ACK) packet, and if not, the response packet is discarded; it is detected whether a response packet from the client is an ACK TCP packet, and if not, the response packet is discarded; and a data flow table is created to record and update an FTP state. A device for ASPF of a FTP is also provided. The method and device can avoid and stop the attacks from the FTP application layer, and ensure safe and reliable transmission of an FTP service.
