Abstract: A display panel and a splicing panel are provided. A driving substrate includes a second surface, and the second surface is a side surface of a driving substrate. A second encapsulation structure includes at least one coating layer and at least one adhesive layer. One of the coating layer and the adhesive layer directly covers the second surface of the driving substrate. In a vertical direction of the second surface of the driving substrate, the coating layer and the adhesive layer are alternately arranged, and both the coating layer and the adhesive layer are organic layers. The coating layer and the adhesive layer using organic materials can, flatten a roughness of the second surface, so as to improve an integrity of the coating layer and the adhesive layer, thereby improving an encapsulation performance.

Abstract: A method for preparing aluminum foam sandwich material by rotating friction extrusion and electromagnetic pulse hybrid process includes: step 1: preparing the filler; step 2: processing the filler to prepare a plurality of preforms; step 3: clamping and fixing the plurality of preforms to form a preform assembly; step 4: welding the panel on the surface of the preform assembly to form an non-foaming sandwich material; step 5: heating and foaming the non-foaming sandwich material through a foaming mold; step 6: insulating the foaming mold after completion of foaming; injecting cooling water into the foaming mold after completion of insulation to maintain pressure and shape, forming the aluminum foam sandwich material of the required shape. The aluminum foam sandwich material produced by this method has good interface bonding, no adverse interface reaction, high bending resistance, impact resistance, and excellent sound absorption and insulation properties.

Abstract: A message processing method can help protect confidential information, or other information that one desires not to disclose, from being disclosed, spread, or leaked, and improve the security of such protected information. A chat interface comprising at least one chat message is displayed. A target operation instruction is received that indicates a target operation that is to be executed on a target chat message. The target operation is executed in response to the target operation instruction. Protection processing on the protected content is performed when the target chat message includes a protected content, thereby protecting the information from being further disclosed and improving security of the information.
