Abstract: Disclosed are a vibration sound device for an electronic product and the electronic product. The vibration sound device comprises a first housing, a magnetic assembly, a coil assembly and a second housing. The first housing includes a cavity and is opened at one side thereof. An interaction force is generated between the magnetic assembly in the first housing and the coil assembly on the second housing to drive the vibration sound device to vibrate so as to generate a sound. According to the present disclosure, the magnetic assembly and the coil assembly are configured in a sandwiched structure, so that the overall height of the vibration sound device is reduced, and thus space utilization of the electronic device is improved.

Abstract: A display panel includes a drive backplane; a first electrode layer, including a plurality of first electrodes distributed in an array; a leakage cut-off layer, provided on the same surface of the drive backplane as the first electrode layer; a light-emitting function layer, at least partially covering a top of the leakage cut-off layer and a partial area of the first electrode; and a second electrode, covering the light-emitting function layer; where the second electrode includes a plurality of flat parts and a separating part located between the plurality of flat parts; the separating part includes a protruding area and a first recessed area, the first recessed area is located between the protruding area and the flat part, and a bottom of the first recessed area is located on a side of the leakage cut-off layer away from the drive backplane.

Abstract: A driving backplane includes: a base; a first conductive layer disposed on the base, the first conductive layer including at least one first signal line; a first insulating layer disposed on a side of the first conductive layer away from the base; a second conductive layer disposed on a side of the first insulating layer away from the first conductive layer, the second conductive layer including at least one second signal line. Each first signal line and a second signal line constitute a signal line pair. In the signal line pair, extending directions of the first signal line and the second signal line are the same, an orthogonal projection of the first signal line on the base and an orthogonal projection of the second signal line on the base have a first overlapping region, and the second signal line is coupled to the first signal line.

Abstract: A method for extracting significant texture features of a B-ultrasonic image and application thereof discloses a channel attention mechanism network, i.e. a context activation residual network, which is designed to effectively model the B-ultrasonic liver fibrosis texture information, and which uses the global context information to strengthen important texture features and suppress useless texture features, such that the deep residual network can capture more significant texture information in the B-ultrasonic images. The process can be mainly divided into two phases: training and testing. During the training phase, the context activation residual network may be trained by using the B-ultrasonic image blocks as input and the pathological results of liver biopsy as labels. During the testing phase, the B-ultrasonic image blocks may be input into the trained non-invasive liver fibrosis diagnosis model to obtain the liver fibrosis staging result for each ultrasonic image.
