Abstract: A magnetic attraction type lens-replaceable eyeglasses, comprising a frame and lenses. A connector for fixedly connecting the lenses to the frame is disposed at a bridge of the frame. The connector is detachably connected to the frame. The connector and the frame are in magnetic attraction cooperation. Fixing pins capable of penetrating through the lenses and used for limiting the swing of the lenses are disposed on the side, in contact with the lenses, of the connector. By using the detachable connector, the lenses are fixed to the frame. By means of magnetic attraction cooperation, the lenses can be relatively easy to replace. Meanwhile, by using a design of positioning pins, it can be ensured that the lenses mounted on the frame will not swing or shift.

Abstract: The present disclosure provides a semiconductor structure and a method for forming the semiconductor structure. The method includes: providing a substrate including a device region and a guard ring region surrounding the device region; and forming a power device in the device region and forming a guard ring in the guard ring region, wherein the guard ring is doped with a first dopant ion that is formed by a partial doping process used in a formation of the power device, and a conductivity type of the first dopant ion in the guard ring is different from a device type of the power device. Since the guard ring is formed by the necessary doping process used in forming the power device, additional photomask process and doping process for forming the guard ring is omitted, effectively reducing process steps and process costs.

Abstract: An angle adjustment assembly includes a first connecting piece including first side plates, a second connecting piece including second side plate, and a limiting rod. The first side plates are hinged to the second side plates. The first side plates include a through hole that is arc-shaped and centered at a hinge joint of the first side plates and the second side plates. A path of the through hole has at least one expansion groove. The limiting rod is axially movably connected with a corresponding second side plate. The limiting rod includes a first sections and a second section. A diameter of the first section is smaller than a diameter of the second section. A size of the first section matches a size of the through hole. A size of the second section matches a size of the at least one expansion groove.

Abstract: The present disclosure relates to a display panel, a display screen, and a display terminal. The display panel includes a substrate, a pixel-defining layer disposed on the substrate, and an isolation structure disposed on the pixel-defining layer. The isolation structure includes at least two layer structures stacked in sequence along a direction perpendicular to a surface of the substrate. At least one of the at least two layer structures has a width varied continuously or intermittently along an extending direction of the isolation structure. The extending direction of the isolation structure is parallel to the surface of the substrate. The width of the layer structure refers to a size of a projection, along a direction perpendicular to the extending direction, of the layer structure on a plane coplanar with the surface of the substrate.
