    Abstract: A bezel structure of a touch screen is disclosed by the invention, including: a BM portion provided at an end on a back surface of the substrate; a bonding area arranged on the BM portion and provided with a plurality of metal leads and a plurality of transparent conductive solder pads, each of the plurality of transparent conductive solder pads being electrically connected with corresponding one metal lead of the plurality of metal leads; a first insulating photoresist layer arranged between the plurality of transparent conductive solder pads and the plurality of metal leads in a thickness direction of the substrate, the transparent conductive solder pads being electrically connected with corresponding metal leads via jumper holes provided in the first insulating photoresist layer; and a plurality of transparent conductive edge-routing wires arranged on the back surface of the substrate, at both lateral sides thereof, each of the plurality of transparent conductive edge-routing wires extending to the bonding area and being constructed at a terminal end thereof as corresponding one of the plurality of transparent conductive solder pads located within the bonding area. A touch screen having the bezel structure, a display device having the touch screen, and a method for manufacturing the bezel structure of the touch screen are also disclosed by the invention. Transparent conductive material is formed as edge-routing wires so as to realize a bezel-free technology, providing an improved user experience.

    Abstract: A circuit board, a preparation method thereof, and an electronic device are provided. The circuit board includes: a substrate, defining a first through-hole; a metal block, embedded in the first through-hole and fixedly connected to the substrate; a conductive line layer, arranged on at least one side surface of the substrate; wherein the conductive line layer partially covers an opening of the first through-hole on a corresponding side surface of the substrate; and a conductive channel, penetrating the conductive line layer and the metal block in turn. The conductive channel comprises a second through-hole and a conductive medium plated on a wall of the second through-hole; an end of the conductive medium is connected to the conductive line layer, and another end of the conductive medium is connected to the metal block.
