The circuit assembly comprises a printed circuit board assembly. The printed circuit board assembly comprises: a first circuit board; a second circuit board; and a third circuit board interconnected with the first circuit board and the second circuit board. The circuit assembly comprises a battery, and an output transducer for providing the audio signal, wherein the printed circuit board assembly is folded about the battery and the output transducer.

A display device includes a display substrate, a first connection wiring, and a signal wiring. The display substrate includes a display area and a pad area disposed outside the display area. The first connection wiring is disposed on the pad area of the display substrate. The signal wiring is disposed on the first connection wiring of the pad area of the display substrate. The signal wiring is electrically connected to the first connection wiring through a first contact hole. The signal wiring includes at least one first opening at least partially surrounded by the signal wiring in a plan view. The first opening is disposed closer to the display area than the first contact hole.

A battery pack includes: a battery cell including first and second surfaces arranged at opposite sides and at which first and second electrodes are respectively located, and a side surface connecting the first and second surfaces to each other; a first circuit board arranged on the first surface and connected to the first electrode; a second circuit board arranged on the second surface; a first flexible line extending from a first side of the first circuit board to the second circuit board while surrounding a portion of the side surface of the battery cell; and a second flexible line extending from a second side of the first circuit board to the second surface of the battery cell while surrounding another portion of the side surface of the battery cell and connected to the second electrode.

A display device includes: a display substrate including a display area and a pad area disposed around the display area; a signal wiring disposed over the display area and the pad area on the display substrate; at least one wiring pad including: a pad pattern portion disposed on the pad area of the display substrate and electrically connected to the signal wiring; and a separation pattern portion separated from the pad pattern portion by a separation space; and a printed circuit board attached to the pad area of the display substrate, the printed circuit board including a lead wiring connected to the at least one wiring pad.

The present disclosure provides a display device and a splicing screen, relating to the field of display equipment. The display device includes a liquid crystal display screen, a lamp board, and a printed circuit board. The lamp board includes a flexible circuit board and a plurality of light-emitting diodes. The flexible circuit board includes a first part and a second part connected to each other. The light-emitting diodes are disposed on the first part, and the first part is disposed on an edge of a front surface of the liquid crystal display screen. The second part extends outside of the liquid crystal display screen to a rear surface of the liquid crystal display screen and is detachably plugged into the printed circuit board disposed on the rear surface. Since the first part is disposed on the edge of the front surface of the liquid crystal display, a picture displayed on the light-emitting diodes can block an edge region of the liquid crystal display screen. Therefore, when a plurality of display devices is spliced into a splicing screen, split seams can be reduced or even eliminated, thereby improving visual effect.

A flexible circuit board includes a main board, a first connecting plate, and a second connecting plate; a side surface of the first connecting plate is connected to a first side surface of the main board, and an included angle between the main board and the first connecting plate is a first preset angle; a side surface of the second connecting plate is connected to the first side surface of the main board, and an included angle between the main board and the second connecting plate is a second preset angle; and the first preset angle and the second preset angle are both greater than 0 degree and less than 180 degrees.

A method of fabricating an electromagnet includes obtaining a first flexible PCB that includes one or more first conductive coiled traces and obtaining a second flexible PCB that includes one or more second conductive coiled traces. The first flexible PCB is bent into a shape having at least one curve or corner. With the first flexible PCB having been bent into the shape, the second flexible PCB is then bent into the shape: the second flexible PCB is positioned adjacent to the first flexible PCB to conform with the first flexible PCB.
