Problems solved by technology
like figure 2 As shown, after the welding pads 121, 122 of the flexible circuit board 12 are welded to the welding ends 161, 162 of the flexible circuit board 16, due to the limitation of space, there is only one welding point 130 at the welding place. Since the welding area is small, Problems such as empty welding, falling off, and fracture due to bending often occur at the welding place

Abstract
The present invention discloses a flexible circuit board and a display device equipped with the same. The flexible circuit board comprises a substrate, a first soldering pad and a second soldering pad, the substrate comprises the relative first and second side edges and an end part located between the first and second side edges, and the first and second soldering pads are configured on the substrate and are arranged along the first and second side edges. The soldering pads of the flexible circuit board are arranged along the side edges of the substrate, so that the soldering area of the soldering pads and the number of the soldering points can be increased effectively on the condition of not influencing the appearance and the size of the flexible circuit board, the soldering strength is improved greatly, and the problems that the soldering positions are in missing soldering, fall off, break due to bending, etc., are avoided.
Description
technical field [0001] The invention relates to a flexible circuit board, in particular to a flexible circuit board with at least two welding pads arranged along the side of the substrate and a display device equipped with the flexible circuit board. Background technique [0002] Due to the advantages of thinness, light weight, low power consumption, no radiation pollution, and compatibility with semiconductor process technology, liquid crystal display devices have been widely used in various electronic devices, such as notebook computers, Mobile phones, digital cameras, personal digital assistants, etc. The liquid crystal display device provides light to the display panel through the light emitting module to display images. For the existing liquid crystal display device, the flexible circuit board of the light-emitting module needs to be soldered to the flexible circuit board of the display panel for unified wiring. [0003] Please refer to figure 1 as well as figure 2...
