Abstract

The invention provides a flexible circuit board and its preparation method and display device, belonging to the technical field of flexible circuit boards, which can solve the problem of the existing flexible circuit boards cut from large boards because the transition area is usually bent and slender. type, it is difficult to divide when cutting, and it is difficult to make full use of large plates. The flexible circuit board of the present invention includes a first component and a second component, the first component includes a main body and a first connection area, at least one first signal line is arranged in the main body and the first connection area; the second The component includes a connector and a second connection area, the connector and the second connection area are provided with a second signal line matching the first signal line; the first connection area is connected with the second connection area, so that the first signal The wires are electrically connected to the corresponding second signal wires. The flexible circuit board of the invention can maximize the utilization rate of raw materials, improve production efficiency and reduce costs. The flexible circuit board of the present invention is suitable for various display devices.

Description

technical field [0001] The invention belongs to the technical field of flexible circuit boards, and in particular relates to a flexible circuit board, a preparation method thereof, and a display device. Background technique [0002] Flexible circuit board (FPC) is a printed circuit made of flexible insulating substrates. FPC can provide excellent electrical properties and can meet the design needs of smaller and higher-density installations. It can be bent, wound, and folded freely. It can withstand millions of dynamic bending without damaging the wires. It can be arranged arbitrarily according to the requirements of the space layout, and can be moved and stretched arbitrarily in the three-dimensional space, so as to achieve the integration of component assembly and wire connection. FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, tablet computers (PDA), digital cameras and other fields or products. [0003] FPC...
