Problems solved by technology
[0004] If the marking line is used as the alignment mark, due to the manufacturing tolerance of the marking line, it is easy to cause the deviation of the installed module components; and due to the thickness of the marking line itself, when there is a high requirement for the flatness of the FPC, due to The thickness of the marking line itself is likely to cause poor contact between the FPC in the area around the marking line and other components during installation
[0005] If the copper wire is used as the alignment mark, since the color of the copper wire is similar to that of the FPC, the copper wire set on the FPC is not easy to be seen, which brings great difficulties to the alignment

Embodiment Construction
[0045] The technical solutions of the embodiments of the present invention will be described in detail below through the drawings and specific examples. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of the present invention, rather than the embodiments of the present invention. The limitation of the technical solution, in the case of no conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.
[0046] In the first aspect, in order to avoid poor contact between the FPC in the area around the silk screen line and other components during installation due to the thickness of the silk screen line itself, such as Figure 4 As shown, the embodiment of the present invention provides a flexible circuit board 1 , the flexible circuit board 1 is provided with at least one markin...

Embodiments of the present invention provide a flexible circuit board and a display device. By forming a functional layer in the groove of the flexible circuit board and using the functional layer as an alignment mark, it is avoided that the thickness of the silk screen line itself is likely to cause the area around the silk screen line to be distorted. Poor contact between FPC and other components when installed. The flexible circuit board is provided with at least one marking area, and the marking area includes at least one groove; the groove is provided with a functional layer formed by fillers.
Description
technical field [0001] The invention relates to the field of flexible circuit boards, in particular to a flexible circuit board and a display device. Background technique [0002] Because FPC (Flexible Printed Circuit, flexible circuit board) has excellent characteristics such as light weight, thin thickness and free bending and folding, it is favored. Its flexible circuit board is made of polyester film or support. embedded circuit. [0003] When installing module components on the FPC, it is generally necessary to design an alignment mark on the FPC. The alignment mark is used to install the module component as a position reference standard to avoid errors in the position of the installed module component. In the prior art, marking wires or copper wires are usually added to the FPC as alignment marks. [0004] If the marking line is used as the alignment mark, due to the manufacturing tolerance of the marking line, it is easy to cause the deviation of the installed modul...
