[0002] FPC (flexible circuit board) belongs to one of main component materials of display module, and FPC is composed of FCCL base material, cover film, reinforcing and other auxiliary materials such as ink. FPC interface type has welding type, plug-in type and board-to-board buckling type, wherein, plug-in type FPC is matched with connector on mainboard, if FPC plug-in position is not in place in assembling process, will lead to display module display abnormality or non-displaying and other problems exist, such as Figure 1 As shown, the current common practice is to design a plug-in alignment line at FPC plug-in end to assist to view whether FPC is plugged in place during assembling.

[0003] At present, FPC will change ink character into etching character in order to reduce production cost, but plug-in type FPC generally prints an ink silk screen alignment line on PI reinforcing to serve as the basis for observing and judging whether assembling is in place in order to view whether plug-in assembling is in place during assembling, since PI reinforcing color is deeper, if etching alignment line is under PI reinforcing, it is basically indistinguishable, can only do ink alignment silk screen line, therefore, there is the problem that alignment silk screen line is set on plug-in type FPC, leading to that FPC production process cannot be simplified and production cost cannot be reduced. In view of the above problems, the industry has not yet proposed an effective solution. UTILITY MODEL CONTENT

[0031] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0032] As shown in Figure 2 The present application relates to a flexible circuit board and a display device. The flexible circuit board comprises: a substrate 10; the substrate 10 refers to a carrier substrate 10, which can achieve good bearing effect; at the same time, it can also achieve good electrical connection effect between other components. Further, the substrate 10 is a soft copper foil substrate. It can be understood that it has higher flexibility and better conductivity, thereby ensuring good electrical performance.

[0033] The reinforcing layer 20 is arranged at one end of the substrate 10. By arranging the reinforcing layer 20 at the end of the substrate 10, an additional material layer for enhancing the strength, improving the durability and stability of the substrate 10 can be achieved, thereby ensuring good mechanical strength and stability of the plug-in area.

[0034] The plug-in alignment mark 30 is arranged at least at one end of the reinforcing layer 20 in a preset direction. The plug-in alignment mark 30 can help to correctly install and align the designed mark between two plug-in components (such as the connection between the FPC and the connector or plug). The plug-in alignment mark 30 appears in the form of a visual mark on the FPC or connector, which can help the operator to confirm the accuracy of the direction and position when plugging in. The preset direction can be the horizontal direction or the X-axis direction in a two-coordinate system.

[0035] The plug-in alignment mark 30 is arranged at least at one end of the reinforcing layer 20 in a preset direction. The plug-in alignment mark 30 can help to correctly install and align the designed mark between two plug-in components (such as the connection between the FPC and the connector or plug). The plug-in alignment mark 30 appears in the form of a visual mark on the FPC or connector, which can help the operator to confirm the accuracy of the direction and position when plugging in. The preset direction can be the horizontal direction or the X-axis direction in a two-coordinate system.

[0036] Improve alignment accuracy: Precise alignment marks help the connected components to achieve higher alignment accuracy, ensuring correct signal transmission and reliability of electrical connection.

[0037] By using the plug-in alignment mark 30 instead of the ink silk screen line, the PI reinforcing notch mark structure can not only play a role in alignment observation but also be easy to identify.

[0038] Specifically, the ink alignment silk screen line 40 of the PI reinforcing end of the plug-in FPC is removed and replaced by a PI reinforcing edge notch mark structure to replace the ink alignment silk screen line. This can achieve the effect of canceling the FPC ink printing and ink baking process, reducing the FPC production cycle and material use cost.

[0039] From the above description, it can be seen that the present application achieves the following technical effects:

[0040] In the embodiment of the present application, the plug-in alignment mark 30 is added to cancel the ink alignment silk screen line 40, and the plug-in alignment mark 30 is preset on the substrate 10 and at one end of the reinforcing layer 20, so as to facilitate plug-in alignment observation, and the purpose of canceling the FPC ink printing and ink baking process is achieved, thereby realizing the technical effects of reducing the FPC production cycle and material use cost, and further solving the technical problems that in order to reduce the production cost, the FPC will change the ink characters into etched characters, but in order to check whether the plug-in assembly is in place during the assembly process, the plug-in FPC generally prints an ink silk screen alignment line on the PI reinforcing layer as a basis for observing and judging whether the assembly is in place, and since the PI reinforcing layer is dark in color, the etched alignment line under the PI reinforcing layer is basically indistinguishable, and only the ink alignment line can be used, therefore, the plug-in FPC is provided with the alignment silk screen line, which causes the FPC production process to be unable to be simplified and the production cost to be unable to be reduced.

[0041] Further, the number of the plug-in alignment marks 30 is two, and the two plug-in alignment marks 30 are respectively symmetrically arranged at two ends of the reinforcing layer 20 along the preset direction. It can be understood that the plug-in components can have a consistent alignment mode when being inserted, thereby improving the precision and reliability of the connection; at the same time, the symmetric structure can further improve the recognition degree.

[0042] Further, the width of the plug-in alignment mark 30 is 0.2-0.3 mm, and the depth is 0.3-0.5 mm. It can be understood that by setting the depth and width in the above interval range, sufficient recognizable degree can be provided visually, and the operator can clearly see the alignment mark when plugging in; at the same time, it can also ensure that the strength and structure of the reinforcing layer 20 are not affected; therefore, the observation and identification are facilitated without affecting the reinforcing function of the FPC reinforcing layer.

[0043] Further, the width of the plug-in alignment mark 30 is 0.2 mm, and the depth is 0.3 mm. It can be understood that good identification effect can be achieved.

[0044] Further, the plug-in alignment mark 30 is in the form of a semi-open groove. It can be understood that it is easy to process and form; at the same time, the groove shape enhances the precision and convenience of alignment.

[0045] Further, the groove shape is U-shaped or V-shaped. It can be understood that good positioning mark and guiding effect can be ensured; at the same time, by providing a variety of shapes for selection, the needs of various use scenarios can be met.

[0046] Of course, the corresponding shape can also be set according to the actual use needs.

[0047] Further, the plug-in alignment mark 30 is arranged through the two ends of the reinforcing layer 20 and the substrate 10 in the horizontal direction respectively. It can be understood that stronger alignment can be provided during plug-in, and the entire plug-in process can be ensured to be performed according to the accurate alignment mark, avoiding deviation.

[0048] Further, the plug-in alignment mark 30 is arranged through the two ends of the reinforcing layer 20 and the substrate 10 in the horizontal direction respectively. It can be understood that stronger alignment can be provided during plug-in, and the entire plug-in process can be ensured to be performed according to the accurate alignment mark, avoiding deviation.
